I dont think your in need of adjusting any further voltages, with all others left at auto you should be fine. Are you able to confirm if this 6gb is running at the rated 1066mhz? Also are you able to boot the system into Windows at all? If so, are you able to run CPU-Z and provide us with a screent-shot / html page / validation page of the memory tabs at all? As a test, can you try 3 sticks at any time in the various slots? As you say you have swapped all the sticks arround to prove they all work, I am just wondering about the posability of a fault on one of the memmory slots on the mobo. Are you able to test using 3 sticks in various slots to determine if any are faulty... if one of them are faulty, then you will see your inserted 3 sticks of 6gb, drop to 4gb, which would be an indication that one of the slots are potentially faulty. Please post your findings.
Thanks again, I have tried 3 sticks in all variations and and all slots, all is ok, runs 6gb. I'm off to work but have jotted down some settings cpu operating speed - user defined 2399 (266) external clock - 266mhz multiplier - 9 cpu clock - 2394 dram speed - default (ddr2-798) ddr2 ref volyage - 0%
