System Memory
The PCA-6010 has two sockets for 240-pin dual inline memory modules (DIMMs) in
two memory channels.
All these sockets use 1.8 V unbuffered double data rate synchronous DRAMs (DDRII
SDRAM). They are available in capacities of 256, 512, 1024 and 2048 MB. The sock-
ets can be filled in any combination with DIMMs of any size, giving a total memory
size between 256 MB and 4 GB.
1.9.1
CPU FSB and memory speed
The PCA-6010 can accept DDR2 SDRAM memory chips without parity. Also note:
The PCA-6010 accepts DDR2 533/667MHz SDRAM. The PCA-6010 does NOT sup-
port ECC (error checking and correction).

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. Slowly slide the DIMM module along
the plastic guides on both ends of the socket. Then press the DIMM module right
down into the socket, until you hear a click. This is when the two handles have auto-
matically locked the memory module into the correct position of the DIMM socket. To
remove the memory module, just push both handles outward, and the memory mod-
ule will be ejected by the mechanism in the socket.

Cache Memory
The CPU that PCA-6010 supports built-in 4 MB (for Core™ 2 Duo), 2 MB (for Pen-
tium Dual-Core CPU), 2 MB (for Pentium 4 CPU), 512 KB (for Celeron D CPU) full-
speed L2 cache. The built-in second-level cache in the processor yields much higher
performance than conventional external cache memories.
