"I picked up a Duron 700 today and have it overclocked at 1022MHz (9.5x107Mhz) and at 1.85v. I'm using the Abit KT7-RAID mobo and mushkin HSDRAM and have all settings maxed (4-way interleave, turbo, fast cpu, etc..). Temp is at 47c with seti and prime95 running using the Globalwin FOP32-1 heatsink/fan. I also have 3 extra case fans blowing on the mobo and my case is open. I could not believe that prime95 actually passed at this speed but it did

I have not tried higher YET, but probably will later today. A lot of bang for the buck ." ~3dgameman.com
The above info is at my site - also a few pics of sisoft results and wcupid speed and temp.
