Thanks for the answer. I did see an improvement after installing a opencl driver, but i didn't know if i had 'check' the cpu box in the render benchmark for it to work.
Too bad I didn't see these posts sooner. I rebenched my M6F & 4770K and noticed at 39X my GPU temp was 55+, as I went faster, the GPU temp went down. At 47x47x46x46 core and ring at 44, I was seeing no GPU activity at all, 0% GPU. The temp was 28-30, just like when the stress started. With my Nvidia control panel, I forced the Physx to GPU and now, at the same clock, my GPU is 100% at 56 degrees.
So, I'll turn it back to auto, but it's good to know I didn't fry my card or something! 😄
BTW, when the OpenCL traffic goes to my CPU, the stress test seems to work OK...with one exception. The LuxMark application window doesn't display any info about the hardware, and the window never has any graphics drawn in it. I guess that makes sense if there's some "virtual" display that OpenCL operates on when in CPU mode, but I'd have expected some message or other indication that the test was going to CPU instead.
for opencl intel drivers just google-->opencl driver intel 😛 or KLIK
