Bypass Access
This technology can provide users with the function of increasing the sys- tem performance. The default value is [Disabled]. It will only work when you use FSB800 CPU and DDR400 DRAM at the same time; otherwise, this option will be hidden.
DRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assigns appropriate frequency automatically. You may also select other value as operating frequency: [133MHz (DDR 266)], [166MHz (DDR 333)], [200MHz (DDR 400)].
Flexibility Option
The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled].
Configure DRAM Timing by SPD
Select [Enabled] will configure the following items by the contents in the SPD (Serial Presence Detect) device.
DRAM CAS# Latency
Use this item to adjust the means of memory accessing. Configuration options: [Auto], [2.5], [2], and [3].
DRAM RAS# Precharge
This controls the idle clocks after a precharge command is issued. Configuration options: [4], [3], and [2].
DRAM RAS# to CAS# Delay
This controls the latency between the DRAM active command and the read / write command. Configuration options: [4], [3], and [2].
DRAM Precharge Delay
This controls the number of DRAM clocks for RAS minimum. Configura- tion options: [8], [7], [6], and [5].
