This LGA3647 narrow CPU socket dust cover protects the delicate contact field of an empty Socket P processor socket during motherboard storage, shipping, repair, testing, and processor replacement. It is the narrow-ILM version identified by reference H77975-005 and interchanges with the verified supplier part numbers listed below. Molded markings, suffixes, and minor cosmetic details may vary depending on available inventory, but every supplied cover will use the same LGA3647 narrow mounting geometry.
CPU Medics specializes in high-volume sourcing and fulfillment for CPU socket covers and related server components. We can fulfill orders of any size, including requirements exceeding 100,000 units.
Buy with confidence. For very large orders, production requirements, scheduled releases, or specific part-number preferences, contact us so we can coordinate availability, packaging, quantities, and delivery requirements.

H77975-004 is a superseded drawing revision that was updated to H77975-005. C-2305234 and ENG_CD_2305234_A are engineering drawing or document references rather than separate orderable cover numbers.
Please note that the following list is not exhaustive. Compatibility is determined by the motherboard’s installed LGA3647 narrow bolster/ILM—not by the LGA3647 socket name alone. Verify the elongated narrow mounting geometry, original cover number, motherboard documentation, or installed bolster before ordering.

☑️ Verified interchange across the listed supplier part numbers
☑️ Compatible with narrow fabric and narrow non-fabric bolster assemblies
☑️ Molded INSTALL and REMOVE orientation markings support proper handling
☑️ Reusable design intended to be saved and replaced whenever the processor is removed
☑️ Tool-free installation when the correct narrow bolster is present
☑️ Suitable for single-socket, dual-socket, and multi-socket server motherboards
☑️ Useful for system builders, repair facilities, recyclers, data centers, manufacturers, and spare-parts programs
☑️ Molded markings and suffixes may vary while maintaining the required narrow geometry
✓ Confirm that your motherboard uses the elongated LGA3647 narrow ILM / narrow bolster. LGA3647 square and narrow covers are physically different.
✓ This cover is not compatible with the LGA3647 square cover family, including H78206-004, AZIF0105-P002C*, and WNMEL00-81W00-EH.
✓ Do not order solely by processor model. The same processor family may appear on motherboards with different retention geometry.
✓ This cover attaches to the installed narrow bolster. It is not intended to attach directly to a completely bare socket without the proper bolster hardware.
✓ This is a removable socket dust cover—not the temporary PnP cap used while the socket is soldered to a motherboard.
✓ This item is not a processor carrier, CPU clip, bolster assembly, backplate, heatsink, or processor blank.
