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

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
