Fsb?

Ok I'm a newbie so flame on I've built a few systems that run fine but never oc'd. I'm confused by the jumpers on some of these asus boards. The manual say the board is made for 333 fsb so I set the jumpers for that, when it boots it says the multiplier is 166 mhz. Now to oc, I'm supposed to raise the fsb above 166 in bios? But I thought the board was set to run at 333? I've been reading up on this for weeks but cant figure this part out??? I know you guys can help me out.....go easy on the newbie

ok I think I just figured it out, the board fsb is really half what you set it for? So if I set the board to 333 (with the jumpers) it's actually running at 166? 12.5x166=2075 Thats really dismal performance for a 2800 processor isnt it?

lol, sorry, that's just funny, you put me in my state of mind when i first started, welcome to your new addiction, and welcome to the forums
