Hi! I would like to OC my CPU to 4.5ghz. My specs are the ff:

CPU Amd fx-6300 @3.5ghz
Mobo - Asus M5A99FX PRO R2.0
Memory - Corsair Vengeance 8gb 1866
GPU - Sapphire HD 7770 1ghz
HDD - 1 TB Seagate
PSU - CX500 (500W)
Cooler - Cooler Master Hyper TX3 Evo
Fan - 4 x 120mm AF series Corsair

I've tried doing this on my own but it always HANG after 10 secs of Prime95 in full stress test.

Any suggestions?

did you up the voltage?

Almost impossible to get in air cooling with an AMD CPU.

I suggest you start for disable the Turbo Core option in you BIOS. Set all to defaults settings and start to rise multiplier with the stock voltage, test the stability at 3.8GHz wir prime95, OCCT or y-cruncher for more that 2 hours. Always check the temps, aboce 55°C isn't good.

What temps are you getting on idle and load with that cooler at stock settings?

Your board has 6+2 power phase so 4.4-4.5GHz with a good air cooler is doable.

Some of my notes from another recent post on an FX 6300 OC:

"...
To counter voltage/clock fluctuation due to features, disable:
AMD APM (Application power management)
C1E
C6
Cool and Quiet
Virtualization
Spread Spectrum
Core Boost

To counter instability due to FSB and IMC, give your HT and CPU NB voltage about a .050v boost. Should be around 1.150 and 1.250 for these.

To counter instability due to v-droop, if you have LLC calibration set that up to it's highest setting, usually in the 2.5-2.7v range.

These should help.

I was able to get my brother's FX 6300 to 4.4GHz @ 1.375-1.40v core using the above NB and HT voltage bumps, and also supporting DDR3 1866 at 1.520v DRAM. NB was 2200, HT was 2400. With the Hyper 212 EVO is stays in the 52-55c range under full load.

Worth noting: That is BELOW the stock core boost voltage of 1.425v. We got a REALLY good chip for his system, it clocks like a champ. Hope you have similar success...."


In addition, the FX series CPUs have a higher safe temp and voltage than previous generations. However, AMD has been reluctant to make any official statements on the threshold. A FULL LOAD temp under 58-60c during your OC stress tests is OK, since real-world temps will be much lower. You want to see the daily use temps in the 50-55c range or lower.

I think it's your cheap PSU issue.

MSI 970a-g46
amd fx 6300
8gb g skill at 1866
zalman 7500 cpu fan

my cpu is overclocked to 4.5 ghz at 1.45v ranges from 1.448, 1.56, 1.64v in cpuz max temp was 61c which is totally safe. these can handle up to 75c to 80c. my cpu-nb voltage is 1.29 cause my RAM is oc'd to 1866 valley benchmark went from 51 to 64 avg fps

That PSU is a Corsair brand series, it's not a cheap PSU.

What settings are you using on BIOS for the overclock?
