Hi all,
Have you focused on the power of the k20c?
I used the SHOC benchmark to test the k20c. And the max power of the k20c is just about 150w, and it would not be bigger than 160W,even thoug the GPU utilization is reached 99%…
I have tied the SHOC benchmark on Quadro 4000/Tesla M2090/Grid K2, the card’s power could reach 95% of the TDP. So, I think the benchmark tool is no problem.
I just doubt something is wrong with my k20c.
By the way ,I have checked the Power limite is 225W.

Could anybody help me to confirm this problem?
or could anyone recommend one test tool?
Thank you.
