Intel LGA2011-3 Socket R3 CPU Dust Protector Cover 1-2229348-1 105275-0004

This reusable LGA2011-3 CPU socket dust cover protects the exposed 2,011-contact field of an empty Socket R3 motherboard during storage, shipping, assembly, testing, repair, and processor replacement.

The cover attaches to the motherboard’s installed loading mechanism and is designed to be saved and reinstalled whenever the processor is removed. The documented cover geometry is used with validated square and narrow LGA2011-3 loading mechanisms. Manufacturer logo, molded text, color shade, and minor cosmetic details may vary depending on available inventory.

Interchangeable / Replacement Part Numbers

Verified cover-level identifiers:

1-2229348-1, 105275-0004, CPU-LGA2011-3

Common ordering, service, and socket references:

LGA2011-3, LGA2011-v3, LGA2011-V3, LGA20113, SKT-R LGA2011-3, Socket R3

• 1-2229348-1 is the verified supplier catalog number whose official description is “ILM DUST COVER LGA2011-3.” The original catalog currently classifies this number as obsolete, but it remains a valid cross-reference for existing inventory.
• 105275-0004 is the verified ILM-cover component reference shown in both square and narrow LGA2011-3 assembly drawings.
• CPU-LGA2011-3 is the CPU Medics item number.
• The remaining identifiers are common socket, marketplace, and service references—not separate engineering designs.

No additional standalone loose-cover ordering number could be verified for the other validated socket suppliers. Their published numbers identify complete loading mechanisms rather than the removable dust cover by itself.

Related square-ILM assembly references—not cover-only part numbers:

G63449-005, PT44L11-4711, 2229339-2, AZIF0018-P001C, ITLG63449001, 105274-2000

Related narrow-ILM assembly references—not cover-only part numbers:

G43051-006, PT44L12-4711, 2229339-1, AZIF0019-P001C, ITLG43051002, 105274-1000

Related ILM and backplate kit references—not cover-only part numbers:

2-2134533-1, 105274-1200, 105274-2200, PT44A12-4711

These related numbers can help identify compatible hardware, but they represent complete loading mechanisms or kits containing additional components. They should not be treated as direct loose-cover part numbers.

✅ Confirmed Compatibility

Please note that the following list is not exhaustive. Compatibility is determined by the motherboard’s installed LGA2011-3 / Socket R3 loading mechanism—not by the system name or 2,011-contact count alone. Always verify the original cover marking, socket generation, motherboard documentation, and physical attachment geometry.

⚙️ Fit Notes

✓ Confirm that the motherboard uses LGA2011-3 / LGA2011-v3 / Socket R3 and that the original cover or loading mechanism matches the pictured attachment geometry.
✓ This cover is documented for both validated square and narrow LGA2011-3 loading mechanisms.
✓ This item is not compatible with first-generation LGA2011 / Socket R motherboards, including X79 boards and processors from the Xeon E5 v1/v2 generation. LGA2011 and LGA2011-3 have the same contact count but different mechanical keying.
✓ This item is not compatible with LGA2011-1 server platforms used by certain Xeon E7 systems.
✓ LGA2066/X299 is not included in confirmed compatibility. Although some aftermarket sellers combine LGA2011-3 and LGA2066 in one listing, a released manufacturer document confirming universal cover interchange was not found. Compare the original cover and loading mechanism before considering substitution.
✓ This cover is not compatible with LGA3647, LGA4189, LGA4677, LGA4710, LGA7529, SP3, SP5, SP6, or other socket families.
