I am a newby to overclocking and need some help overclocking my rig, Gigabyte motherboard (G31M-ES2C), Intel core 2 duo, 2.8gig, and 1gig NVIDIA 9800gt. Can some one point me toward some safe BIOS settings? I have Everest installed monitoring all temps just need the other stuff to start burning this baby up.

Is that 2.8GB of memory? If it is, what processor do you have?

If you've got an E7400 (ie, 2.8GHz) and a G31 chipset, then that's 10.5 x 266. Anyway, you can go up to 333 with G31s. Some G31's will fall over a few MHz over this, maybe 340, others go further. If you've already go a 1333FSB processor then there isn't much room to move, but if it's 800 or 1066 then good.

In BIOS, go into MIT, enable the host clock and go to 300 or 333 and see how you go with standard voltages. Keep your memory frequency as low as possible to start with (ratio 1:1 or so). It should be ok.

Yes, there is plenty of reading out there on this. Everyone has a different idea.

Not true. The basic principles do not change.

Increase FSB until system not stable. Increase voltage a little. Test.
Repeat until:
1. You reach your goal.
2. You reach the CPU's voltage limit.
3. You reach the CPU's thermal limits.

Keep in mind that the following are guides, not cookbooks.

This is for a GA-EP35-DS3L motherboard, but the Gigabyte BIOS's are all pretty similar.

You will need better cooling than the stock heatsink provides.

Everest is not the most reliable program for checking CPU temps. CoreTemp is better.

Go into the BIOS" tab and set the motherboard thermal alarm to 70 C. And enable the CPU fan alarm.
