FX-6300 overclock

post #1 of 8
Thread Starter 
I have been experimenting with my FX-6300 to overclock it a little bit. I'm now at 3.8 ghz with 1.35 CPU voltage. Because i don't have a good aftermarket cpu cooler yet, i am limited to overclock my cpu. But when i test my cpu with prime95 i get: 'FATAL ERROR: Rounding was 0.5, expected less than 0.4 Hardware failure detected, consult stress .txt file' should i be worried? When i tested it before it didn't gave me that error. I got a lock up during a game so i decided to test it again, and now 2 of 6 workers fails. My temp are around 60° during tests with prime95. What should i do?

I overclocked my CPU by increasing my bus freq. which is now 217 instead of 200.

Specs:

Motherboard: Asus M5A97 EVO R2.0
PSU: ModXStream Pro 700W
CPU: FX-6300 3.5 ghz
RAM: G.Skill 8 GB (2x 4gb) DDR3-1600 Kit, F3-12800CL9D-8GBXL, RipjawsX
Graphics card: ASUS GTX660 DirectCU II TOP


EDIT: I only get this error when i'm doing a blend test ( test of everything, lots of RAM test) and not when i'm doing a regular small fft's test (RAM not tested much). So the problem is probably my RAM.

The 6300 runs at a stock turbo of 4.2Ghz, just turn turbo on and undo your OC. Or set 1.45v for 22.5x multi and walk your way down the voltages

When you over clock the FSB you also overclock the RAM, NB and HT. HT should be fine up to 2600 but NB may need a voltage bump to get it stable it doesnt like going above 2400. Have mine stable at 4.6 214 X 21.5 @ 1.45V, gets power hungry there. uses less at 4.5 210 X 21.5 @ 1.4375V

Just don't overclock using the FSB. The multiplier was invented to make overclocking easier XD

Also I don't know if it is true or not, but I have heard lots of stories about Prime 95 failing overclocks on Piledrivers that passed Intel Burn Test and OCCT. So if you can pass 20 runs of Intel Burn Test on maximum and a few hours of OCCT but still fail Prime, I would call it stable.

Ok thanks a lot. One more question: To raise raise my nb voltage do i need to adjust my cpu/nb voltage or just nb voltage? What's the difference between them?
post #6 of 8
The NB voltage is on the MB, the CPu NB voltage is onboard the CPU. What are you increasing, NB or CPU NB?

hello,
no need to mess with the nb or the cpu nb, just lock there voltages to recommended.

If he is raising the FSB he will need to adjust teh NB voltage or it will be unstable. The HT Voltage is fine and will work quiet happily to 2600, but NB need to be tweaked. Will have to see which one it is.
