"Overclock failed" not sure why

bios: 1101 (have read that newer bios have problems)

 

Windows 10 64bit

 

Originally I overclocked the cpu with a multiplier of 44, stock bclk, and a voltage of 1.30V. I also changed some other settings that the video I was watching recommended. I believe they were all pretty miscellaneous, the only one I remember was changing some value to 255.50 (approx).

Temps peak at mid/high 60C's, with ambients of 20-30C.

 

After using the computer overclocked for around a week it suddenly froze during Civilization V (had played a few sessions prior, all spanning a few hours) and on reboot I got the overclock failed message.

I then increased the voltage to 1.35V.

It has since been around four weeks since that happened.

 

Today, I was doing casual browsing then turned off the screen. 10 minutes later I came back and turned it back on, but the screen stayed black. After turning it off then on with the power button I got the overclocking failed message again.

I decreased the multiplier to 43 and am now typing this up.

 

Did I lose the silicon lottery or is something else being done wrong?

 

Thanks in advance.

Have you tried the Asus 5-way optimization tool that's included with the M/B software?

 

Most reports state it does well at resulting in stable OC's.

Eh, the only things I've read on it weren't favourable.

For now I'm loading optimised defaults and just changing multiplier to 43 and vcore to 1.33.

The problem with those - and the reason why it's able to make certain overclocks stable - is that they apply more voltage than what you really want, causing additional(and unnecessary)wear-and-tear on the CPU and heat.

too much voltage is just as bad as not enough in my experience. The answer isn't add more voltage, it's find the optimized values for your cock frequency. 

 

Random crashes is usually a result of not enough voltage or inconsistent voltage delivery. I'd turn turbo off and any other power saving capabilities - and then fine tune voltage control via benchmarks and stress tests.
