Yeah. I have found that 1T will be memtest stable, then need 0.5v to retain 3D stability. I have tried tweaking drive strengths to no avail. Sync can cause issues... as well...same deal.

Also found that chipset volt issues can be hidden by over-volting mems...this will lead to 4-5hour stability( for me, but that may be jsut the DIMMs i got), but then BSOD/dump. But i found that TDU will not load if this is the case...


Sync requires avg 0.15v chipset more than unlinked. FSB drive can help, but i have not found more than using .05 less, so cannot be bothered ATM.
