Intel P III Slot A 700E Cco step @ 1050 mhz default voltage with Alpha P3125 (i think ) in Abit BE6-II R 2.0 / Hercules GF2 MX 100% stable @ 100 mhz AGP , this speed is with 28/Celsius under load , realy awesome chip , i still hawe that computer , my wife use dayly . Never try to occ more but is a damn speed increase from original 700 mhz @ 100 FSB , this was the best CPU i ever bought .
I had also a P III 600E Slot A Cco step also wich did 900 mhz @ default voltage .
My worst Slot CPU was a P III 700E who dis 840 mhz @ 1.8v , it was a Cbo step .
