Current FSB Frequency
This item displays the frontside bus (FSB) frequency. This is a display-only
item. You cannot make changes to this field.
Current DRAM Frequency
This item displays the memory (DRAM) frequency. This is a display-only item.
You cannot make changes to this field.
DRAM Clock (100 MHz)
This item enables you to manually set the DRAM Clock. We recommend that
you leave this item at the default value.
DRAM Timing (Manual)
Set this to the default value to enable the system to automatically set the
SDRAM timing by SPD (Serial Presence Detect). SPD is an EEPROM chip on
the DIMM module that stores information about the memory chips it contains,
including size, speed, voltage, row and column addresses, and manufacturer.
If you disable this item, you can use the following three items to manually set
the timing parameters for the system memory
DRAM CAS Latency (2.5)
Enables you to select the CAS latency time in HCLKs of 2/2 or 3/3. 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. The options are "2" and "2.5" default.
Bank Interleave (Disabled)
Enable this item to increase memory speed. When enabled, separate memory
banks are set for odd and even addresses and the next byte of memory can
be accessed while the current byte is being refreshed.
