post #411 of 38704
Is anyone able to read if volts do increase with GPUZ? GPU Tweak is telling me they do but GPUZ is saying they do not.

GPU Tweak is acting weird so I haven't had much chance to play with the overclock. rolleyes.gif For whatever reason my framerate is pulsing whenever I have GPU Tweak open. Even the GPU Tweak monitor. BF3 will go from 90 even for a few seconds and then spike down to 70 and right back up. Same thing in OCCT. Can hear the inductor squeal go along with it. Might have to mess with AB to see if it does it.

When you say you spikes from 90 to 70, would you consider it stuttering? Or just normal frames dropping but still very much playable?

There shouldn't be a huge variance of frame rates when you are running OCCT.
It's probably still throttling even though you set PT to +20%.
There must be a way to increase it...

I've got conflicts everywhere.

Gpuz says 1.17v. Afterburner says a myriad of things. Trixx says 1.17. Tried applying voltage with both trixx and afterburner.

AB and GPUTool report the same load voltage.
GPU-Z and Trixx report 1.17v under load?

I'm convinced that AB isn't the best tool for this card. I'm ready to try some others. What other software and versions are you all using.

Another side not for those with 570's. With BF3 I would say if you game alot with BF3 this may be a good upgrade for you I went into the smallest TD match map on BF3. Played for about 20 min on stock. And was using about 1500mb plus of VRAM the little hicups I got with two 570's in SLI are gone even though the frame rate is much lower its still overall smoother even with FPS dipping to 40fps its still smoother cause I don't get the same long pauses that 570's would exhibit.

But again like I said earlier I'm having problems with downclocking during desktop mode. with some artifacts ever so often in desktop mode this has to be driver or power savings related. And might only be for those who have 120hz like myself. This hopefully will be resolved with updates.

im guessing they havent been updated to detect applied voltages properly

With only CCC open at 1100/6000 it's perfectly steady in OCCT. With only GPU Tweak open at the same clocks it stutters. It's not a normal couple fps, it drops 20-30%. It's very predictable 2-3 seconds fine, half second stutter, 2-3 seconds fine.

Edit: I'm not leaving both open to fight or anything. tongue.gif

After using AB for my card, it seemed to be inputting less than the voltage I specified. Switching to ASUS Tweak, TRIXX if that doesn't work.

EDIT: Whats the stock voltage for these cards? 1.17VCore?
