IBM PS/2/Servers - System failures with 16MB ECC memory installed
Applicable to: World-Wide
Symptom:
A limited number of 16MB memory SIMMs could cause NMI errors in a multitasking application environment such as OS/2, AIX, Novell Netware and Windows. (NMI errors are reported as Trap 0002 by OS/2. Other operating systems may refer them as "PANIC" errors.)
Problem Isolation Aids:
The affected systems are:
1. 9595-xNx, xPx and xQx
2. Any 8595, 9595 systems upgraded with either:
a. A 486DX/2-66Mhz processor card, option part number 32G3961, FRU P/N 61G2343.
b. A Pentium 60 MHz processor card FRU P/N 52G9362
c. A Pentium 66 MHz processor card FRU P/N 92F0120
3. 9577-VTG. (Note: Other 9576/77i 9576/77s models xUx, xNx, or xTx that contain this SIMM are also affected.
Refer to the diagram below to determine if a given SIMM in the system might exhibit the problem.
Note:
All of the following conditions must apply for this tip to be applicable.
1. The system is exhibiting the failure symptoms.
2. The memory installed is IBM 16MB ECC 70ns, FRU P/N 96F9100, Option 92G7209,
3. It must be assembly P/N 42G3237.
4. The raw card part number must be 32G8299-01. This number is located on the back side, above the notch of the card.
5. A product code 'UVAC' on the small white identification label on top one of the modules.

Fix:
If NMI error symptoms are being experienced, only the memory SIMMs which meet the criteria described above should be replaced. If none of the SIMMs meet the description, normal problem resolution procedures should be performed.
