X5DLR-8G2 Quick Reference
Note: Please note that special, new silver heatsin retention clips must be used with all Xeon 533MHz FSB (front side bus) 604-pin
processors. These new retention clips have "604P" clearly marked on them. Using the old clips will not keep the proper amount of pressure
applied and may cause the processor to overheat. You should not use these new retention clips with 400MHz FSB processors (even if the
CPU socket is 604-pin) as they will too tight and damage the CPU socket.
Warning!
CPU Heatsink Installation Procedures (For Supermicro SuperServer 2U Systems)
Due to the fact that adequate air flow and proper thermal control are very critical in maintaining 2U system's stability and performance,
it is imperative that the proper installation procedures listed below be followed in order to maximize system performance. This is
especially critical for 2U dual Xeon processor server solutions.
1) Only those CPU heatsinks that are provided by Supermicro should be used.
2) Apply a small amount of silicon compound on the CPU's die.
3) Place the CPU heatsink on top of the CPU.
4) Attach the heatsink clips to the heatsink retention pieces, one on each side of the heatsink as shown in the diagram at right.
5) The three tabs on each heatsink retention pieces should complete protrude though the corresponding holes on the heatsink clips
