Different core clock in gaming vs benchmarking

[mikeschat]

Hello,

 

I am currently busy overclocking my Nvidia GeForce gtx 780 (MSI twin frozr).

When i'm benchmarking, i'm using unigine valley to check if my overclock is stable. 

During the benchmark, unigine states that my core clock is at 1381 mhz.

In MSI afterburner, my core clock is 1136 at the beginning of the benchmark, and it graduately drops off to about 1058 mhz.

When i'm actually gaming, my core clock is stable at 1136.

 

My current overclock is +140 on core clock and everything besides that is at stock.

 

Are all these different numbers normal, or is there something i should do?

 

Thanks in advance!

In benchmarks, your 780 hits the full boost clock. In gaming, your 780 does not need all the power so it throttles back to save power. That's why you don't see any effect while gaming.

That would make sense, but it's the other way around in my case.

In benchmarks i only hit the full boost clock in the beginning and then it slowly backs off. 

In gaming however, i do hit the full boost clock.

 

My temps are also fine by the way.

Maybe on the benchmark, you hit the temperature limit (if you not changed, i think is 80ºC), so the card decrease the clock speed. Also clock speed reported on Unigne is well above from whats is real.

 

If the game is running fine, I will not worry.

Gpu temps are around 66 degrees and i didn't change any limits.

But i guess it's fine then.

overclocking my 970 from the stock boost speed of 1329Mhz to 1554Mhz +225 i see about 7-10 FPS more in games so i just run it stock because im all ready above the refresh rate of my monitor
