Installing A Memory Dimm Pair; Memory Slots On System Board - Compaq AlphaServer 1200 User Manual

7.4 Installing a Memory DIMM Pair

Remove the top cover and side panel to access the system board. After you have
re-installed the memory card, verify the installation by issuing the show memory
command from the SRM console or display the memory configuration from the
AlphaBIOS console. Figure 7–6 shows the memory slots on the system board.
Configuration Rules
•
There are two riser cards; one DIMM of each pair is installed in the same slot on
each riser card (see Figure 7–7).
•
Both DIMMs in a memory pair must be the same size, either 64 MB or 256 MB.
•
The larger memory pair (256 MB) must be installed in riser card slot 0.
•
Other memory pairs must be the same size or smaller than the first memory pair.
•
Memory pairs must be installed in consecutive slots. The first pair goes into slot
0, the second pair into slot 1, and so on.
•
If a 64-MB DIMM pair is installed in slot 0, the memory configuration cannot
exceed 4 DIMM pairs.
