I have recently just purchased 2 XFX Radeon 6790 graphics cards for a completely new system I had built and keep getting BSOD's, system hangs, and crashes.
The info is as follows:
Intel I7 960 - NOT OVERCLOCKED on an MSI X58 Pro Mainboard
12GB (4x3 chips) of Micron DDR-1600 - running at default timings set by the mainboard
A new certified 550watt P.S.
And finally the XFX Radeon 6790 with the single 6 pin power connector
Intel I7 960 - Not overclocked on an Intel DX850G mainboard
12GB (4x3 chips) of DDR3-1333 running at DDR-1066 (max the mainboard will allow)
Corsair 850 Watt P.S. (Certified)
And finally, again, the Radeon XFX 6790 Graphics card.
I've tried everything within my "playbook" as an ex-system builder to resolve this problem myself, including re-installing the entire O.S.
I've tried both Windows Vista64 Business N and Windows 7 Ultimate and get the same results: When I try to do anything involving graphics, the more intensive the graphics are.. the quicker it freezes, or blacks out.. sometimes with Navy Blue Lines?
I've heard some talk about memory timings, etc.. but don't know enough about that.. and don't see why that's "reasonable" to expect the average PC user to "re-time" their PC memory to work with this card?
Just wanted to add one thing. My system builder, built and ran the first system I mentioned for two weeks with no problem. . But the minute he delivered it, it started freezing. . And the only difference is that I prefer to use a wireless keyboard since the pc is part of my entertainment center. Will try to test soon to see if the wireless transmitter is the cause, if so: it may be an issue with an unknown driver conflict? Ie: Windows hardware polling?
