Advanced Memory Timing Setting

After selecting DRAM Timing Mode, the Advanced DRAM Configuration menu can be used to adjust memory settings. The left side shows the memory’s default settings while the right side can be used to change the memory’s timing.

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

Now, taking the P67A-GD80 (B3) mainboard with the Intel’s latest Core i5 2500K CPU as an example, we will set Core Speed and Memory Frequency as overclocking items to introduce some points and notices to users for refer- ence.

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.

Reference setting : 5200MHz

• CPU Voltage: 1.58V

Base Clock: 100MHz

• CPU Ratio: 52

Internal PLL Overvoltage: Enabled
