Ok I upped my my buss from 266 to 300x9 and left voltage stock. (THROUGH MY BIOS) I then loaded it with prime 95, im in Hawaii so I dont know the exact temp but its nice and cool right now. Im monitoring with cpuz, Asus Pc Probe, and core temp. My max readings was 77C from Core Temp and 64C from Pc Probe, I then stopped it.
Its idling right now at 55C Core Temp and 41C Asus PcProbe
Reverted back to stock settings 2.4 ghz its running prime 95 now with 77C Core Temp, 64C Pc Probe at 2.4 ghz stock. Thats the max of core 0
