Is my RAM 128 or 256Mb??

  kelemvor 16:59 11 Apr 07


I'm looking to sell some RAM that I pulled out of a non-working PC that I had, but I'm not quite sure if it's 128 or 256 Mb. I have done a search on the web using the 'serial' code on the chips, but I have found conflicting answers.

The ram is pc133 (168 pin) by infineon and the code is - hyb3912800ct-7.5

can anyone tell me what size memory this is??

what make and model of pc is it?

  kelemvor 17:09 11 Apr 07

It 'used to be' an advent pc (bought from dixons) a few years back. 1gig athlon chip - can't recall the motherboard make sorry.

I've just noticed that on the line after the serial code it says C2 (I think this may be part of the serial code)

Are there any other markings on any of the chips. I was hoping we could work out if the motherboard supported a maximum chip size and that help identify them.

  kelemvor 17:30 11 Apr 07

Ok, the max for the motherboard as I recall was 1 gig - I recall upgrading to that size, but can't recall what size I upgraded from. It was a while ago after all.

The only markings are:
1 - the info that I posted above
2 - name infineon
3 - Each chip has one of these on it - EEE 26288, EEE 26094, EEE 28013, EEE 26182, EEE 26236
4 - the edge of eah chip has: 0214 on it
5 - the Ram stick has: 7F8RG on one end
6 - the bck of the stick has 94V-0 on it

and there are 8 chips in total on the stick.

Do you have a family member neighbour or friend who you could borrow their PC to find out the specifications. I can find no information on this ram stick.

I believe the sticks are indeed 128MB.

  kelemvor 17:49 11 Apr 07

I don't sorry.

Skidzy, how sure are you??

I have gone through a couple of sites and some say 128 and others say 256 - they both seem to have the same serial code.

Maybe just as a guess that the 128 in the hyb3912800ct-7.5 is refering to the size.

  skidzy 17:56 11 Apr 07

I cannot find a definate answer for you,but from experience in changing ram,some if not most have the value MB listed within the serial code,hence your post hyb39(128)00ct-7.5.

I may be wrong as not all ram have this,but some older ram does...especially Emachines bought from Dixons/PCW etc.

Im afraid i cannot prove this to you,the best way is to install the ram in a working pc and hope the ram is compatible and run Belarc or Everesthome.

If you can get another 9 you might be able to get a £5er for them.

I'm afraid that these days most folk are looking foe 512MB or even 1GB sticks and rather faster than that which you have.
