Hi!
I recently started trying to overclock again, since we are getting winter temps now.
I am no expert, therefor I would love you to help me!

First, my specs.
750w psu from xfx
I5 3570K
Corsair Hyper 212 evo
Asrock Z77 Extreme4

I have put my LLC on level 1, changed the All core ratio to 42, since I'm looking for a 4.2 ghz oc, and put my offset to -0.080. I don't really know what the offset does, but to get lower temps I would need an even lower offset, right?
My vcore is on 1.215 when using prime95.
I also read that your offset should have something to do with your vid, mine is 1.3 when stress testing. Using intel burn test on high for 2 minutes, all cores hit 80 which is probably bad.
Do I just have a really bad chip for overclocking, or am I doing something wrong?
Edit: when idle, my processor is at 1.6 ghz, it should go down, right?

Then go back to what you know works and slowly walk the voltages down. I might also make sure my Heatsink was installed well and would consider re pasting it if you didn't clean the old stuff off good before the new install, or fiddled with it much while installing it)

Offset is a difference between the VID and the actual voltage supplied to the processor. 80 is a bit warm, and is what I usually shoot for. Supposedly 90 is the limit, but I like to have a bit of a safety factor.

Your I5-3570K is using the same settings as mine, and mine hits 78 during a full 10-cycle run of Intel Burn Test. I personally would have expected yours to stay a bit cooler than mine, since you are using a 212 Evo as a cooler, while I am using a 212 Plus. Supposedly, the smoother base of the Evo is good for another couple of degrees lower than the Plus.

For the most part, lower voltage will yield lower temperatures. However, that's no good if the processor crashes if you so much as sneeze near your computer. Make sure it is stable first, then try lowering the voltage slightly.

Mine idles at 1.6 GHz as well.

I don't recall exactly what happened the last time I did it, but I'm pretty sure it crashed.
Also, when running intelburntest or prime, my hardware monitoring freezes and stops updating.

So, with my current settings I passed an intel burn test on high with 10 times to run. Highest temperature on any of the cores was 82.
Would I benefit from getting a closed loop watercooler, like the h80i?`
I'll try lowering my voltages.

Alright. I did as you advised me to, and lowering my offset to -0.095 let me complete the same intel burn test with the warmest core on 74, which for me seem wildly unrealistic. I don't think that is the correct max though, as I would expect a stress test to make the temps fluctuate constantly, which they definitely didn't.

I just completed a 10 times run again, hit 78 degrees now. I guess this my problem is solved now, thanks a lot :)
Do you by any chance have a solution to my hwmonitor problem, or isn't it suppposed to fluctuate much?

Alright. I tried running cinebench, and got really worried. My cpu has never been higher than 4.2 ghz, cinebench lists all of my results as 3.40 ghz, but running the cpu test, I got a score of 4.62, which is very low compared to the 6.91 result that is my record. I should raise the vcore, right?

I don't know I don't do much benchmark mess, I go by feel and fps, benchies and whatnot don't mean anything to me, if I get more fps in a situation than I used I did good, if it went down I undo what I did. If it feels "choppy" I change things till that goes away. Not trying to discount what you ran into or saying to leave it alone, but I prefer more "in use" kind of decisions.

Alright, I found out why and set a new all time record. I had closed all background processes and set the priority of Cinebench to high :) Thanks for your help!
