5. Gently press the CPU socket lever
down until it locks in the plastic tab.
Repeat these steps to install additional
CPUs into the other three sockets.
Installing the Heatsink Retention Modules
Four heatsink retention modules (BKT-0005) and eight screws are included in the
retail box. Once installed, these are used to help attach the heatsinks to the CPUs.
To install, position the module so that the CPU backplate standoffs insert through the
holes on the heatsink retention module and the four feet on the module contact the
serverboard. Secure the retention module to the backplate with two of the screws
provided. See Figure 5-1. Repeat for the second CPU socket.
Note: BKT-0005 is included for use with non-proprietary heatsinks only. When
installing SNK-P0012, only BKT-0004 (the CPU backplate) is needed. The BKT-
0005 retention module was designed to provide compatibility with clip-and-cam type
heatsinks from third parties.
Installing the Heatsinks
To install the heatsink (SNK-P0012, optional), do not apply any thermal compound
to the heatsink or CPU die - the proper amount has already been applied. Place
the heatsink directly on the CPU so that the two mounting holes are aligned with
those on the CPU backplate. Make sure the heatsink sits completely fl at on the
CPU - if not completely fl at, the space between the two will degrade the heat
dissipation function of the heatsink, which may cause the processor to overheat.
Screw in the two screws until just snug (do not fully tighten), then fi nish by fully
tightening both screws.
