Processor Problems

NOTE
If a problem exists with the HP Server processor;
1. Remove and reseat the processor module(s).
2. Remove and reseat the CPU Power Pod(s).
3. Check the System Event Log (SEL) for any processor errors.
4. Check the System Event Log (SEL) for any CPU board errors.
5. Run Platform Diagnostics to test the processors.
6. Replace each of these components, one-at-a-time, with a known-good component, and retest
the HP Server:
Processor
◊ ◊ ◊ ◊
CPU Power Pod
◊ ◊ ◊ ◊
Y-Cable
◊ ◊ ◊ ◊
CAUTION
3. If the fault persists, replace the CPU board.

Memory Problems

The memory modules are DIMMs.
NOTE
1. Review the Troubleshooting Checklist before you continue.
2. If memory problems are being experienced, power the HP Server off and on. This performs a
"cold" restart, rather than a "warm" restart (as it does when you press Ctrl+Alt+Del).
Check the System Event Log (available on certain HP Server models) for messages indicating
memory errors.
4. Check the status of the memory modules through Intel Server Control (ISC), if applicable.
5. Run the Platform Diagnostic test.
6. Reseat the memory modules.
7. To check that the modules are installed and configured correctly:
a. Remove all of the installed memory.
b. Install one set of known good DIMMs (4 in a row). If you still receive an error, replace the
memory board.
If the error goes away, add another set of DIMMs (4 in a row) and reboot again. Continue
this process until you have installed all DIMMs or you experience a failure.
Bad processors are mapped out by the BIOS and are not tested again at power-up
of the server. To retest a processor, enable Processor Retest through the BIOS
Setup Utility.
Do not push on the processor components; push only on the edge. Pushing on the
device may damage it.
If the POST (displayed at power-on time) indicates a defective memory module,
replace it.
