***Official Ivybridge Overclock Thread***

Does disabling EIST and all the works help with stability?

No real interest in running with them on but my 4.6 Ghz with 680 SLI is proving a dog to get stable. No problems running it stable around 1.28V with SLI disabled.
 
Does this seem OK temp wise?

i5-3570K @ 4.2GHz, stock volts (auto), cooler is an Arctic Cooling Freezer i30.

Ran Prime95 for 25min, Small FFTs.

Im hoping i can get the temps a bit lower once i start clocking properly. The k2 is a great cooler, if a bit on the big side though.

Yep, up near the north antrim coast here.:)

I'm way to lazy to do manual OC. Happy with 4.2GHz @ stock volts. Stays below 70c so I'm happy. :)

I'm using a P8Z68-V LX, so not the best for OC anyway.

still by far the best stability program for my Ivy is Handbrake

if it can complete a few encodes in handbrake (so 6 hours plus) without Handbrake crashing out or any WHEA errors - then its a good sign

its the hardest program I find to get totally stable, it uses AVX I think so works the processor very hard (I get pretty high temps with it)

Video encoding is indeed a very good guide to Ivy and is less synthetic than many so called stability tests but again I would do a couple of passes and just use your system. The best guide of whether its stable for your uses is simply use it!!! and forgot un-natural synthetic demands on the silicon all together.
 
Is 4.2ghz at 1.24v any good? I just used some auto stuff in the BIOS. Temps don't go above 70 in prime and stay at around 55c during gaming.

i5 3570k+ mobo in sig.

Also just on an auto 4.2 oc, 1.244v. Temps at 62c max in prime, mid 50's in game. 3570k on an Asus p8 z77 v pro.

Cheers mate, just out of curiosity, where are you getting your voltage readings from?

I have CPU Z open and it is giving me a different reading than Coretemp.

CPU Z says 1.19v and Coretemp says 1.24v, which one is more reliable?

Thanks.

edit. Got confused with VID and core voltage. So my core voltage is actually 1.19v.

I was reading from CPU-Z, ill fire up prime and check the readings in both CPU-Z and coretemp.

At idle im getting the following.

CPU-Z, 1.072
Coretemp, 0.9457

Prime running

CPU-Z, 1.232
Coretemp, 1.2510

Bit lower under CPU-Z than i posted above, just remembered that i tweaked the oc settings a few days ago and lowered the clockspeed a little. Reading at 4223mhz.
