Good oc'ing DDR2?

[dylskee]

I'm putting together my new setup and need some help with memory. So far i've got an 840D, P5WD2 Premium, 6800U. I would like to get some good oc'ing memory & keep it to $200.~$220. for a gig (2x512) I'm leaning toward the Mushkin pc2-6400, but i'm seeing a lot of good reviews on PQI. Thanks for any help. :)

[crimedog]

i'd say pqi has the winner because it's 2gb, but the mushkin is the king of 1gb

ps farther down this section i made a thread with my ocing results with pqi and some micron d9 (basis of the mushkin, although the mushkin does much better)

[sicloan]

the pqi is definatley awsome. I can get this stuff to ddr800 spec at 5 5 5 15 easy.

[dylskee]

I think i might do better with a gig of Mushkin DDR2 800 pc2 6400 (http://www.newegg.com/Product/Product.asp?Item=N82E16820146431)

Than 2 gig of pgi DDR2 667 pc2 5400 (http://www.newegg.com/Product/Product.asp?Item=N82E16820141211)

Is that a correct assumption?

[dylskee]

Ok, i'm minutes away from ticking the "check out" tab @ newegg and i'm still undecided with the memory. Would you recommend the 2GB of pqi or the 1GB of Mushkin? Decisions Decisions! :shrug:

[Sneaky]

im gonna toss in my .02 for a 2x512 (1gb) kit of OCZ DDR2-667/PC2-5400 Platinum EB - its probably one of the best sets of DDR2 around, and it will easily OC to DDR2-800 and beyond according to a number of OCZ employees and product owners

link: http://www.topmicrousa.com/ocz26671024ebdcpe-k.html (edit: had wrong link before)

newegg used to have it for $240, but it disappeared :-/

IMO, you really cant have better DDR2 ram than that if you have a budget that allows it


edit #2: here's OCZ's DDR2-667 Gold which has slightly looser timings than the platinum, but is still awesome ram: http://www.topmicrousa.com/ocz26671024eldcge-k.html (and its also pretty damn affordable)

[dylskee]

Hey sneaky, yeah i can't find it either at the egg. $284. is a little more than i wanted to dish out, but i might consider it. I would rather get everything from the egg. I'm ordering my psu mobo, memory, and AS5. Cha Ching!!!! I was hoping to get some decent memory for $220. and under. :shrug:

EDIT: Damn, thats pretty good, and a very good price too!!!! :drool: This stuff is pretty good huh?

EDIT#2: I found This at newegg (http://www.newegg.com/Product/Product.asp?Item=N82E16820227043) but it's only a single stick, is that ok or is it better to have 2 sticks?

[Sneaky]

which stuff, the gold? cause thats kickass ram too, just with looser timings, but should OC about the same as the platinum

my friend just got a 2gb set of the OCZ Gold DDR2-667 and that stuff is smokin' on his new P4 670 rig he just built

Yeah the gold, But is a 1GB ok, or should i get the 2x512?

[Sneaky]

i'd suggest the 2x512 unless you plan on picking up a second 1gb stick later for 2gb total

[crimedog]

the mushkin is better than the ocz... and the ocz has been discontinued for quite some time now too.

when i was making the descision you are making now this is how i thought about it. at the maximum usable speed 1:1 (because you don't really gain anything on a divider) you're choosing between 2gb of 4-4-4 or 1gb of 4-2-2. I say maximum is around 350mhz, and to hit that high you'd need a good cooling system and a chip with unlocked multi. Now, considering that the 2gb of 4-4-4 is less money than the 1gb of 4-2-2, the choice was pretty clear to me.

neither is a bad choice, it's up to you.

edit: you have a 840d, if you're lucky enough to get 4ghz that's 250mhz fsb. the pqi should do 4-3-3 at that speed, at least mine does.

Am i going to have a hard time hitting 4GHz on this chip with my xp-120?? Damn, i hit 4.1GHz with a s478 3.0E! Well, as far as the memory i have already added the pqi to my cart, i figured if it doesn't do well i'll just sell it and save a few more $'s and try something else.

[crimedog]

there's supposed to be new ddr2 around the corner so let's hope that's good :) hopefully the 90nm process is fast and cheap :p

edit: sadly, i heard otherwise after posting :'(

[dylskee]

Did you have an 840D crimedog? I thought you did, but i see a 560es in your sig???

[crimedog]

no i've never had a dual core, can't expect a dual core to clock as high as a single core though ;)

DOH! :bang head

Intel's multiplexing, thanks to Rambus ingenuity, would work a lot better w/ 4 sticks. another word if you are interested in 2 gig, 4x512 would be better than 2x1gig, unlike AMD.
just a thought.

Well, apparently all Intel guru's here ignored the importance of 4 dimms multiplexing of DDR2 (if you know what it means :confused: ) that I brought up in my post.
This means- If you are interested in DDR2, make sure your mobo has 4 slots and populate all 4dimms for better perfomance.
here are couple of links to enlighten you.
guru's included.

well i wouldn't call myself a "guru" but i just threw in an extra two sticks of ram and at the same speed (2x1gb and 2x512mb) and all my tests are reporting a slight loss in performance. not much of a loss, but definitely no gain.

And having 4 sticks MAY reduce your OC because with 4 sticks theres a better chance of 1 stick not being able to run AS fast as the others.

No offense but this information is just laughible. Where are your sources with the proof to your claims. Rambus has almost nothing to do with current P4 designs.

EDIT: What in the hell is multiplexing? :confused: and where the hell did you come up with that? Sounds like some kind of new-age workout like jazzercize. lol

[3DFlyer]

I could entertain the thought of 4 being better if there some proof of efficiency, and a perfectly matched set of modules, but to this day I have never heard of, nor have I seen a system run better with 4 modules than it did with 2.

There are also electrical looses involved also, and some slight resistence issues with spreading more metal out over four dimms, but that is another discussion.

I would have to see some numbers. Up until this point I have seen no person report they got an increase in performance using 4 dimms over 2.

The last time I read about rambus, they were all but totally out of the picture.

[d94]

get the 2 gigs of pqi :d

try 4x256 and you will see the difference. I would suggest to you finding an intell forum and hearing what they say. not here by the way.
also the 4 sticks must be same ic, manufac., and size.
PS: Rambus's memory logic's is written all over Dram, DDR and for that matter, DDR2. Rambus is in your PC if you look harder. :cool:

I suggest you doing your homework on intel before making that statement.
Multiplexing has to do w/ memory adressing and dynamic refresh rate of DDR2
Familiarize yourself w/ the subject, and if no luck, i will provide you w/ more links/info.
thanks

I have these http://www.newegg.com/Product/Product.asp?Item=N82E16820220144.

Kinda pricey compared to the other listed but they appear to oc very well but my results are limited do to my crappy chipset (hurry up 975x :)).

I get 3-2-2-8 @ 533Mhz, 3-3-3-8 @ 600Mhz and can boot into bios 4-3-3-8 @ (710MHZ).

If you could only do 600mhz w/ decent timing, i would suggest to just get
DDR2 533, or 667 w/ tighter timing that could also be less expensive.

On the side note, and not to hijack this thread, I have the links below that prove my point about 4dimms better performance on intel platform.
the links may be old stuff and on DDR1 but same would apply to DDR2
thanks

ochungry i'm curious what you're talking about, i did a google search on 'multiplexing intel' and the most relevant thing i got was about wireless. also, the four dimms yielding better performance, do you have any links for ddr2/9xx chipsets? i wish i had four sticks of the same type to test :(

[batboy]

I have personally compared 2X512 to 4X256 DDR RAM in an Intel system and there was no noticeable performance difference. In fact, for overclocking when you use 4 sticks you run a greater risk of 1 stick being slower than the rest which sometimes hurts performance.

OChungry, you have been previously warned about arguing and hijacking threads. Let it drop. Go start your own thread to discuss your "unique RAM theories" if you want.

Back on topic. You can't go wrong with the Mushkin performance DDR2.

this thread was about best performance DDR2.
I provided several links for the poster in this regard.
why don’t you drop your threats once for all. It is you and your buddies trying to hijack this thread by dragging on, and on and on trying to discredit me.
Is this a trend of Intel fanboys or is it just you and your buddies?
Now I showed the proof that 4dimms better performance. Is it so hard for you to accept it?
If you prove otherwise, show some links, instead of the usual asenining remarks.

it just asks me to sign into msn, then create an account

by the way, no one is attacking you. we're just trying to figure out wtf you're talking about.

batboy and i have tested it, isn't that a little more important than these links about ddr1 and socket 478?

Ok, try this link (ftp://download.intel.com/design/intarch/applnots/27052003.pdf), it should work.
