3570k @ 4.2 temps okay?

Baygamer415 · Jul 7, 2013

i set my OC to the 4.2ghz optimizted OC that my Asrock z77 itx board has set on there just to see what the Voltage it sets it to.
ran prime95 for 10 minutes and my temps were 63, 67, 69, 66 @ 1.24v with h100i?? I think they're somewhat high and possibly voltage may be high.. what do you guys think?

With an H100i you shouldn't be going over 60 degrees at 4.2GHz, at 4.4GHz with a Hyper 212+ in push/pull I barely get to 62 on any of the cores after 10 minutes. Your voltage is a little high. I would overclock manually at stock voltage and compare the temps, I got mine to hit 4.4GHz within 45 minutes (including some testing) at stock voltage, it's not very hard.

Try knocking down the voltage a little bit.

Also, with my h100i I'm getting idle temps at 3.4 from 26-32c..i've been re-setting my block and even got the washers to make the stand offs more sturdy but I just cant get my temps down at all. Any ideas?

I watched the vids you made, temps aren't bad , but maybe a tad high.

Baygamer415 · Jul 7, 2013

I didn't make those just followed what they did... ok i currently when down to 1.195. I read an Ivy Bridge overclocking article somebody made, he was mentioning to decrease the PLL?

Those idle temps are completely fine as the CPU is downclocking when not in use. I used this guide when I learned how to overclock on Ivybridge, then I tested with small FFT in prime95, you shouldn't have too much difficulty if you reset your settings and try overclocking at stock voltage before increasing the voltage, only add power when you need stability basically. Here's the guide: http://www.overclock.net/t/1247413/ivy-bridge-overclocking-guide-with-ln2-guide-at-the-end

You can also refer to here for an "Asrock guide" specific to a board similar to yours: http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition

currently at 4.2 @ 1.152v and top out on my hottest core at 62c.. only did a brief prime95 test (will do longer one tonight).. those temps look okay or where they should be? Do you think I can go lower on voltage at some point?

mclovits · Jul 7, 2013

Baygamer415 :

Well, that is a lot better than before, less strain on the CPU at that voltage. I would test for stability and save those settings/write them down. Have you tried overclocking at just stock voltage though? I'm telling you it might be worth a shot to try, you might be surprised at what your CPU can do, and again, those guides are super helpful.

Yeah i tried OC at stock voltages... Stock would be on "auto" correct? If it is auto then at 3.4ghz sotck voltages was really close to 1.2 or high 1.1___. I am offsetting my voltages by .090 and i get 1.152v

Hmm, mine never goes nearly that high, that's odd, I guess the chips are going to perform differently. you're looking pretty good if your temps are staying around 60 with your overclock. Maybe try reaching 4.4 or 4.5 GHz while you are at it considering you have such a capable cooler.

waiit sorry my stock is 1.040v @ 3.4ghz at 100% load... I was looking at a different voltage i had written down.. so from 1.040 how should I gauge increasing voltages? Offset +.05 or should I keep turning down from 1.152 (where i'm at now)

That sounds more realistic, Don't worry aout lowering the voltage from where it's at now, start raising the CPU multiplier a bit and raise your clockspeeds to around 4.4 or 4.5GHz, test for stability. If you are not stable there then maybe add .05 to the offset and try again. 4.2GHz is a modest overclock but now that you are stable (from what I understand) you can start ramping up the clocks a bit, don't worry, your cooler is more than capable of a 4.6-4.7GHz overclock, though a more modest one is more practical.

right on man.. thanks for the help. I'll keep you posted on how it goes.

Sure thing, sounds good.
