Web Server crashing due to memory errors. It's like clock work

I have an IIS server that is crashing at about 3:15 am every Friday and Saturday. I understand that swapping out DIMM A in Bank 1 would probably fix the issue. But I would like to hopefully resolve the issue before we do that. But replacement RAM is scheduled.

Below is a jist of what happens.

Any ideas are greatly appreciated.

Replacing DIMM A in Back 1 was the resolution to this issue. I was also able to reproduce the issue on a separate server using the same DIMM in question.
