List of chips used on DDR2 RAM modules

[Desert Igel]

afaik they still have D9GMH

[Rone]

Can anybody confirm that Ballistix Tracer 667 are D9GMH now?

Yes, they are.

[Don_Dan]

I don't know if you saw it, but in the thread about the OCZ PC2-6400 Flex XLC CAS 3 Andy from OCZ confirmed that the chips used on the modules are Elpida. Maybe you can add them.

I've The discontinue Dominator 6400C4D but this revision 1.2 in ramlist tis IC's is D9GMH Handpicked,
i can run 1000 4-4-4-4, 1066 4-4-4-4 on 2.25v and 2.3v in max cas 4 it's kick only 540 @2.45v

is it these stick good or not for standard D9GMH perfomance?

Yes, I noticed. I talked to Andy and he confirmed it's Elpida.
The thing is, these chips do in no way look like Elpida. I refuse to believe it until I find some 100% unmistakeable proof.

And how do they perform with CAS 5?

Max Cas 5 an d Stable @1160 5-5-5-15 2.3v, i try hit 1200 5-5-5-15 on 2.4v but orthos i found error

Are OCZ PC2-8000 XTC Platinums still using D9? Seems like Apacer is using ProMOS for PC2-8500.... I didn't think ProMOS was capable of those speeds?

[Desert Igel]

afaik OCZ uses only D9 on all memory at PC2-8000 and above

Yes, they should be.

Seems like Apacer is using ProMOS for PC2-8500.... I didn't think ProMOS was capable of those speeds?

It's possible given the right circumstances and IC quality. Higher latencies and a boost in Vdimm, et cetera.

afaik OCZ uses only D9 on all memory at PC2-8000 and above

That is correct.

Was already told, that Mushkin isn't using D9GMH anymore on the HP2-6400 Modules?

In Germany some guys got Promos. I think my HP have also Promos.

And here a thread of the Mushkin-forum.

I've edited the list accordingly.

Thanks for notifying me.

Last week I' bought 2x1 GB Kit ADATA 800+ extreme sticks packed in black plastic package, on my P-35 DS3 mobo i can run at 960 5-4-4-10, but problem is that its not stable at CAS 4 at 2.1 V increasing voltage not help, I try 2.4, is that BIOS issue or stick does'nt contain Micron chips?

[Desert Igel]

They use D9GMH, unlabeled Micron and AFAIK Promos.

*revives thread*
I have a question about the Micron ICs, being that on your website (@ r00n) you stated that the Micron D9 ICs are 10x10mm (1x1cm). I have a set of Mushkin SP2-6400's (the newer revision though, not yet listen on your website), which has 1x1cm ICs, as well as the set of A-Data Value DDR2-800 CL5 that I have here. I am rather new to DDR2 RAM overclocking, and I am able to run 4-3-3-8 on the A-Data's @ 2.35Vdimm. Are those Microns? I'll get pics up in a second

[Edit] Sorry for the shoddy picture quality
The Mushkins:


The A-Datas (running in my system):

PC2-8500 HyperX
KHX8500D2K2/1G
KHX8500D2K2/2G
5.0-5-5-15 @ 2.2V

Micron D9GKX (B6-25E)

is this correct? got from DDR2 RAM list.
i got a 2GB kit of these and they are very nice.
still dont know the max of my kit, but 1100 at least at CAS5 with 2,1V (AM2 x2 4000+ at 2750vcore default)

No, in case of Micron only B6-x ICs are 10x10mm (D9GMH, D9GKX, etc.). For more information check my Micron DDR2 IC Info page.

I can tell you the ICs on the picture of the A-Data memory are definitely not Micron (they look very much like ProMOS), but the picture of the Kingston module is way too blurry.
If it has the same kind of ICs as the A-Data they too are not Micron. You could compare them to the photos on my Various DDR ICs page.

It had D9GKX when I added the kit to my list, but you can't exclude the possibility that Kingston switched to a different kind of chips.
On the other hand I can't think of a reason to use anything else than Micron for a PC2-8500 product.

thx r00n,,
first of all congratz for the ram lists. i've looked at them lots of times and its very useful for me and lots of people.
i´m reading some posts where in some 8500 kits of other brands they are using Promos, so maybe kingston did the same. also i heared about DDR2 new ICs that nedd 1,8V for 1066Mhz
i think my kit is D9 for sure, maybe GKX or GMH, i dont really mind, im very happy with them. now running 1000MHz 5-4-4-12 at 2,0V, maybe they need less voltage or i can tighten timmings. this is for 24/7

[mad_skills]

Team's DDR2 1200modules use GMH or GKX chips?

[Saturas]

I've a question, in the list the Buffalo Select Sereis is marked with Micron D9 chips, is this still fact?

And then, here in germany I can find only Buffalo Select Series with this serials:
D2U800C-1G/BJ
D2U800C-1GA
but in the list it's
D2U800CZ-1GMDJ

Hmm, how is the chance to get D9 on these ?

What do You think, what IC's is this:

I think it's D9HNL? Dimensions are 8x12mm, memory is Crucial Rendition 2Gb 667 (RM25664AA667.16FE).

[Don_Dan]

Hey R00n!

Maybe you can help us and identify the chips used on this Crucial Ballistix 8500 kit: http://www.xtremesystems.org/forums/...d.php?t=176432

You got a PM btw...

If the dimensions are indeed 8x12mm then it can't be D9HNL, because those are 8x11.5mm.

8x12mm means it's a BP-chip, so it's a relatively old Micron IC (ie. D9CHJ, D9CHL, D9CHM, D9CZM, D9DPN, D9DPQ, etc.).

Thanks, I posted a message in the thread you mentioned.

@ r00n - I've been reading your DDR2 List webpage, and have a question - why are some Micron chips red or green or black? what do those designations mean?

I'm looking for new RAM, and those answers will certainly help in my decision making. thanks

[Don_Dan]

I will try to answer the question on behalf of Ronald.
The red ICs are of the older Micron chips family, the good ones were referred to as fatbodies, but those are now discontinued.
The black ICs are the chips that are not of special interest for us overclockers because they don't clock extraordinary.
Finally, the green ones are the chips you should look for, because these are very good for overclocking as they scale well with the applied voltage.

If you're looking for some 24/7 RAM, you should also take into consideration the 2x2GB kits using Powerchip that were announced lately. Just have a look in the RAM section!
