I have a p2 450mhz slot 1 pc I just built with win98. The only ram i had avaiable is 2 sticks of sdram @ 133mhz. Knowin that my bus speed on processor is 100mhz...will that ram be the reason my pc gives me unexpected program errors? Or should i go and get sdram at 100mhz? Also, the only operating system it will take is windows 98. Xp never gets past the Hardware installation when it detects my Geforce4 420mx 64mb video card before it freezes up. (didnt' know if that would help)
