Asus P5GC-MX manual Dram Frequency Auto, Configure Dram Timing by SPD Enabled, Hyper Path 3 Auto

DRAM Frequency [Auto]

Allows you to set the DDR2 operating frequency. Configuration options: [Auto] [400 Mhz] [533 Mhz]

Selecting a very high DRAM frequency may cause the system to become unstable! If this happens, revert to the default setting.

Configure DRAM Timing by SPD [Enabled]

When this item is enabled, the DRAM timing parameters are set according to the DRAM SPD (Serial Presence Detect). When disabled, you can manually set the DRAM timing parameters through the DRAM sub-items. The following sub-items appear when this item is Disabled.

Configuration options: [Disabled] [Enabled]

DRAM CAS# Latency [5 Clocks]

Controls the latency between the SDRAM read command and the time the data actually becomes available.

Configuration options: [6 Clocks] [5 Clocks] [4 Clocks] [3 Clocks]

DRAM RAS# Precharge [4 Clocks]

Controls the idle clocks after issuing a precharge command to the DDR SDRAM. Configuration options: [2 Clocks] [3 Clocks] [4 Clocks]

[5 Clocks] [6 Clocks]

DRAM RAS# to CAS# Delay [4 Clocks]

Controls the latency between the DDR SDRAM active command and the read/write command. Configuration options: [2 Clocks] [3 Clocks] [4 Clocks] [5 Clocks] [6 Clocks]

DRAM RAS# Activate to Precharge [15 Clocks] Sets the RAS Activate timing to Precharge timing. Configuration options: [4 Clock] [5 Clocks] ~ [18 Clocks]

DRAM Write Recovery Time [4 Clocks]

Sets the DRAM Write Recover Time. Configuration options: [2 Clocks] [3 Clocks] [4 Clocks] [5 Clocks] [6 Clocks]

Hyper Path 3 [Auto]

Sets this item to enabled to reduce bottlenecks of memory bandwidth. Sets it to disabled for safe mode. Configuration options: [Disabled] [Enabled] [Auto]

DRAM Throttling Threshold [Auto]

Allows you to enable DRAM Thermal Throttling to make your system more stable. Configuration options: [Disabled] [Auto]
