Add CPUs and Heatsinks to X8440 Server Module

This topic describes how to add two CPUs and two heatsinks to the X8440 Server Module to upgrade the Server Module to a four-CPU configuration. You need to purchase a CPU Option kit to upgrade to a four CPU configuration.

Before You Begin

What to Do

To add CPUs and heatsinks to SKT0 (CPU0) and SKT1 (CPU1) on the X8440 Server Module follow these steps:

Caution

Some AMD Opteron CPUs are released as Special Editions, which might differ in wattage from non-Special Edition versions of the CPU. Do not mix Special Edition CPUs with non-Special Edition versions. Ensure that all CPUs in the server have the same part number.

  1. Ensure that the CPU socket release lever and retainer plate are in the fully open position.

  2. Align and gently insert the CPU onto the pins in the socket.

    Use the alignment keys in the CPU socket to match the alignment notches on the sides of the CPU.

    Caution

    The pins on the CPU socket are very fragile. If the CPU is correctly aligned, it will enter the CPU socket with little or no resistance. If you feel more than minimal resistance, stop and recheck the alignment. Forcing a misaligned CPU into the CPU socket could damage both devices.

  3. When the CPU is fully seated in the socket, close the retainer plate onto the top of the CPU.

  4. Pivot the release lever down and into the locked position, at the side of the socket.

    The release lever must lock down the retainer plate as you close the lever.

  5. Remove the plastic cover from the new heatsink. The heatsink will have preapplied thermal grease that is protected by a plastic cover. Do not apply any more thermal grease to the heatsink.

    Caution

    Do not apply additional thermal grease to a new heatsink that comes with preapplied grease. Too much grease will ooze out and possibly go down into the socket, damaging the components.

  6. Turn the heatsink upright and install the two washers, two springs, and two mounting screws.

  7. Carefully position and align the heatsink over the CPU.

    Caution

    Avoid moving the heatsink after it has contacted the top of the CPU. Too much movement could disturb the layer of thermal grease, leading to component damage.

  8. Lower the heatsink onto the CPU, aligning the two mounting screws with their holes on the motherboard.

  9. Alternately tighten the two heatsink mounting screws one-half turn (180 degrees) at a time until each spring is compressed and the screw bottoms out on board. Hand tighten–do not force–the screws approximately 8 in/ounce.
