Servers - PC Server 704, 330, 325, 315 may trap, hang or reboot
Applicable to: World-Wide
SYMPTOM:
The PC Server intermittently traps, hangs, or reboots.
PROBLEM ISOLATION AIDS:
This failure has only been observed in a controlled lab environment under stress tests with elevated temperatures.
One or more of the following SIMMs/DIMMs are installed:
PC Server 704:
64MB SIMM FRU p/n75H9125 (Option p/n94G5879)
128MB SIMM FRU p/n76H4896 (Option p/n94G6682)
PC Server 325/330:
64MB DIMM FRU p/n12J4122 (Option p/n94G6474)
128MB DIMM FRU p/n76H0656 (Option p/n94G6475)
PC Server 315:
64MB DIMM FRU p/n42H2802 (Option p/n76H0280)
128MB DIMM FRU p/n42H2803 (Option p/n76H0281)
FIX:
Use the following procedure to identify suspect SIMMs / DIMMs:
1. Inspect the SIMMs / DIMMs for the presence of SEC DRAM modules:
x can be "V" for the 3.3v part or "C" for the 5v part.
y can be "0" for FPM part or "4" for EDO part.
2. If any SEC DRAM module on the SIMM / DIMM has KM44x1610yAK-6 AND a date code (###) less than 710, replace the suspect SIMMs / DIMMs using the FRU part numbers from above.
3. If SEC DRAM modules on the SIMM / DIMM have KM44x1610yAK-6 and date codes (###) of 710 and greater, then no action is necessary.
4. Other SEC DRAM modules regardless of date code are not suspect. It is highly unlikely that systems running in a normal operating environment would experience this memory symptom. This symptom has only been observed in a high temperature, stress-test environment.
If the Server is not experiencing these exact symptoms, then there is no reason to replace the SEC memory even if suspect
DRAM modules are found. Continue normal problem determination procedures to isolate the failing application or FRU.
FRU and Option stock have been cleared.
