Is it possible to tell the difference between a brain power PCB and a JEDEC reference PDB by looking at the RAM stick (without heatspreader). Because you can tell the RAM chips (obviously) but it would be good if there is a reliable way to tell what the PCB is too.
Hey Punisher, I've asked Transcend and they've confirmed they use both Samsung UCCC and TCCC for their PC3200 1gb Samsung line.
Also, the info on Corsair value RAM 1gb appears incorrect. According to Corsair, their Value Select line is procured at the wafer level and packaged by Corsair http://www.houseofhelp.com/forums/sh...ad.php?t=44365
Therefore, saying they are Micron 5B-D or Samsung UCCC or whatever seems incorrect.
anyone have details on the 2x2GB kits coming out from Geil ?
They're due in Australia in two weeks time
LOL... man you have to distinguish between memory producer and memory ditributor:Quote:

Anyway for Trascend 1GB I think re-voodo will add TCCC too soon.
For error reporting (dealing with 1GB stick listing) please use: cavodamage@tin.it
I know there are some errors but your Puni doesn't matter anything ;) :D.
I can confirm CTP-D43 are found on 1Gb sticks. Saw them a few days ago.Quote:

I dont know if this has been reported but Transcend based UCCC can churn out some insane nos.

This isnt stable but benchable.I say good enough for Transcend,isnt it ?
Someone have info about the chip used on the Corsair TwinX2048-4400CL3 Pro, i have heard Infineon.. Hynix. i know the 2048-4000PT seems use UCCC, but for the 4400 i don't know..
I think you misunderstand me. I know the difference. I think I misunderstood what Corsair were saying but I think you misunderstood what I was sayingQuote:

My understanding is if the chip is marked Samsung, then it means it has been packaged and tested by Samsung. They will be unmarked or perhaps marked with the Corsair brand or some other brand which Corsair uses to mark their memory chips if they are purchased at the wafer level and not tested and/or packaged by Samsung. However I believe I was incorrect, this is not what they were saying
My understanding now is that what Corsair is saying is they do not buy the RAM as chips and then put the chips on to modules. Instead, they tell someone what they want and the specifications they want. This could be Samsung or whoever. Samsung then packages and tests the chips, puts them onto modules and tests these and label the memory module. As these memory chips are tested and packaged by Samsung, they are marked as Samsung (or whatever). However because Corsair does not source the chips but instead the modules, they cannot use revisions etc to differentiante between modules with different chips.
N.B. In practice, when I say Corsair/whatever does something, I of course mean someone operating for Corsair/whatever.
In any case, Corsair modules can also come with Nanya chips, see this link http://www.3dgameman.com/forums/showthread.php?t=42752
P.S. When I say memory chip, I mean memory/RAM IC. It's the same thing. I refer to the memory module as memory/RAM module or memory/RAM stick
Lane, have you tried asking at the houseofhelp
http://www.houseofhelp.com/forums/sh...ad.php?t=44365
where are OCZ's PC-4000 Platinum 2x1gb / 2x512mb? I don't see those.
@Punisher
I've got some info on some RAM modules that R not on the list
like
OCZ PC3200EL Titanium Edition should be Infineon CE-5
PC4000 Platinum Edition XTC - Micron -5B F
Patriot
Signature line
PC3200 (PSD2G400K) - have some info that could be Hynix on and some say Infineon CE-6 (if U can check that)
Extreme Performance line
LL
PC3500LL (PDC2G3500LLK) - Infineon CE-5 + Brainpower PCB
EL
PC3200EL (PDC2G3200ELK) - Samsung UCCC + Brainpower PCB
SuperTalent
PC3200 C3 - Samsung UCCC

Hey Guys,
About a year ago I traded my PQI Turbo Platinum DPU (2 x 512mb) modules to a friend for his GEIL Ultra X (2 x 256mb) engineering samples (was told it was BH-5 but don't think so). Ever since I actually got the RAM I've been trying to find info on them with no luck.
Well the other day I found this article from Anandtech on the GEIL Ultra X (2 x 256mb) modules. At first I was excited because I thought I found it. After pulling the heatspreaders off my modules I realized they were very close but a couple of the numbers don't match. Plus if you look at the picture I took of the IC's on my modules you'll notice that mine have the two dimples that UTT modules have unlike the ones in the article which don't have any dimples. The only info I have been told is that their "engineering samples" and from looking at the IC it looks like their 3.5ns chips?
I wanted to post here becuase out of all the forums I frequent you guys know the most about higher voltage memory! Plus since I've been unsure about what these modules actually are for so long I really want to know so I can use them to their full potential! If anyone has any info about this RAM please fill me in. Then I can start testing them and see what their capable of! Thanks guys for you help and time.

I'd say they are winbond based chips. They have 2 round spots, 2 metal "strips" on the side from the chip and the little pin1 marker spot. Not 100% sure. Can't tell you what kind of winbond they are.
Thanks for the reply Comp-Freak, much apprecaited! I've learned a bit more since that post. I talked to the original owner and he said that although they have almost the same writting on them as the regular Ultra X kits these are indeed a special one-off kit with what he swears are BH-5 IC's. From what you said about the actual chips I'm starting to think they might actuall be just that?
Being an engineering sample that he got from GEIL from someone he knows they might have just printed those numbers on it even though they might actually be 5ns chips? Who knows, but thanks again for your help. Hopefully more people will chime in with their thoughts and opinions!
GeiL relabeled some of those Winbond chips. Scrape off a layer of silicon and you can find out! Probably kill the mem though. ;) That's how it was initially proven. I believe they were all BH-5 though.
Ok.. after my Inquiry to Corsair about the chip on TwinX2048-4400C3, i have just this info :
- TWINX2048-4400PRO XMS4401 v1.1 0614288-7 = INFINEON, 64MX8, CL 3, Die Rev C
- CMX1024-4400PRO XMS4401v1.1 0608065-1 = INFINEON, 64MX8, CL 3, Die Rev C
someone have more precision?
( Edit: - i think have read on front page the Corsair XMS i m talking about is marked like Samsung UCC, a little add to do?
the link to Corsair Inquiry thread with the chip on the Kits..:
http://www.houseofhelp.com/forums/sh...ad.php?t=44365 )
I'm looking to get more RAM to OC my system, I'm OCing it by 200Mhz now but that's as far as it will go with the Current RAM. Any suggestions?
Now, I've been talking to Lane-k about this but what does everyone else think about it?
Lane, not that I don't trust or value your opinion, but 2 heads are better than one.
P.S. Thanks for the help Lane, wouldn't be postin w/o you.
Can anyone point me to that article from DFI forums where they got all those bunch of timings layed down and explained in detail to as what each does
What does this mean for me... I have XMS-PC4000-TWINX2048-4000PT ... and this says Samsung UCCC + Brainpower PCB. Does this in reality mean that the chips on mine are mixed up in some sort of way? Would be very happy for an answer since it seems mine don't go over 500mhz without rebooting and such *c*r*a*p*... or failing memtest86 over 500mhz.Quote:

The reason for asking is that I have (as you see below) seriously overclocked my cpu, but my ram should be somewhere in the reading of 500mhz, but since i can't get them over 500 i have to drive them at 466mhz, that's really boring... have tried 1T and 2T, but there is no difference at all in the clocking, so i put them on 3-4-4-10 1T to be able to make it steady and I don't think it's that good at all since i can't get them over stock mhz.... HEEEELP!!!! :eek: :eek: :eek:
I found out on http://www.houseofhelp.com/forums/sh...ad.php?t=44365
TWINX2048-4000PT XMS4000 v1.1 0540080-1 = Samsung -5 Rev C 64M X 8
or
TWINX2048-4000PT XMS4000 v1.1 0602105-1 = Samsung 64m X 8 Rev C
or
TWINX2048-4000PT XMS4000 V1.1 0608017-2 = Samsung -5 Rev C 64M X 8
Which of these are any good? Is it dangerous to remove the heatsinks attached to them to see whic numbers are on mine, could I destroy the chips?
I'm really happy for any replies.
somebody find out what kind of IC's the Patriot 2x512mb LLK kit uses. im dying to find out, but nobody has it and reviews for the stuff are hard to come by.
I'm sitting here with some Kingston HyperX PC 3200ULK2/1G, and then I find this at the ram list:
So I wonder, are my ram TCCD? or could it be some other chips? - I do not have a possibility to test these at the time...Quote:
HyperX PC 3200ULK2 (2-2-2-5-1T) (KHX 3200ULK2) --chip--> Samsung TCCD
Can anyone identify the chips on the 2x512mb kit Corsair PC-3200 C2PT? I am unsure of the revision, I'm asking for a friend, and he can't tell the rev. Timings are also unsure but likely 2-3-2-6 1T
Thnx
-Satan
3200C2 timings are 2-3-3-6-1T.Quote:

Yeah, but remember, he can't tell the revision. Also C2PT is different from C2.
-Satan
Without that info, it's impossible to tell (without ripping off the heat spreaders and voiding the warranty) what ICs they use.Quote:

i've red a lot of the forum and i've got tired.
Pls i have
Corsair TWINX1024-3200C2 2xCMX512-3200C2 XMS3202V5.2, 0634191-0
I found this on the net
TWINX1024-3200C2 XMS3202 V.5.2 0541017-0 = Promos -5 Rev A
CMX512-3200C2 XMS3202v5.2 0540107-0 = PROMOS 32Mx8 0.12u ETT
CMX512-3200C2 XMS3202v5.2 0607346-1 = PROMOS 32Mx8 0.12u ETT
What does these mean? Whith what kind of chips are they? How well do they clock? And How!!!
PLS Help me?
PS: Sorry for my english :)
You'd need to post in the thread I mentioned earlier to get a concrete answer as to what IC your memory has.
:toast: good job on the list and updates.
just for confirmation the A-Data pc 3200 1 gig sticks are Samsung UCCC?
Doh,Never mind!yeah I must have been a little tired and did'nt read the entire list through,ended rmaing the Adata.
lol the title needs to be updated or something. I got all excited haha
Add also 2x1GB Transcend PC3200 with Micron 5B-D ~ Brainpower PCB that i have found lately
Just came across an old corsair value select PC3200 512mb stick thats now doing 500 MHz @ 2.7v orthos stable. Code on the IC's is 64M8BDCG & under that is PRB0900622. They have a small circle dent in the lower right hand corner.
Has the letters 'BP' in the middle on the back of the stick.
Any idea what IC's they are?
