Cannot get a decent stable overclock on my fx 6300 with Asus board...

post #1 of 4
Thread Starter 
Hi, I've been running my fx 6300 unstable at 4.2 ghz with no increased vcore. I finally decided to do some research and min/max the potential of the CPU, but no matter what I do I cannot seem to get a stable overclock. I'm using an Asus M5A99X EVO motherboard and G.Skill ram (F3-1600C9D-16GXM). I've tried just about everything I've read on the forum: turning off power saving features (never saw a difference in stability and prefer to have them on anyway), different voltages/frequences for NB and FST (although I've seen it mentioned that it doesn't matter for fx), and finally different multiplier/FSB combinations to reach my goal of 4.8 ghz.

The highest overclock that I've gotten that seemed stable (until failing after around an hour in OCCT) was 4.7 ghz with around 1.52 vcore volts. No matter how many volts I crank it up, it doesn't seem to make a difference. Does anyone have some advice?

edit: FYI, I use extreme LCC, optimized Power Phase, Offset voltage

Extreme LCC definitely seems to help as I wouldn't be able to even boot into windows without it.

What's your cooling?

I suspect you're overheating. Toms Hardware says 5.0ghz with +10% Vcore and only multiplier changes, with a good cooler.

I have Phanteks- PH-TC14PE. My temps have never gotten higher than 60 C in OCCT.

Finally found something stable at 4.6 ghz 1.5v vcore. Ran in OCCT for an hour. Still not good enough though. The voltage is way higher than what I've seen people need.

We are on the same boat. I have the same CPU and mobo plus custom water cooling. The best I could achieve with this combination is 4.6 Ghz. at 1.5V. Much worse than most people report on the web. I was hoping to reach something like 4.8-5.0 Ghz.
I don't think that it is primarily a mobo issue. This chip needs a lot of voltage once past 4.4 GHz. and gets really hot. I get around 65C socket temp in Intel Burn Test and 63C in Prime 95 Blend (ambient 22C).
VRM and NB heatsinks get too hot to touch though. I am thinking this could easily hamper stability. I have already replaced the stock thermal paste of the heatsinks with a quality one before installing the mobo. I am surprised to find that did not help much. I will attach a side fan to my Corsair 600T in order to blow on theheatsinks and see what happens.
