1-8 System OverviewPentium III ProcessorThe system board includes two FC-PGA sockets to accomodate up to two Pentiun III.The Pentium III processor includes the processor core with an integrated 16 KBprimary (L1) cache and a secondary (L2) cache. The processor implements the MMX™technology and the processor’s numeric coprocessor significantly increases the speed offloating-point operations.The processor external interface operates at a maximum of 133 MHz. The second-levelcache is located on the substrate of the processor. The cache includes burst pipelinedsynchronous static RAM (BSRAM). The L2 cache is offered with error correcting code(ECC) that operates at the core clock rate.System MemoryThe system board contains four 168-pin DIMM sockets. Memory is partitioned as eightbanks of SDRAM DIMMs, each providing 72 bits of noninterleaved memory (64-bitmain memory plus ECC). Your system may include from 64 MB to 2 GB of memory,using up to four 168 pins unbuffered DIMMs.System memory begins at address 0 and is continuous (flat addressing) up to themaximum amount of DRAM installed (exception: system memory is noncontiguous inthe ranges defined as memory holes using configuration registers). The system supportsboth base (conventional) and extended memory.I/O Expansion SlotsThe server's expansion capabilities meet the needs of file and application servers forhigh performance I/O by providing PCI local bus connectors.The system board has five PCI connectors (2 half length and 3 full length).PCI features:n Bus speed up to 33 MHzn 32-bit memory addressingn 3.3 V / 5 V signaling environmentn Burst transfers of up to 133 Mbpsn 8-, 16-, or 32-bit data transfersn Plug and Play readyn Parity enabled.
