195-025 IBM RISC SYSTEM/6000 MODEL 39H

1MB or 2MB L2 Cache Memory (4045 and 4046) must be installed in pairs.

Memory must be installed in pairs. CPU memory and memory card must be of equal capacity. Because of space limitations caused by the regulator card and a large MCM on the new processor card, there is only one memory card slot.

The memory MB on the processor card must equal the memory MB on the memory card. There are 8 SIMM positions on both cards.Memory can be increased to 512MB by using 256MB Processor Card SIMM Memory and a 256MB Memory Card. A number of new feature codes have been created to handle memory granularity.
