Independent Loading Mechanism (ILM)
As indicated in 
, the shoulder screw, socket protrusion and ILM key features 
prevent 180 degree rotation of ILM cover assembly with respect to socket. The result is 
a specific Pin 1 orientation with respect to ILM lever.

ILM Interchangeability
ILM cover assemblies and ILM back plates built from the Intel controlled drawings are 
intended to be interchangeable. Interchangeability is defined as an ILM from Vendor A 
will demonstrate acceptable manufacturability and reliability with a socket body from 
Vendor A, B, or C. ILM cover assemblies and ILM back plates from all vendors are also 
interchangeable.
The ILMs are an integral part of the socket validation testing. ILMs from each vendor 
will be matrix tested with the socket bodies from each of the current vendors. The tests 
would include manufacturability, bake and thermal cycling.
See 
 for vendor part numbers that were tested. 
Note:
Desktop and Server ILM backplate/screws are NOT interchangeable.
Note:
ILMs that are not compliant with the Intel controlled ILM drawings can not be assured 
to be interchangeable.
