This topic describes how to upgrade an X8450 Server Module from a two-socket CPU configuration to a four-socket CPU configuration.
For X8450 CPU and heatskink replacement procedure, see Replace CPU and Heatsink (X8450 Server Module).
Follow these steps to add CPUs and heatsinks to CPU slots 2 and 3 on the X8450 Server Module:
Follow these steps to remove the air baffle covering CPU slot 2 (or 3). The number 1 in the illustration below highlights the air baffle slot locations.
Use a No. 2 Phillips screwdriver to loosen the two captive screws on an air baffle.
Pull up the air baffle to expose the CPU socket.
Pull the CPU socket locking lever into the Open position.
Remove the CPU and heatsink from the packaging.
Orient the CPU chip with the socket so that the processor cut-outs on the bottom side of the chip match the socket notches.
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. If the processor does not drop easily into the socket, make sure the lever is in the fully-opened position
When the CPU is fully seated in the socket, push the CPU socket locking lever down to the Close position.
Install the new heatsink over the CPU socket as follows:
If protective packaging covers the thermal interface material (TIM) on the underside of the heatsink, remove the protective packaging.
Lower the heatsink over the CPU socket, aligning the 4 captive screws with the holes on the motherboard.
Finger-tighten the 4 captive screws according to the numbers (1-4) shown in the figure above.
To fully secure the heatskink on the motherboard, re-tighten each captive screw using a 9/64 Allen (hex-head) wrench in the same order as Step 6c
Repeat Steps 1 through 6d to remove the second air baffle and to install the second new CPU and heatsink.
