newbie with a Gig

Hey guys,
I have a Gig GA-7N400 Pro2 with 512MB of PC3200 DDR Athlon 2800+ OCed to 2.17 which is equivalent to a 3000+ and the only thing I did was bump up the FSB to 174MHz. I've been reading some of your posts and I've seen where you guys are changing the multiplier and so on. Where do I have the opton to change that and does anyone have the same config as mine and what do that have their machine configed too. Thanks

Gigabyte GA-7N400 Pro2
512MB Kingston PC3200 DDR
Seagate 80-Gig SATA
GeForce 5200 128MB DDR-Video
AMD Athlon 2800+ 2.08 (OCed to 3000+ 2.17)

p.s. I am afraid that bumping up the FSB without adjusting anything else is going to lock up my system.....again. Thanks for the help.

edwardaune,
If you look at page 3 of this guide there is a gigabyte specific overclocking guide Gigabyte New Owners Guide
