PowerEdge R520...VLT0304 CPU 2 MEM VTT PG Voltage is outside range

Can someone please point me to the right direction.  I just upgraded my PowerEdge R520 Memory from 32G to 96GB using Six 16GB DIMMs (2Ranks with Speed 1600 MT/s).  Everything works great all day yesterday but when I came in this morning server box was down and reported the errors below:

error1: System board fail-safe voltage is outside of range.  Contact support

error2: VLT0304 CPU 2 MEM VTT PG Voltage is outside range. Reseat CPU.

So far I have done the following and no luck:

1) Disconnected AC power from box for 2 minutes.  Re-applied the input AC power and turn system on (did not work)

2) Reseated the CPU 2 (did not work)

Note:  I upgraded two machines.  The other box is still running without any issues (RAM Part #: SNP20D6FC/16G)

Please help

Thanks

Can you get into the bios? Is the ram the se speed and voltage of the old ram?

I would first upgrade all firmwares if not already done.

If you can get into the bios, make sure all the ram settings are auto. Resetting the bios to defaults is even better.

Guys,

The RAMs are the same speed and same Rank.  I have a couple more new R520s so I added the same RAM and left it running for 3 days and nothing has happen.  Looks like a possible motherboard failure.

Thanks
