Dell M620 Having Boot Issues

I have a Dell M620 that is having some issues.

BIOS is 2.1.6
IDrac 7 - 1.51.51
LCF - 1.3.0.850
cpld version : 104

When it reboots it first shows this output:

error: memory initialization warning detected.

membist memory test failure dimm a5

after a bit it moves on, and shows the normal:

strike the f1 key to continue, f2 to run the system setup program.

There has been no changes to our system.  Investigating into the drac, i see it recognizing DIMM A5 as present and without issues.

It was reported to me that it said it could not find a boot device, but I have not seen this issue myself, and it seems to boot fine after i hit f1 to move on. 

Please advise.

Thanks,

Denny
