Coolermaster 80x60 heatsink for OC?

[Kazuo]

Hey, I've got an 80x60 heatsink from Coolermaster (I can't remember which one it is, I bought it like a year and a half ago). And a 60x60x25 quiet fan from OCZ (about 5000rpm, 25cfm). I've also got a Duron 750MHz sitting around, and I just ordered a Transcend KT133 board. I plan on unlocking the multiplier (since I'm not going to be able to go to 133/33 on the Transcend, most likely). What would you say would be a safe, stable overclock using these? I've got some AS2 sitting around as well, though I doubt that'll affect the results very much. My guess is that 900MHz is conservative. I'm not planning on jacking up the voltage past 1.75V (which I figure is pretty safe since the Athlons use it).
Any thoughts?

Does the Transcend board allow multiplier manipulations, then? If so, go for it. I use a CM 80 x 60 heatsink to OC my 1600+, with about a 6000rpm 60mm x 15mm fan. I'm guessing it puts out no more than 30cfm, and I can go to 1750MHz with it. Ok, so I did pull out some fine sandpaper and lap it until the base was flat...

Yeah, I'm gonna have to do some lapping too, I suspect, to get rid of the last of that stubborn thermal pad. Silly Coolermaster.
I think I heard that it supports Vcore and multiplier adjustments. I figure going from 750 to 900 (maybe 950 or 1000) is pretty worthwhile, since it's a free speedup.
So, if you set the processor too high and it doesn't POST, how do you get it back up and running? Do you have to clear the CMOS? Or can you just erase the pencil and force it to run at 750 again?
You can really tell I haven't done a whole lot of overclocking

Some Durons are already factory-unlocked. If that's the case, and the default CMOS setting is to look at the CPU for the multiplier, then if you override the CPU's default multiplier in the BIOS and it cannot POST, then resetting the CMOS would restore the default "look at the CPU's choice" setting and you would be back in business. Is yours factory-unlocked (all L1 bridges connected)?

To be honest... no clue. It's 140 miles away back home. I'll find out during Thanksgiving break I guess.
When I got it, all I noticed was that it was a 750 and I was pleased because my friend told me it was a 700. Not a huge difference, but still nice to know.
