Hi and welcome to the Gigabyte Forum.
Please can you list your hardware including PSU make/model so we have a better idea of your setup ?
Also what OS are you using ?
PSU: Powerup Model LC-B350ATX
Motherboard: Gigabyte 8PE800 Rev 1.1 BIOS F9
CPU: 3.0Ghz Northwood
RAM: Promos Technologies 1GB V826765K24SAIW-D3
Graphics Card: Nvidia TNT2 32MB
Optical Drives: GCR-8523B & GCC-4480B
HDD: Maxtor 6Y080L0
O/S: Windows XP 32-bit SP3
My question is what do I need to do in order to have the CPU run at the full 3Ghz ? If I need to modify the BIOS settings, what settings are needed.
