Unfortunately they have had no effect, so I’m looking for some suggestions, I do however have a feeling that the motherboard could be faulty.

I am also encountering the problem with the CPU temperature reporting only sometimes working.

Problem
Bios and windows only seeing 2GB of the 3GB of memory.
CPU-Z sees all 3 sticks of memory.
System installed without problem and runs fine even though some memory is not detected
Each memory stick passes memtest OK individually

i haven't encountered this before, i've tried to flash to the latest 1005 bios, but it seems not working too..

any idea..?
In CPU-Z under the memory tab, which # Slots (out of the 6) are occupied by memory?

I have had this issue of memory detection and it was simply a problem with the way the CPU was seated. The first time I ever put together my R3E rig it fired up perfectly with 6GB ram. I switched coolers and for some reason decided to pull out my 920...D'OH! After putting it back in and turning system on Bios detected a new CPU was installed, and bam only 4088MB showing. I noticed though that in CPU-Z when you're having memory detection problems it shows the memory installed in the first three slots (#1, #2, #3) instead of #1, #3, #5 (for 6GB). As soon as this happened I had a strong feeling it was an improperly seated CPU. Just after finishing putting it all together perfectly (I'm a perfectionist) I had to pull off the cooler again to re-seat the CPU. But afterward all 6136MB were being detected and never had that issue reoccur.

I think you're best bet is to re-seat the CPU. I know, it's a but what are you gonna do..
