Help Understanding higher clock speed in unigine valley/ heaven on every card?

[Apparent]

Hello guys.

I need some help understanding this please because I want to overclock my titan x.

I Was wondering why every GPU I buy it shows higher clock speeds in both the above benchmarks. I had a GTX 780 (not overclocked) GPU boost would keep clocks running at constant 1032mhz as opposed to the factory boost clock of 941mhz, which is of course normal,however in the above benchmarks it would run at 1228.

After buying the 980 similar thing & now I bought the titan x & clockspeed showing 1392.
I'm wondering is this benchmark showing the potential,or safe overclocking speed that I could boost to...?Is this the benchmark stressing the GPU to show this purpose?

Obviously gpuZ & after burner show normal speed. I have not overclocked before & have bought my first GPU 4 months ago & have now got my 2nd/3rd & want to learn about overclocking. Thanks in advance for you input guys.

AFAIK heaven and valley are completely poop at reading core clocks. Ignore them and use the ones in afterburner and GPU-Z.

Cards using GPU Boost 2.0 (all of yours) will boost above their given "boost clocks" as the values given by nvidia are minimums.

Spot on P. Ignore what the bench tells you and rely on what AB tells you

Thanks guys I will just rely on the usual afterburner/ gpuZ.I was just curious and thought it maybe be pushing the core at those speeds but yeah your right coz afterburner running at same time don't report the same.

Unigine Valley and Heaven are the best in terms of checking OC stability. As mentioned look at MSI AB for correct clocks etc.

You can actually calculate your GPU core and mem clocks yourself after testing @ stock.

Mine for example @ stock is 1189/7000 (read through MSI AB)

I run my OC stable at +250 (core) /+500 (memory, this adds 1000 to the total) = 1439Mhz/8000Mhz
