Latest update...
Left PC plugged in to mains overnight with latest bios FC2 and.... still BSOD on cold start up this morning I ran MemTest86 straight away and was getting 300+ errors in the first 5 secs!! I rebooted and set the DRAM v from 1.5v to 1.65v and reran - suddenly no errors. Switched back to 1.5v from 1.65v and still no errors. It is not the DRAM voltage - I am running at 1066 which according to the SPD spec runs at 1.5v.
I am stumped... it has to be either the memory or the motherboard. This is bizarre. Is there anyone else out there using TR3X6G1600C9 with the GA-X58A-UD3R rev 2.0?
Next steps:
a) RMA the memory?
b) RMA the motherboard?
c) RMA both?
I am inclined to think it is the motherboard/bios - the reason for this is that the memory works fine with bios FA. I will reflash to FA and leave off overnight and see if thiis confirms it.
Dark Mantis - what do you suggest? I still have not had a reply from Gigabyte.
Google has sent me this way as I have almost exactly the same issues that you do.
My specs are as follows
OS Windows 7 Ultimate x64
CPU Intel Core i7 920 D0 Quad Core CPU 2.66GHz
Motherboard Gigabyte GA-X58A-UD3R
Memory Corsair TR3X6G1333C9
Graphics Card XFX GeForce 9800 GT OC 512MB GDDR3 PCI-Express
PSU 650W Corsair CMPSU-650TX, single 12
Hard Drives RealSSD C300 64GB 2.5" SATA 6Gb/s
RAM:
Corsair XMS3 6GB CTR3X6G1333C9
and I'm currently running 3x2gb of Corsair XMS3 CM3X2G1600C9
As you can see from my thread here I've been having plenty of issues!

http://forum.corsair.com/forums/showthread.php?t=89780Essentially running the FA BIOS I had no BSOD issues, but had the missing memory issues. Update to FB and I have all 6gb but loads of BSOD issues. Thought it could have been the BIOS, played around with all manner of settings, got nowhere. Then put everything back to Failsafe Defaults and had a day of good running.
Next cold boot, the system POSTs fine and gets to the Loading Windows screen and will blue screen 100% of the time. The only way I can get the system to boot is to run the Startup repair from my Windows 7 ISO that I run off a multi boot USB stick. Running Startup Repair from the SSD doesn't seem to work.
I'm starting to suspect the SSD is now corrupt and haven't had time to check it. However, I'm also very tempted to RMA the board, as it doesn't seem fit for purpose and I seem to have read a huge amount online about these boards having issues. Trouble is, I'm not sure which MoBo to replace it with.
FunkyErn: How are you getting on with your RMA?
