do NOT lock cores to specific CPU

[Gaara]

Hey guys,

I am using the system tray cpu version of folding @ home on a core 2 duo machine and i am a bit confused about this option in the advanced tab:
do NOT lock cores to specific CPU

It was unchecked on default but I read some info on it and decided to check it. Is this supposed to give me a peformance boost or is it better left unchecked?

Also, do I need to install 2 clients if I decide to leave it unchecked?

Probably nooby questions but thanks in advance anyway!

I don't know the answer but I have found the Folding Forums useful at times:

Could you let me know what version you installed (uniprocessor, smp, gpu)? and whether you have a dual or quad core cpu?

Some users have gained a slight performance boost, when locking to certain cores, and some the other way around..
Afaik, its only usefull if you run it servers with multiple gpu with multiple cores, ive tested it a bit a while back and saw no difference in performance..

Ah cheers guys, I decided to turn it off since i didn't see a performance boost either.

I am using a dual core comp to fold on and i am using the cpu client that runs in your taskbar (so not the command version).

you can try and run it on for 5-10 mins and then see your projected performance with Fahmon (see sticky thread in folding)... then do the same with it off... That way you'll know for sure
