Okay, I'm not sure if my overclock is entirely stable. Is it?

post #1 of 21
Thread Starter 
So I ran 25 runs of Intel Burn Test (yes, its good for AMD also) on very high and on the ninth test it failed. So I went back into the bios and bumped my voltage up one notch to 1.3125 (CPU-Z says my core voltage right now is 1.328 for some reason). After I bumped the voltage up one notch from 1.3000 to 1.3125 in the bios I ran another 25 run Intel Burn test and it succeeded.

However, I noticed that every time my temperature went to about 61 degrees C, the CPU throttled itself from 4.1 ghz to about 1.4 ghz and the voltage throttled from 1.35-1.36 (I have it set to 1.3125) to 0.8 v. Then the speed and voltage rebound quickly to 4.1 ghz and about 1.35-1.36 v. Is that normal or is it slightly unstable?

I'm on an FX-6300 and its overclocked to 4.1 ghz, my motherboard is an ASRock 970 Extreme3 and my CPU cooler is a Cooler Master Hyper 212 EVO.

How long is 25 passes? I would say you want to stress test for 24hrs

Well apparently for Intel Burn Test that isn't necessary, apparently passing 20 passes is stable, I went with 25 runs just to be sure.

I'd try prime95 too if you really want to know if its stable probably isn't needed but then again was the post if you weren't concerned

d00d..If it passes 3 runs of IBT it most likely will never crash.
Even the maker of IBT says he wouldn't do more than 3 runs.

As for the throttling issue, do you have the turbo, C1E and the usual suspects turned off in the bios?

I had that same cpu and motherboard. Your vrm's are over heating causing the cpu to throttle. Slap a fan over them and you should be good.

Everytime I tried to clock past 4.3 they would throttle the cpu. I put a cpu fan directly above them and was able to hit 4.7ghz.

Thank me later thumb.gif

Well, I did 25 runs on standard stress level just to be safe.

Yeah, I have them disabled, but it might be hte VRM overheating like Dimaggio1103 suggested.

Huh, that might be it, I heard my VRM got really hot, but of course not hot enough to catch fire. Is there a guide on how to put a fan over it? I still have the fan from my stock CPU.

Also, I should mention that for some reason the cursor in Counter Strike Global Offensive's main menu is laggy for some reason, the game still runs fine though.

I don't throttle in game though so that's good.

I have that problem with Cs too. No idea why. Did it on my phenom 2,8350, and 6300 while overclocking. Perhaps Nb, I don't know. Doesn't do it now but I just installed Windows 8.
You should be able to mount the stock heatsink fan over the Vrm somehow. Also that many runs of ibt is way overkill in my opinion, but it's up to you. One run of very high is enough for me personally for me to call it stable. 24 hours of prime is entirely too much in my opinion but again whatever you're comfortable with.
