FAHControl does not use 7850 Gpu - Help - Page 2

post #11 of 14
You may be folding single core units. I am not certain how to check that. Also, while folding an amd gpu, you will have to set your cpu to fold with only 3 cores, as the gpu needs to use one of the cpu's core.

how can i see how many processor cores it is using? its preset at -1.
and how do i set it to 3 cores? with VM like juano mentioned?
post #13 of 14
vm is virtual machine. What juano was talking about could be done with this guide http://www.overclock.net/t/757170/vmware-guide-to-folding-a3s-in-a-vm. It is somewhat advanced, but not very hard at all to do.

As far as checking to see how many core you are using, you could use open hardware monitor, and check the usage. You could also go to your task bar, right click, open task manager, then click the performance tab and see what your cores are doing.

-1 is the default auto amount, so basically it will use all of the threads you have.

What you need to do to make it use just 3 out of 4 threads, is to first right click your CPU SMP folding slot and then select finish, then wait until the CPU finishes the current WU it is folding. If you do not wait until the WU has been finished folding then the WU will be lost, and losing WUs is a detriment to the research being done and should be avoided if at all possible. When the CPu has finished it's current WU and stopped folding go into the configuration menu, go to the slots tab, select the SMP slot, then click edit. In the edit window that will pop up in the SMP section under the CPUs field change the default value of -1 to a 3, then accept the changes and resume folding.

If you later want to change to a Linux VM, then in the initial set up you will just choose the amount of cores you want to run it on.
