4Current FSB Frequency
The setting for this field will be automatically selected by the BIOS.
4Current Dram Frequency
The setting for this field will be automatically detected by the BIOS. The
value that is selected in derived from the RAM clock.
4DRAM Clock
When you press enter you will have three options:
By SPD :The BIOS will automatically detect the actual DRAM Clock.
100 MHz :The DRAM clock speed will be PC1600 (100 MHz DDR).
133 MHz :The DRAM clock speed will be PC2100 (133 MHz DDR).
166MHz :The DRAM clock speed will be PC2700 (166 MHz DDR).
4DRAM Timing
This field enables/disables you from selecting the values for following six
fields manually. These (six) fields determine the DRAM read/write timing. If
you select By SPD then those fields will be automatically configured by the
system BIOS. (The performance parameters of the installed memory chips
(DRAM) determines the value in those fields.)
