The 82440ZX motherboard supports 168 pins DIMM of 4MB, 8MB,
16MB, 32MB, 64MB, 128MB and 256MB to form a memory sie between
8MB to 256MB(SDRAM).
82440ZX chipset provides “Table-Free” function, but do remember
that the DRAM must be 3.3V Unbuffered and 4 clock type. User can
use two DIMMs without any limit but if uses three DIMMs then must
follow the rules below:
NOTE: ONLY SINGLE SIDE SDRAM CAN BE PLUGGED WHEN DIMM2/DIMM3
SIMULTANEOUSLY USED.

the configuration values of this option when you change your system hardware
configuration or the configuration stored in the CMOS memory gets lost or
damaged.
Run the Standard CMOS Setup as follows:
1. Choose “STANDARD CMOS SETUP” from the Main Menu and a screen
with a list of options will appear.
2. Use one of the arrow keys to move between options and modify the

SDRAM RAS-to-CAS
Delay
If an insufficient number of cycles is allowed for the RAS to
accumulate its charge before DRAM refresh, the refresh
maybeincompleteandthe DRAM mayfailtoretaindata. Fast
gives faster performance. Slow gives more stable
performance.
This field applies only when synchronous DRAM is installed
in the system.
Ther choice: 2, 3 (default).
SDRAM RAS Precharge
Time
Use the default setting.SDRAM Precharge
Control
When synchronous DRAM is installed, the number of clock
cycles of CAS latency depends on the DRAM timing. Don’t
reset this field from the default value specified by system
designer.
The choice: 2T, 3T.
