XP2500M with A7N8X overclocking and BIOS query
I use an Asus A7N8X v2.0 MB, BIOS version 1007. Processor is an AMD
XP2500 Mobile CPU overclocked at 180FSB, 12.5x CPU (2250MHz). The system is stable at those BIOS settings, along with Aggressive memory timings and VCore at 1.65volts. I have a question about the BIOS Advanced Chipset Features, CPU Frequency Multiplier. The list of available multipliers starts at 13.0x, 13.5x, 14.0x then drops to 6.5x and climbs back up to 12.5x as the last possible choice on that BIOS screen. 12.5x is stable but if I try going up to 13.0x the system assumes the processor is only 800MHz??? Why? I also cannot get above 180FSB without instability. Anyone out there have other better achievements overclocking the XP2500mobile with the A7N8X?? Larry Gagnon |

Larry Gagnon Runnin same board/cpu with OCZ PC3200 DDR What ram are you running and is it rated for 200Mhz FSB? Mine @ 1.50vcore/11.5x200 for 2300 Mhz.....does 2400Mhz at 12x200/1.65vcore but I like the lower temps...never over 40c loaded with thermaltake volcano 9+ OZoNE |

You should hit a spot where it lists two Multipliers. The higher one is the one it will set it to. That is, if I remember it right, I don't have my "A7N8X" Board anymore.
