Unified Retention System Support
The Compute Module complies with Intel’s Unified Retention System (URS) and the Unified
Backplate Assembly. The Compute Module ships with a made-up assembly of Independent
Loading Mechanism (ILM) and Unified Backplate at each processor socket.
The URS retention transfers load to the Compute Module through the unified backplate
assembly. The URS spring, captive in the heatsink, provides the necessary compressive load
for the thermal interface material. All components of the URS heatsink solution are captive to
the heatsink and only require a Philips* screwdriver to attach to the unified backplate assembly.
See the following figure for the stacking order of the URS components.
