hi,
i bought a week ago, to upgrade from my Sapphire ATI 5870, the PowerColer R9 290 PCS+ and got now problems with it.
If i am gaming (Assassins Creed Black Flag and Arma 3 atm), i get black screens after a random amount of time. Somtimes on startup of the game and sometimes after an hour or somewhere inbetween. After some seconds i can ALT+TAB out of it and and kill the game process in the taskmanager, that does say " does not respond". If i am lucky i can see at that moment a yellow triangle in the taskbar that says the driver crashed and will be restored.
After this happened the VRAM Clock will be fixed to 150Mhz in any 3D application, the Core Clock however moves up to 1040Mhz.
The System: Windows 7 Prof 64 bit MSI Afterburner v.3.0.0 Core I7 870 @ stock Asrock P55 Deluxe3 2x4GB DDR3 1600Mhz PowerColor R9 290 PCS+ @ stock
Samsung 840 Pro 256GB
Enermax Liberty 500W Powersupply
things i've tried:
- fresh install of Windows 7
- updating the Motherboard Bios to the newest verison (sadly from 1/20/2011)
- switching PCI-E Power Cables
- switching PCI-E Slot
- tried latest whql and beta driver (14.4&14.6)
- stressing the powersupply with max load ( 4 threads Prime95 and Furmark with Powertarget +30 and Core Clock up to 1080Mhz) got no instability there after 30 minutes.
is there anything else i can do or do i have to returne the card and try an other?
I would be happy to hear your opinnion
