Nice, yours seems to be a better core than mine, I haven't gotten it prime95 stable yet at 2.4GHz unless it's more like 1.75v (though I haven't tried it with my new fan, which dropped the temps about 5 degrees C).
I got my 2500+ @ 2.5 ghz but it only breaks the 2.3 barrier by ramping up crazy voltages (1.85 to reach 2.4 and like 1.95~2 for 2.5Ghz). my setup is on water btw.
