For 8 months I ran my Athlon XP 1800+ (tbredb) on a SiS motherboard at stock speed because the bios didn't allow for overclocking. Then three weeks back I bought an nForce2 board because everyone has nothing but good things to say about it. I spent 70$ on the Shuttle AN35N-Ultra and 100$ on Kingston HyperX PC3200 512mb ram. I put my system together, and first thing I format and install winXP.
Everything goes well. Perfect. Time to overclock. Bump fsb up to 166, and run Prime95 and Sandra. Stable. Now since I dont want to push the cpu beyond 1950mhz, I bump the clock multiplier down to 9.5 and fsb to 200. No boot.
A lot of experimenting yields these results: I can't select any multiplier below 11. Everything above it works fine, 11, 11.5, 12, 12.5 ..... and on. But if I set the multiplier to 9,9.5, 10, and 10.5, the system ignores it and uses the default 11.5x of the chip.
So I do the wire trick, and connect the two pins on the cpu by using an ultra thin wire. Put the cpu back in, boot up. Same thing. Can't pick multiplier below 11.
What gives? I have the latest bios, a GF4, SBLive, and a Maxtor.
