I build a System with the FX-6300 on an ASRock 970 Extreme4 Board and I'm running Windows 7 64 bit.
On the Windows 7 performance index I get a CPU score of 7.4 - whereas the score of graphics and RAM is on 7.8.
On 3DMark 11 I get an Psysics score (which I assume is an indicator for the performance of the CPU) of 5353.
So, is my FX-6300 underperforming? Forgot I some important settings in the BIOS or in Windows? I installed the Bulldozer patches KB2645594 and KB2646060. I enabled and disabled the AMD Turbo Mode, I enabled and disabled C6 state - and no big difference (I got the best result without AMD Turbo).
I'm currently downloading 3DMark 11 to test my FX-6100, will edit this post in a few minutes with the results, let's compare.. lol
In my Windows performance index my FX-6100 is rated 7.3 on stock settings, Corsair 8Gb kit dual channel is 7.5..
