Amd Athlon 64 x 2 3800+ overlock

hi, I was wondering if it was possible to over clock my Amd Athlon 64 x 2 3800+ windsor in my hp dc 5750 SFF pc.

yes you can overclock that chip, but i do not think that HP has put options in the bios for overclocking. If they did in that model, sweet!. 

i can't seem to find it in the bois, is there any other program you might suggest to me for overclocking?
