The GIGABYTE Z97X Overclocking Guide - Page 25

post #241 of 286
Hey Guys

First of all Sin, thanks for this amazing guide.
It helped me alot on getting my i7 4790K to 5Ghz smile.gif

Im running my 4790K at 5Ghz with 1.452v, voltage spikes up to 1.464 under full load.
idle temps I think are great, between 29 and 32C on all cores and when doing a cinebench run max temp is around 80-84C.

I dont dare to run intel burn test or Prime95 at this voltage because that will probably kill my CPU lol, but ive been stable for a few months now so im happy.

I just had one, or actually 2 question and those are: if anyone knows what the max temperature of the mobo is?
HWiNFO64 is showing my system temperature was 45C after playing Call of Duty Black Ops 3 for about an hour, and I wanna know if this is too hot?




Second question.... is my VCCIOA voltage of 1.254 safe?



Would be great if anyone can answere these two questions for me, because I might need to lower my RAM overclock. Im using 1.8v on the ram voltage and 1.254 on VCCIOA just to be able to run better timings on my G Skill Trident X 2400 CL10 DDR3 RAM, so its not really overclocked actually. Just the timings are tweaked. But im wondering if it is worth it?


Thanks smile.gif

U r quack!

1.45vcore check. 1.8vddr check. For 24/7 that is definitely quack. Sins guide has some values for air and h2o ovetclocking and your values are extreme. I wouldnt use your settings unless chilled 24/7.

This is a useless comment to me. I know my vcore is high but I never let my tenps go past 80C for a long period of time so I dont really see why it would be a problem using these settings for daily use like gaming for a few hours.I only wanted to know if my system agent voltage is too high and what temperature is normal for my mobo and you answered neither of those things so not very helpfull. I know my voltages are a little extreme but aslong as temps are okay Im not really worried. So yeah.. Thankz anyway I guess.

This is what I had to use on my Z97X-UD5H after flashing the newer BIOS...after that you can't use Qflash or @BIOS and must use FPT.

Omg dudeee it worksssss. I had the same problem and even contacted gigabyte and even they couldnt fix it for me but now I am back at F6 which is much much better than F7 or F8.
I cant thank you enough man, you have now idea how badly I wanted the F6 Bios back and now I have smile.gifwheee.gifthumb.gif
Now lets see if I can get my original 5GHz overclock back with under 1.4v sonic.gif

cheers.gif mate biggrin.gif

Not really sure how you can not let your temps go past 80C at that voltage, unless you somehow are able to set the temp throttle in BIOS to 80C. Anything can really kick in the AVX instructions (media usage/editing, gaming physx, and maybe not today but in the near future) without you being really prepared for it, then temps will sky rocket and even throttle. You do have the best AIR cooler though, so that should help in those cases to keep temps from climbing too fast.

On your VCCSA voltage, have you tried backing down on it? Or even try AUTO? I know that many overclockers and reviews suggest maxing it to 1.25v to avoid IMC troubles with 4xDIMMs or 2400MHz+ memory, but that's not really necessary. I suggest testing the limits of your CPUs IMC before letting the max volts run through it for continuous use.

For perspective, my 4790K is able to run 4x8GB at 2666MHz with it set to AUTO, which I measured at 0.86v with a multimeter. That's only 0.01v bump from the default of 0.85v for my motherboard. For faster speeds than 2666, I have had to bump it manually, but still only by like 0.2v to around 1.0v. Worth a try, if you haven't.

Okay well now u are helping me thumb.gif

I stopped using stresstests like AIDA or prime when I hit 4.9/ 5ghz because there it would get me towards 90-95C.
Instead I continued by just running a Cinebench and see how that went and from there on if I got a BSOD in the very beginning of the run I upped vcore by a slightly greater amount than what I would raise it with if Cinebench failed at the end. After passing Cinebench I just went gaming for a couple of hours and at the beginning ocasionally I would get bsod, but at this point I think I am stable enough for my own type of usage and haven't had a bsod in a few months now. I do always monitor temps when gaming or benchmarknig, I might not be 100% stable or ''prime stable'' and maybe ill get another bsod tomorrow, but this has been my (safer) way of getting to my 5GHz overclock that is working very well for me now.

And now I got my F6 Bios back thanks to Mandrix, which worked much better with my chip ill have to do some re-testing and ill note your tips about the IMC voltage too so I can see how it works out.


Thanks alot for taking the time to hand me those tips. Ill post back when ill have done some more testing thumb.gif

So is there any point in upgrading to the F7 or F8 bios? I can't seem to find any more info regarding them besides what's listed on the Gigabyte website. Currently running F6 bios with a 4790K stable at 4.7GHz

Definetly keep F6. F7 and 8 are more optimized for Intel 5th generation processors as stated on the gigabyte website.
With F7 and 8 you could end up like me having to add more vcore because your oc is not stable anymore. So yeah definetly keep F6 !

Good to know! Thanks and +rep
That's +1 to procrastination right there. Lol
