OpenCL GPU&CPU?

[GoosNL]

Hallo,

I'm new around here so here's a short intro...
Name--> Goos, from Holland
pc--> asus hero mb, 4670K, 16gb corsair vengeance LP, gtx780 dc2, psu coolermaster 750

Can i enable the cpu for openCL benchmark? or would this be cheating?
I have noticed that the cl benchmark does't improve the overall score much,
but i just would like to see the differance.

Here's my currect score

CPU OpenCL is automatically used if a driver for it is installed. And no it is not cheating:)

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.

The benchmark is automated, no need to click anything after it's started 🙂

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.

Thanks,

That means there is a problem with your system. Bad OpenCL driver for the CPU most likely. When your system is fine it will show everything.

Anyone have a link for opencl AMD and Intel drivers?

AMD - 8350 and 9370
Intel - 4770k and 4670k

Thanks!

for opencl intel drivers just google-->opencl driver intel

See post below...

That's not the driver. As MarshallR said the driver is part of the Graphics driver package. The link above is the OpenCL SDK (Software Development Kit) and it's for developing OpenCL applications.
