Current 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.

DRAM Clock
When you select By SPD The following menu will pop up:
100 MHz
133 MHz
By SPD
If you select 100 MHz the DRAM clock speed will be PC1600 (100 MHz DDR). If you
select 133 MHz the DRAM clock speed will be PC2100 (133 MHz DDR). If you select
By SPD the BIOS will automatically detect the actual DRAM Clock.

DRAM Timing
This field determines the DRAM read/write timing. The performance parameters of the
memory chips (DRAM) you have installed will determine the value in this field. Do not
change the value from the factory setting unless you install new memory that has a
different performance rating than the original DRAMs.
!
SDRAM Cycle Length
Before SDRAM can execute a read command that it receives, there is a delay time,
which is measured in clock cycles (CLK). The lower the delay time the faster the exe-
cution of commands will be. It is therefore desirable to minimize this cycle length.
Some memory modules are unable to deal with short delay times. We recommend
that you set this delay time between 2.5 and 3 CLK’s (the default is 2.5). If your sys-
tem becomes unstable we recommend that you increase the delay time.

AGP Aperture Size
This field selects the size of the Accelerated Graphics Port (AGP) aperture. The aper-
ture is a portion of the PCI memory address range dedicated for graphics memory
address space. Host cycles that hit the aperture range are forwarded to the AGP with-
out any translation. The default is 64MB. You may increase this memory when you
need to have faster access for 3D graphics applications (e.g. games).
