Odd behavior 2600k & Z77X-UD3H

post #1 of 3
Thread Starter 
I was stuck at 4.2GHz, that's what I use every day. I wanted to overclock to 5GHz as I wanted to show my friend how easy it was to overclock.

I go into the BIOS make the changes and boot into windows... still at 4.2GHz and same voltage.

I reboot make again the changes and I make sure I really saved the settings. Again I still failed to modify the frequency.

Today, I reset the CMOS and I manage to overclock the computer to 5GHz, boot into windows fine.
Aight it works now, I reboot to go back at 4.2GHz. I change the settings and boot.... still at 5GHz!

I can't change the frequency unless I clear the CMOS every time.... ?
I have the latest BIOS version F19e.

I don't know what is going on. How could I solve this?

when you went from your 4.2 daily overclock even though you booted into 5.0ghz it wasn't stable and if it didn't crash it was about to. Anyway so when you restarted you voltage was set where you run it at 4.2ghz which is no way enough for 5ghz which it was still at. So reset cmos everytime or over compensate for voltage when going for I higher overclock and back it down slowly.

It didn't do that the first time I used it.
I was fine at 5GHz but couldn't go back at 4.2GHz.... I was stuck until I did a cmos reset.
I tried 4.2 to 4 or just changing the voltage and it's not working.
