Installing System Components 677 Align the notches in the processor with the socket keys on the ZIF socket.See Figure 3-9.8 With the release lever on the processor socket in the open position, alignthe processor with the socket keys and set the processor lightly in thesocket. See Figure 3-9.CAUTION: Do not use force to seat the processor. When the processor ispositioned correctly, it engages easily into the socket.9 Close the processor shield.10 Rotate the socket release lever down until it snaps into place. SeeFigure 3-9.11 Using a clean lint-free cloth, remove the thermal grease from the heat sink.12 Open the grease packet included with your processor kit and apply thermalgrease evenly to the center of the top of the new processor.CAUTION: Using excess thermal grease can cause grease to contact theprocessor shield, which can cause contamination of the processor socket.13 Install the heat sink. See "Installing the Heat Sink" on page 64.14 Replace the cooling shroud. See "Installing the Cooling Shroud" onpage 61.15 Close the system. See "Closing the System" on page 59.16 Reconnect the system and peripherals to their electrical outlets, and turnon the system.17 Press to enter the System Setup program, and check that theprocessor information matches the new system configuration. See "SystemSetup Options at Boot" on page 38.System MemoryYour system supports DDR3 registered DIMMs (RDIMMs). Single-, dual-and quad-rank DIMMs can be 800, 1066 or 1333 MHz.The system contains 18 memory sockets split into two sets of nine socketswith one set for each processor. Each nine-socket set is organized into threechannels of three memory sockets per channel.The maximum memory that is supported on your system varies according tothe types and sizes of memory modules being used:
