I recently bought an Asus 5870 on clearance intending to Crossfire it. Before even beginning to attempt CF though, I installed in my system (alone) to test and everything seemed fine until I started to try a few games.
Without fail, the card will seem to be fine but without fail, usually within a minute of gameplay or when a larger scene is loaded (ie: walk from inside a room to outside a building which is much more intensive on resources), the card will hard crash and will freeze, with the fan on the card jumping to maximum speed (hairdryer mode) and the system hanging there with a black screen.
I haven't had any experience with the behavior of videocards where there PSU has been inadequate so I was wondering if this was a dead card or if these symptoms could perhaps indicate a power issue?
I have a 700W PSU with 50A on the +12V rail which should be perfectly adequate. I don't however, have any 8 pin PCI-E power connectors, of which this card requires one. I connected a 6-pin power connection and for the 8-pin, I used the molex adapter that came with the card. Could this be a reason for what is happening?
Eventually, I tried crossfire as well and had the same results, I swapped both cards in the slots and the same thing happened. The ASUS 5870 will hard crash quickly after 30 seconds to a minute or when I go into an intensive scene.
IE: I loaded a saved game of The Witcher which was saved inside an inn. While I am in inn, everything is fine. When I walk outside, it will work for a few seconds and then the screen will black out with the ASUS card jumping to max fan speed (like a card does when it doesn't initialize properly or has power issues).
When I turn off crossfire and remove the bridge and leave both cards in the system but only with my old XFX 5870 as the primary card, everything runs just fine. However, like I said before, I tried the system with the ASUS card only and it continues to crash in the manner I described.
