4790k Overclocking Help

[km00000]

I watched Linus's guide for overclocking the 4790k. 

 

I have an Asus Pro Gamerr Z97 Motherboard. I configured for a manual 1.250V overclock to 4.4Ghz. After I clicked save and exit, it seems to be stuck at the screen where it prompts me to "press DEL or F2 to enter UEFI BIOS settings".

 

After waiting about 5 minutes, I held down the power button (mistake?) and pressed it again. The computer booted just fine and I ran Cinebench. CPU-Z shows a 4.4Ghz overclock. Cinebench shows my 4790k to be at 4.0Ghz. Which one is correct? CoreTemp also shows 4.4Ghz.

cpuz is correct

 

holding down the power button to do a hard reset is fine. its what you have to do sometimes

I am now running IntelBurnTest to test stability. It's bringing my 4.6Ghz 1.277V to 95 degrees. Is there somewhere I can check to see what is reasonable and what isn't. I am afraid I might accidentally overclock too high trying to find the limit. 

 

IBT finished with a success with 20 runs in 250.47 seconds

Is that the lowest you could get the voltage? Mine runs on 4.4 at 1.22... Otherwise to get to 4.6 I need 1.26 which I need to improve my cooling situation first (I need to re-do my thermal paste, I'm fairly sure) and it seems you might also be able to get lower heat if you can drop the voltage and have it stable. Otherwise that's fine, somethings things bork on boot and just resetting is fine and nothing to worry about!

 

Edit: Checking your new post, have you got it set to adaptive still? Try and make sure it's set to override otherwise it will increase the voltage on you.

When I overclocked my 4790k, I first found the lowest voltage that my cpu would run stable at 4GHz then I just increased voltage and clocks from there.. I got to 4.6 at 1.18V and I couldn't go higher because I have a Z87 Mobo..

I am on manual set to 1.275V. I have a 212 EVO CPU cooler. I'm fine with a smaller overclock now until I save up more to buy a liquid cooler. Don't know exactly how much it'll be better in terms of cooling, if at all. I'll research that later.

 

Going to decrease the voltage to 1.265 and run IBT and Cinebench again.

I have a 212 EVO cooler. I'll try to go down to 1.18V but I'm afraid it'll start going above 100 degrees.

 

Edit: That doesn't make sense.... I am majoring in electrical engineering and I am disappointed in myself for posting such statement. Lower voltage will might make it unstable not make it hotter.

Mine won't do 1.18 stable at 4.4 but every chip is dif, I'd say go 1.22 and see if that's stable and lower from there!

check the youtube link in my sig. might be helpful

It worked at 1.260V. I'll lower it to 1.22 and see if that works. Do you keep your CPU fan at max speed all the time? I bought an R5 to keep my room quiet and I maxed the CPU fan for overclocking. Should I go back to a standard increase RPMs as temp increases or leave it running at max speed all the time. It's feel like unnecessary power consumption

So long as it's in the CPU fan header it will auto-adapt. Running a fan at 100% the whole time isn't good for it, let the mobo handle it

honestly you won't see amazing performance gains going from 4.4 to 4.6 or 4.7. It's not worth the hassle OC'ing in terms of stability testing and possibly heat output too. Remember the 4790k is a factory OC'd version of last years 4770k.

I like to load a lot of random applications when I boot because I should have the CPU and RAM to do so. And just going from 4.0 to 4.4 to 4.6 I could tell things loading a couple seconds faster. I am going to be doing a lot of simulation this semester for labs which will make use of the higher clock speed.

 

I did blue screen at 4.6Ghz and 1.22V. Going to try 1.24V.
