These items define critical timing parameters of the motherboard. You should leave the
items on this page at their default values unless you are very familiar with the technical
specifications of your system hardware. If you change the values incorrectly, you may
introduce fatal errors or recurring instability into your system.

DRAM Timing Control (By SPD)
Enables you to select the CAS latency time in HCLKs of 2, 2.5, or 3. The value is set at the
factory depending on the DRAM installed. Do not change the values in this field unless you
change specifications of the installed DRAM or the installed CPU.
• DRAM CAS Latency (2.5T): This item controls the timing delay (in clock
cycles) before the DRAM starts a read command after receiving it.
• RAS Active Time (tRAS) (6T): This item allows you to set the amount of time
a RAS can be kept open for multiple accesses. High figures will improve
performance.
DRAM Timing Control [By SPD]
DRAM CAS Latency 2.5T
RAS Active Time (tRAS) 6T
RAS Precharge Time (sRP) 3T
RAS to CAS Delay (tRDC) 3T
