T7910 - bad dimm socket

Hi all,

I have a T7910 in mint condition with the exclusion of the DIMM2_CPU2 socket which is damaged. The dimm population order effectively cripples this machine. If I want full speed memory I can at most only use four dimms.

Is there any solution to this problem other than full mobo replacement? I find myself wishing there was a UEFI option to reverse the memory population order from "white" to "black".

Thanks!
