i7 4770k to 4.5Ghz - Crash after 10-20min and then stable for the rest of the day

[VeinBe]

So i use a i7-4770k which i have overclocked to:

• 4.5 Ghz and 3900 ring ratio
• Cores at 1.25V
• Ram 1600mhz with 1.63V

The cooler is a nhd-15 with 2 fan setup.

The scenario is that it crashes after 10-20 minutes and then after that it is totally fine for gaming the rest of the day (10-12 hours). Is that being unstable? Is this a sign of something?

 

And no, i put the overclock settings back on after the crash so that ain't the reason for why its stable after 1 crash.

try undervolt ram voltage.

 

maybe your mobo not strong more.

Aight, will try. Undervolt, does that mean below 1.5V?

It's definitely unstable, but maybe just barely.

I had to do 1.35V to get 4.5GHz stable on my i7 4770k or 1.4V for 4.6GHz.

 

You can also try to increase the VIN voltage from the default 1.8V to 1.9V and adjust the LLC (Load Line Calibration) to a higher level before you go and increase the core voltage. If that won't help, then you maybe need to up the VCore to something like 1.28V to 1.3V if your cooler can keep up.

don't know

as far i know, the problem about overclocking is switch up/down voltage. switch up when you want tweaks, switch down when always crash.

So i've kept running my 4.5ghz on 1.29V overclock. But whatever i seem to do. it crashes at 10minutes mark. 10minutes exactly each time. and after that 1 crash it can run forever.

what sort of crash? bsod? power off? any error code?

Your previous overclock has failed. Thats about it. MSI motherboard. And the only thing i do is to save the same overclock setting and then it works for the entire day lol.
