please please help[

The 945 is really not an overclocking chip set. Its main use is for stock speed systems with integrated video. I have not seen the ASUS board, but Gigabyte and others do not support overclocking with this chip.

The E4400 with at least a P31 chipset would be your best bet. A P35 chipset would be even better.

In either case, I doubt you will be able to go beyond the 266 FSB of your ram. If the BIOS allows, set the CPU FSB to 266 and see what happens. If the machine does not boot, simply reset the CMOS and all should be back to normal.

Bios is limited by the mobo and written for a series of mobos. You can't put a monster bios designed for a OC tweakers mobo into a low end mobo. You got a very basic mobo. Replace it or live with it.

If your gonna replace the mobo, you'll need different ram since your running two different brands if you want to OC well.. And you have a aftermarket CPU heatsink? And thought about new NB and SB heatsinks? You will generate a lotta heat, many standard heatsinks can't keep the temp down. And does your case have enough cooling? What about your PSU? Is the PSU a tier 2? What about video? What card you running?
