3.1.2 Memory Modules
The main memory capacity is adjustable via installation of the appropri-
ate memory modules.
The qualified memory modules depend on the SPARC/CPCI-52x(G) pro-
cessor frequency. They are given in the following table.
Caution
Do not install SPARC/MEM-50x and SPARC/MEM-50x-5 memory
modules on the same board, otherwise system malfunction may oc-
cur.
In the following it will be refered to all memory module types as
SPARC/MEM-50x.
The Base-520(G) can hold 1 to 4 memory modules providing up to
1 GByte DRAM capacity. 1 memory module can carry 2 memory banks.
Note: At least 1 lower memory module MEM-50L is required.
See the following figure for the memory module numbering scheme:
• Memory modules #1 and #2 are located in the first CompactPCI slot
the SPARC/CPCI-52x(G) occupies.
• Memory modules #3 and #4 are located in the second CompactPCI slot
the SPARC/CPCI-52x(G) occupies.
