3570k OC question..

post #1 of 7
Thread Starter 
So I'm using a 3570k on an ASRock Extreme6 Z77 mobo. have a Corsair HX750 powering it all, and I tried my hand at OCing it over the last couple days. I was able to get a partially stable OC to 4.7 on about 1.275v but no more. I say partially because it would boot and everything but would crash on the Prime95 testing(blend, max of CPU and RAM testing). I tried cranking up the volts to about 1.325 to achieve even just a boot on the 4.8 but couldn't seem to reach anything even remotely stable(bluescreens, bootloops, freezing, etc). The ONLY things I did was change the vcore and the multiplier. Funny thing is it's perfectly stable on 1.200v up to about 4.4(4.5 was kinda iffy on prime at 1.2v). Is my chip just an average batch or is it just being temperamental forcing me to mess with the PLL and other settings? Still new at the overclocking so any help is appreciated! btw, everything was left at factory besides the two things mentioned. Rig is aircooled only, and so far has not broke 84ºc(peak under prime) even at 1.325v. Was going to reseat the Havik 140 to drop temps a few degrees(I already know it wasn't seated the best)

anything above 4.6ghz I need to enable pll overvoltage, and I have pll voltage set to 1.7 try those two things first and see if that stabilizes your clock and then report back. For higher clocks you often have to change more than 2 settings

Thanks! I wasn't expecting much out of only adjusting those two, but it got me decently far, imo. I'll get to that tomorrow. For now, sleep and a fresh mind to start working on it!

your welcome it shouldn't be much longer to get it stable those two setting come it to play much more when getting into the higher clocks, but there are other tweaks as well. such as setting cpu fixed frequency to 350 setting phase control to optimized or extreme/full, disable spread spectrum. take a stab at those later.

Sorry for the delay in getting back. With the OC I attempted, the bios already had the PLL overvoltage enabled, plus is set to auto pll voltage but is currently at 1.832v. I didn't realize these were enabled from the factory. shouldn't I have to drop the PLL voltage to assist the OC with the 3570k(typically)? I had read through the various overclocking guides for the IB chips a while back but haven't had any time to really do much other than tweak a couple things and call it a night(been super busy with work and family)

necro I had better luck on my asrock extreme4 z77 mobo using offset voltage but the lowest amount over zero so +0.005 andn then increase cou vcore using "additional turbo voltage".

I got stability using this, where the same amount of vcore had failed on offset and manual voltages. The only issue with this is that cpuz does NOT report correct amount of vcore, and in actual fact the actual vcore on your chip is around +0.05v more than what cpuz is reporting. So if cpuz says it only using 1.35v, its actually closer to 1.40v.

Also contrary to what other said I didnt need to change any other settings other than cpu vcore, dram volt. No need to stat changing stuff like pll voltage, VCCIO etc.

If you think you might be struggling because of the c3/c6 states (power saving feature) settings, try have a look at this guide here - http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition

Thanks for this! I have been extremely busy lately and have not had any time to try to mess with it. $ilent, I originally used that guide to prep myself for the OC, but I couldn't seem to find anything that wasn't already preset by the bios when I started the OC.. I'll try it all again from the beginning and see what I can get and get back when I actually get time to mess with it(family and work have been highest priority lately). Thanks all for the help with this and I hope it gives me some better luck!
