Hi guys sorry to go a bit back to basics but i have been away for some time from the OC scene.

I have a pc i built 2 years ago which has reverted back to its factory defaults due to a dead battery.

I would like to OC again but having tried a few small tweaks the pc keeps shutting straight down.

could anyone suggest a good starting point which will produce a stable overclock and i can work from there.

my hardware is as folows:

GIGABYTE GA 965P-DS3P IP965 S775

INTEL CORE 2 DUO E6420 2 X 2.13M

CORSAIR XMS6400 2GB (2X1GB) 800MHZ

4 x CAVIAR 250GB 16MB 7200 SATAII

BFG 8800GTS OC 640MB PCI-E

CORSAIR HX520 520WATT PSU

Also i am looking at all the voltages and bus speeds etc on the Gigabyte bios and its not as straightforward as i remember, could someone point out which are the important ones.

I have CPU-Z, core temp, Fan speed and Orthios ready to help

Sorry again for the real Noob questions


Many thanks

Edit: Pneumonic beat me to it with a link to a much better resource....

Never used giga boards myself, but most mobo's are alike these days.

Ok main things to look at are:

FSB Speed/ratio
Cpu ratio (multiplyer)
Vcore (core voltage, or whatever its called on ur mobo).
Northbride voltage (sometimes known as MCH)

Memory to FSB ratio
Memory voltage
Memory timings

Ok so your cpu has a multi of 8, so keep that as it is for now. It will currently be using a fsb of 266, with stock vcore.

So from here its best to raise the fsb up by say 5 at a time, save and exit bios, seeing if it will boot up into windows. Keep doing this untill it refuses to boot, then at that point you will know that you will need to raise the vcore. Its a long winded way but the best way im afraid.

Memory i would let the mobo do it, so set all memory related stuff to auto, especially memory to fsb ratio.

You are safe upto 1.5vcore on that cpu, but ofcourse temp permitting. Your motherboard officially supports 333 fsb, so anything over that you may have to raise the northbride/mch volts a notch or to.

Hope this helps, and hopefully people with more experience of gigabyte mobos may post.
