1.9 System Memory
The PCE-5130 has two sockets for 240-pin dual inline memory modules (DIMMs) in
two memory channels.
Both sockets use 1.8 V unbuffered double data rate synchronous DRAMs (DDR
SDRAM). They are available in capacities of 256 MB, 512 MB, 1024 MB and 2 GB.
The sockets can be filled in any combination, with DIMMs of any size, giving a total
memory size between 256 MB and 4 GB.
The PCE-5130 can accept DDR2 SDRAM memory chips without parity. Also note
that the PCE-5130 accepts DDR2 400/533/667 MHz SDRAM, and DDR2 SDRAM.
The PCE-5130 does NOT support ECC (error checking and correction).
1.10 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket are in the
“open” position, i.e. the handles lean outward. Insert the DIMM module into the plas-
tic guides on both ends of the socket. Then press the DIMM module well down into
the socket, until the two handles lock the memory module into position in the socket.
To remove the memory module, just push both handles outward, and the memory
module will be ejected.
1.11 Cache Memory
CPUs supported by PCE-5130 have 4 MB, 2 MB and 1 MB L2 cache memory sizes.
