I was browsing around on the AMDZone.com forums and say a reference to a site called http://www.buyoverclocked.com. If you go to there site you can see that they sell modified Duron 600 to run at 900mhz on any motherboard. It doesnt matter whether or not the board has a multiplier unlocker or not. I was real happy about this because I had no idea how to cut the bridges and that on the CPU. I think the chip cost around $135 US. I just thought I would mention it for anyone thats interested in getting a duron.
