View Full Version : Is this BH5 ram?
I just bought a gig of BH 5 ram off a guy here in the classifieds. It is KingstonHyperX pc3000 with blue heatspreaders. I thought that BH5 chips were CAS2 not 2.5. I guess my next step is to take off the heatspreaders and look. I tried to run them at 240fsb at 2-2-2-8 on 3.14 volts with the VR-pomona grabber mod but I got a checksum error pc800e.
If you know more about BH5 mem chips speak!:)
Take of the HS to make sure they are BH-5. From what I see, they really don't seem to be BH5 material ATM.
Try to run DDR400 @ 2-2-2-6 with stock Vdimm.

Look at his pic, he is trying 200 FSB....

The guy I bought these from claimed they ran stable ay 2-2-2-11 250fsb @ 3.1
There is only a selection as high as 8 in my for cycle time in my bios.

You must remember though that he has a different system than you do. Where his system might be stable at that speed, your system might not like that speed. Also, the RAM might mot work as well with the components in your system as well as they do in his system. Just something to think about.
As was listed above, try and get your system stable at 200FSB using 2-2-2-X timings. Once you can do that, move up from there.

I understand that. My system is stable at 250fsb...proven time after time. I am going to take off the heatspreaders and look at the mem moduls.

Let's have a show of hands of guys out there who can do this with their BH-5? I have one stick of XMS3500 that can do this, but at SC on a P4 board.
If it sounds too good to be true . . . . . I'm surprised you didn't get this from Ebay.
I tried to run them at 240fsb at 2-2-2-8 on 3.14 volts with the VR-pomona grabber mod but I got a checksum error pc800e.
Yeah, I tried the pomona grabber thing on my P4C800-D where I get 3.26 volts on my multimeter, but none of my BH-5/BH-6 respond. Despite what some has said, I don't think the VTT scales up with VDIMM on the mod on this board. Same ram has done 250+, 1:1, 2-2-2-5 on Epox boards with the same voltage. I also think it's a DC issue on the Asus board, as SC the ram can do that 3D stable, but not two sticks.
'Course you need to try that ram on an AMD board, maybe it will do 250 in synch at 2-2-2-11 there, at 3.1 volts :rolleyes:. Remember, it's HARDER overclocking BH-5 on AMD boards :p. While it's possible he did that on a DFI Infinity board (where it's much easier - but more likely at 3.3 volts), that ram should do at least around 225-228, 2-2-2-5 on the NF7-S or P4 boards, at maybe 2.9-3.0 volts.
OK, so I had high hopes. Most OC'ers do. I would be happy if I could get this mem to 240fsb with tighter timing than my pc4000 (3-3-3-8). I had some Corsair pc3500 BH5 that did 240fsb last year, but alas, I sold it. Here is the best closeup I could get of the ram chips.

Those are BH-5 fosho, intriguing. The beauty

within lies massive powah

Here is what I have on my KHX PC3000 chips and I know they are BH-5.

If the guy you bought it from says he was running 2,2,2,11 then he is an AMD dude and might not of been running them dual channel. Intel dual channel systems are tougher to O/C than single channel AMD systems. Most Intel folks run 2,2,2,5 timings.
Here is mine at 3.2v with the tightest timings.

Here is mine at 3.2v with the RAS to CAS slightly relaxed.

If you want 250 FSB, try 2,3,2,6 at 3.2v.
Thanks batboy & tatuya...allright all of you fellas!:D
I feel better now that I know they are indeed BH5. I will try 3.2v next and the mem timings you suggested batboy. I will have to manually adjust the pot on my PCP&C 510w psu to that level (*edit* no I won't I wasn't thinking there for a minuite) and then re-intall the Vr-pomona...it screwed my mobo at 3.1v last time, I got bios checksum error.
Welp, I got the BH5 up to 240fsb on batboy's suggested timings 2-2-2-5 on 3.2v but right when I was gonna hit the "printscreen" button my rig crashed. I'm gonna try the RAS to CAS Delay at 3 this time and see if that doesn't help.

no you dont have gaurenteed BH5, if it were under 318 they would be. but yours are 328. meaning they may or may not be. you could "just" have CH6.
Nice! That was it! I changed the ras to cas delay to 3 and so far I'm stable...I need to run a loop of 3dmark03 first.
Here is the BH5 pc3000 @ 240fsb on 2-3-2-5 timings.
^^
Holy...jee..z..us..
I wish I could hit stuff that high /cries :(.
Here is a shot of pc4000 at the same 240fsb but with 3-3-3-8 timings.
I just tried 245fsb 3 times and it was crash city! Batboy, what else do you recommend to get past 240fsb?

I have 4 sticks of BH5 that do between 239-243 at 2-2-2-5 :D I just got another stick. Time to rip off the heatspreader :D Anyone have a link to that jpeg which explains which D-45 chips are BH5 and which aren't? IIRC as said above it's anything lower than 318 right?
Out of the second row of numbers or is it the 3rd row?

This new mem has helped me break 9k on my X800 pro at stock! Before I was at 8800 stock. Now with an OC on my x800 I'll see if I can break 10k!!
Anything above 240 is the luck of the dice. When your vdimm is set at 3.2v, what is the measured voltage?

Right on guys! I gained the re-branded KHX PC3000 chip information from Stevil in a thread at XS. He is indeed very knowledgeable.
krag, did the person guarantee dual-channel at 250 FSB or just one stick? Because dual-channel is much harder. Also, all 512MB sticks of KHX PC3000 is double-sided, which does not like CPC at all. Nice 3DMark03 score :)
violineb, 0302 is the date. So you have BH-5 :D.
WooooHHhooooooooo! First time I've broke 10k onions!
Ahhhh man its feels nice....its good to be kraggy!:D

I'm at 3.26v on the multi-meter reading. And I have a 80mm fan blowing right on the mem. My PCP&C 510w psu has an adjustable 3.3v pot on it and it goes further...I think to 3.6v. If I turn that up will I be able to acess the extra 0.3v through the VR? I'm right at max on the trimmer now.

Another note krag, the person you bought the ram from could have easily tested it on a DFI Ultra Infinity with CPC off. In that case 2-2-2-11 250fsb @ 3.1 is no sweat :).
Just for future clarification. KHX PC3000 can come in:
Original Winbond BH-5 chips
Re-branded by Kingston: DW45, DW50, or DW60
DW45 is BH-5 before 0318, mostly likely CH-5 afterwards, but also possibly BH-5
DW50 is guaranteed BH-5
DW60 is guaranteed BH-6 (not common)

I would bet that if more voltage doesn't help, it's probably the fact that they're 512mb sticks.

i have some kingston hyper x 3000 bh-5's.
i have 10 (yes 10!) 256 mb sticks just chilling, heat spreders removed and verified :P
waiting until i have 50 posts to put them in the for sale section
:eek:
Why doesn't anyone ever seem to have 512 MB sticks, heh.

Hope you have better luck than me... nobody want mine.
Hey peeps, check out this sweet mod to increase the 3.3v line to 3.65v! (http://www.bleedinedge.com/guides/psu_3.3v_mod/psu_3.3v_mod_pg1.html)
I am thinking seriously about doing it to my psu cause this BH-5 ain't even breaking a sweat at 3.3v!!!:eek:
I wonder what is considered safe voltage for oc'ed BH-5?

I know that you guys already got the info as to which codes mean what on the KHX, but here is a link to a thread with it, in case you want to save it for future reference.
The second link is to a list of Winbond based ram (BH-5, BH-6 & CH-5) that I found while doing a search on google for bh-5 ram. It lists Winbond ram by manufacturer and so far it appears to be correct.

Thanks Reffa1
So it appears me sticks be of the BH-5 goodness for sure mates!:attn: Allthough 240fsb should have said that loud & clear!
Im so envious. Very nice sticks :D. Keep on OCin Krag!

Reefa_Madness, nice links. I'm going to put that table into my favs. It's only confirming for what many of us know but now whever a n00b says other-wise, we can pull that out to prove them wrong!
krag, many people have done that 3.3V line to 3.6V line mod. It's pretty safe. Make sure you have a fan blowing on your ram or some type of cooling. People have run BH-5 in the 3.6-4.2V range for benching. Winbond themselves rate it up to 3.2V I think.

Sweet! I'm gonna try it as soon as I get some spare time. I have a 80mm fan blowing on the ram now. Thanks for the info bro!

Yeah, but try it with CPC ON!
:cool:
I got some damn good RAM from kingston... hyperX PC3200 non A. Bought at ZipZoomfly a few months ago.
Kind of wishing I dished out the extra cash for 2x512 instead of 2x256. Back then not only was it cheaper, but the 512 megs of RAM is killin' me with Farcry. :eek:
