The Great KingMax PC2700 debate. Let's end it.

[MadMan007]

OK, I have been reading the various posts about the Kingmax PC2700 for the last week. I ordered some from CrazyPC over the weekend which are supposedly "-05" marking, I will see tomorrow and update this post when I read the markings.

After seeing f155's new topic (http://forums.overclockers.ws/vb/showthread.php?s=&threadid=58830) I became a tad concerned and decided to do some more digging. We can see here (http://www.kingmax.com.tw/product/module_a.html#ddr) on the Kingmax site the various DDR modules (just scroll down.) Scanning the part numbers this is what I find:

First two characters="MP" for all 184-pin (non-registered or non-ECC, I assume) modules.

Third character="D" for 266MHz modules; "L" for 300MHz modules. There is no listing for 333MHz modules (PC2700) which I find odd.

Fourth and fifth characters="A8" for 128MB modules; "B6" for 256MB modules.

There are two ending sequences: "2D-683" (which only appears on the first two listings) and "2D-68KX2" (all others.) I am not sure what the difference is here, as all the 266MHz modules (regardless of the end sequence) are listed as 133MHz DDR 7.5ns CL=2.5 in their .pdf datasheets. All 300 MHz modules (which only have the "2D-68KX2" marking) are listed as 150MHz DDR 6.6ns CL=2.5. Again, no listing of 333MHz modules. Also, in the first paragraph, it says the 300MHz modules have three decoupling capacitors (whatever that is :) ) in parallel for each DRAM, while the 266MHz modules have only two. I am sure you could see these if you looked on the module PCB as SMT devices. This is regardless of ending sequence.

Combined with Flu!d's post from another thread (http://forums.overclockers.ws/vb/showthread.php?s=&threadid=53370) that I will quote: I pulled a stick out so I could get the full information.

The sticker is marked:
MPMB62D-68KX3
DDR-333 256 CL 2.5

The Chips are marked:
Kingmax
KDL684T4A2A
-05

Hope this helps.

So, clearly there are differences in the markings between the true 333MHz modules and the others. 1) The third character for the 333MHz (at least the ones fluid has) is "M." Anyone else see a pattern? 300MHz="L", 333MHz="M." Simple alphabetic progression. 2) The chips end in "-05." As for the rest of the chip markings I have no idea, as none of the .pdf's go into that.

To sum up, I am convinced that a marking of MPM indicates a true 333MHz module, while MPL indicates a 300MHz module. As for the "-05" on the end there is no conclusive evidence that I can find. As I said elsewhere, unless someone here is a Kingmax engineer, we cannot truly prove that -7a is not designed for 333MHz. It may just be a production run change or something. The numbers may or may not correspond to a ns rating, even if other RAM types do. I know we like to think it does, and usually it does, but I am trying to do a scientific-type proof here, and not "guess" at anything (not to diss anyone else here...)

Anyway, it would be helpful if f155 would post what his sticker and DRAMs have written on them. And if anyone else has Kingmax DDR of any speed, feel free to post your module sticker/DRAM silkscreens so we can have more evidence.

Sincerely,
MadMan

Go look here nice pic's.

If you ask me a employee at kingmax didn't have his coffee and or something and put a bunch of the 2700 part number stickers on the 2400 parts and no one noticed.

[MadMan007]

Thanks, but do you have any Kingmax RAM that you can post the specs of? Because that thread is no more or less informative than the many others that already exist here...

[Taylor]

One thing I'm sure of- if it say 5 on it then we have what Kingmax is claiming to be their -5ns stuff. If it says 7a, who knows, and they're exchanging them readily enough, so why not get what you ordered

[f155mph]

Well I am still waiting for Kingmax and Crazypc to email me back. As for the sticker on the ram, mine don't have any. I'll let you guys know how this turn out. Thanks for trying madman!

The Chips are marked:

[dropadrop]

Just received my kingmax 333 memory, and the sticker says what your sticker says, but the chips end with a marking -06!

KDL684T4A2A-06 to be precise... I wonder what's going on? Maby it just depends on the patch and has nothing to do with the timings?

[MadMan007]

So, UPS man pulls up and I am all in anticipation and what not. He drops the package off and scurries back to his truck (we have a pre-set "drop-off" policy with UPS.) I run upstairs and tear into the package which was quite large for RAM BTW-nice packaging. I open one of the static bags and carefully pull out the stick. Well, the sticker says MPM at least, one part down. Squinting at the chips, I read the last two digits:

"-06"

:eh?: WTF??? :eh?: lol, then I read drop's post. *sigh* now I am thoroughly confused and may give up...anticipating rising RAM prices I bought this now for a system I will be building in about a month, no mobo to test on :( Oh well, one last try by contacting Kingmax to get a definitve answer. Unfortunately, crazyPC never actually advertised the ns rating on their website, so unless Kingmax says otherwise I am keeping this crap, and hoping for the best.

To summarize, my sticker says the same as Placid's, RAM silkscreen is the same except for last two numbers, which are -06.
This is probably what I get for starting this thread to find the *Truth* :p

Edit: [mumble] "hey, maybe -06 is the newest revision, cuz 6>5. Yeah, yeah, that's it!" [/psychotic mumbling]

[MadMan007]

I am going to post my full sticker info here, as it also has a lot number (L/N) and a serial number (S/N)

sticker says:
-------------------------
MPMB62D-68KX3
L/N: E1C0039 MAA
S/N: 050263
DDR-333 256MB CL2.5
-------------------------

I am willing to bet a major organ that a lot of the discrepancies have to do with the L/N. I would guess that drop's and my L/N are closer than the other peeps who have "-05." What is yours dropadrop and Placid?

At this point I am just waiting to hear back from Kingmax but I am near the point of not caring. If this stuff runs@166MHz FSB then it is all good, if not then I am RMA'ing it under the "lifetime warranty."

[f155mph]

Madman,

Please post your result soon!!! Also from what i read on you post. Your ram came with the manufacture sticker. I think I should RMA my cause I don't have the manufacture sticker on it. Without the sticker I don't have warranty??? Am I right??? If so this is total BS.

:mad: :eek:

[Placid]

Your the second person I know of f155mph who got kingmax from crazy pc without a kingmax sticker the link in my post above shows what the other guy got.

The kingmax memory is installed and I put heat spreaders on it so I can't get the other numbers, sorry.

[Placid]

I found a pic of the sticker on a stick with the -5 chips.

http://www2.overclockers.co.nz/ocnz/misc/ddrguide/kingmax333/sticker.jpg

[MadMan007]

Placid:
Great! now all we have to do is decipher their lot number coding!! HAHAHA

f155:
Definitely return it and get ones with Kingmax stickers. Just call or email CrazyPC, their customer service seems to be really fast. And YES YOU NEED THE STICKER FOR WARRANTY!! lol, they say "Warranty Void if Removed." That way even if a reseller goes under you can go back to the manufacturer.

Also ask them to double-check the numbers on the RAM and send you the good stuff. Remember though, you catch twice as many flies with honey...in other words, unless they are a$$holes, be nice. I used to work in retail and some of the clowns in the store would f* with people who were mean. I do find it suspicious, tho, that they said they were out of stock but sent it to you anyway? Isn't that what happened? Maybe they removed the sticker, who knows? But they are definitely not alone when it comes to strangely marked Kingmax modules...

Keeping my fingers crossed for a month to test this crap may give me a cramp...lol

[f155mph]

I just called and they said they will get back with me.:(

[MadMan007]

I wouldn't stress. As far as I can tell they have good customer service according to www.resellerratings.com (which I always check b4 ordering anything.) Did you actually talk to them or just leave a message. I am curious to see what they say, maybe they will hook me up with some "-05" sweetness too.
All I would tell them is that 1) the RAM you ordered did not have the sticker. 2) It was marked "-07a" (or whatever) which is not PC2700 according to Kingmax (hehe, sometimes you gotta fudge a little :) )
GL and keep us updated!

[f155mph]

Ok, I just got an email from Nick saying that he will exchange my Kingmax:D . It seem that they got a few stick from Kingmax without the sticker on it. This is really making Kingmax smell fishy! I took some pic with my camera and email it to them to prove that there were no sticker on them. I also told them i want to buy another one. The price will go up more from what I heard.

All this trouble for stupid memory:rolleyes:

[MadMan007]

So much for this thread being "A Repository Of Kingmax PC2700 memory" or whatever, but it is good to hear they are hooking you up. I would be surprised if they had screwed you. No way to get such a high resellerrating when you f* people over.

I am wondering if it was the same "Nick" fellow who emailed me this:Hi,
I've spoken with Kingmax tech support and they tells us that they are
all
5ns memory whether or not marked 75 70a or 05. Personally, I can't
vouch for
this as I have no method of verifying if this is correct. However, the
current batch we have in-stock is marked 05. This batch should last us
the
next few days.

Regards,
Nick
CrazyPC.com

mmm, riiiiight....that is why I got -06 and you got -7a or whatever? Oh, well...tell me what you get this time!! :) Oh, and did you ask him about the numbers on the end? Would be good if he said "Yes, we will send you -xx" or something so you can be sure you are getting exactly what you want. And if he sends you -05, I am gonna exchange mine too!! hehe...

[Amair_sc]

I am with you here on this fabulous CrazyPc adventure :(

[MadMan007]

I am with you here on this fabulous CrazyPc adventure

How's that now? I take it you got some RAM from them as well. Come on, tell us your story!!
Seriously though, what markings does your RAM have on it, etc, etc.
BTW I still think it is a Kingmax or distributor issue. We happened to use the same vendor, but this has happened from others as well according to other posts...so I am not anti-crazypc. Let's just see what f155 gets back...

[dropadrop]

I would'nt blame your vendor. I bought mine in finland and got one with the -06 chips as I mentioned before... The sticker thing sounds fishy though. Did you get it in some closed bag so that the vendor can't see the ram? I guess they are pretty busy at the shop though...
I can't really see some guy who did'nt drink his morning coffee (as mentioned as a suggestion on some post) labeling so many diferant ram batches with the wrong stickers... What I would really like to hear are some benchmarks from people who first got the -07 ram and had them swithched to the -05's! That could close this issue I imagine. If somebody tells me they get the same benchmarks and fsb with both of them that would point to the direction that they are the same.

Just wanted to add to this that my chips don't have any of the markings on this mail from kingmax... I would have imagined they would have mentioned the -06 batch too?

[Amair_sc]

I haven't gotten mine yet, the shipping to Canada is a bit longer (and 4* as expensive). I decided to buy mine when I saw the "Nick" E-mail saying that the sticks they had in stock where marked -05. Obviously it didnt turn out exactly that way for you guys. I'll wait and see what is marked on my chips :D .

[flood]

My Kingmax PC2700 memory is on the way. When it arrives, I'll post all the details...should be Tuesday. I specifically ordered -5ns so I'm hoping that's what I get. I ordered it from PowerUp Inc. in TX and it shipped yesterday.

[Amair_sc]

Finnaly the wait is over, I just received it from UPS and it is marked... -05 :D, ahhh, now I can sleep again ;).

[MadMan007]

Finnaly the wait is over, I just received it from UPS and it is marked... -05 , ahhh, now I can sleep again .

/me stomps my feet and throws a fit "NOT FAIR NOT FAIR NOT FAIR!!" :D heh, after I posted the email from them saying "oh yeah, all the stuff we have is -05." Well, considering *I* was the one that got the email maybe I should swap my stuff...

On another note: the only references to Kingmax stuff from other manufacturers (ie not reviews and stuff) I can find is on the Sis Website (http://www.sis.com/ddr/ddr333.htm) where they list the "validated" DDR modules. And the -06 is the only validated Kingmax 333MHz module. NEENER-NEENER-NEENER!! But only at CL3. :( It is also listed on the 266MHz page, but also at CL3? :eh?:

I am gonna wait a week or so to get an email from Kingmax regarding this. I will see what f155 gets back from them, and if I feel the need to exchange I can use the email as ammo.

I just really wish I could test this...maybe I will goto the local shop and see if they'll let me pound on a mobo to try it out :)

[Amair_sc]

I would try and test it too :). Sincerely the "Nick" E-mail could prove to be great ammo in case of "misunderstandings" :cool: .

Good Luck bud :beer:!

[f155mph]

Madman,

I called Nick today and got my order straighten out. I order 2 sticks of the PC2700 with the -05. I hope I get it. He said he have them. I am RMAing my tomorrow, and get a refund on it. If he ship it out tomorrow I should get it Monday. I'll keep you posted. Nick is a nice guy. You might want to get it replace like NOW cause Nick told me they are raising the price like this weekend.

[Amair_sc]

Wow, that's awesome!!! The CrazyPC crew really seem like a very friendly and professional bunch, they will certainly get more business from me in the future :) (glad to have found a nice retailer since here, in Canada, we computer enthusiasts sometimes get *frustrated* by the *selection* our local dealers have)

[MadMan007]

Hmmm...maybe I will do it tomorrow then. As far as raising the prices, I understand they have to, but at the same time f* that if they are gonna try to charge me more. I was promised one item and got another, you know?

Besides, if I return the -06, they can sell it at their new higher price anyway, so it would all cancel out for them.

Did you talk to Nick on the phone I take it? And did you have to ask to talk to him? Every time I call (twice) I had to leave a message. They did call back though.

Heck, I might as well exchange it...

[f155mph]

Yes I talk to Nick directly, he pick up the phone. Are you calling the 1-888 number? I call the number and no one pick up so I dial the number with the 248 area code. Yesterday I called after 5:30 and there was someone there still. So you might want to try that number instead.

[MadMan007]

Yeah I called the (248) area code number. It was the only one I could find :) Thanks, I guess I will call tomorrow.

[dropadrop]

what a way to end the discussion... (referring to the topic of this thread) :eek:

[MadMan007]

what a way to end the discussion... (referring to the topic of this thread)

Yeah, no joke. I was really hoping this thread would turn into a database of Kingmax DDR modules, but not enough people posted or even have the PC2700 ones to make it any more informative than other threads already dealing with it. LOL, it turned into a personal thread about exchanging RAM with CrazyPC. :rolleyes:

[xgman]

I was sent a pdf on the 2700 by kingmax sales. It is not on their website, but at least the original ver. of this part # MPMB62D-68KX3 is a 7.5ns part according to the pdf. The -05's I have read 6ns in CTSPD, so that may be why you are now seeing -6 parts. I do not beleive that there are any actual 5ns parts and that they run at 6ns where 2700 should anyway. The 7a parts were probably 7.5ns chips, but unless someone runs CTSPD that has one, there is no way of knowing. What did CTSPD say the -6 chip speed was?

[MadMan007]

I don't know what CTSPD says cuz I have no mobo yet . :) I bought the RAM now for a system I will build over the next month b/c I anticipated rising RAM prices.

Some others here, especially Fluid, feel that CTSPD is no good for DDR b/c it reads the RAM speed straight off of the Northbridge. I always thought CTSPD read the SPD module on the DIMMs. You are right though, it would be interesting to see what it says about the -07a and -75 DRAMs that are called PC2700. Who knows, maybe they would show something different? We will never really know for sure until someone tries it...

A quick poll: should I return my -06 and ask for some -05 or not? I have not seen anyone write about their experiences with the -06, so they are kind of an "unknown quantity."

[SuperFLyJimmy]

So what I am reading here is that if you have the -07a ram it isn't true 5ns ram. I ordered mine from Crazy PC because they were the only place with the "5ns" ram in stock. I have also read in the forum someone spoke with Kingmax and they said the ram was just labeld wrong and it is all true 5ns ram.
What should I do, Should I just keep it, or should I send it back to Crazy PC for a exchange.???
SOmeone give me a good idea here.

[MadMan007]

Unlock your processor and see how high you can get the FSB with them at 2-2-2 memory timings. If this fellow has some of the oddly marked Kingmax, maybe we can find some answers. What markings do you have BTW?

[PilotPC]

I bought KingMax PC2700 from Newegg.com thinking it was the good stuff (DDR333) and after reading about it being "fake" DDR333 on another forum, I took a look at mine. Sure enough, it is the "-7" 7ns stuff. I paid $77 per 256mb stick for mine. Now it's up to $95 I believe. I'm kinda ****ed off, but I don't do any real wild overclocking, so I don't think I'll go through the trouble of RMA'ing it back to them. Something is definitely fishy about this all though. It should be classified as "fraud". That's like selling a "Pentium 1.4" running at 1.2. Not cool. I'm currently overclocking my XP1600 to 1.53Ghz using a 145Mhz FSB and it runs with no problems at all. Getting 2200&2100mb/s Sandra memory scores.

[SuperFLyJimmy]

I have the -07a ram, Currently i can't get any higher tha 153, but I believe this is due to my Raid setup. Usually the sstme Blue screens me with a file causing windows to shut down. The mOBO manual says Raid isn't
to cooperative with FSB OC.
But whenever I run SI Sandra( the memory bench) my system either locks up or reboots itself. BUt it runs all the other with no problem. ANy Ideas why it does this?

[PilotPC]

You may need to run some more juice (volts) to your RAM. Does your motherboard support that? Mine defaults at 2.55v, but I bumped it up to 2.65 at 145Mhz FSB.

I was going to get some RAM sinks from Thermalrite, but I think these KingMax dimms are not as wide as regular dimms, so I'm not sure they'll fit.

[SuperFLyJimmy]

no it doesnt have the volt increase

I also paid $77, on Dec. 26th from Kommax, and I also got the 7a stuff. But RMAing it was easy- not a hassle at all. The only reason I ordered it was to get the -5ns ram, and when I called Kommax, they said to send it back with a not explaining my position and what I wanted them to do. He said if it was not my own error they would "make it right", and they did- I overnighted it to them, on one day, they got it the next day and shipped the right stuff back out hours later. I got it the following day, and it came with the reciept for them having credited my account back the cost of shipping it back to them. I was so pleased with how swiftly they resolved the issue that a few days ago I ordered two more sticks. In the "comments" field of the online order form I asked them to be sure and send the -5ns chips, and so we'll see probably today if that worked. I'll go check my box in a little bit and see what's there.

You ordered a specific product, and they did not send that product to you, so you should feel comfortable demanding that the proper part be delivered.

[f155mph]

Wahoo I got my stuff today!!! Got the 05 with the factory sticker. Nick is a great guy. Glad I got all this straighten out, all I need now is a new mobo and cpu.

Northwood or XP 2200?:eh?:

[TranceBear]

If you want some more pics from owners, here ya go.

[TranceBear]

and a close-up

[SuperFLyJimmy]

so is the -07a 5ns ram or not. Why would kingmax sell the tiny BGA as some being 5ns and others not? I thought all the 333 from Kingmax was 5ns. i haven't seen any different anywhere.

I emailed Crazy PC telling them they sent me the -07a instead of the -05a which I wanted and I haven't heard anything back yet. How long did it take fo ryou to get your response.?

[Sonny]

Just got mine for a new system that I should have up in a few weeks:D

[Sonny]

$90.00 USD from a local shop. No shipping, no tax & I get to play around with some computers:D

[Sonny]

Yes they are the right modules;)

[SuperFLyJimmy]

And the answer to my question is????

[xgman]

Again, the -05 is 6ns ram not 5ns ram. I have yet to see any program id the chips as 5ns ram. Anyone have different info?

[Sonny]

I assume you are talking to me. One question for you first though: do the Kingmax stickers on your RAM say MPM or MPL? Just curious...if they say MPM then they are only 300MHz rated for sure.

To answer you: I got the response within 24 hours. I emailed in the middle of the day and had a response the next mid-morning when I checked my email again. Also, if you call the (248) area code # they will call you back. Heh, I wonder if Nick is getting ****ed yet exchanging all this RAM. Unfortunately, they will probably sell it to someone else who is happy enough if the sticker says "DDR333." Oh well....

[SuperFLyJimmy]

yeah thanks. Hell witem for gettin ****ed. the shouldnt cheat people. Yes they say MPM#######. SO i got Scre*ed huh?
Yup Ill be calling them later. Thanks for the help.

[xgman]

Where on the kingmax website does it say any of their modules are 5ns? I actually have a pdf spec data sheet that one of their salesmen sent me on this part # and it says that they are actually 7.5ns chips. (thgis may be the original spec and since changed) I have only seen the -05's, which I have 2 of, read as 6ns. If anyone can point to a "kingmax" web page where it says 5ns, please show me. I now resellers are advertising it that way, but I beleive that they are 6ns chips and not 5.

[MadMan007]

I would not assume it was the vendor's fault. This has happened at numerous places, it seems Kingmax may be supplying them with wrong memory types. Remember, be nice and you'll get a pleasant response back. Be mean and they might too....

Yeah, good point I have searched the Kingmax site high and low. The problem is that they only have pdf data sheets for up to 300MHz PC2400 modules. So it is kind of hard to know exactly what the deal with the 333MHz parts is when there is no data to go by. I just want chips that run >=a66MHz, pref@cas 2, and the -05's seem to do that. Kind of like different CPU steppings, ya know?

[SuperFLyJimmy]

Im sure it isn't the vendors fault. But f they sell it they will replace it all the same. I have no problems with the vendors, and I am always nice as long as they are. I use to be a vendor and I know what it is like.

[SuperFLyJimmy]

Yup mine isn't the 5ns 333mhz stuff. I was at 155fsb and was getting errors all the time at 2-2-2. I set it to 2.5 and they were gone. My stick has the MPM and -07a on it. I called Crazy PC about a replacement. Emailed and left a message. Hopefully they will respect that they sent me the wrong stuff and replace it. My Order slip even says. Kingmax PC2700 333Mhz Tiny BGA which it obviously isn't. Let yall know what happens.

[MadMan007]

Hehe oops I made a mistake in my post Superfly. It should be:
MPL=300MHz for sure.
MPM=333MHz according to Kingmax.

I need to relearn the alphabet it seems... M comes after L :)

[SuperFLyJimmy]

So what does this mean then. I have the ram with the MPM on the Number representing the 333Mhz. BUt I also have the -07a on the ram. Does this mean it is 333Mhz 7.5ns ram. The other link at the begining of the post said that the ram was just mistyped and that Kingmax just uses ram from Nanyo(I believe). So do I have the right stuff or not. I know at 155FSB I have to turn it down to 2.5 because at 2 it gives me errors and blue screens.
BUt it will run the DrMemory test for 10+ loops without a problem.
I have called CrazyPC for a exchange and I am waiting to hear back, they were closed when I called. I think I will just exchange it anyway for the -05a stuff. Just for the piece of mind that i have what I paid for. Also the comp won't even boot at 160FSB.

[xgman]

Like I said, I have the data sheet on the MPM62D-68KX3 and it clearly says 7.5ns not 5 not 6. However, the -05 parts ARE 6ns parts. I have ran several memory id's on them and they all say the same thing. I suppose it is possible to program the spd differently from the actual chip speed, but I doubt they did it that way. I just think they have gotten better memory chips since the original data sheet was produced. Unfortunately they should have changed the part #. Kingmax has tried to claim that the 07a # was just a mistake, but I am sure that the chips are different than the 5's and I have also heard that now there are some marked -06 as well, probably a better # since the -05 is actually reading as 6ns.

Many memory manufacturers commonly change the chips without changing the part # (as in Corsair 2700) so maybe this is the common practice. "Let the buyer beware!"

Superfly,

I got mine exchanged from CrazyPC. There shouldn't be any problem, just be nice about it. You might want to speak to Nick directly.

[SuperFLyJimmy]

So then if those are 6ns how can Kingmax make a claim they are 5ns. And if the-05a and -07a aren't 5ns then what is. The -06 are new and couldn't be the 5ns because kingmax has been claiming 5ns for over 2 months now. SO what gives. Is it possibel your programs are showing the ram wrong. I have the -07a chips. Give me a link to a progrma and I will tell you what mine show. I currently have CTSPd but it won't work. Says can't recognize my chipset.

[SuperFLyJimmy]

Okay I spoke with Crazy PC and they said the Kingmax Tech support said the ram is just marked wrong and the -07a and everything else is true 5ns ram. However, He did give me the option to exchange the ram for the-05a ram if I had purchased it in the last 30days. Which is sweet and heck ya I am exchanging it. Just thought I would post what they say Kingmax has said about the different labeled supposedly "5ns" ram.

[PilotPC]

Is there any way to REALLY find out if it's 5ns or 7ns even though they are marked wrong? I mean if programs are coming up showing it as 7ns, it's gotta be 7ns. Programs don't care about external markings. ;)

[herbal'|']

If you check the programming of CTSPD, it reads it's info from the NORTHBRIDGE, not the ram chips. This is why it misreads the 5ns chips as 6ns chips. It is not acurate and definately not grounds to claim that Kingmax has printed the chips wrong.

[Placid]

If it was 5ns it should run at 200mhz at or close to default voltage.

Neither of the two I have will go over 180mhz with any settings.

Another brand will go to 195 so I doubt its the board.
It is sold as 2700ddr that would suggest a 6ns chip.

If it was sold a higher than 2700 then I would have a gripe but so far everyone who I have seen with this memory can get it to run at 166mhz.

[montano]

I received my Kingmax today from NewEgg.com.... and it's MPM as well as -05. I have bought lots of items from them and they are the best online retailer I have ever used. I think all the old -07a modules are done with.

[flood]

I agree with montano...I think all of the -06 & -07 may have 'worked itself out of the system'. I just received my Kingmax DDR-333 from PowerUp Inc. (www.puicorp.com) and it is MPM as well as -05 screened on the chips themselves.
I paid $100 for 256MB and the price seems to be holding for the past week. Hurry up and get yours!
By the way...I don't know if anybody noticed this, but Kingmax has posted the 'official' info regarding DDR-333 on their website. http://www.kingmax.com.tw/product/datasheet/MPMB62D-68KX3-MAA.pdf

Oh soooooo nice!

[xgman]

Folks, corrcet me if I am wrong, but NOWHERE on the Kingmax web site does it say that the DDR333 are 5ns chips. This shows up only on reseller sites. The only official documentation on these parts that I have seen (sent to me by a Kingmax sales rep) says that the parts are 7.5ns parts. I beleive that they are now actually 6ns parts if they are marked -05. I do not beleive the story about the mismarked -07a chips after reviewing my data sheet on the part #.

Link to motherboard monitor download to check memory speed.

http://mbm.livewiredev.com/

install, click on icon on task bar, go to system info in the program and click on the icon of the memory chip in the bottom of the window. This should read the speed of the memory if CTSPD doesn't work.

Someone please read the 07a parts and let us know. The 05 parts read 6ns.

Look at page 7 of the above referenced pdf. It says clock cycle time min 7.5ns max 10ns. Where does it say 5 or even 6?

CL2.0 = 10 /12/ns/5
CL2.5 = 7.5/12/ns/5

Why would CL2 need only 10ns if CL2.5 needs a 7.5ns?

[SuperFLyJimmy]

I have -07a marked ram and MBM5 says the max supported speed is 6ns at cas2 and min is 7.5 @ CL x-1. It also says my memory speed is 166Mhz. SO it is displaying things correctly.
If someone tells me how to insert the Picture here I will so all can see. My -07a Chips are running at 166Mhz and support 6ns.

[xgman]

I am definetly not an expert and this doesn't make any sense to me either. Their ddr300 also has this seemingly backwards spec except that the high on the 300 is 12 instead of 10. On page 12 of the DDR333 pdf, it again states the "ddr cycle time from clock @cas 2.5 = 7.5ns" and "ddr cycle time @cas latency of 2 at 10ns"

The point is that it does not say 5ns or even 6ns, so I'm not sure why the resellers are calling it 5ns when kingmax data sheets do not.

This is the same readout as my -05's, so maybe Kingmax's statement that they are just mismarked may be true after all.

Since PDF is not reliable for the right DATA then it can not be used to prove that the modules are 7.5ns. Even if it doesnt say 5ns or 6ns you cant rule it out by your own reasoning now can you:beer:

[SuperFLyJimmy]

On a side note. I thought i would put my Benchmarks on from the -07a marked ram. I am running it at 2-2-2-5. Got a bench of 2282MB/s Int BUffered and 2162MB/x Float Buffered. Both are

[SuperFLyJimmy]

Yes that would work better huh. Now lets turn it around....

[SuperFLyJimmy]

Great. Excellent wonderful hillarious even. Yeah I know about the alt print. then paint then save then save as then save as whatever then internet then internet forum then internet message then internet forum message type then internet forum message type browse then internet forum message type browse select picture then internet forum message type browse picture submit. Right or did I miss something.

[SuperFLyJimmy]

Uh....Yeah I would. Cause I looked at help under windows and it told me about it. That is how I did the first one. i don't know why the white is there. But I used the ALT+PRTSCN button. Its because after I copy it I use MS PAint to save it. It ahs a white box you put your picture into. My picture wasn't as big as the white box. So when I saved it it saved everything including the white box. seeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

[SuperFLyJimmy]

and here is this one

[SuperFLyJimmy]

Don't have a problem. Just didn't want to do it. Do I have to do everything to your specifications whenever I decide to do something? If so please feel free to send me a copy of your expectations and specifications on everything in this world and I will do my best to obide by them for as long as I see fit.
Oh and here is your picture

**Edited by Moderator**

Nope, here is NOT your picture. That jpeg you attached is rude, uncalled for, and defintely not something we allow, or want in our Forums.

Do NOT post it again, please. If we don't allow verbal (typed) profanity, we certainly will not tolerate visual profanity.

LOL, jimmy hijacked my thread!! :)

Anyway, unless you were responding to the voices in your head for the last 6 or so posts, if someone PM's you I suggest you PM them back rather than post one side of the conversation. It makes you look, um, what's the word...ah, yes, psycho.

Those are some nice benches, thanks for posting them with the -07a stuff you have. So, are you running 166MHz @ CAS 2 stable now? If so, you may want to update your sig.

[f155mph]

Madman,

So did you get your -05?

[SuperFLyJimmy]

No Im not running at 166Mhz. It won't even boot at 160Mhz. Kinda upsetting. At cas2 at 157 it gives me problems so I had to down it to cas2.5. I sent back the ram and ordered the -05 stuff.
They told me Kingmax made a mistake and misprinted al the ram. I kindly said" Yeah well give me the correctly marked stuff" they said Okay. SO it should be here sometime early this week. Hope tomorrow. Then I will re test and see were I sit at. Hopefully closer to the 2700MB/s. We'll see.

[SuperFLyJimmy]

And as for the last 6 or so post I was responding to sonny. BUt he removed his post for some reason. We had it going back and forth about posting pic on the forum. Im not crazy. Oh and the picture I had up wasn't rude. I was just telling Sonny he was #1 in my book:) I don't have a first fingure so I had to use what was available.

[dropadrop]

I think I can finally end this post! I found a review of the kingmax pc2700 memory, and there is a photo of it next to a kingmax2400 one. If you look at the pictures on the bottom it is pretty clear that the last number does really refer to nano-seconds, and that I have one with -6 nanosecond chips!

http://www.pcpowerzone.co.uk/reviews.php?id=53&page=1

[xgman]

Just because this chip says -05 and the reviewer called it 5ns memory doesn't make it so. I still say that the 05's are 6ns chips. That is what all the memory programs read it as and again Kingmax has not published it as 5ns ram anywhere. That asside, it does perform pretty well. I have 2 256 sticks of the 05 stuff in a kr7a with a MP1800 running at 1733, fsb 166 or 167 at cas 222, 4way on, but command rate at 2T. 1-T won't boot at least with 2 sticks anyway, with similar Sandra scores as the reviewer in the 2222/2112 range. It would probably go higher with using only 1 stick, but I need the extra ram for graphics work. The FSB can go higher if I clock down but I find it most stable here.

[SuperFLyJimmy]

Well I got my -05 marked ram today. Recap I had the -07a and sent it back. After tests of course. Ran MBM5 and found it to read exactly the same as the -07a stuff. Benchmards was alittle higher. off the bat. Benches on the old ram is in the previous posts above. SO from what I see there is no difference so far in the ram. -07a and -05 is the same so far. Will let ya know after I tweak it some and see where it sits.

[xgman]

2 sticks of the 05 stuff is now running stable at cas 2,command rate 2t at 171 which benches in the 24XX / 22XX range. It actually seems like pretty decent stuff, especially since using 2 sticks together.
