Step 3 Memory Optional - Compaq DA-64CAA-DA - AlphaServer - ES40 Model 2 Specification

QuickSpecs
Systems/Options
Step 2 Additional CPU Modules Optional
One CPU included, three additional CPUs are supported
From:
EV67 667-MHz CPU
EV6 500-MHz CPU

Step 3 Memory Optional

Systems include one memory option
Model 1 systems supports four memory options (total of 16 DIMMs)
Model 2 systems support eight memory options (total of 32 DIMMs see Note below)
Memory performance considerations: Interleaved operations reduce the average latency and increase the memory throughput over non-
interleaved operations. With one memory option (4 DIMMs) installed, memory interleaving will not occur. With two identical memory
options (8 DIMMs) installed, memory read-write operations are two-way interleaved. With four identical memory options (16 DIMMs)
installed, memory read-write operations are four-way interleaved, maximizing memory through-put
