I have 6 R710s that all have the exact same hardware configuration. 2 Power supplies, 2 CPU, 12 DIMMS no HDs. One of them had a DIMM unseat and showed an error. I re-seated the DIMM and the problem went away. Now, at bootup that one server says that the power supplys are insufficient to power the system and that it will run at minimum speed. I've tried many things to get it running normal again, upgraded the bios, firmware etc. Checked the power supplies, but still can't get this one running at full speed. If I pull 6 of the DIMMS it will run at full speed.
All the research I have done points to the power supplies not having enough power. The strange thing is, that it has been running that way for 3 years, and I have 5 others that have that exact same config and they work fine. Any one have any ideas?
