You can trim it if you want but leaving it all on auto it works fine. If you want to run less you will need to turn the multiplier down from 37 to 36 but 4.625 doesn't seem to be an issue for anyone 24/7 with a decent cooler.

Auto is Evil and I don't suggest it. For 4.3GHz my board applies 1.45v automatically when the chip will do it stock. Auto is to be Avoided at all cost IMO

Nothing is wrong. You just can't trust Auto settings. And the RIVE over reacts more than alot of MB's when using Auto settings in the name of stability for quick and dirty OC's. It's a ROG board. Ive never had one that didn't work this way.

What's the max temp that this CPU shouldn't go over? Also is the latest real temp (3.70) accurate? Since my temps seem to be around 25c idle which seems a bit low.

At stock idle with a h100 and noctura paste I idled around 22-25*. Once I bumped up the oc it went to 29*-32 at idle. I also need to clean some of case filters though.

I think i've found my "daily driver" settings. I'm pretty happy with the CPU O/C, the under-volting, and the speed on my GTX580 also. This is all stable using F@H 24-7 thumb.gif
The Temps are with my W/C setup on the lowest fan speed settings with only 2 fans pulling into the lower 240 and 3 fans pulling out of the upper 360. Other stock case fans are just running off the mobo headers.

Just got mine put together yesterday. Using an ASRock extreme 4. Going from an E8500 to this, so OC'ing seems a little different (and easier!). Hopefully I got it right.

This is the first run of the burn test that completed. I think I'm around 1.35 or 1.38V, using 125 x 37. All other voltages are untouched. Speedstep and thermal thingy are off, but I'm not sure what else I should turn on/off.

It seems stable? I will just be gaming on this machine, so I'm not sure what "good enough" would be in terms of stability checks. This should be a good enough speed for me, and the temps maxed out around 80C with Prime95 Blend. My one concern is those two 9.x times in the burn test screenshot. Does that matter at all? Seems like I have plenty of headroom for more voltage, but I would like to see if this is fully stable first. Anyways, any tips would be appreciated, especially any other voltage settings I could adjust.

When i passed my first intel Burn Test, with 1.20 it was fine with 1024 mb, but cashed with 4000mb.

i think the minimun stability test need to be IntelBurnTest (or linx) with very high memory (around 4000)

Prime95 blend can run for 6 ot 7 hoursand then crash (need to be tested with FTT 1344 & 1792 for 25 minutes each)

and of course, 3dmark11 & vantaje to check LOAD +12v line from PSU

Pman1088 your values are very similar to me wink.gif. Rampage Formula IV is stable like a rock

Also need to set the thread count to 8, if HT is on & threads set to all, IBT will only stress at 50% load.
