I've downloaded all the drivers i could find and did all the windows updates but I've still been getting various bods while running vista with the default bios setting. The most common one is Driver IRQL not less or equal.
The DDR2 800 kit should be set to 4-4-4-15 @ 2.1v and the DDR2 1066 kit should be set to 5-5-5-18 @ 2.1v.
You should also run memtest86+ overnight to check for RAM errors.
What are your idle and load CPU temps?
My Ram is DDR2 1066 set up 5-5-5-18 @ 2.1v.
Also I'm running the system from a 500W psu so maybe a power issue? I've been reading around the boards and also suspect maybe a driver issue with my firegl v3600
Idle cpu temp is 41C and i haven't gotten the software to get a load temp yet
