Please, I've got from a friend 3 mem modules, but I don't understand what kind of Dimm are these, coz doesn't fit properly in the standard Dimm slots!

Chip & layout are marked by Hyunday, and there are 3 label with written:

- HYM572A400 ATNG-60 AB
- Hyunday 9716
- IBM 32M 60ns E P/N 20H0681 FRU 19H0289

and on chips there's this code: HY5116400A T-60 9715A (or 9713A) Korea

Thanks in advance for your support ;)

Yes, I'm sure, I've tried on different systems (Simm & Dimm) but the 'hole' in the middle of the module seems to be 1-2mm shifted laterally than the standard Dimm :confused: and onestly it's my first time :)

My mistake, I haven't specified very well :rolleyes:
the PCB is long as a standard Dimm, but the two 'holes', not only one like I said, are just shift of 1mm ;)

Bobt17, I think that we are speaking of special kind of Dimm, supposed to work on a IBM RS/6000, and Yes, they are coming from an old Computer, but no info are available from this friend of mine ;)

I think the holes/grooves are for different voltages and ECC for RAM if my memory is correct.
Yes, probably you are right FireMogle ;)
Please, no one of the Guys & Gals present on the Forum are experienced in IBM Risc HardWare?

Still many thanks for your support ;)
