Hi, I recently bought a NF7 motherboard. I already have an athlon xp 2400+ cpu and want to oc it. The multipler was locked and the NF7 board could not unlock it. I decided to try Gao's method when you connect 2 pinns on the cpu but it did not work, the multipler is still locked, I've used conductive silver paint and twisted wire but nothing works.
Is this a common thing and is there any other method i should try?

I also have another question. Now I am using the intergreated sound that is built into the motherboard (no soundstorm). How muck performace do I drop in games compared to a "real" soundcard?
