here is a wierd one for you.

When posting at 167Mhz x 20 which gives me 3340 Mhz, it see's all 6Gb of memory

How ever When posting at 168Mhz x 20 which gives me 3360 Mhz, it see's ONLY 4Gb of memory

Any idea's? Memory is corsair non dominator stuff rated at 800Mhz, currently at somethign like 835. Got 1.65V going through the ram, so all should be fine.

The processors primes fine at above 3360Mhz (primes fine for 12 hours at 3.5Ghz) but i only just noticed it was on 4GB and not till i went back down to 3360 did it post showing 6Gb of ram grrrrr

Please help

Phil
