ROG Rampage II Extreme 3-15

UCLK Frequency [Auto]

Allows you to set the Uncore Clock Ratio (UCLK).

Conguration options: [Auto] [DDR3-1600MHz] [DDR3-2033MHz]

The UCLK Frequency conguration options vary with the DRAM Frequency

item settings.

QPI Frequency [Auto]

Allows you to set the QuickPath Interconnect (QPI) frequency.

Conguration options: [Auto] [4800MHz] [5866MHz] [6400MHz]

DRAM Timing Control

The items in this menu allow you to set the DRAM timing control features.

The conguration options for some of the following items vary depending on the

DIMMs you install on the motherboard.

1st Information: 6-6-6-15-4-36-6-3-16-4 (These values are auto-detected)

DRAM CAS# Latency [Auto]

Conguration options: [Auto] [1 DRAM Clock] – [15 DRAM Clock]

DRAM REF Cycle Time [Auto]

Conguration options: [Auto] [30 DRAM Clock] [36 DRAM Clock]

[48 DRAM Clock] [60 DRAM Clock] [72 DRAM Clock] [82 DRAM Clock]

[88 DRAM Clock] [90 DRAM Clock] [100 DRAM Clock] [110 DRAM Clock]

DRAM Frequency [Auto]

Allows you to set the DDR3 operating frequency.

Conguration options: [Auto] [DDR3-800MHz] [DDR3-1066MHz] [DDR3-1333MHz]

[DDR3-1600MHz] [DDR3-1866MHz] [DDR3-2133MHz]

The DRAM Frequency conguration options vary with the BCLK Frequency

item settings.

A very high DRAM frequency may cause the system to become unstable! If this

happens, revert to the default setting.
