Achieving higher overclocks? +questions about i7 4790k

[SiGaG]

Hello friends! Recently I've been competing with some friends overclocking the i7 4790k.

My weapon of choice has been the MSI z97 Gaming 5 motherboard and a corsair CX750m

My cooler is a Corsair H100i running push/pull outside of my case.

Currently I've been able to stay stable at 5.67Ghz 1.3v and my hottest core at 63C under 100% load.

I've already disabled hyper-threading and have been considering disabling cores.

Is there anything else I can do to get higher clocks?

Also I understand 1.3v is supposed to be the max safe voltage. Can I run my cpu over 1.3v if the temps stay low? I've seen a lot of mixed answers regarding the max safe temps for this cpu  but the general conclusion is that it shouldn't pass 72C? Can anyone confirm this?

Is that a joke?

You're so lucky. You hit the jackpot with that CPU.

Jackpot?

Jackpot?

Yeah, you got a good CPU in the silicon lottery. Thus the jackpot. With just an H100 you got 5GHz+. That's insane.

: D I never thought there was a big difference in off the shelf cpu's. I mean i know there are slight variations but I figured it was very minuscule. I'm still trying to figure out about the max voltage though and what I can do to get higher clocks (without having to use ice/LiqNitro)

[Faceman]

85C and lower for 24/7 use is considered safe.  1.3v and lower is also considered safe.  Of course you can push it higher, but that is when you enter the more risky temperatures and voltages.

Any chance on getting a CPU-Z validation on that? ---> http://www.cpuid.com/downloads/cpu-z/1.71.1-setup-en.exe

I trust Win 8.1 task manager about as much as a clepto. Sorry to be a downer here, but there's no way that thing is running 5.67 @ 1.3v.

[HumdrumPenguin]

I'm running mine at 4.8 @ 1.3V using a H100i and that's a quite good cpu as by what i've seen so far. How the hell did you get to that frequency at the same voltage? Makes no sense at all.

[SiGaG]

Sure I'll be able to post it sometime tomorrow. I just powered her off for the night.

because it's not. Common problem with Win 8.1 and task manager

To get anything remotely close to that clock you would need to be running North of 1.65v and on LN2 or Phase http://lab501.net/intel-core-i7-4790k-intel-pentium-g3258-overclocking-study/25/

[TOMPPIX]

BULLSHIT

[SiGaG]

Very disappointing Cupz says it's only at 5.1 wtf makes task manager say that?????

[johngo90]

Yeah I have a very hard time believing that these clocks are true especially just on an h100... Please post screenshots and validate your claims. Even 5.1 seems ridiculous at 1.3v only hitting 63 degrees.

will do. I think something may have failed though. I'm just getting 5 beeps when i turn her on. Good thing I got insurance.

[johngo90]

right...

Reset CMOS and that should get you back into the BIOS. If you were actually at 1.3v it's a miracle it made it to the desktop at 5.1. If you didn't manually set the voltage and left it on auto or adaptive, or used OC tuning software, you may have been drawing well over 1.3v and could have caused some damage.

Post a cpu screen shot and a cinebench score so we can take you and this claimed stable oc seriously

I will as soon as I determine that I can safely run this clock again. Give me a few min .

I was using software to OC not the Bios. Pulling the Cmos battery let me boot. I booted in safe mood and disabled the program.

Oh sweet jesus. DO NOT USE OC SOFTWARE! Especially when plugging in that multiplier. The way a majority of OC software works is that you set a multiplier, it will apply as much voltage as it deems necessary to hit that clock. AND it will vary that voltage delivery, much like adaptive. Sooooo if you go trying to start a bench in XTU, Prime95, whatever; it may in fact say 1.3v when you're looking at the desktop, but as soon as you start a bench it could throw 1.5v+ at it.

 

What you are doing is dangerous for your CPU and board.

 

If you want to OC take the time to learn how to do it manually. This is a good place to start: http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics

Temps better than custom loop on xeon. Guess that tells you something about TIM of haswell...

You are the luckiest person to get that overclock, like seriously.
