3.3 System Memory Configuration
The AV18 mainboard has three 168-pin DIMM sockets that allow you to
install from 16MB up to 1.5GB of system memory with PC66/100/133
SDRAM (Synchronous DRAM). Each DIMM (Dual In-line Memory Module)
socket can accommodate 16MB, 32MB, 64MB, 128MB, 256MB and
512MB 3.3V single or double side 64 or 72-bit wide data path SDRAM
modules.
The AV18 mainboard supports data integrity algorithms including EC (Error
Checking) and ECC (Error Checking and Correction) in the memory array. In
EC mode, single and multiple bit error detection is provided. In ECC mode,
when the memory is being read from DRAM, the AV18 provides both error
checking and correction of the data.
Install Memory:
Install memory in any or all of the banks and in any combination, as follows.
Note:
You do not need to set any jumper to configure memory since the
BIOS utility can detect the system memory automatically. You can
check the total system memory value in the BIOS Standard CMOS
Setup menu.
Upgrade Memory:
You can easily upgrade the system memory by inserting additional SDRAM
modules in available DIMM banks. The total system memory is calculated by
simply adding up the memory in all DIMM banks. After upgrade, the new
system memory value will automatically be computed and displayed by the
BIOS Standard CMOS Setup menu.
