Well Now is working, how? i do not know, but is working. I found unlocking my 3rd and 4th cores in windows XP 32b i got some freeze moments that make me reboot. I had win7 installed on my HD and with that OS i do not have those freeze issues, so as i usually use XP as my main OS i decided to no unleash the beast, that way i had not freezing problems. My CPU temp is fine as the latest Bios the Vcore is 1.32 so is a little bit colder than using 904. I plan to use as my main OS win7 64 to unleash all cores...Keep in touch
