Are you using normal bios for both cards or boost bios?

Have you disabled ULPS?

What is your power limit?

Voltage?

I'm flashed back to the original. Boost BIOS on both cards.

I have disabled ULPS

My power limit is set to 20%

And my voltage is at the stock boost voltage of 1.25v

Why do you ask?

Was just asking to see what your settings were. I been running CF for few weeks now. Here is a ss from unigine valley



Alright i guess, i was hoping to get better performance.

Yea that's pretty much the same score that I have. I just have 150 more points then you. What are your clocks, cards, and voltage?

GPU Clock: 1150

Memory Clock: 1500

Voltage: 1250

GPU1: Sapphire 7950 Boost OC edition

GPU2: Sapphire 7950 Vapor-X OC edition

Also on boost bios for both cards. Disabled ULPS

Are your GPU usage for both cards jumping around? Mine are. It's quite annoying. I'm playing a part of Crysis 3 where there is constant explosions going on and my FPS is jumping around like crazy down to around 30 and back to 60 and I exit the game and see that my GPU usage on both cards is jumping around from 50% to 100%. I would like to think that if the game is struggling that the GPU usage would automatically go higher. I guess thats not the case.

It looks like PowerTune is kicking in to clamp the board from overdrawing its current circuits and/or protect the board from what it believes is an oncoming thermal event. Both are possible at the voltage and clock you're running.

Thanks for taking the time to post! Much appreciated! Is there anything I can do to turn PowerTune off? Or would I have to lower my clocks/voltage? I am running at the stock boost voltage of 1.25 and havent messed with the voltage at all. Voltage control isnt even enabled in AB. I was thinking it might have been a CPU bottleneck, but I guess not. I'm running an i5 3570k @ 4ghz.

Make sure you have AMD CCC Disabled. Go into your ab and make sure to unlock voltage control, monitoring and force constant voltage. And Make sure your voltage is set to 1250.

How would I disable CCC?
