About the Memory Modules

VIS provides high levels of multimedia performance, including real-time video compression and decompression and two streams of MPEG-2 decompression at full broadcast quality with no additional hardware support.

The Sun Fire V490 server employs a shared-memory multiprocessor architecture with all processors sharing the same physical address space. The system processors, main memory, and I/O subsystem communicate via a high-speed system interconnect bus, operating at a clock rate of 150 MHz. In a system configured with multiple CPU/Memory boards, all main memory is accessible from any processor over the system bus. The main memory is logically shared by all processors and I/O devices in the system.

For information about memory modules and memory configuration guidelines, see “About the Memory Modules” on page 28.

The Sun Fire V490 server uses 3.3-volt, high-capacity dual inline memory modules (DIMMs). The DIMMs are built with synchronous dynamic random access memory (SDRAM) chips that operate at a 75-MHz clock frequency. The system supports DIMMs with 512-Mbyte and 1-Gbyte capacities.

Each CPU/Memory board contains slots for 16 DIMMs. Total system memory ranges from a minimum of 8 Gbytes (one CPU/Memory board with eight 512-Mbyte DIMMs) to a maximum of 32 Gbytes (two boards fully populated with 1-Gbyte DIMMs).

Within each CPU/Memory board, the 16 DIMM slots are organized into groups of four. The system reads from, or writes to, all four DIMMs in a group simultaneously. DIMMs, therefore, must be added in sets of four. FIGURE 3-1shows the DIMM slots and DIMM groups on a Sun Fire V490 CPU/Memory board. Every fourth slot belongs to the same DIMM group. The four groups are designated A0, A1, B0, and B1.
