Great Mob, my 1.6P4 is running 157fsb 2512Mhz, memory 4/5 2.5 2 2 6 2 which gives me the best performance. It will run at 161fsb 2576Mhz but the memory has to run at 1/1 and the performance is less. V core is 1.7v, memory is kingmax 2700. Only problem was the game port was unstable useing flight...
