[HELP] why my FX6300 dont perform well?

Have you kept track of your temps during prime95? While it may be stable, it could still be throttling down from heat.

Have you tried to back it down a bit and see what your scores are? Really a FX runs best with a 990 FX board and higher memory such as 1600 or 1866 Your board is fine for what its doing and accepting your chip but how does it play ? games.... If it plays fine don't worry so much about the bench marks No 2 chips are the same alike period some guy example A GETS 5 ghz out of the chip while guy B only can get 4.1 Ghz out of the same chip.... Whats your ram speed? do you have proper cooling maybe the chip is getting hot throttling ....

This is from toms a guide to help you

Not to sure over the Bulldozer series, But my Phenom II x6 1100T can't have any of them power save options on, CnQ is about and the system will still boot but not stable during idle, but perfectly stable during loud. This was on 3 mobo's I have tested so far.

Either way, These settings might help you, These is what I look for with OCing

1* Disable Auto Vcore, set manual Vcore to 1.4v
2* Adjust LLC (Load Line Calibration)
3* Disable Auto Fan and turn it to max (For stress testing if you have no software to control fans)
4* Disable CnQ (Some mobos/CPU don't like it, disable for now and turn it on later)
5* Disable C1E Power save
6* Disable Spread spectrum (Always disable, even if not OCing)
7* Turn off Turbo core (OC to the Turbo frequency that way all core are at turbo speeds)
8* HTT keep near 2000mhz (Some programs of mine actually improved with it at 2400mhz)
9* Set CPU-NB to near 3000mhz (Again this is for the Phenom II, not sure how the FX will perform with a higher CPU-NB)
10* Set CPU-NB Voltage to 1.3v (Thats if you OC it, don't add volts if you didn't OC it)
11* Add a bit more volts to the RAM (1.55 is my ram, I have it set to 1.6v, Helps with stabilizing an OC at times with a high CPU-NB)
12* Stress test, WATCH TEMPS!!!! (The max safe temp on that is 62c, So keep it below that during full load and all should be fine.

I use Prime95 and test for a few hours, and use core temp to shut down the PC if Im not watching and the temps get outta control, but core temps are kinda funny at times, mine are always 13c off from the CPU temp.

Now If I were you, I would only OC the CPU for now, with the multi, Disable any power save settings and set the volts accordingly for the CPU only, Then once everything is stable and in control, OC the CPU-NB and its Volts and test again. 20 Min test with Prime95 is good for in between tweaking, But for long term, test for a 3 - 4 hours or more. A bad CPU-NB can cause BSOD or a error on a core and Prime95 with stop a worker on that core that got the error, means raise the Voltage on the CPU-

hope this helps

save your current profile, write down the settings, take a pic, whatever make sure you remember the settings youre at right now.
Now thats done, go back to stock, and reboot. Run cinebench write down your results at stock etc.
then follow this guide, and read it all through a couple times its pretty heavy..can be a lot to digest at first. Im confident this will solve any things youve missed on the way...
Are you sure youre using Cinebench R15? 64 bit version?...my cinebench looks like this.
