So to start with specs:
Crossfired Sapphire Ghz edition 1G GDDR5 7770s no overclock.
(299-1E214-000SA + 299-1E244-001SA) Stable drivers I'm using are the 13.12 edition.
Operating system is Win7 64bit Home premium S.P.1.
Issue details are.. After removing and cleaning the 13.12 drivers I've rebooted and installed the 14.1 Beta drivers, all seemed well untill you go to run a game and Pow! BSOD!
Upon rebooting and scanning through the web for any obvious fixes Bam! BSOD! After a further reboot I decided to dissable crossfire, just to see, and the driver becomes stable!
So I think there is a problem here somewhere...
For the rest of the info:
Motherboard is an ASUSTek M4A77TD pro.
Power is from an Ezcool ambiance 80+ 800w.
Display is a DELL P991 1600x1200 utilising VGA to DVI adapter.
Every application and game is affected.
Phenom II X6 1040T not overclocked.
BIOS American megatrends Inc. Version 2301. (08/11/2010)
8Gig of Corsair DDR3 NB frequency shows 2008.9MHz (2X4 sticks, paired)
2xSATA HDs and 1xDVD RW 1xExtra fan for cooling.
Hope that helps to sort this driver out as running MWO on a single card seemed to net a 15+ fps boost. Nice.
