I just installed my new mobo and processor. I currently only have PC100 memory, but my processor is a 1.33ghz 266fsb Athlon. The asus A7V133 won't let me specify a 133 external clock frequency with pc100 memory... So I left my clock frequency at 100mhz. Is this a problem, or will this be okay until I get my new PC133 memory? It seems to be working fine, but I'm wondering if it's going to be a probelm.
