Content
The Netfinity 8500R includes a single memory card with the ability to support up to 8GB of memory. Model 8681-4RY contains two RDIMMs standard, other models contain four. For memory installation of greater than 8GB, Nefinity 8500R Memory Expansion Card (28L4454) is required. Installation of memory on systems containing a single memory card (standard on all models) has no restrictions on size or placement. When Netfinity 8500R Memory Expansion Card (28L4454) is installed, the memory RDIMM in each socket of Card A must match the RDIMM in the same socket on Card B. To enable cache liine interleaving, both memory cards must be installed and configured identically.
