What clock reading to trust?

[jonasa97]

Hi,

I've been messing around a little with afterburner and everytime I stress test with unigine valley the apparent GPU clock is 50MHz higher on the reading of Unigine valley. What reading should I trust? I'd like to believe my GPU is running at 1261MHz but both afterburner and GPUz disagree with that. Please help!

It may be an idea to download a 3rd third-party GPU monitor program such has HWmonitor then check to see which reading that gives out. I would tend to go with the reading GPUz gives you, but that's just me and i don't really have a reason for that :/

 

EDIT: Misunderstood, my bad. Yeah go with GPUz and Afterburner readings.

Unigine does that, maybe someone can explain why. However the correct clock speed will be displayed by afterburner and gpuz.

I have another question concerning my GPU overclocking. No matter by how much I increase the increase in MHz on afterburner, it just won't go above 1202MHz. Can anyone explain this? do I need to change another setting to go higher? (I haven't made any changes to the V -core yet)

Unigine shows me the same frequency whether I overclock or not and it's always higher than what gpuz (and evga precision x in my case) show me, which is what the clocks actually 'should' be based not my overclock. Not sure why unigine does that, all I know is that it does :D

Yeah, my clock readings in both Heaven and Valley are off by as much as 150 MHz (I wish I could run at 1300+ MHz ), trust After Burner and GPU-Z.

I've never used afterburner, so I couldn't really say. But 1202mhz is a pretty high clock speed already, what are your temps?

Unigine gives inaccurate readings. Personal experience.

My GTX 680 can do 1228 and GTX 770 > GTX 680. You can definitely do more than 1202.

Push vcore to the max and temp target higher (about 90C if you're comfortable)

My GPU doesnt exceed 67 degrees while under unigine valley load. my question is... do I have to increase the Voltage so I can increase the clock more?
