can someone give me a hand to add new microcodes(45nm) in my bios??
my board is GA-8I865PE775-G-RH(6.6)
my cpu is qx9650 and e8400
when i use qx9650 the bios will show ukown ID and the speed is 200X6 and even i change the multiplier in bios it will not work in other multiplier(only 6)
then i use this cpu in windows the cpu-z show qx9650 but the speed is 1200

Gigabyte retail boards only 8I865PE775-G-RH up to rev 4.9 but there is a GA-8I865GME-775-RH (rev. 6.6) so which one is it?
