Well, I have noticed that my newer Gigabyte card runs slightly cooler than the older one. About 2C cooler on load (testing with 3DMark 11 and Heaven). That could be due to airflow as well. Not sure if it's ASIC quality or not. I'll try OC'ing the cards further than their current speeds. But ambients are ridiculous right now in Malaysia at around 30C leaving my case temps around 38C and I can't push the cards too much until I get an A/C for the room with the rig.

OK, I'm learning slowly that my crashes are due to my overclocks. But they are minimal, and it keeps crashing.

I have the Sapphire Dual OC, which hasn't gone over 70C, and isn't stable at even 1085mhz on my stock voltage.

Shouldn't my card be able to run 1085 and stock memory without adding voltage?

Overclocking --->

So my voltage in GPU-Z is .95 at idle, and then with AB 20% Power Limit, and max voltage in AB turned up to 1.2, and 1175mhz and 1550mhz memory, my voltage never reads above 1.08 in GPU-Z.

All my GPU programs show my stock voltage as either 1.17 (Gpu Shark, Msi Kombustor) or 1.05 (Msi AB 2.20).
GPU-Z 6.0 shows my stock voltage on Bios Switch 2 (1000mhz, 1450mhz memory) as .95.

I'm guessing GPU-Z is the accurate one, but how can my voltage be that low compared to the rest of the cards?

In a stress test right now, at 1175mhz and 1550mhz with 1.08 voltage, with 83% fan, it's at 82C.
At 1200mhz it crashes, and voltage still never goes above 1.08. How can I get the voltage up? I have the slider in AB at 1.2 max.

Trixx- Now, using Trixx, the voltage in GPU-Z shows up to 1.17 under load, with 20% Power Limit.
Stress testing 1185mhz and 1550mhz memory.
I'm running Msi Kombustor with Trixx overclocking, and the voltage and Gpu load are all over the place. Voltage is anywhere from 1.06 to 1.13 and Gpu load is 30%-65%.
Why is overclocking so damn confusing?


Thx for any help.

Man, I'm a little sad. I just posted two 6950s from my old quad array for sale. I ran those things for so long and went thru the early teething problems till they were matured.


I think I accidentally bought a 680 lol. I used the funds from stuff I sold from the wife's computer lol. Don't tell her. Will sell 6950s to get replace, sssshh.

Anyone have any ideas how I can get this voltage thing stable and sorted out? Thank you. My original post is 2 posts up.

Also, any driver out that doesn't crash when using dual monitors? I want to game and monitor my temps and such on my 2nd monitor, and it just keeps crashing. Amd drivers are freaking frustrating!

So you aren't selling them now? sad-smiley-002.gif


Also, ambient of 72F = 22C, so I'd reckon it's about 25C here right now, in winter at 3:30 PM...

Not too much hotter than you though... hrm

It sounds like your programs are not properly regulating the voltage of your card.

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.

Thx for any help.

One, your voltage could never be .95v, lowest is 993mv give or take. 950mv is actually the idle voltage. Regardless none of the apps you used actually reads true voltage, only intended voltage. 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.

Gonna try lowering the voltages to 1.125mV, getting a bit optimistic but still wont hurt to try smile.gif

Tested on Skyrim for 10mins, everything ran fine and temps were below 60 smile.gif Doing Heaven benchmark now, then on to Battlefield 3 if its alright

Skyrim is no test tongue.gif Vanilla uses 40% of my overclocked 7970, and even with full S.T.E.P I usually only see up to 90%
