First time overclocker....

post #1 of 36

]This is my processor in prime95. It's a i5 3570k, -60v offset, havik 140...



Regular:



Will this is be okay as a permanent overclock for everyday?

Temps seem a little high for that speed/voltage/cooler, but it's certainly safe for everyday use.

Okay, I figured what I did wrong. I had the screws extremely loose on the Havik, which caused bad contact. Here's the updated after tightening the screws:

Extremely happy. Was worried for a second. smile.gif

Your temp looks great. I think you can push further from there.

Typical Sandy/Ivy bridge unlocked cpus allow 4.5GHz with moderate voltage that is safe and efficient enough for every day use.

Bumped it up to 4.4 just to try it. Had problems with it though, kept crashing. When I went to the suggested 4.4 overclock on my asrock board it finally booted successfully.

Regular:



Prime 95 (For about 15 minutes)




Feels stable. I know voltage is a bigger deal then temperature, but I'm really not sure how high the voltage can safely go... Does it look okay by these pictures? I was watching CPU-Z, I never saw Core Voltage hit 1.3 or above. So that's pretty stable for a permanent overclock correct?

I really don't think I'm comfortable running the overclock higher than 4.4 however

As long as your Prime95 stable for 12+ hours, your temps look pretty good and your voltage is reasonable, IMO. I think most IB chips are averaging 4.5GHz @ 1.250-1.300V or so. With that, you're in the same ball park. thumb.gif

The only thing that's jumping out at me, though, is your idle voltage. Both idle screen shots at 4.2 and 4.4 show the CPU still clocked high, but the vCore is much lower. I'm not sure if CPUz is being weird or something, but maybe check if Speed Step is functioning right. smile.gif

1.3V is perfectly fine, and most people would be completely comfortable up to 1.35V. So you are certainly good to go at 4.4 @1.28V. You'd probably be able to do 4.5 @ 1.3V or less with good temps, based on what you have now, but it's a pretty meaningless performance difference (although 4.5 sounds nicer).

Good catch on the idle clocks - make sure you have the Windows Power Plan set to Balanced also, High Performance keeps it from downclocking. The BIOS options to check are EIST, C1E, C3, and C3, but I'd guess it's the power plan.

For Ivy bridge, Intel recommended voltage is up to 1.325V(which means you can go beyond this by some margin safely). So you don't really have to worry about sub 1.3V voltage.

In most cases, limiting factor is temperature in Ivy bridge. So I would find a point where I can maintain sub 80 degree under full load. (Probably 4.5~4.6 at 1.3~1.32V)

I believe I have it on 5 in speed step.

Looking at it without prime95, I jumps from around 1.0v to 1.1v.

Yeah, I have it on high performance. Is that a problem?
