So I just got the black edition 7950 in the mail today and im having some black screen crashes. sometimes on boot and a lot of the time right when i start a game. whats that all about? bad card or bad drivers? its really annoying because I was really excited for this card frown.gif

Sounds like a bad card. RMA.

Try this: Uninstall AB and Trixx and then make sure you have a fresh install of 12.4 (use atiman uninstaller to do this) and then install afterburner 2.2.0 and put in the unofficial overclocking EULA thing in the config and make sure to set unofficialoverclocking to 1 instead of a 0. Next go into afterburner and hit settings and then make sure you have "unlock voltage control" and "unlock voltage monitoring" checked so it is actually regulating the voltage for you. Next up the voltage and click apply and get yourself into something windowed like kombustor or whatever and while it is running check to see what the voltage is in afterburner (you dont need gpu-z for this as it is built into afterburner). It should be regulating your voltage up now when you are in 3d programs.
It seems like you are missing one more of the steps to ensure voltage regulation in AB - I hope following my instructions help. It should be very easy to get this to work provided you have done all of the options correctly. Let me know what happens.

If you want to see true voltage use hwinfo64. You can get an idea of your true base voltage by checking your asic % with gpuz. Then set AB to the core type following my post below. I would just uninstall everything, go to control panel uninstall all amd crap. Reboot, then grab driver of your choice and follow the post.
Also, don't use kombuster or any of those lame heat inducing wannabe benches, furmark, atitool, whatever. Use Heaven to get you stable, then use crysis or bf3 to actually prove you are stable.

Thank you!! Finally works. So far stable at 1180 and 1650. Haven't tried higher yet.

Glad to be of service and glad to see you got your OC sorted out. thumb.gif

Hey guys I just had the first problem with my GPU. I had no issues what so ever on my last build, but I recently replaced my core components and then this just happened:

I was listening to some music doing some stuff away from the computer and the monitor went to sleep after 10 minutes and the music was still playing. When I was done what I was doing I came back to the computer and moved the mouse to get the screen back and when it came back on there were horizontal lines across the whole screen that were yellow fore and I think also blue and gray. The whole screen was lined with them and I couldn't see anything else. The music continued to play until the song was done, but stopped playing after the song was done even though there were more to play which I found odd. I tried to shut down with the power button, but I had to hard restart.

Any idea what this could be? I haven't played any games since I got my new build up a few days ago, but I have the same settings on my OC on afterburner and I did do some tests to make sure it was stable in 3D rendering environments.

Thanks for any input.

Disable the monitor sleep like in someone's previous post. It's still buggy and does the same with mine. Mine won't even wake.

Well my xfire woes are gone now with 12.4. Never had an issue with single card config.
I have binned MSI afterburner.
Using modded trixx with moar volts and memory volts.

I am now a satisfied customer of AMD.

Agreed about the overclock capability , but based on my experience it somehow indicates the amount of voltage a card needs for same clocks. Tested 2 other 7970s with asic above 80% and they were capable of 1125 with 1.11v , while mine (63,5%) needs 1.16. On the other hand , above 1160 they would artifact regardless the voltage , while mine is artifact free till 1290mhz but voltage thirsty.
So yes, in general, asic has nothing to do with the o/c potential.

Now running 1200/1700 at 1.150mV 24/7 stable. Happy with that!

Can anyone tell me if there is a program that will let me run my ref sapphire 7970 past 1.3v

I can get to at max 1340/1800 @ 1.3v but get artifacts

At 1325/1775 @ 1.3v with temps aroundlow 40's - 45 benching its stable but i want to push it further if it possible. thanks
