My 1.3 Athlon was only running at 950. I have altered the jumper switches on the motherboard but have only increased it to 1.1. I can't see anything in the BIOS that can increase the speed any further. The motherboard is a Gigabyte GA-7IXE4 but there doesn't seem to be anything to do with Advanced Chipset Features on the BIOS list.
What cpu do you have the 266fsb or 200fsb. You say you have altered the switches on the motherboard do you mean the MHz ie to 115. Your motherboard will take 1.4MHz 200fsb Athlon with latest bios. Going on what you say I think you have either 1]Not have latest bios 2]Your cpu is 266fsb
I think I have altered the jumper to it's maximum of 115 which gives 1100mhz on the processor. I will try your advice Bremner and see if I have those settings. I have already had a look for the BIOS update and can't seem to find any joy there. Thanks to both of you for your suggestions.
