GA-X58A-UD5 and Corsair XMS3 12GB

Just goes numerically, slots 1-3 are always good, sometimes it goes up to slot 4.

Doesn't matter what sticks are in what slot. I'm thinking this is pointing to a motherboard problem?

Hi...

Probably we may reduce the scope of the problem into the following components:

Memories <==> Memory Slots <==> Signal PCB Traces <==> CPU Socket <==> Memory Controller Embedded in CPU


[-A-] Defective Parts:
[1] Defective memory module(s) - you may confirm this by testing each module one-by-one or two modules each time using Memtest86+
[2] Dodgy memory slot(s) - you may place a single 2GB module to each slot and see if the OS can detect it
[3] Problematic CPU socket (e.g. bent pin(s))

[-B-] Poor Hardware Installation:
[1] Memory modules are not installed properly - you may try to reseat them
[2] CPU is not installed properly - you may try to reseat the CPU

[-C-] Software Related:
[1] BIOS settings - adjust DRAM voltage and timings


You've tried [-B-][1] and [-C-][1]. You may also try the rest and you probably should only try [-B-][2] as last option considering the amount of work. If the problem still can not be solved, I suggest you to RMA the memory kit as well as the motherboard.

Okay.

Thanks for the help guys!

I'll work my way through the list there and give feedback on any changes but i'm guessing this is going to end with an RMA.

Thanks again.

I agree with you too... May be you should consider to RMA the CPU too
