[Help] Overclocking 4790k

[Fraizer]

Hello all

I need please your help to make a good and stable overclokin withe my 3790K and my Asus Maximus VII Gene.

I am actualy stable on XTU stress test at 4.9Ghz vcore 1.275000v 78°c withe watercooling). i just use the multiplicator withe vcore and the memory en XMP mode withe 2400mhz and 1.6500v. I touch nothing else. (i can enter under windows at 5.0ghz but i have bug when i use XTU even i put vcore to 1.34v)

i realy dont uderstand all this options in the bios overclocking... i try to understand by reading different post but it like chinees for me :/

Somone nice ^^ can tell what i have to put exactly in the bios to optimize my bios ?

this is a video to show all the option in the bios (its not my Gene version but the Hero version withe an old bios but i think... it is the same)

That's actually a pretty good OC for a 4790k. Sounds like you're limited by the chip.

thank you kirbyrj

but i need to optimise all this setting to maybe have more and for sure more voltage stability maybe less voltage if i stay at 4.9ghz.

it will be great if somebody help me about this

 

[kirbyrj]

The only thing I would do is set your voltage to offset mode so it only receives all the extra voltage when it's under a load, and then reduce when it's not. Personally, I use the turbo OC so it jumps up to the highest multiplier when its under a load and the voltage adjusts using the offset provided. Then you can play around to see if it is still stable at 4.9Ghz or adjust it a little higher for 5Ghz.

If you can do 49x at <1.3V you have a nice CPU. Mine takes 1.35, and won't run r11.5 @ 50x no matter what volts.

You want to research delidding tho if you're hitting 78C with less than 1.3V, regardless of frequency. It sounds pretty scary, but it's really quite easy/painless. after delidding just clean the black sealant off the pcb and the ihs and clean the tim off the inside of the ihs, and put it back on with new, better tim. You can get some pretty great temp improvements without messing with lapping, or even liquid metal.
