Overclocking 4790K in Intel XTU

[wiebevb]

Hi there,

 

I am trying to run some higher clock speeds on my 4790K in the Intel xtu utility. My 'start clock' was 4.4 GHz, and I tried to overclock all cores to 4.7 GHz (47x multiplier).

When I run a stress test for a couple of minutes, my temps only increase a little bit (like 4 degress celcius max). On 4.4 Ghz the highest core was at 56 degress, on 4.7 Ghz +/- 59 degress max.
I am running on 1.2 V on static. I would espect that this kind of voltage will give me a BSOD fast.

 

It this voltage possible for the CPU, and does it have so little effect on the CPU temps? Maybe XTU is not affecting the clock speed at all, but I did see around 4700 MHz in RealTemp.

Does someone have a clue?

 

Cooler: Noctua NH-D14

Ambient temp: around 18 degress celcius now (usually around 20/21)

Stick to manual BIOS overclocking. Software OC'ing is bad.

what did you use to stress test and how long did you test it?

I used the intel XTU utiltity itself, it has a build in stress test.

Yeah, i think i am gonna do that right now, the only reason i did it with the software is to test the OC.

yeah bios oc'ing is much better and i'd recommend using prime95 for short term stability tests and aida 64 for long tests. good luck

 

also yeah those voltages seem low for 4.7 but time will tell if it is stable for hours in aida 64

I used prime95 before, opened another topic for it. Gives me much higher temps, than other stress tests like AIDA64. Some guy there telled me that prime95 was not optimised well for Haswell based CPU's.

 

Another question, is it the best idea to put the CPU voltage in static mode?

until you are sure it is stable yes. then after that you can enable turbo and use adaptive voltage using the voltage you set in static mode as the upper limit, this way your cpu will draw less voltage when not doing heavy work. but don't enable adaptive voltage until you are sure it is stable.
