4790K overclock

[mteague]

Hi 

 

I was wondering if anyone could give me any advice on my system. I'm a noob with overclocking. I have overclocked my 4790k to 4.8, 1.264v with a +0.050 offset and when on manual voltage of 1.3v I used aida64 and ASUS PC Diagnostics to test the system. The test seemed fine had one restart which I didn't see the error too but I did another test for a hour and a half and everything was fine with temps at highest of 68-70.

 

However when I clicked stop on the test I got the error: 'Your PC ran into a problem and needs to restart'. The error if gave was memory management . I then ran Windows Memory Diagnostic, which seemed to work but when clicking the auto function in ai suite 3 (797 hero vii) I got the same your PC ran into a problem but the error was WHEA_UNCORRECTABLE_ERROR. I have used sfc/scannow and it didn't find any errors. 

 

Should I back off my overclock to 4.6/4.7 even though the tests were ok? It will be ashame if so as that was my target of 4.8 but if thats the only way to get the system ok then I'll go with it. 

 

Any help with this would be appreciated, and thanks for taking the time to read this.

I had this a fair bit on my last PC that was overclocked, and all the research I did pointed to an issue with Windows 8.1

 

Is that your OS by any chance?

I have the same CPU.

 

That's WHEA_UNCORRECTABLE_ERROR is what you get when the voltage isn't high enough to provide the cpu enough power. 1.26v for 4.8Ghz is very low and I wouldn't bet on it being stable. 1.3v is more realistic, although mine actually seemed stable at 4,8Ghz @ 1.312 after about an hour stress test. However, it wasn't it crashed expectantly. I would back off, or just increase the voltage a little, as long as your peak temperatures are low enough to keep you comfortable, then raise the voltage, but past 1.35V is where it gets risky and long-term usage at say 1.36V could significantly degrade the life-span.

His profile says Windows 7 Home

Hi yes that's my new OS, I've just updated my old profile. Ahhhh windows 8 is soon annoying.

Hi thanks for replying. Oh right, ok I don't mind increasing my voltage a bit as my highest temp reading when stress testing was 70 but it mainly hung around between 58 and 66. Have I set the adaptive voltage wrong then, I thought that setting the +0.050 offset would make the voltage equal 1.314, but I'm a noob at ocing so I coul be completely wrong?

Oh Just in case my motherboard is the Hero VII

Hey mteague, 

 

i´m running a 4790k @ a Asus z97-AR on save OC mode @ 1.220 volt @ 4,6 GHZ watercooled like 60-70 C

 

The Problem with the 4790k is the FPU 

@ 1,310 volt running @ 4.7 ghz @ 85- 95C with the intel Stress test.

 

So i run Stress test on Aida64 @ 5GHZ ONLY on CPU Stress like 65 C OO WOOT -  nice ????

 

But when you runnig the FPU the temps are to high on 4,5 GHZ -> shut down.

 

Most builds can pump to 4,5 - 4,7, no way more... or liquid ice but not @ home

 

Cheers DEV

Thanks for the reply Dev. I tested my FPU in AIDA64 and I hit 95c Is that not normal then to hit that temp on FPU? I've read a few forums and they said its normal so I'm unsure. I suppose I could test ai suites 5 way overclock to see if that gets a better overclock.
