Have a T310 Server with (4) 1GB DDR3 1066 1r sticks. These are the original sticks since purchase.
I have started to get BIOS dropping two of the four sticks with a MAMBIST Failure A2 and MAMBIST Failure A4. Windows 2008 R2 shows 4 GB with 1.99 usable, I decided to move the sticks around to see if I could narrow down the issue, and the problem stayed with the slot. it seems as though my board could be at fault?
