1.8 System Memory (S1)
The PCA-6005-B has two sockets for 184-pin dual inline memory mod-
ules (DIMMs). All these sockets use 2.5 V unbuffered double data rate
synchronous DRAMs (DDR SDRAM) 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 2
GB. Use the following table to calculate the total DRAM memory within
your computer:
1.8.1 Supplementary information about DIMMs
Your PCA-6005-B can accept DDR SDRAM memory chips without par-
ity. Also note:
• The PCA-6005-B accpets PC1600 (DDR200), PC2100 (DDR266) or
PC2700 (DDR 333) DDR SDRAM, which can provide twice the per-
formance than the PC-133 SDRAM. The 168-pin SDRAM cannot be
used.
The PCA-6005-B does not support ECC (error checking and correction).
Memory modules with 9 SDRAM chips/side support ECC; modules with
8 chips/side do not support ECC.
