I've found a happy place with mine:

4.7ghz @ 1.3v (CPU input voltage 1.9v) temps are excellent, hovering around 50c when gaming with an EK Predator 360, even stress tests struggle to get the cores and package above 70c.
I've got the cache/uncore at 4ghz 1.25v
Corsair Dominator Platinum's at 2400mhz 10-12-12-28-1T 1.35v

I could probably push for 4.8ghz at 1.35v but I don't feel the need to keep going, there seems to be a big difference between the initial 5820k's and the newer ones, I don't know if OC socket motherboards have helped but after initial release many people were only getting 4.2-4.4ghz out of theirs.

Yeah the EK Predator 360 definitely has more to it than your standard AIO, all the parts are what you would expect in a custom loop, the quick disconnect is medical grade and one of the more expensive ones (found this out in Linus' review as people had commented it looks cheap and nasty), some reviews always surprise me when they have smaller and weaker pump AIO's ahead of it somehow, I really doubt my H110 would have kept it this cool.
 
I'll post my batch number tonight and post what clock I can acheive under the "safe" voltages of 1.35v core and 1.95v CPU input.

Shame it isn't stable :p

4.8 works fine and will bench fine but 4.9 crashes as soon as I start a benchmark.
 
Yeah 4.8 wasn't stable in the end for me even at 1.35v, ran stress tests fine but would blue screen after a while.

My wall seems to be 4.7, anything past that requires an insane voltage bump and just isn't worth it. Anyone running one of these at 4.8 and above rock solid stable must be in the top 1% of chips.

I know the american site silicon lottery that sells cherry picked CPU's have said only something like 11% of the 5820k's they've tested will do 4.7, so I'm happy being in that percentage :D
 
Well 4.7 is failing stress tests now for some reason, ever since I tried pushing it, I've reset CMOS and used the exact same settings I had before but I get an instability detected error on ASUS realbench during the handbrake test.

Previously it would run for hours fine, probably damaged the CPU lol. Come to think of it after setting everything back to auto I got a bios warning on reboot saying CPU overvoltage and for some reason it was at 1.5v for a few seconds, that's probably what did it, thanks ASUS :rolleyes:

Temps are fine for stress testing, <80c is good for stress tests.

If you're happy with 4.5 I'd leave it at that or you can try manually lowering the voltage and see if it will do 4.5 at lower volts.
