|"Mobo: Gigabyte 81848P-G"|
Actually, it's 8i848P-G.
You may be able to get it up to about 3.5GHz but your RAM is going to hold you back from going any further. You could underclock the RAM to allow a higher CPU overclock, but that defeats the purpose. Also, the Prescott has heat issues so the higher you overclock, the hotter it will get. My advice is to just leave it be.
