ASRock 970 PRO3 + FX-8350 + CPU Active Core Control

post #1 of 3
Thread Starter 
I currently have an ASRock 970 PRO3 motherboard which I am using for some single threaded performance tasks. However, I am interested in upgrading the CPU from an Athlon X2 270 to a more modern CPU, a FX-8350. If I recall, the IPC of the newer AMD Piledriver processors surpasses their K10 architecture.

The catch is, I am only wanting access to two cores in two different modules, aka disable two modules out right, and disabling one core each of the remaining two modules. This should yield two threads of maximum performance with dedicated FPUs each. Then, I might be able to overclock it significantly higher and focus on single threaded performance over having multiple threads I do not require.

My question is, does the "CPU Active Core Control" of the ASRock 970 PRO3 have this capability, or does it only disable full modules? Does anyone here have experience with clocking Bulldozer/Piledriver processors higher by disabling modules/cores?

I will, of course, be giving rep for helpful responses since it seems to be rather difficult to get on here...

It is not going to happen sir. You can only choose one.

One choice? Aka, I can either only disable whole modules or disable single cores within modules, but not both?

Sorry, I'm not 100% certain what you are referring to.

Oh, unless you are referring to only being to rep one post. If that's the case, my mistake, I am still learning some of the specifics here. I will then only rep the most helpful post after a few days of nonresponse.
