Fugger, how hot is this chip in Superpi with 1.5V?:)
I didn't have monitoring up, I would imagine close to 80c
I was stressing it a bit with 1.5v, could be done at 1.4v but I was clocking up to 5.4G on air with that at boot.
Updated again, added more defined vcore to temp steppings.

EDIT:
Big welcome to dhenzjhen, about time!
Thanks BeepBeep2, bout time to join and learn from the elite folks here :)
Did some 3d runs with my chip also

Interesting thread, thanks for all the information provided, Charles! :)
Thanks Oliver,
Welcome to XS and yes, very nice cpu. mine is unstable at 6.3Ghz
4790K ready to play :). First results at weekend with AIR (today Im working with baytrail vs Kabini review and at benchtable with i3-4330)

Nice , very helpful information. Charles if by chance you have a single stage phase unit around -35c load , can you please do a quick test for me and check max Mhz stable on any 3D benchmark ? 2 cores / 4 cores no HT, Thank you. OR Maybe someone who has tried can report this as well , maybe Allen , DJ or Michael who also play with SS and have a chip. Almost forgot , welcome to XS DJ :up: about time bro.

hey Charles, This was a great read. I haven't been paying much attention to the new chips so its nice to see this. Lot's of useful information in there.
I appreciate all the time you put into this. take care
Thanks everyone, I have moved the 4790K over to water cooling for the next few weeks.
I was able to run the 5Ghz XTU, my cores reached 100c and there was a lot of throttle going on with 4c8t.
Thanks guys ^^
Looks like I may have found another candidate to go cold. 05 looks lil better compare to the first one
that did 1.395v.

Fantastic results there, 5G at 1.4 ish is pretty schweet for that chip. Thanks again
DJ, you need to run AIDA 64 more, you are out of control fast and should watch read/write/copy numbers for best results.
Your sub timings are off, tWR I think needs to be a 5 @ 2666, 2800 if you are watching AIDA 64 hurts performance on write and copy by >10%
Thanks ^^ but not really doing 5ghz spi32m runs, just boot and go on both 05 and 32m just to test the chip on air.
you have really GEM like allways :) My is rock stable at 1.3V only for 4,6 GHz for 4,75 GHz i need 1,4V, 5 GHz is not reachable at 1,7V ... :(
With High end Noctua air cooler
Quick tested yet, but stable seems up to 4700 MHz with 1.375 V. Hard benchmarks ending at 4800 MHz with higher voltages (1.44V). Gelid cooler+4000 RPM Delta fan :-)

cooling air cooler Gelid Tranquillo+Delta 4000 rpm. I cant get more (maybe +0.1MHz BCLK) :-/. I hoped for 4800 MHz, but it crashed again and again. I tried steps from 1.35V-1.45V for Vcore and combination of vccin from 1.75 to 1.97V, tried PLX and still nothing. Seems average 4790K at air. Charles has better, I believe :)
PC Per managed 4500mhz at 1.2volts and that's it. Most people (maybe not around here but in general) including myself aren't comfortable going above ~1.2V for 24/7 usage. Normal voltage for the 22nm process is what, ~1.05V? Temps might be lower but it doesn't reflect in better overclocking. Mr Fugger has a golden sample in his hand, is my guess...
looks like...There is my chip: http://www.xtremesystems.org/forums/...-Devils-Canyon
