Getting a new AXP1800, dont want to unlock

Well, after frying my 1700+, I just ordered an 1800+. Now a few questions come to mind. Without unlocking the multiplier, what kind of stable OC can I get on an ABIT KG7? My last cpu was OC'd to a 1900+, and my temps were ok on a swiftek heatsink w/ copper base. I have been able to get the FSB up to 141 and boot into XP Pro (I am also thinking of modding the retail XP heatsink for my Mobo to replace the existing northbridge fan/heatsink). I have also heard that adding a heatsink to the chip that regulates the clock speed will help in OCing with the fsb. This true?

I do not know if it will be the original color or one of those new green ones. Any difference between the 2?

I really dont want to blow another processor. So I am iffy on OCing this one, but Im a performance junkie. I feel the need for speed (and the cost of performance).

2100+ is good enough for me. As for my heatsink, I plan on selling the stock one or putting it on my friends PIII 800mhz so we can OC it. I got a Swiftech MCXC-370, Figure I can go pretty high with that (had my 1700+ running at 1.64ghz). I got a 60mm delt fan on it right now, but might move to a suno9n when I get some cash.
