Overclocking expectation on a 6700k?

Hi all,

Quick question:

I've squeezed well enough the X99 setup in sig and was thinking of selling the CPU/MoBo combo and grab a 6700k, just for the fun of it.

What kind of OC do those chips do under water? I know it's a lot about silicon lottery, but what would be the average clocker?

Cheers!

Certainly not more than what you have already... 4.5-4.7GHz I would say is a high average. Look around the forum and see. Plenty have asked about it/are overclocking them so you can check there while you wait for more answers. :)

4.85GHz 5820K @ 1.33V is incredibly solid. I wouldn't sell that for a 6700K.

Yes, I guess I got lucky on this one. Got it a couple of months ago, and, lurking around various forums, it seems the last Haswell-E batches do clock better than before.

Thanks, I will stick to my current setup (including the golden 780ti!) until Zen/Vega/1080ti.

Somewhere around 4.5GHz is pretty typical with an average chip and normal cooling, maybe more if you get a good chip.

Thanks, I checked your link (did not know about them...): these guys push quite a lot of volts in their CPUs! 1.424v on a Skylake? How safe is that ?!? :-/

Hijacking my own thread... How much vCore do you think I can put into the 5820K?
I keep on seeing around that 1.35/1.36v is max for 24/7 oc (i pushed well above 1.5v for a few suicide runs, though...).

You have already won the silicon lottery!:D

Why you would want to change to another solution set is nonsensical.:mad:

They push to what I consider 24/7 ambient limits typically, 1.424V on Skylake is fine, I'm comfortable at 1.45V for my daily.
FYI, I've bought CPU's from Silicon Lottery more than once, they're true to their word.

I trust you on that, and pricing seems OK as well (except for the de-lidded [email protected]$750...).

I am just surprised that 1.35/1.4v is considered as max on a 22nm CPU, while 1.4+ is still ok on a 14nm.

You cannot compare core voltages from Haswell to Skylake, there were large power delivery changes for each generation.

To be fair, a 4.9GHz 24/7 safe 6700K is almost unheard of, I'd be pricing one that high as well.
