Intel 4790K OC Report ~

Intel 4790K ES C0

Cascade and LN2 limit testing




4Core / 8 Thread

5Ghz ambient F1 with fan 1.25vcore

5.5Ghz -20c 1.5vcore 1.8v input

5.9Ghz -100c 1.6vcore 2.2v input runs everything

6.0Ghz -130c 1.8vcore 2.3v input Runs 3D threaded, no heavy CPU tests

6.1ghz -135c 1.85vcore 2.4v input

6.2ghz -140c 1.9vcore 2.5v input Runs 2D single thread

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.
