I´ve been searching around on this forum and read alot but i´m still confused, the thing is I have a Athlon XP 2600+ (333 MHz FSB) but it only runs at 2000+ and not 2600+, the bios I have is 1001.G, I checked this at asus homepage bios and the cpu support, for a 2600+ they refer to bios 1001.C but they ad that if the motherboard BIOS version number is greater than the BIOS version listed at the homepage, then one will not need to flash the BIOS. They reffer to 1001.C and I have 1001.G but I dont get the full capacity out of my processor...... my memory is running at 200mhz, ok all info is very welcome!
