First time overclocking... i7 4790k

post #1 of 11
Thread Starter 
First of all, here are my specs: i7 4790k, H100 Cooler, Maximus VII Hero, EVGA 750w G2 Gold PSU


What would be the best overclock I can perform while still keeping it safe so my ***** doesn't explode? I've already explored a little bit inside my BIOS but all that I need now is the correct setup to overclock but I've never done it so I don't want to risk messing up... I know that I'm keeping this short but I wanna get straight to the point... It would be greatly appreciated. Any informations needed, I shall provide. Thank you smile.gif

Most can hit around 4.5 - 4.6ghz with good voltages

Thank you... Also, what's the difference between manually overclocking and using the EZ Mode or ASUS Optimal for Gaming mode from the BIOS? I'm running my CPU at 4589.16Mhz , 1.3275 Volts using EZ Mode right now and it seems perfectly fine...

EDIT: Now I'm running 4.6GHz at 1.225 Volts... Does that seem safe?

Stay under ~85°C and ~1,35V for 24/7 use and you're safe. Make sure it's stable too (test if it keeps running without errors under load/benchmarking).

Seems perfectly fine so far! What would you suggest for 4.7 or 4.8 OC? It's only a .2 upgrade from the original 4.4 that it's automatically boosted up to... I'm 100% certain my rig can push 4.8 safely with the right voltages... I'm just not quite sure of it

Often the voltage is not the problem, the temperature under load is wink.gif. So just try to up the voltage with the frequency and see what you can get until you hit ~85°C under load.

Most of the time past 4.6 the voltage and thermal requirements rise exponentially. Unless you live in a freezer I wouldnt expect anything past 4.6 GHz.

4.7 may be possible if you have a beyond exceptional chip, but it is very unlikely.

Many chips hit 4.7ghz on reasonable voltages.

Difference between manual and automatic OC is mainly down to safety and optimization.
