Help Assess OC

[rodion.zissou]

I'm a newb. I need help dialing in my OC.

Specifically...

1. Once I dial in OC, how should I switch to adaptive, and what kind of offsets should I try.

2. In the screen below, under my MOBO specs in HWM, does it show I'm pushing 1.9v to my CPU? Is this dangerous?

3. What is the range of safe voltages for the 4790k? (Safe meaning not killing my CPU within 5 years of moderate-heavy use.

4. Should I trust the ROG RealBench result of "instability detected" over my passes in IETU and aida64?

Below you'll see some screens and logs, I'm hoping you can assess them better than myself. It seems I've hit a wall at 4.8ghzx4. When I try to go further, I have to push the voltage up to 1.325+ which I'm too afraid to try (should I be?) I ran aida64's stability test for 8hrs and got a pass(4.8x4 @ 1.275v). I ran it again for a couple hours this evening to take some screens. Any advice on moving forward would be greatly appreciated.

Dont go past 1.35v unless you are doing some serious OC'ing

Thank you very much, I've been reading, and it's hard to tell which voltages are actually safe. It seems a lot of people just want to push it to the limit disregarding a 24/7 kind of config. Could you spare any more advice?

I would see what i could get on ~1.275v for a daily thing but thats me

Cool, that's exactly where I am. But after a couple of passes with long test (aida64, and IETU) I got a fail in RealBench. I don't really know what that means for me.

What you see in HWmonitor is bug and I think its across all Asus Z97 boards. Your screen is second that I've seen with it. It isn't actual core voltage so you will need some more accurate software to monitor that.

Here are some tips.

 

Set LLC at Regular instead of Auto 

 

Use offset voltage increments of +0.010v. I would start with +0.050 for a 4.7GHz OC and if you successfully boot then stress test and if you BSOD then add +0.010 until stable.

 

Set CPU Current Capability at 130% - 140% This is in your Digi+Power

 

To get the best OC as a beginner, you should run the RAM at stock then OC the CPU when that is stable you can OC the RAM if desired, this way you will know exactly who is not stable.

 

I would trust the ROG Realbench. As Linus has stated and it is true, an OC is not stable until it functions properly on all installed programs. I can get a 4.7Ghz OC with 1.120v and all programs and games but one runs smoothly for hours on end but frigging COD Ghosts he need more Vcore. I have to use 1.243v to play that game smoothly and yes i know COD Ghosts was constructed by a 4 year old with no sense of common sense but still....

Great, thank you. I think I might bring it down to 4.7@1.275. Linus seemed content with pushing 1.3v through his 4790k, but I'm a beginner and it worries me.

I'll try your advice and report back.

Ok, that clears up A LOT of confusion. Thanks

I've found that the AIDA64 "CPU Core" and the AI Suite CPU Voltages are reasonably accurate under load on my Maximus VII Gene (verified with a DMM), so those are probably fine to go off of (they're within 0.010V in my experience).  The voltages vary more when you're not under load, but IMHO if the voltage is still lower than your maximum, what does it matter what they are?

 

In terms of setting an adaptive overclock, it's really easy.  Provided that you've got a multiplier/voltage pair from manual overclocking, you just put that manual vcore in the "Maximum overclock voltage" in the UEFI bios (or something similar, I don't remember the exact term) and set the offset to +0.001V.  I explained what adaptive overclocking does in this thread pretty well, as well as the difference between offset and OC voltage.  For the voltage, 1.3V is a generally accepted good value for Haswell and DC.  If you have thermal headroom, going a bit higher is probably just fine (especially when you dial in an adaptive overclock, as it won't spend 24/7 at that voltage).  

 

For stability, I validated my overclock with AIDA64, but ran into issues while gaming and actually using my computer.  To fix the instability, I bumped up my offset to +0.010V and I haven't had a problem since.  It seems that there's no clear cut way of validating a Haswell or DC overclock, so basically validate as well as you can, and see how it performs as you use the system.
