Anyone overclocking a Gigabyte 965p DS3p in bios?

[Jon]

Hi, has anyone actually managed to overclock this board using the bios? Setting host clock to manual returns to auto everytime I reboot. Even if I select manual and choose all stock settings, it still reboots at auto. At the moment I am having to use EasyTune 5 to overclock it!

I also noticed that changing the pci-e lock to 100 also returns to auto on reboot. I've already flashed the latest bios and it makes no difference.

Did u reset cmos after bios flash

I reset everything, loaded defaults and made all my changes again and saved them.

According to gigabyte "tech support" it is a safety feature designed to protect from overclocking gone wrong.

But all I did was change host clock freq from disabled to enabled... then set it to 266 (which it should be anyway). I hadn't even started overclocking.

Edited: As a few people are having this problem, I thought I'd just update with what solved the problem for me.

There appears to be a bios bug which prevents you from even enabling overclocking when you have usb devices attached. I managed to get away with a usb keyboard and mouse. But any other usb devices cause it to reboot even at stock speeds. I am now using a PCI usb card at it works fine.

Also worth noting is it runs the memory at 1.85v regardless of brand. As mine requires 1.9-2.1v I had to up this to get it running stable, but this was not the cause of the rebooting for me.
