I always remove everything I can, go down to 1 proc, the swap procs to see if thats it as well. Only 1 Dimm, and try a couple of different Dimms, but one at a time. If you still get the same voltage error, its dead and there is no fix. #Iwork4dell
I acquired this server about 2 months ago, from a storage unit, showing two error messages:  Error 1 " The system board BP1 5V PG Voltage is outside of range."  Error 2 "The System board failsafe voltage is outside of range" I don't know what's causing this issue, I just know that both power supplies are showing a solid green light, and there is a solid amber light near the iDRAC port. This is a Dell PowerEdge R720. The server boots up for 30-ish seconds and then shuts down and displays these errors, along with the amber light in the back. Because of that, I can't use the server as is. (Unless there is a way to access it while it is in a standby state, its useless right now). It also came with a DESkey DK3 drive. (dunno if its relevant, but I thought I'd add it.) I have looked this error up and looked at a few other discussions and none of their recommendations have done anything. I don't know that much about this, but I can't seem to get into IDRAC, since the server isn't online. Any help is appreciated.
