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.

That OC is clearly unstable I think the voltage on the core is too low. Damn too late

Good to hear thumb.gif
I'll take the new modded Trixx over AB any day of the week, that's for sure wink.gif

Anyways, I'm not going to make the jump till you guys get it sorted, however I'm not ready to give up my OSD either. I also, haven't had much issue overclocking on AB with Tahiti. On Caymen, that was a whole other story.

It's interesting though... maybe Trixx has figured out the driver hash mystery... hmm.

Got my Sapphire 7970 OC today. Sitting at 1200/1800 @ 1.260vddc. Haven't tried higher volts as I want reliability.

I would have liked more FPS on eyefinity though. FPS lower than Id like for multiplayer in BF3.
For single player, I can turn all to max nicely tho. Looks awesome.

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

AB will let me set voltage as high as 1350mV but I still get artifacts at anything over 1240mhz. Im guessing Im at the limit of these cards? If so, that still aint bad...

Yeah sounds like it, still a massive overclock and a big jump from stock performance though.

Btw the artifact issue is probably due to aircooling.

Ooh just played crysis warhead at 5780x1080 all maxed. Always 30fps or above. Pretty sweet.
