1-8 System OverviewXeon™ ProcessorsDepending on system configuration, each system includes one or two Intel Xeon2.00GHz or 2.80GHz processors. Each processor plugs into a INT3/FCPGA socketpackage. The processor includes a 512K cache. When two processors are installed, bothprocessors must be of identical bus and core speed.The processor external interface operates at a maximum of 400MHz. The second-levelcache is located on the substrate of the processor cartridge. The cache includes burstpipelined synchronous static RAM (BSRAM).System MemoryThe system board contains six 168-pin DIMM sockets. Memory is partitioned as threebanks of registered SDRAM DIMMs (DDR200 compatible) that must be populated inpairs, each providing 72 bits of buffered two-way interleaved memory (64-bit mainmemory plus ECC). Your system may include from 256 MB to 6 GB of memory, usingup to six 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 systemsupports both base (conventional) and extended memory.PCI Riser SlotsThe server's expansion capabilities meet the needs of file and application servers forhigh performance I/O by providing PCI expansion slots.The system board has three full-length, full height 64-bit/100MHz PCI-X slots (riserslot B) and three low profile 64-bit/100MHz PCI slots (riser slot A).Riser slot A provides the following features:! Bus speed up to 100MHz! 184 pin, 5 volt keyed, 64-bit expansion slot connector! Support for a 3-slot PCI riser card! Support for only low profile PCI cardsRiser slot B provides the following features:! Bus speed up to 100 MHz! 184 pin, 5 volt keyed, 64-bit expansion slot connector! Support for a 3-slot PCI riser card! Support for only full length, full height PCI cards.
