now this is interesting..

btw do you have a copy of vista 64 or xp 64 to test with? just to rule out if the problem is related to windows 7 x64 or just a hardware problem...
Hmm, no I dont have any copies, I only have an XP x86. Due to the fact that I hate Vista.
The chanel thing might point to the Memory Controller problem that was mentioned above.
