My gpus always show higher clock speeds in unigine heaven/valley?

Apparent · Apr 1, 2015

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 same 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.

GPU boost will increase clock speeds based on variables. There is no reason a 980 would have clocks anything similar to a Titan X. Literally a 100% different chip. GM114 vs GM200. The only problem with the Titan X is how power hungry it is, which is its chief problem when overlocking. If you download GPUZ there is a thing under the "sensors" tab which says "Perf Cap Reason". Basically, whatever is says when you hoer your cursor over the area where the data is shown is the reason why the GPU is not boosting higher. It can be temperature, voltage (power consumption) or other reasons like a lack of load. GPU overlocking is a very very tricky science. Sometimes you can get several hundred MHZ, sometimes you can get 20. Really depends on the card. One Titan X could overlock great, another could suck. Damage caused by overlocking, and sometimes just overlocking can void your warranty and won't be covered.

Unigine Valley and Heaven are known to report false clock speeds for most Nvidia GPU's. GPU-Z or your graphics card overclocking software will report the correct clock speeds.
