I just got my Z77 sabertooth 2 days ago, I found that under the Ai Tweaker Menu, 3 options are missing. They are "Turbo Ratio", "internal PLL Overvoltage" and "CPU Bus speed : DRAM speed ratio mode".
Even I upgrade my BIOS, or Clear CMOS with jumper, these three options are still missing.
My situation just like this guy with his Maximus V Gene
CPU: i5 2500k
Mother Board: ASUS Z77 Sabertooth
RAM: 2x4GB Corsair Vengeance DD3 1866
Graphic card: ASUS ATi HD7870DirectCUII
SSD: Samsung 830 128GB
Hope someone can help. Thank you.
