Advanced Memory Timing Setting
Users can assign different settings for particular channels of memory. This
has the advantage of individual memory parameter optimization, even using
the different memory specifications. When you set the detailed parameters,
and don’t know where to start with values, you can refer to the bottom of
the Current memory values list in the gray font block to set the appropriate
parameters for overclocking and not too far off the mark.
CPU Feature
The CPU Feature menu can be used to adjust settings such as Execute Disable
Bit, Virtualization Technology, Power Technology, C-State, etc. The Long/
Short Duration Power Limit setting in particular can be used to adjust CPU
TDP wattage limit. These two settings will affect the processor when it is
under heavy load but will not affect CPU ratio.
OC Ability Reference
Let us try out the Intel i7-2600K on the Z68A-GD80! Below are the overclock-
ing capabilities of the system.
• CPU Voltage: 1.520V
• CPU Ratio: 52
• Base Clock: 100MHz
Reference setting : 5200MHz

Max CPU Core Speed
Previous platforms based on the P55 and X58 chipsets can overclock up to
about 4GHz~4.2GHz with air cooling. The unlocked ratio of the LGA 1155 K
SKUs allows the new CPU to overclock even further. K CPUs depend on CPU
ratio to overclock, while using base clock to make finer adjustments. CPU
voltage can be controlled with the VCore Voltage setting. CPU I/O voltage
should also be adjusted in with respect to base clock. In addition, changing
Vdroop voltage to Low Vdroop will increase stability for systems under heav-
ing load. Extra care should be taken when using Low Vdroop, as voltage can
be erratic as well under heavy load.
