I'm currently looking at the manual for the p31 s3g board I have here (in the bios section). I will assume that the es3g is the same or similar.
In the MB Intelligent Tweaker (M.I.T.) section, you need to change the "disabled" to enabled on the line that says CPU Host Clock Control. You can then change the number (that should be currently 200) to the right of the line that says "CPU Host Frequency (Mhz)"
For example, if you type in 250 next to that line that says CPU Host Clock Control, then it will raise the speed of your cpu and make it 2GHz.
(There should be a line right above that says CPU Clock Ratio or something similar. Yours should have an 8 there.)
When you type in 250, then it will automatically overclock your RAM at the same time.
There should be a line in the bios that says "Memory Frequency (Mhz)" with an 800 beside it. To the right of that number should be another number which will probably say 1000 (or something other than 800).
Now above that line should be another that says "System Memory Multiplier (SPD)". It is probably on auto, but you can change that to something else. Go to that line and look at the different options other than auto. If you change it to something else, then notice that the number beside "Memory Frequency (Mhz) 800" will also change. If you pick 3 for example, it will multiply the 250 that you typed in the CPU Host Frequency (Mhz) line by 3 to get your new memory speed of 750MHz.
There should also be an option for 2, 2.4, 2.5, and maybe a couple of others. You can try the different ones to see what your new RAM speed is.
I try to keep my RAM at or below its rated 800MHz.
There is also a line that says "Performance Enhance" with "turbo" to the right of it. I've read that it is best to change from "turbo" to "standard" when overclocking.
If you type in 300 in the line that says CPU Host Frequency (Mhz), then your cpu will be 2.4GHz. You may have to raise the CPU Voltage control though.
I am not very good at explaining things, but there is an overclocking guide here if you want to check it out and it will explain things better than I did.Edited by TonyLee - 12/22/08 at 6:14pm
