hrmm, i doubt it dood. 2.4c's can go to about 3.5 max, 3.6 if your VERY lucky on air cooling. some people are doing it on stock vcore's. it just depends on luck of the draw i guess. i have a 2.6c and i cant even do 3.25ghz / (250fsb/1000fsb)
i dont even think the celeron's oc THAT good, you might get 3.5ghz though, which is pretty damn awesome.
