I've recently attempted to upgrade a Dell PowerEdge 815 with more RAM and a 3rd/4th Processor.
The original (working) configuration was:
- 2 X AMD Opteron 6220 (8-core) Processors
- 16 X 2GB RDIMMs
Attempted update:
- (Added) 2 X AMD Opteron 6220 (8-core) Processors and Heatsinks
- (All New) 32 X 4GB RDIMMs
After the upgrade the unit does not produce video output, the front-panel LCD report "System Rebooting...". There are not POST error audible tones, the drives appear to spin-up as usual, and no apparent network connectivity.
I've tried various trouble shooting steps:
- 4 Processors/32 RDIMMs (Result: no video, no network connectivity)
- 2 Original Processors/16 New DIMMs (Result: Works like before)
- 2 New Processors/16 New DIMMs (Result: Works like before)
This tells me the new processors are fine, and the new RAM is fine. I'm otherwise stumped. I've done all the appropriate googling, with no luck.
Any suggestions?
