Ok my friend got a Asus Rampage II Extreme motherboard and an i7 980x with 6GB (3x 2GB) Corsair D. GT from Newegg. And when he entered windows 7 bringing up the CPUz and Windows 7 System properties it shows 2 different GHZ. On CPUz it shows 4.5Ghz and on Windows 7 System Properties it shows 3.8 Ghz and plus the task manager it shows only 4 cores. Was it suppose to show 6 Cores? Why it only shows 4? my friend try go into the Asus Rampage II Bios setting and it is very hard and he do not know which setting to change in order for Cpuz and Windows 7 System properties to shows the same Ghz and for Task manager to show 6 cores. Anyone know the solution for this?
