So to keep it short I got FX 6300 today and I am trying to OC it to 4.6 stable, I know my mobo isnt quite an overcloking tool to begin with, but I dont get something about this CPU. At 1.48 CPU voltage and at 4.6 Ghz on PI iterations I get this... out of 20 iterations one is with error, with message not exact in round, and that is the FIRST one out of 20. So what does it mean, is it maybe a ''mistake'' from the software or something's not right? I also get only 30 degrees celsius MAX when fully loading my CPU with games such as Far Cry 3 and/or BF3.(with Corsair H80) What to do, should I lover the clock's or am I doing something wrong?! EDIT: Yep it crashes, tried to lower it to 4.4 Ghz and also lowered the voltage to 1.46 still crashes. EDIT2: I started from scratch got stable 4.0 Ghz at 1.36 volts(default 1.33) that's an increase of 0.25 in BIOS, gonnay try to push it up further now at this voltage. I also set CPU NB voltage at + 0.175 and CPU NB is at 2600 mhz, stable. EDIT3: For 4.2 Ghz I had to raise volts from 1.33 to 1.41(+.50) in order to keep it stable, I think I am just realizing I am having tough luck with my CPU; it was just a bad ''draw''. Anyway I am going for 4.4 now... EDIT4: 4.4 stable at 1.48 volts, not going any higher, I will try to squeeze out 4.5 with 1.48, if it doesnt work I will stick with it as is... I guess I was right just bad luck out of the draw with this CPU, I was expecting much more. EDIT5: It turns out I may be without enough power as I only have a XFX 550Watt Bronze, and my GPU is sucking out around 366 Watt under full load when playing BF3, and my CPU when OC'd simply doesnt have enough juice, resulting in my PC getting restarted sometimes, and sometimes it just BSOD's or goes to black screen. I will still wait for final confirmation from the people I sent the private message to, since I am not keen in going out and wasting over 80$ just to find out it wasnt PSU -.- EDIT6: Problem solved, been playing BF3 for 5 minutes @4Ghz PC restarts! Set it back to default 3.5 Ghz been playing for over half an hour without a problem! I simply run out of power, so I am going to buy a 750Watt Corsair or Seasonic, might even go for XFX again. Anyway thanks to everyone for giving out they're tips and tricks FINAL EDIT: Changed my PSU to Corsair GS 800W series, I've been running out of power. 32M PI Iterations 0 errors, Futuremark CPU stress test 0 errors; need to test Prime95. Max temp. achieved was in BF3 38 degrees celsious with Corsair H80 water cooling. Prime 95, 12 hours run 46 degrees celsious, stable... CPU VCORE Voltage 1.52, 4.7 Ghz CPU clock, RAM DDR Voltage 1.55, Ram timings 8-8-8-24/2T, CPU NB frequency DEFAULT(any change CRASHES) 1.50-1.55 core voltage is safe according to AMD engineers Source it's mentioned in the third paragraph page 9.
