Poweredge R715 RAM upgrade issues
I work in a Colo center and one of the web servers that we oversee has a RAM mis-match in it. The current setup is 8 2 GB pc3 10600 ECC for the 1st CPU and the other bank has 6 4gb PC3 8500 ECC in that bank. The processor is the AMD 6128, 2.0/2.0, 12MB, Opteron Magney Core. I was wondering how I can stop the RAM mis match screen when the system reboots to be able to remotely reboot the server without having to hit f1 from the console at the server.

Hello jowen34
The memory lanes must be populated identically. If the B lane for CPU 2 does not match the A lane then all of the memory in the B lane will be disabled. Your memory configuration does not match, and that will cause the issue you are having.
If all of the memory is dual rank or lower, and the same buffering type(registered/unregistered) then you can populate the memory like this:
4GB DIMMs in slot A1,A2 - B1,B2
2GB DIMMs in slot A3,A4,A5,A6 - B3,B4,B5,B6
You won't be able to use the other two 4GB DIMMs. If you get two more matching 4GB DIMMs then you can populate it like this:
4GB DIMMs in slot A1,A2,A3,A4 - B1,B2,B3,B4
2GB DIMMs in slot A5,A6,A7,A8 - B5,B6,B7,B8
You can review the memory population rules starting on page 92 of the hardware installation guide:
