Folding Forum

I've just returned to folding after a break of a couple of years. My main PC is a Llano A8-3870K with an HD 7770, which was easy to set up.

I will be rebuilding an old PC over the weekend. The configuration will be:

Motherboard: Maximus IV Gene-Z
CPU: G2020 (dual core)
GPU: GTX 295

I will be folding with both GPUs of the GTX 295. Will each GPU use a separate CPU core? If not, will there be any poinnt to folding on the one remaining CPU core? I will eventually be upgrading the CPU, and I know I will then be able to fold with it, just unsure how many cores the GPU client uses.

Also, the motherboard is faulty and only sees memory on one channel. Will I be better with a single 8 GB 1600 MHz module, or a pair of 2 GB 2133 MHz (in single channel) for folding?

The GTX 295 is going out of support. Core_11 projects that ran on it ran out at the end of the Summer. There is some assignments of Core_15 work being made to pre-Fermi cards such as this under the beta setting, see this post - viewtopic.php?f=18&t=27134&p=272653#p272653. No guarantee it will work on your specific model card.

Core_15 for nVidia usually uses very little CPU time, so you can adjust the CPU setting to use all cores you want to assign to GPU processing. Reserving one CPU core is needed for later GPU folding cores running on nVidia.

Thanks Joe. I'll look up how to add the beta flag and will use that until I can upgrade the GPU
