I upgraded a OC system using an K7S5A to a Asus P5P800SE with a D 805. I had an extra case laying around and decided to put the K7S5A back to a working state. I did some quick research the othernight and have noticed that there are now 3rd party OC flashes for Ocing. I believe the board is a V.1. The bios date in the Bios is 1/12/2002 S. The number at the bottom of the boot screen is: 62-0112-001011110940201-SiS735-K7S5A. The bios numbers when in the Bios are AMI BIOS Simple Setup Utility Version 1.21.06. It's been years since I oced this board so I don't remember what version I flashed it to. I assume the current version of the bios is located in these numbers. 62-0112-001011110940201-SiS735-K7S5A I want to save the current bios before flashing it to a newer version in case the newer bios don't work as expected. Do I need to use the flash utility that was used before which I assume is the 1.21.06 version to save the current Bios and restore it if needed? Or can I use the newer version which is aminf342? I want to add more FSB / MEM selections to OC the chip a bit more. Currently it is only showing 100/100, 100/133, 133/100, 133/133. I have seen there are bios's out that have fsb selection in between what I currently have.

I would appreciate your comments and help on what version bios it is running and which is the best OC Bios to go to and the AMI issue. DataCom
