LOL, that sucks about the screws. Don't blow it up on the first night trying to get 5GHz
I messed around with AI Booster on the 630. I still don't like it that much. It has a real problem reading -C CPU temps and unlike SetFSB, leaves the OC where it was last when rebooting, but there's probably no other way to get >350FSB with 14x. I very much doubt you'll be able to boot anywhere near 5GHz just using BIOS settings, so you'll need to use something to get bump up FSB once you hit the desktop.
It IS possible to get 14x on the 0304 BIOS with the 600s and that will open up the use of SetFSB since that's the only BIOS it works on. Unfortunately, the 0304 is definitely does not OC as well as 0509 or 0512 and those only leave AIB for cranking up FSB in Windows.
One other this I noticed about AIB is that if you try to raise FSB in too big of steps, it will require a restart to take effect. If I boot at at 275FSB and use AIB to raise it to 330, it will want to restart, but if I boot at 275 and then increase the FSB to 330 in steps of 10, they no restart is required.
That being said, I would still boot via BIOS as high as you can....or at least over 266FSB. Thing change at 266 (1066FSB) and if you start <266FSB and end up >266FSB I think it will require a restart regardless to pick up the new dividers and stuff.
Make sure your DDR is set to something that it can handle when you raise the FSB manually. If you're just playing with CPU max clock to start, I'd just set it to 1:1 and go to work. I've made the mistake of doing that and couldn't figure out why it would lock up until I realized that DDR1200 just wasn't happening...LOL.
