Processor

The system includes two processor boards capable of supporting up to four Pentium Pro processors (two per board). Each processor board has two processor sockets. The board contains DC to DC converters for power to each processor (Figure 2-4, A and B). The Pentium Pro processors plug into a Zero Insertion Force (ZIF) sockets on this board (Figure 2-4, C and D). An optional second Pentium Pro processor enhances performance and enables symmetric multiprocessing (SMP). Both processors access the same memory and I/O space and tasks can run on either CPU if your operating system (OS) supports SMP.

Memory

The memory board contains sixteen 168-pin DIMM sockets (Figure 2-5). The minimum system configuration includes 64 MB (using two 32 MB DIMMs) of system memory. 16 DIMM sockets allow for system memory expansion to 4 GB (using sixteen 256 MB DIMMs). ECC generation/checking is provided for detection and correction of memory errors.

Note: Only use DIMMs approved for use in this server system. Call your customer service representative for information.
