I know with the 940 no matter how cool I got chip it electrically it could not pass prime at 4gig.

Also you will want to do this with ram and NB and HT backed off......eliminate everything from the equasion......thats how I test cpu's, Once you know cpu can pass you work on everything else individually until it starts failing.....this makes it far simpler to diagnose individual problems...



Lastviking the key to your 64 bit stability could certainly be the fact that you are running 800 ram speeds.......Might be on to something here.....
Somethings is not right with 1066 ram speed... i will try to figure it out, it will make WinXp crash after sometime and also corrupting files, thats why i have left it @ 800 speed now. Dunno know if its are the IMC, Ram, High vdimm or something else. But my sticks are rated 1066 2.1v 5-5-5-15

The 1066 speed problem started in WinXp have not tryed to change to 1066 and tested that in W7 yet.
