PC Server 325/330 - Some DIMM's missing FRU and option part numbers

Applicable to: World-Wide

The original supply of DIMM's for the 325/330 PC Servers type 8639 model EJ0/ES0/ESV/RS0/PT0/PTW/PB0/RB0 and type 8640 model ES0/ES2/ESS/EM2/PT0/PB0/PM0 are missing FRU and OPTION part numbers on the IBM label. This problem has been fixed in present manufactured stock.

While positive identification of installed memory (using FRU and OPTION part numbers) in a Server is a standard procedure when troubleshooting, the memory can be identified by referencing the "Assembly part number" on the IBM Label (located on the DIMM). Use the chart below to cross reference the Assembly part numbers:

 Assy.p/n          FRU p/n         Option p/n         Size

 -------          -------         ----------         ----

 63H0936          12J4122         94G6474            64MB

 63H0937          76H0656         94G6475           128MB

 63H0938          12J4123         94G7079           256MB

The following diagram identifies the location of the Assembly Part Number (Assy.p/n) on the IBM Label attached to the DIMM.
