The server combines: v Impressive performance using an innovative approach to SMP The server supports up to two Pentium III microprocessors. The server comes with one microprocessor installed; you can install an additional microprocessor to enhance performance and provide SMP capability. v Large system memory The memory bus in the server supports up to 4 GB of non-interleaved system memory. The memory controller provides error correcting code (ECC) support General information 5
