MSI GTX 680 Lightning. Core issue. Please help.

post #1 of 12
Thread Starter 
Hi there

I recently bought a brand new MSI GTX 680 Lightning. After a few benchmarks, i've noticed that the core memory is 700 MhZ, when it should be around 1110. Any thoughts on what might be the cause of this, or how to change it?

My set-up is : ASRock Fatal1ty professional-m motherboard
Intel i7 3770K
Corsair Vengeance 1600Mhz 16Gb (2x8)
Corsair enthusiast series 750W
Windows 7 Ultimate x64

Any help would be appreciated.
Thanks

Thanks for your reply.

I just tried that and it still is at 705 MHz

hey carnivorous!

thats just one of the P-states of this card. Power states*

Open MSI afterburner or GPU-Z and look at the mhz, then run a game or benchmark and go look at your corespeed after, it jumps to 1100 in games and goes back to 700 or even 300 while in windows

Just checked it with afterburner

Its seems that you're right. while in windows the core memory is at 325, but when in-game it is at 1110 so that seems to be it.

But why do the benchmark reports show a core memory of only 700 at the final results?

Thank you for your help

it only shows 700mhz becuase that is P2 state. P2 state never changes. (you can overclock it in nvidia inspector if you want, but this state never does any calculations)

P0 State is the one that goes to 1100 once you in benchmarks.

So basically its silly, benchmarks and GPU-Z read the P2 state clocks. But your gpu runs at P0 state during games and benches, and that is at 1100. or to whatever you OC it in afterburner

Thanks a lot! That explains everything!

if you are using 3dmark11 all 680 show 700mhz as the core, doesn't matter what your actual clock is at.

Not sure about other benchmarks but 3d11 is at 700 when it shows results
