BIOS Settings Help -November System Builder

[joetheoverclocker]

Hello, I am following the "November System Builder $650 Gaming PC"
Using the same components as in the artical:
CPU Intel Pentium E5200 2.5 GHz,
Motherboard Gigabyte GA-EP45-DS3L,
RAM PNY XLR8 4GB (2 x 2 GB) DDR2-800 (PC2 6400) ,
Graphics Sapphire 100245L Radeon HD 4850 512 MB,

I am new to overclocking and having some problems.

I am able to adjust the clock ratio (downward, default of 12.5 is the highest it goes)in the BIOS or using EasyTune 6. But, when I try to adjust the bus speed with either EasyTune 6 or the BIOS it never seems to save it. Every time I check CPU-Z it says the bus is still at 200 MHz.
I have updated the BIOS and it still will not change the FSB.
I changed the multipler from the defualt 12.5 to 11 and the FSB from 200 to 333 and the vcore to 1.3 as in the system builder article. I also tried changing the multipler from 12.5 to 11.0 with the bus from 200 to 266.
Neither works!
After savinging the changes (f10) the system self reboots 3-4 times and loads the bios settings back to the original.

What else do I need to Change?

Is there more BIOS setting information for the "November System Builder $650 Gaming PC" on the site somewhere?

Any help would be greatly appreciated.
Thanks

You need to make sure you have the most up-to-date BIOS available for the board. You also need to manually set the RAM timings and voltage in the BIOS. Gigabyte boards require you to press CTRL+F1 when you first get into the BIOS to open up the advanced BIOS options including RAM timings.

If you want the FSB to stay constant at the speed you set it to, you also have to turn off speedstep in the BIOS. I actually leave it on even though my system is pretty highly overclocked. That way the chip runs at 2.4GHz when there isn't much load on it, but jumps to 3.2GHz when needed. I would suggest reading as many overclocking guides as you can before you start trying to change multipliers, FSB, etc...

The OC is unstable and the mobo is reverting back to stock speeds, after multiple tries to POST.

List your OC settings and I will see if anything is obvious.
