Intel i5 3570k Overclocking opinion

post #1 of 7
Thread Starter 
So specs:

Intel i5 3570k
ASRock Z77 Extreme4
2x8gb DDR3 1600mhz (16gb total)
Corsair H100i for cooling

This is my first true ever manual overclock on a cpu. I see people posting pictures and what not of what seems to be lower voltages used for the same clock, and some saying they need much higher. So I'm unsure if I have a great chip, a normal chip, or a crappy chip.

Right now, I'm at 1.21-1.22 voltage under full load for a 4.4ghz OC. I have an offset of -0.010 at the moment

My temps are staying in 60's. Does this look good, great, crappy, normal? Do you think I can take higher for 24/7 use? I'd like a 4.5ghz or 4.6ghz but I'm unsure exactly on my temps, plus max voltage I should do, etc.. Been reading, watching youtube videos, more reading, comparing to other's posts. Figured I'd ask and get some opinions. (I ran Prime95 for about 4-5 hours at these current settings with no errors btw.



Thanks for your help, opinions, and comments.

Also, I realize that if you look at that screen shot, it shows I just started the prime95 test and I said I ran it for nearly 5 hours. That's because I cancelled the test... but then restarted it to put the cpu under load to show you voltage and temps.

I'd say you're shaping up with a decent overclock. Most get around 4.5 GHz with 1.25 V...so it looks like you're about average. 5 hours of Prime95 is OK, but it's better to get a good solid 12+ hours in there. At this point you're probably at or very close to your stable voltage - worst case is you might have to notch up the voltage just a tiny bit if you failed Prime95.

Your temps are pretty good...the max on the warmest core shows 70°C which gives you some good head room. Most people prefer to stay below 85°C. However, it looks like you're running a Blend test with Prime95 judging by the FFT length. Personally, I like to run small FFT's (8k-16k or so) using almost all RAM as this pushes the CPU a bit more (and temps will be a bit warmer) - think of it as a worst case scenario. Also, if you find your temps are getting warm, don't forget you can adjust the fan profiles with your H100i with the Corsair Link software. When running something like Prime95, you can always set the fans to "Performance". It'll be louder, but you'll get more cooling from it. thumb.gif

Regarding your voltage, you're looking quite good here. When I was reading up on overclocking IB, there seemed to be some conflicting information on what the max voltage should be...some say 1.500 V (Intel Spec'd max) is fine, others prefer to keep it a bit lower (say 1.350 V max). Personally, I decided to play things a bit safer and keep under 1.350 V but that's just me.

TBH, if you want to push things a bit more, you've still got some head room IMO. smile.gif

Are you using Additional Turbo voltage w/ Offset or is it set to Auto? What is you idle voltage in CPU-z w/ a 16 multiplier?

What CPU cooler are you using?

be aware OP that your motherboard doesnt report cpu vcore correctly...and that 1.25v for instance will actually be 1.300v.

only way to no for sure is to get a voltage meter.
ive owned the extreme 4 and although the voltage was not exact .... it was darn close within .010v

With a DMM?

Mine was miles off...my 3770k was supposed to be 5ghz stable at 1.36v...yeah right only just 4.9ghz stable at 1.404v.
