Upgrading Your System

AlphaServer 1000 to 1000A Upgrade 1-11

Removing the Memory Modules

Remove memory SIMMs from system (see Figure 7) and install them in the

AlphaServer 1000A 5/xxx system (see Figure 8).

Note that the ECC bank SIMM is not used in 5/xxx systems. The ECC bank is left

unfilled. All AlphaServer 1000A 5/xxx memory bank SIMMs have error detecting

and correcting logic (ECC functionality) built in.

Caution:

The ECC SIMM is not compatible with memory bank SIMMs. Do not

place the ECC SIMM in a memory bank of the new AlphaServer 1000A 5/xxx

system. The SIMM in the ECC bank should be left in the AlphaServer 1000 4/2xx

system and returned to Digital.

Be sure to comply with the following memory configuration rules when adding

memory:

• Bank 0 must contain a memory option (4 SIMMs, 0, 1, 2, and 3)

• A memory option consists of 4 SIMMs (0, 1, 2, and 3)

• All SIMMs within a bank must be of the same capacity
