I'm building my new rig this weekend.... 3770k + evga 680 4mb + lga + Asus P8Z77-V

 

Trying to do my homework first, I noticed that with the Asus Mobo it is very easy to Overclock certain cores of the CPU and not others. Since I will set FSX to use Cores 0 + 1, I was wondering if there is any major advantage in Overclocking just those two cores and not the others, the idea being to keep overall temps down to acheive a higher overclock. I'm going to start out using the Cooler Master Hyper 212 EVO in push pull.... Any help or advice would be appreciated since I am kind of new at this.

I'm not sure I understand this correctly. Are you planning on disabling 2 cores? FSX will never the less make good use of all your 4 cores.

3770k (...) Since I will set FSX to use Cores 0 + 1

 

First, when are you talking about core0 and core1, do you think about real cores (HT disabled) or real and virtual cores (HT enabled)? For FSX is recomended to disable HT and use all 4 real cores for FSX. Depending scenery type FSX can easily use 4 real cores or even more. First core (core0) is responsible of main FSX's thread processing and next three (core1, core2, core3) are loading and processing DEM (mesh), textures and autogen.

 

Second, why are you planning to allow FSX use only one real core (if you won't disable HT) or two cores (while HT will be disabled)? It seems to be bad idea.

On my notebook I generally use Taskmanager to adjust Affinity for the cores I want dis- or enabled.

 

Disabling core 0 works better in FSX with an i7 920XM CPU, temps not so insanely high as on full blast.
