How do I read a RAM stick?

How do I read a RAM stick?

How do I read a RAM stick?

I've got several RAM sticks which I pulled out of an old PC which I'd like to use for a newer PC or two, but I can't make heads nor tails of any of the numbers on them.  I'm trying to figure out how much memory each stick has (the old PC had a hard drive crash and I don't have any details on the hardware except what I can read off the actual pieces).

Does anyone know of a website which lists what the numbers on the sticks mean?  On the green plastic, HJ M1 94V-0 is stamped.  On the black "boxes", there are several numbers. Like: TI - 60, TMS417409DJ, AC 82 Y1041, etc..

The last set of numbers vary per stick, so I'm assuming these are serial numbers???  OC 82 Y02JI or OC 81 A3821 or AC 82 Y1041 are the other last numbers...

Any and all help would be appreciated.  Thanks!!!

RE: How do I read a RAM stick?

Here's your best bet, get your new pc up and ready, and drop them in, one at a time.  Windows will detect the size of the ram, and you can go from there.  Or if you have a friend that has a pc that you could borrow for a few minutes to test the sizes of the ram, you'd be in great shape.


RE: How do I read a RAM stick?

not all ram states its size and speed, so it wont flat out sa pc 100 128 mb, it will have a bunch of crap you dont understand, (i dont either) so the post by jeff is exactly what you have to do, just make sure yo dont throw some away because it doenst work, because if it is a different speed some mobos dont drop it down and it wont detect, so try to test it by itself if possible, or in a few differnet machines, if of course it doenst work on your first try

RE: How do I read a RAM stick?

right, if it's pc 100 128 meg of ram, it's not going to be detected in a machine that only can read 66.  


RE: How do I read a RAM stick?

perhaps it would help to know more about the machines you pulled them from...  if you identify the box or mobo, you'll be able to narrow down what was possible at least, especially in terms of speed.  Based on that, you'll know what to test them in to get how big they are.

The TMS417409DJ is a 60ns, 16MB in 4MB x 4 bit EDO RAM.  The 'black boxes' are the RAM chips, printed with model numbers.

Now, how many do you have on the SIMM?  The HJ M1 94V-0 seems to be a 32MB SIMM, so 2?  If only 2 (or any even number) then no parity.

60ns EDO was a very common RAM format for high-speed (then) Pentium I's / Socket 7 CPU's.

SIMM's get used in pairs ONLY.  Incompatible with PII, P3 or P4 / Athlon architectures.

Your mileage may vary...
