Unless you have a goldfinger device, or special athlon overclocking (or underclocking) devices, you are stuck to lowering the FSB. I wouldn't mess around with it too much, you would throw off the entire computer WAY too much if you lowered it. If you could lower the muliplier manually, either via jumpers or dipswitches, you could set the multiplier as low as 100Mhz (100FSB times 1 for multiplier). That would be terribly slow however =/ I had mechwarrior a while ago, and it worked fine on my computer. I think you just need to switch the settins somehow =/ Oldie, but goodie
