Disabling Cores to reduce TDP?

So I made a silly oversight and bought a CPU without checking my MoBo's supported max TDP. As it transpired the board, ASUS, is 95w max and the CPU (FX8350) is 125w.

While I'm waiting on the new MoBo to be delivered I'd still like to be able to play games and such. Are each of the cores weighted equally and would disabling the 7th and 8th cores and running it as a Hexacore reduce any instability until I get to upgrade my Mobo or would I be better reducing voltage?

Yes, disabling cores will work. Use this to help http://www.cpuid.com/softwares/hwmonitor.html

You would probably want to take it down to about 4 cores for safer measures

If you can boot into BIOS, and disable two of the cores, maybe under-clock the cpu too. The PC may run fine and stable even it only run 6-cores. But if the pc will not boot into the BIOS, you have to wait for the new MB.

Thanks guys. Yeah the Bios boots. I was playing DayZ on it yesterday with the cores slightly underclocked and as a quad core just to be safe. Just wanted to double check and see what the max I can safely get out of it is :)

Idk for sure. Thats what the cpuid program is for, I bleive it tells you all about your indavidual cores and how much wattage they all use so you'll know how many to disable. I got that from a nother forum but I have never used it myself http://www.cpuid.com/softwares/hwmonitor.html

Cheers!
