overclocking on Gigabyte P67A-UD4-B3

post #1 of 6
Thread Starter 
hey guys,

I have a quick question.

The other day I was doing a just for lulz overclock to 4.5GHz at 1.3v (with vdroop it goes to 1.22v and sometimes 1.20v according to easy tune).

The reason i use easytune is because CPU-z and CoreTemp do not read my vcore accurately. For example in CPU-z it reads 1.052v or something, and in Coretemp it reads 1.35v

So I go by easy tune which I believe to be correct.

Anyways so I changed the multi to 45, and it didn't boot. It would just go in a boot loop with no display.

I found this rather odd that it didn't auto-correct itself and then re-boot or revert to the old bios settings.

My CMOS battery is located under my first GPU, so I had to remove the gpu and remove the CMOS battery for a few minutes to clear CMOS.

This was a huge pain in the butt, and I think it's horrible to have to reset CMOS every time there is a bad overclock -- ie not enough volts.

So my question is, GA-P67-UD4 owners, do you really have to reset CMOS every time there is a bad overclock?

Talk about inefficient overclocking...

There's a clear CMOS jumper at the bottom of the board. That's what I use.

I've only ever had to clear CMOS twice, every other time it would sort itself out and POST with default settings with a message stating the OC had failed.

Weird. The jumper and battery do not work. I can't even post right now.

I somehow managed to get it to work.

I think it has something to do with the bios.

This is a common issue if I'm not mistaken.

Which bios is best guys?

F3d is the one I'm still using, solves most of the boot loop issues. Few people went back from the newest f3 to f3d, I just left this one since it worked well for me http://forums.tweaktown.com/gigabyte/28441-gigabyte-latest-beta-bios-3.html#post270423

Use cpu-z ver. 1.57.1, it displays the right vcore, previous versions show the VTT voltage in the vcore box.
