PERC 2/QC - Source for Cache Memory?

Question

Does anyone know of a source for obtaining the 128 MB 50ns unregistered EDO SDRAM memory required for the Adaptec PERC2/QC RAID controller card? I've got a couple of these cards with smaller cache modules that I would like to upgrade, but it seems Crucial and most of the other memory suppliers have dropped this particular memory module from their line.

You could try contacting Dell Spare Parts at 1-800-372-3355. The part number for the PERC2 128MB DIMM is 1479D.

Thanks for clearing that up

MT18LD1672G-5X is Buffered memory, used in older servers, such as PE6300/6350. This will not work in an Perc2/qc.   MT18LD1672AG-5X is Unbuffered Memory, used in workstations & PC's.   MT18LD1672AG-5X (or equivalent) is required for Perc2/qc cache.  [Unbuffered 50ns EDO memory]. Note that 60ns will not work either.
