"If you insist on doing it, plan on spending about $75 for a single 256MB stick"
if you are open to eBay purchasing, you can get TWO low density 256mb PC133 sticks for about $50, before shipping. if you want to boost graphics performance too, DEFINITELY get a 64mb GFX card, like a Radeon 8500 or similar. i have a Radeon 9200 128mb in my rig:
1.0ghz P3
512mb PC133
120gb WDC 7200rpm 8mb cache hard drive
ATI Radeon 9200 AGP 128mb overclocked
you are lucky your board will let you over clock, though, mine wont. LOL.
when you say max multiplier is 12.5x what it actually is now? anyway, yeah i would set the FSB at 145-150mhz.
If you can stay calm, while all around you is chaos...then you probably haven't completely understood the seriousness of the situation.
