List of chips used on DDR2 RAM modules

[Rone]

1GB modules:

A-Data PC2-6400 1024MB CL5 - Remarked Aeneon
A-Data PC2-8000 1024MB Extreme EPP - Micron D9GMH
A-Data PC2-8000 1024MB Extreme Non EPP - Micron D9GKX

Buffalo PC2-6400 1024MB CL5 (D2U800CZ-1GMDJ) - Micron D9GMH

GEIL PC2-5300 1GB (GX22GB5300S) - ProMos
GEIL PC2-6400 1GB (GX21GB6400U) - Elpida

Crucial CT12864AA667 - Elpida 6E / Micron D9DCN / D9GMH
Crucial CT12864AA53E - Samsung ZC05 / Micron D9GCT

Added all of the above. Thanks.

r00n you should make a thread on this type it all out in the post instead of a link and update it once in awile. I am sure that would probably be sticky IMO this is alot better than alot of the stickies now.

One general webpage is more accessible for anyone, anywhere. This is the main reason I started the lists in the first place.
Combined with the fact that the page is already there a sticky offers no advantages.
Post a module that is missing in my lists and it will be up there in no time.

nice little list and VERY easy to read.

Thanks!

Thanks again r00n for your comprehensive, very user friendly lists

Thanks, guys.

Yes much thanx

Do you know if these Buffalo Firestix are D9s also?

http://www.newegg.com/Product/Produc...82E16820150054

I thought they were, but now i'm not sure.

Yes, they are D9GKX (B6-25E). Also added them to the list.

[STEvil]

Comstar (Kingston Value repackaged) PC2-4200 1GB SODIMMS: Hyinx FP-*4

SPD reads as PC-4300

May have been C4, but I didnt write the info down so I forgot that one digit..

[wwwww]

Micron PC4200 ECC also comes with Micron D9DBV - will check the exact Model # when I get home.

First off, nice work with the list.

The above ram might be d9 but it is definately not D9GKX. Newegg claims that the ram they are selling is 4-4-4-12 but the product model number is FSX1066D2C-K1G which is 5-5-5-15. The firestix confirmed to be D9GKX are model number FSX1066D2B-K1G according to this review. http://www.virtual-hideout.net/revie...00/index.shtml

Also in regards to what you said about the corsair memory. Do you mean only the Dominator 8888 memory is D9GKX or does that incluse the Dominator 8500 also?

[WeStSiDePLaYa]

anyone know what chips these are?

from the ocz pc4200 gold xtc.

The product Newegg is selling is FSX800D2C-K2G when I click the aforementioned link.
That P/N indeed has 5-5-5 @ 2.1V, so it could be D9GMH.

The firestix confirmed to be D9GKX are model number FSX1066D2B-K1G according to this review. http://www.virtual-hideout.net/revie...00/index.shtml

I have no idea where you see FSX1066D2B-K1G, but on that page it says FSX800D2B-K2G 4-4-4 @ 2.1V, which have D9GKX.
Newegg's FSX800D2C-K2G are newer than FSX800D2B-K2G.

Also in regards to what you said about the corsair memory. Do you mean only the Dominator 8888 memory is D9GKX or does that incluse the Dominator 8500 also?

I never said Dominator uses D9GKX but yes, all Dominators have the same handpicked ICs.

Good question. Looks like D9GCT to me, the -37 part suggests 266MHz (3,7ns) binned ICs.

@r00n

I posted in corsairs IC thread about my kit of 5400C4's they do DDR2-1000 5-5-5-15. Anyway the repsonse I got was

CM2X512-5400C4 5402V5.7 0628135-2 = Micron-ST, 64Mx8, DDR2-667, CL4, Rev D

I don't see Micron-ST on your micron page. I removed one spreader but it doesn't have the 3 letter code. Any ideas?

Those might be Nanya.
I have checked one pair of those modules and they definitely weren´t Micron.

It is easy to tell what is Micron and what isn´t if you can see the side of the IC.

I don't see Micron-ST on your micron page.

It's still Rev. D so it's simply D9.

Is there anything else on the ICs? Can you post a picture?

Nanya on OCZ? An extremely rare combination.
On the other hand, I have no idea what it could be...

What was on the ICs you took a look at?

Comstar (Kingston Value repackaged) PC2-4200 1GB SODIMMS: Hyinx FP-*4

Hynix only offers Y4 and C4, but since it's DDR533 it must be C4 (Y4 is DDR667).

Micron PC4200 ECC also comes with Micron D9DBV - will check the exact Model # when I get home.

Let me know.

Most important thing visible in this picture is that they are 10x10mm ICs, so it has to be Micron B6.
This means it's either D9GCT, D9GKX or D9GMH.

Always hard to tell on ValueSelect DIMMs. In most cases not even Corsair knows the exact type used.

Thanks, I updated the pic to show sticks before I removed the spreader on one. They are nothing spetacular, but I only paid $89 for 'em and they did DDR2-1000 memtest stable for over 8 hours I've got some 800UL's on the way from newegg

[The Stilt]

I checked them, and they are Aeneon AET93F370.

This is PC2-4200 Gold GX XTC (OCZ5331024ELGEGXT).

Great. Added them to the list.

Thanks for checking.

i got some samsung oem 667 i'll see if my camera will take a close enough shot off. otherwise i'll just write the numbers down.

[marauder16]

What about Corsair PC6400C4 2x1GB, does anyone know if there were D9GMHs are under this baby? I ask because they're not on the list, and I know quite a few of you guys have them somewhere

[Millyons]

Kingston Value ram 667 1gb with relabeled PCS chips, there is pics in the thread i posted in a while ago with model number on the box and stick and how the ICs look

http://www.xtremesystems.org/forums/...2&postcount=46

there are also pics of corsair value that uses those and the chips when they are not relabeled, there also some results


for anyone that is interested in value ram the PCS chips arent bad at all, my 1gb x 2 do about (dual windows memtest) 475mhz 4-4-4-12 with 2.4v and i tested up to 550ish with same voltage and 5-5-5-15......24/7 i run them at 400 4-4-4-12 2v they could probably do 3-4-4-12 at same voltage i just never bothered to test, i also never really tested their max, or their optimal settings......

I also tested Kingston 533 1gb but they werent even close to the 667 ones, might be thoug cause they had 4 different production weeks and few different batch numbers on only 2 sticks so were probably bottom of the barrel sticks

Those PCS chips are also found on (that i know of) Corsair Value, and TakeMS ram (i saw on some forum that TakeMS only uses the PCS chips)


.................................................. .................................................

on Kingston Value 667 i also saw Hynix chips, but dont know the IC markings

and i had Kingston Value 667 2x512 with Elpida 6e chips

ok here is the Samsung 2gb Kit i have

Samsung - 1GB 2Rx8 PC2-5300U-555-12-E3
M378T2953CZ3-CE6
build date of Feb/06

thats what it says on each sticker on each stick.

the ram chips say

SEC 549ZCE6
K4T510830C

they are rated for 667 5-5-5-15 but do 800 4-4-4-12 with 2.0v maybe 2.1 but i dont recall.
the chips dont get nearly as warm as my gskill HZ's at the same speed and voltage. another reason to remove heatspreaders from ram. lol.

i assume since they are samsung ram they are using some crappy samsung IC's

anyone wanna take a stab at this ?

Yep, that is Samsung ZCE6. You won't find anything else but Samsung ICs on their modules.
SEC is an electronics subgroup of Samsung.

Always check the IC Inquiry thread at HoH for Corsair modules.
There are five different PC6400C4 DIMMs listed in their DDR2 section, three of which have Micron D9, two of them Promos.
So unless you know the exact P/N the thread and I can't help you.

You mean PSC, which stands for Powerchip Semiconductor Corp.
Anyway, you've gotten some nice clocks out of them. They're known to overclock like a large brick at 0 Kelvin.
