I am trying to crossfire two Sapphire Radeon R9 280X (Model: 11221-00-20G) and I am running into instability issues with stock clocks. I get green streaks / artifacts and a eventual crash. At stock clocks it gets to about 81c then that's when it crashes.
System specs:
Intel 3570k OC to 4.6ghz with a closed loop Corsair H50 liquid cooler
Thermaltake 850 bronze (http://www.newegg.com/Product/Product.aspx?Item=N82E16817153158)
1 64gig SSD, 2 500gig 7200 rpm SATA
Asus P8Z77-V LK Z77 LGA1155 Motherboard
The powersupply and motherboard was ordered on November of last year so they are pretty new.
I have taken out each video card and tested them individually and they seem to run ok, however it is hard to duplicate the issue. It seem's to take about 45+ minutes of gameplay on crysis 3 or metro last light.
I have also tried to re seat the cards, tried different slots, different crossfire bridges, disabled the powersaving feature in registry, checked bios, and I still have the same problem.
What makes me think it is a card is because I tried hooking up a 7950 with a 280x and was able to crossfire that with no issues, further, I was able to crossfire another 7950 with no issues. My case has 5 120 fans.
The extent of my single card testing was really only running firestrike once. I don't have the time to commit an hour of gaming.
So my question to you guys, is there a way to safely, and individually test my cards to narrow down what the problem is? What is the normal temperature for these cards?
