OK i built my own Desktop and it worked fine for the past 6 months
the specifications are
Amd Phenom X6 1090t Black edition
Asus M4a89gtd pro/usb3
Cool max Cug-950b 950W Psupply
2 XFX hd Radeon 6950 in Crossfire
8gbs of Ram (2x4gbs)
Yesterday after restart i got no display. its happened before but with just some reseating i fixed the problem
this time however nothing i do seems to make a difference
so far iv reseated everything, removed any dust iv seen, cleaned the connectors, and reset the cmos
I tested with the onboard graphics and it works however i can see the fans on both cards spinning so im guessing they are working too im pretty much competly lost here any suggestions would be awesome
Do you guys think thats the problem. Since they both work solo? even though it ran both of them just fine for like 3 months?
I don't know. It's possible. It could be one of your PCI-e lanes. It could be your Crossfire bridge. It could be one of the PCI-e power cables. It sucks, but there's no guarantee without testing everything.
Even so, the PSU is important, so I'd recommend getting a new one if you have the money, whether or not it fixes this problem.
well here. ill explain why if worked well 3 months ago and doesn't now. buying a poor quality power supply and maxing it out by 80% for a while can "ware it out" so a better quality and with two 6950's that eat more power than 560 ti's in SLI....a 850 watt will be good. you should be able to find a good quality one for a decent price. you want find one below 120 or so tho......
Cant hurt to pick one up locally so it can be returned if it isnt the issue. But im guessing it may be. Low quality PSUs degrade over time cause they arent rated at the wattage they claim. So you are constantly pushing its limit. Id give it a shot and see if a new PSU solves your issue. Antec Earthwatts, Seasonic, XFX, Corsair, all good PSUs and shouldnt need more than 750 or 800 watts if its truly rated at what it says. As was stated above.
