5.9Ghz -100c 1.6vcore 2.2v input
6.0Ghz -130c 1.8vcore 2.3v input
6.1ghz -135c 1.85vcore 2.4v input
6.2ghz -140c 1.9vcore 2.5v input
6.3ghz -142c 1.91vcore 2.5v input (instant crash)
1.95vcore = instant crash @ -140c
2.6v input = instant crash
I need to test the memory controller more
Memory controller maxed out a little over 1.4v -130c 5.5Ghz, 1.4v @ 5.2Ghz seems to be a close max stable
Cold bug factory defaults in bios at -120c
Cold bug 5.5Ghz boot -140c
Cold bug 6Ghz 4c8t idle -141c ~ loaded -150c
You gotta get chip warmer to get it colder
It clocks better and goes colder with 4c8t, removal of HT and cores makes cold bug worse.
This chip is binned for review sample, it should be close to what you get from retail.
With the new chip you get more Mhz on air and water but you can see the wall trying to reach the last few multilples on the top end.
This chip is better than any retail 4770K that I have tested in the past year.
Two of the major changes help with getting all retail chips to 5ghz on air, The TIM and the added resistor packs on the back of the CPU allow more voltage and that pushes the chip a little harder to push past 6Ghz.
Out of interest, what can it do @ 1.3v max? I ask because I am considering using one for a little gaming machine for my nephews (Lego games etc) and don't really want to go over 1.3v for them.Quote:

Seems very similar as my 4770K...I got 6.01 GHz, but I was limited in BIOS with input voltage :-/. Scaling seems similar (CPU voltage/VRIN/ frequency)Quote:

Disappointing overclocking results.Quote:

According to intel website, i5-4690K and i7-4790K support VT-d
http://ark.intel.com/products/80811/...up-to-3_90-GHz
http://ark.intel.com/products/80807/...up-to-4_40-GHz
Wow, did not expect that, intel actually did a decent thing by NOT DISABLING it, before it was just a douche move because "well F U dear customer"Quote:

Finally new CPU do 5GHz easily like my i5/i7-2X00K series.
Seems everybody for Reviews use same CPU batch.......L336D081...QG81 ES.
Only Hexus use different....L410C691...QG81 ES.
Still waiting for Retail results.
I just started reading this paper on dim and dark silicon that may shed some light, no pun intended. It's at least very interesting.Quote:

Nice! Looks interesting, thanks for sharing!Quote:

Most chips seem to max out at 4.8 ghz or so. Now if the retail samples are better ill have to replace the 4670k..Quote:
