Hi guys! i have an pretty old asus u3sg laptop and i want to upgrade the cpu (current cpu is intel core 2 duo t8300 2.4ghz)
while ago i tried to put t9600 2.80 ghz , but my bios didnt recognize it. i have tried to test it with single ram , reset bios etc. but it didnt work
Bios version: Amibios 308 (latest version)
Socket: socket pga478
Ive tried to email the asus support but i didnt understand how to write the serial number of my laptop (it was so hard lol)
