MSI Reminds You...

Change these settings only if you are familiar with the chipset.

DRAM Timing Selectable

Selects whether DRAM timing is controlled by the SPD (Serial Presence Detect) EEPROM on the DRAM module. Setting to By SPD enables DRAM timings to be determined by BIOS based on the configurations on the SPD. Selecting Manual allows users to configure the DRAM timings manually.

CAS Latency Time

This controls the timing delay (in clock cycles) before SDRAM starts a read command after receiving it. Settings: 2, 2.5, 3 (clocks). 2 (clocks) increases the system performance the most while 3 (clocks) provides the most stable performance.

Active to Precharge Delay

The field specifies the idle cycles before precharging an idle bank. Settings: 8, 7, 6, 5 (clocks).

DRAM RAS# to CAS# Delay

This field allows you to set the number of cycles for a timing delay between

3-12
