Hi all,

As above id like to OC my 3570k now that i've got my hyper 212 installed on my Gigabyte z77-d3h. Im only looking to go up to 4.1 maybe 4.3 but not too fussed as i dont really want the extra temps.

Can someone tell me what voltage/vcore i need to set for this please? I read on here somewhere that OC'ing to about 4.1 i wouldnt need to increase the voltage from 1.1 is that correct?

I think my board is set on auto voltage by default which i believe incurs the wrath of high temps (although unoticed at its default 3.4gh).

Do i just need to change the cpu clock ratio to say 41 therefore 4.1 and set the vcore to 1.1 or 1.2?

If someone in the know who has this board and cpu could impart some wisdom upon me i would be grateful :).

p.s. i found a tutoriol on youtube for a similar gigabyte board but he was doing it to 4.5 so wasnt sure on the voltage i need so here i am!

Thanks! :)

Hey Buddy, that is one very nice processor.

I got a i5 3570k with the same cooler, Hyper 212 Plus. I am super surprised at the kind of OC I can achieve with this thing.

I first OC to 4.2ghz and I just had to slighty bump the Vcore to get it stable. Max temps were about 60c at full load.

While gaming they were at around 40c-50c

This is what I would recommend:

Change the Multiplier to 41 which will make your CPU go to OC 4.1ghz

Leave everything else on Auto even the Vcore. Load Line Calibration change it to 1.

Boot up the computer and open CPU-Z, Core Temps and Real Temps.

Run Prime95 using the "Small Stress Test" (This will stress the CPU and go to maximum heat very fast, within the first minute it will be make the temp go up...

Run Prime95 using the "Small Stress Test" (This will stress the CPU and go to maximum heat very fast, within the first minute it will be make the temp go up faster than the blend test)

Go back to CPU-Z and take a look at the Vcore. This will give you a pretty good idea what your Vcore should be set to.

Restart PC, set your Vcore to offset and set it to whatever Vcore CPU-Z was showing and then stress for some time and see if it crashes.

Also open "Event Viewer" and look for the WHEA ERRORS. If you see any, it means that you are not stable yet even though the PC hasn't crash.

To see WHEA ERROR go to: Start>Control Panel>Administrative Tools>Event Viewer or just search for Event Viewer under Search.

Then go to Windows Logs>System. Here you will see the WHEA ERRORS. If you don't have one after a while then you are stable.

Hope that helps
