Are Durons clock- or multiplier-locked?

[Hender]

I keep hearing about how overclockable the Durons are, and I'm getting a Duron this week and thought I'd give it a whirl. Are they clock- or mutiplier-locked, or can I play around with it to my heart's content?

They are multiplier locked, you need to unlock them by shorting the L1 bridges. Do a search on google Im sure youll find 30 articles on how to do so.

Not all Durons are though.

Check the L1 bridges if they are all intact. If they are not, They are locked.

Nah, I'm not that interested in O/C'ing. If they weren't multiplier-locked, I'd go 8x133 instead of 7.5x133 that I'm planning on doing. I'm selling the chip to my roommate for his Duron system he's building when the desktop Palaminos come out, so no accidental deaths are being planned. I think 7.5x133 will be just fine, but I hear I'll have to play with the voltage a bit to get it stable. True? If so, around how much should I up it?

"I hear I'll have to play with the voltage a bit to get it stable. True? If so, around how much should I up it?"
That depends on a few factors, my advice would be to max it benchmark it then lower it and repeat until the system wont run stable then up it to the last voltage that worked!

The problem will be that not all duron 750 will be able to do 7.5*133 and you might have to lower the multiplier to go to 133(or higher) fsb.

Here are a couple of articles from AnandTech. They are what enabled me to overclock...
