1.9 System Memory
The PCA-6188 has four sockets for 184-pin dual inline memory modules
(DIMMs) in two separated memory channels. It can operate with single
channel or dual channel modules. We recommend to use dual channel
mode to provide optimized performance.
All these sockets use 2.5 V unbuffered double data rate synchronous
DRAMs (DDR SDRAM). They are available in capacities of 128, 256,
512 and 1024 MB. The sockets can be filled in any combination with
DIMMs of any size, giving a total memory size between 128 MB and 4
GB.
Note: System resources such as PCI and AGP require physical
memory address locations that reduce available memory
addresses above 3GB. This may result in less than 4GB of mem-
ory being available to the operating system and applications.
