Despite running benches in Heaven and Furmark I get ''driver not responding and has recovered'' after gaming for a while in Batman : AA
I am running at 1175 volt and default voltage for the memory.
What would you guys suggest? Just try running abit lower (lets say : 1150 core and 1550 memory) or upping the voltage a little more?
I am getting low 70 degrees in Furmark, low 60 degrees in Heaven at 1175 voltage.
Thanks for your advice !

You've got some wiggle room there dude, I reckon bump the voltage to 1.181v.

I've been an Nvidia owner since Riva TNT2 and the 7970 is my first AMD card. I've heard people with problems with AMD drivers and they are not up to par with Nvidia's. I was a nonbeliever as Nvidia's drivers were always so smooth and I would think it's just user error with AMD's drivers since why would they release something that is unstable and doesn't work? Especially for $550?

Picked up my 7970 during launch and expected it to run flawlessly because I thought people were just idiots and couldn't do a clean enough driver install. Turns out, I was one of those idiots. It took me a good 2-3 days and much headaches to get it working. I tried multiple fresh installs, went through every variable and it didn't work. On my final attempt before I throw my card against the wall, I did what I normally did. Fresh install of Windows for the 100th time and it worked! How? No idea. I haven't touched it ever since. It's running on the Jan 9th drivers, which I think are the RC11s?

Yes the drivers do work and I am happy now, but when this thread is near 700 pages, 300 pages are about drivers, something is wrong AMD! Not everyone is willing to spend hours troubleshooting their cards to get it to work. I am sure Nvidia drivers have problems too, but at a much lesser scale of AMDs. At first I thought people were just blowing up AMD driver problems out of proportions but they have a reason to.

Make your drivers better for us idiots who want to plug in card, install drivers, and play games! Not plug in card, install drivers, BSOD!

I am only using Furmark to see what my max temps will be, nothing more. I am using games to test stability as you can see from my post wink.gif
But I will try upping voltage abit more like suggested here.
Thanks for the feedback!

Does anyone know what leads I need for my PSU, 2x 6pin to 2x molex or 2x 6pin to 1x molex ? (my PSU doesn't have extra 6pin leads)
Rep for answers thumb.gif

Donno Focus but you should make sure that you have plenty of power to run 2 of these cards. I don't even think I could run 2 of these on my 800 watt PSU.

Haven't got to read everything yet to see if these were mentioned, but ... biggrin.gif http://support.amd.com/us/kbarticles/Pages/HD78007Support.aspx - Tested with BF3 and they work for me very nicely. smile.gif Untnstalled everything and installed these drivers fresh. I think they're very nice drivers.thumb.gif Oh damn, I didn't realise that these may not work with 1080p monitors. :/ Ahh just did a dirty install from the RC 11.12 to these and they work fine again. Working on a new 1080p monitor. biggrin.gif

Same as, I did a complete W7 wipe. Guess what!? My windows still hangs at loading screen sometimes with crossfire enabled

Must be a "fresh" installation.

These drivers messed up my windows 7, had to reinstall. Now I have same issues I had with every other driver in xfire.

I run 2 7950's on a 750watt without any issues, this includes O/C on the CPU cards. I guess the next test will be adding the water cooling to it.

You can easily run crossfire 7970's on a good 850w psu like a Corsair TX850 HX850 or AX850. The 750w's don't have 4 pci connections and isn't recommended to use molex adapters. You will run into power issue's like that. I have my 7970's up to 1200/1600 with a 5.2ghz 2500k and water cooling and the most I've ever seen form my UPS was 765w.

I played about 3hrs of BF3 last night on RC11 in Eyefinity with Ultra settings and 4xAA(in CCC) and enabled Vsync this go around. FPS never dropped off of 60.1. Game looks so nice in eyefinity. Not 1 crash or problem at all.
