15 Turn on the system and attached peripherals. 16 Test the drive by running system diagnostics (optional). See "Running the System Diagnostics" on page 181. System Memory Your system supports DDR3 registered memory modules (RDIMMs) or ECC unbuffered memory modules (UDIMMs). Single and dual-rank memory modules can be 1067- or 1333-MHz, and quad-rank memory modules can be 800-MHz and 1067-MHz. The system contains eighteen memory sockets split into two sets of nine sockets, one set per each processor. Each nine-socket set is organized into three DIMMs for each channel. The first socket of each channel is marked with white release levers. The maximum memory that is supported on your system varies according to the types and sizes of memory modules being used: • Single-rank and dual-rank RDIMMs of sizes 2-GB, 4-GB, and 8-GB (when available) are supported for a total of up to 144 GB. • Quad-rank RDIMMs are supported for a total of up to 96 GB. • 1-GB and 2-GB UDIMMs are supported for a total of up to 24 GB. General Memory Module Installation Guidelines To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory. NOTE: Memory configurations that fail to observe these guidelines can prevent your system from starting or producing any video output. • RDIMMs and UDIMMs cannot be mixed. • Except for memory channels that are unused, all populated memory channels must have identical configurations. • In a dual-processor configuration, the memory configuration for each processor must be identical. • Memory modules of different sizes can be mixed within a memory channel (for example, 2-GB and 4-GB), but all populated channels must have identical configurations. 98 Installing System Components
