Confusing GPU clock speed on GTX 760's SLI

post #1 of 3
Thread Starter 
I have MSI GTX TF N760 card as my primary GPU and ASUS GTX 760 Direct CUII OC as my secondary GPU. I've overclocked them by a few MHz and when I run Metro Last Light benchmark, I see GPU clock speed reaching 1240MHz + on both the GPU's in the benchmark.
But according to below screen's you can see that my GPU Boost Clock being 1181 MHz and 1168 MHz.
Why is it displaying 1240+ ?

I think GPU-Z only shows the gpu clock and boost clock but doesn't take Kepler Boost into account.

My top 670 is 915 gpu, 980 boost but actually runs at 1097 with Kepler Boost.

My bottom 670 is 980 gpu, 1058 boost but actually runs at 1150 with Kepler Boost.

To see the actual clock under boost, click the question mark in gpu-z beside the Bus info, a render test box will come up. Then set gpu-z to the sensor tab & start the render test, the actual clockspeed it is running with the kepler boost (as said below, kepler boost is like a hidden boost) will show in the core clock box.
