Intel G4H875-C, G4H875-B CAS Latency Time, Active to Precharge Delay, Dram RAS# to CAS# Delay

BIOS Setup

Manual If you want your system to run at a performance better than the one “by SPD”, select “Manual” then select the best option in the “CAS Latency Time” to “DRAM RAS# Precharge” fields.

3.1.3.2 CAS Latency Time

This field is used to select the local memory clock periods.

3.1.3.3 Active to Precharge Delay

The options are 5, 6, 7 and 8.

3.1.3.4 DRAM RAS# to CAS# Delay

The options are 2, 3 and 4.

3.1.3.5 DRAM RAS# Precharge

This field controls RAS# precharge (in local memory clocks).

3.1.3.6 Memory Frequency For

This field is used to select the memory clock speed of the DIMM.

The system board supports DDR266, DDR333 or DDR400 when using 800MHz FSB CPU.

DDR333 will run at 320MHz memory frequency when used with 800MHz FSB CPU. Under such circumstance, make sure this field is set to Auto or DDR320.

Refer to chapter 1 (System Memory section) for detailed specifica- tion of the memory supported by the system board.

3.1.3.7 System Bandwidth

The options are HPS3, MPS1, MPS2, LPS1, LPS2 and LPS3.

LPS denotes Low Bandwidth for overclocking.

MPS denotes Middle Bandwidth for overclocking.

HPS denotes High Bandwidth for overclocking.
