Cant identify IC

[D-Rock]

Hey guys, I finally puled the heat spreaders off my old set of OCZ SLI-PC2-6400 1gb sticks and read the IC numbers. I cant identify what these things are to save my life. All I know is that the ICs were originally made by powerchip because the last character sequence on the IC is L93G. If anyone can help me find info on this particular IC please let me know. There is no definitve need for this information other than for my personal benefit and I plan to contact a few websites and let them know about these ICs and how they perform (stock and clocked.)

The pic below shows how the IC looks.

Try asking the guys on the OCZ support forum. They might be able to help.

Thanks, I will be posting a new thread there in a few minutes. Just have to wait for the activation email in my inbox.

Pro-Mos.

Umm what?

Can you tell me how you know this?

[reverandmaynard]

Is just telling you what it is good enough? lol.

[D-Rock]

Well no not really. Forum senior or not, I dont just take peoples word on things. No offense but to me its like buying a used motherboard without testing it myself. Im not just going to take someones word for it.

Please tell me how you identified this chip. I really want to know the IC make and model. Not just the make.

Additional Comment:

Well ocz support forum verified it as a powerchip but they are still digging up more info. Its a bit hard for even them. OCZ seems to be very finicky on what IC they employ on their RAM, apparently it changes all the time.

[reverandmaynard]

I say ProMos because that little round indentation at the lower left corner is indicative of the thousands of ProMos made ram that I have sitting in trays of 100 at work. Nothing to do with being a senior member. Looking at http://ramlist.infinityx.nl/ddr2/ helps as well. If what you have is the SLI version then it'll be the same chips thats in the Reaper and FlexX.

EDIT: I posted over at XS for ya. We'll see what Tony says.

[D-Rock]

My opinion now is set on neither one nor the other. I see what you mean about the indicator in the lower corner. I also see what you mean about them being the same as the reapers and flexx. Here is exactly what I was told on a PM over at the ocz forums.

OCZ might not give you the chip information... but here it is...(and I can't post on your thread)

For OCZ's part number (from what I can tell so far)...

X43P120840L-25H

PSC (Powerchip Semicondutor) 64x8 Rev. H Sorted at 6400 (-25)

Can't tell from the part number if its an original 800 or 667 chip...

I am waiting on another response from him as well. I also sent an information request to OCZ tech support, but I doubt they are going to be helpful at all. I requested info from them about these specific modules a while back and they gave me bupkis. I didnt mean to insult your intelligence reverandmaynard but I never just take anyones word for anything. If someone tells me something I want to know how they know.

[reverandmaynard]

No insult taken. You have every right to question information given by some random on a tech site.

[D-Rock]

The only problem I see with the PM i got on the OCZ support site is that he said its a density of 64mb x 8. But these are 1gb sticks, and the density is supposed to be 128mb x 8.

64mb x 8 is for a 512mb stick.

so im unsure what to think.

Additional Comment:

Oh well, I just realized that these are double sided sticks with 8 IC per side. Im a dummy.

On the bright side though, these have been confirmed that they are powerchip revision h die, sorted at 6400 and are 64mb density.

Additional Comment:

Maybe this will help some of you other guys with OCZ RAM.

Hey D-Rock,

The part number indicates that they are 64x8, and plus there is no H-die (also on the part number) for any 128x8 chip, including PSC....

If they are 128x8, then they were mismarked by OCZ....

I know most memory company's markings (I work very close to the industry )... as they try to hide their part number so others do not know what chips they are using. In turn, they can change to a cheaper chip if it qualifies at the same speed, and then only change one or two letters on their chips to help themselves recognize what they were using at a particular time....

For OCZ, here are the main components of their part number (until they change it)...

Examples:
8500 128x8
OCZ X42E1288I-187C
The E stands for Elpida, 1288 stands for 128x8, 187 stands for 8500 sort, C stands for Rev. C

6400 64x8
OCZ X43P120840L-25H
The P stands for PSC, 1208 stands for 64x8, 25 stands for 6400 sort, H stands for Rev. H

BTW... You cant tell from the marking if the chips were originally 533, 667, or 800MHz... only what they sorted them at. I say the 6400 64x8 chips were likely 667MHz originally, but they got them to sort at 6400.

seems too me that OCZ don't know their arse from a hole in the ground.

?

They correctly identified it as Powerchips, not ProMOS like you thought.

Ask RamGuy to ID the ICs on a set of Corsair value ram. Same thing when a company sticks their name on someone else's chips.

[Whoareyou]

LOL, browsing these forums and I see that the IC problem has been solved...

BTW... Corsair knows exactly what they use on their value ram.
