Memory Error On Dell PowerEdge 2950 Server

I am getting the following error on my Dell 2950 DRAC log:

Mem Fatal SB CRC: memory sensor, uncorrectable ECC was asserted

Also, I see an amber warning on the bezel and the following message is displayed:

Fatal SB MEM CRC

We purchased an installed new memory modules (32GB) for this machine about 6 months ago and these messages just appeared last month.  How can I troubleshoot the issue to determine:

1.  If there really is a physical memory issue
2.  What modules are the source

This is a production database server, so I'd like to be able to perform the memory diagnostics without shutting the machine down.

The Sensor is generally correct when it say memory errorl.

Here a few thing to try to ensure it correct.
Have you tried changing the memory with another one like switching around the memory and seeing if it goes away.
I would also take the memory out and test in different system with memtest86+

We purchased all new memory modules.  Our memory vendor replaced them as they were defective.  The error indicated a hardware problem while led us to the RMA problem with the vendor.
Unlock the solution to this question.
