Thanx in advance
I am afraid this is is a driver error related to the GFX...

I too had this exact same issue with GeIL Black Dragon 8GB kit and despite a number of tests was only able to get 8GB to run in Vista 64bit Ultimate in SAFE mode or after a fresh install of GFX drivers --however upon reboot there would still be the BSOD--it is not Voltage dependent/timing dependent--it is related directly to having GFX drivers installed. 2 GB or 4GB will work but not 6 GB or 8 GB--no matter which slots are used or which sticks are used...I spent 12 hours in one stretch trying to work through the problem.

My Vista 64 bit Ultimate is fully updated/patched/hotfixed.

I do not think it is related to the G Skill or the GeIL in particular--I think it is a bug in how 64bit uses more than 4GB pf RAM once GFX drivers are installed...a real shame.

If I thought it would be different with a different MFR I would try any brand to see how 8GB performs...I aslo tried a number of GFX drivers to see if it was a DX 10 issue.

A non HW issue like this may be hard to resolve without getting MS off their butts to make some efforts and likely would involve the GFX drivers or some sort of patch there. Simply working with the RAM mfrs to resolve this is probably futile--as it seems to be a SW/OS/Driver issue peculiar to Vista 64 bit.

Seems like more MS BS to me--making an operating system that claims to use more than 4GB of RAM--but can't.
