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.

ivy is one strange chip
4.2 stable on auto volts
4.3 requires 1.25
hate to think what 4.5 is gonna be like
My 3770K needs 1.285V for 4.5. Under water it stays at approx 70C accross all cores when running prime.

4.2ghz on a 3570k here, auto volts at 1.244 max temp of 62c. Should start manually clocking it tbh.

Cooler?

Alpenfohn k2 with it's stock supplied fans.

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.

Auto is not stock volts.

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.

Mine is:
4.4 requires 1.18V
4.5 requires 1.22V
4.6 requires 1.32V
4.7 requires 1.42V

i make 4.7ghz @ 1.28v

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.
