Anything that's Prime95 stable for 6+ hours and with safe temperatures.

Is 1.45 or 1.50v acceptable for load in 24/7 config?

As per the guide, acceptable is up to 1.52v 24/7.

With that said, no one can give you a definitive "perfect" answer. (No one has really tested each voltage level to see if it does harm.)

I have been running on 1.52v for over a year now and so that is what I recommend in the guide as a max.

I can tell you that 1.52v is REALLY pushing it though. Any higher, I think, would do harm. So if you feel like its too much, lower your personal max to whatever you like. Some like 1.45v, others like a measly 1.35v. Anything below 1.52v in my books though.

For those of you that pay your own electric bill, be mindful that you really hit a point of diminished returns when really volting these chips. On my old asus board, to get from 4.8 to 5.0 required going from 1.38 to 1.48v. That extra .10 volt doesnt sound like much, but watching my rigs wattage draw at full tilt jumped from the 340 watt range to the 420 watt range. It seemed crazy to me to give it 80 extra watts for a measley .2 ghz.

Ivy bridge and Extreme 3 Gen 3 Board
I've tried for hours and ended up with non stop BSODs

I went from LL2 to LL1, I felt that there were too much fluctuation
I dialed it in at a fix range of 1.36 volts and was stable, so then I offset +110v because my bios was giving me 1.20v

Now my question is about the temps. Are these too high ? I'm air cooling with a thermal right mux 120 and typhoon @ 1100 rpms, along with 3 other fans my case

188
I apologize, for the hard to read screen print. I'm not sure how to do it with double screens

Just a quick update
I tried to go up to 4.8 but this ivy bridge would not hear of it. I had to increase the offset up to +.150 which brought me to a Vcore of 1.416v
But nothing I could seem to do would reduce the temps, so I went back down to 4.7 @ 1.36v at as I mentioned earlier
Almost had it

Yeah I am in the same boat, I can do 4.7 @ 1.37v, 4.8 is out of the picture, 3D transistors just hate that high voltage man frown.gif
I think Ill just use 4.5 @ 1.27 for my day to day, 200Mhz definitely not worth 0.1 extra volts right ?

I got a Asrock z77 extreme4 with 3570k along with Cooler Master Hyper 212 Plus.

I shouldn't have any problems overclocking to 4.5 and keeping it for daily use right.
