OK - this is purely theoretical stuff - I've just downloaded the manual, follow this at your own risk!
Restart and get into the BIOS by pressing F2 almost immediately after the restart.
Go to CPU configuration and select the following;
Overclock Mode [CPU, PCIE, ASYNC]
CPU Frequency [333] - to begin
PCIE Frequency [100] - to begin
Boot Failure Guard [Enabled]
Spread Spectrum [Disabled]
Enhance Halt State [Disabled]
Intel (R) Vitualization Technology [Enabled]
CPU Thermal Throttling [Disabled]
No Execute Memory Protection [Disabled]
Intel (R) Speedstep (tm) Tech. [Disabled]
Go to Chipset configuration (hit ESC)
Memory remap feature [Disabled]
DRAM Frequency [333MHz]
and leave everything else as it is. You don't have a wide range of voltage adjustments, so I'm not going to try and play about with those.
What I have given you above is the starting point to overclock from. We have locked the PCIe bus independently of the CPU FSB speed and turned the RAM down so it should interfere with the CPU overclock (I'm assuming you have at least PC6400 RAM that will run at 400MHz, because that's where we're going next
Reboot the system (Save these settings and it should reboot fine).
Go back into the BIOS and select 350MHz for the CPU FSB setting.
Reboot. If it reboots fine then try 375MHz, if that reboots OK, try and get into Windows at that. If it loads Windows then try for 400MHz FSB. I don't think you'll get much more than that with the available voltage options but if you get that fan then you've got a handy 20% overclock on a really cheap motherboard.
Let us know how you get on and we can look at how to get beyond 3.6GHz if you can keep it stable at 3.6GHz!
