AMD EPYC Threadripper SP3 TR4 sTRX4 Gray CPU Carrier Frame Mount Caddy Tray

This gray CPU carrier frame holds a compatible AMD EPYC or Ryzen Threadripper processor during installation into the motherboard’s socket-loading mechanism. Molded retaining tabs secure the processor package, while guide edges slide into the socket’s rail frame to position the CPU before the metal retention assembly is closed.

Designed for matching SP3 / TR4 / sTRX4 carrier configurations, this replacement is useful when the original carrier is missing, cracked, warped, or unable to hold the CPU securely. Its open center leaves the processor’s heat spreader accessible for the appropriate heatsink or liquid-cooling assembly.

This listing supplies the gray carrier frame. Separate green, blue, and orange listings are linked below. The processor, motherboard socket, metal retention mechanism, heatsink, installation tool, and thermal compound are sold separately.

Interchangeable / Replacement Part Numbers

Carrier Markings and Color References

Gray / Grey — Supplied by This Listing: 19474 REV-T
Green: 19284 REV-T, DC-19284-REV-T, D/C 20162 REV-T
Blue: 18243 REV-T
Orange: 18502 REV-T
Additional Carrier Identification: CARRIER FRAME SP3, REV-T, REV T

19474 REV-T is the gray-carrier catalog reference. 19284 REV-T / DC-19284-REV-T identifies the related green listing, and D/C 20162 REV-T is visible on that green carrier’s product photographs.

A number preceded by D/C is a production/date-code marking, rather than a unique universal replacement part number. Matching carriers can carry different production codes.

The gray carrier can replace a green, blue, or orange carrier when the processor-retaining features, guide rails, orientation, and mechanical profile match. Color alone does not establish compatibility.

Additional SP3 Carrier Model References

WNM9C00-0NAH2-EH: SP3 processor carrier reference associated with a specific socket assembly configuration. Compare its guide and retaining features with the gray carrier before substitution.
MPK-SP3-Carrier Frame: SP3 / TR4 / TRX4 carrier model designation. Compare the complete frame profile before substitution.

These references help identify the carrier application. The gray item supplied is not guaranteed to carry these markings or originate from the same manufacturer.

Ordering from this page supplies the gray version. Match the physical carrier design and intended socket application when selecting a replacement.

⭐➕ Recommended Thermal Compound — G751

Replacing a carrier usually involves removing and reinstalling the processor and cooling assembly. Clean away the old thermal compound and renew the thermal interface according to the cooler’s instructions.

Shin-Etsu G751 Microsi High Performance CPU Thermal Grease / Thermal Paste

G751 is sold separately and is applied between the processor’s metal heat spreader and the heatsink’s contact surface.

• Follow the cooler manufacturer’s recommended application pattern and quantity.
• Ensure sufficient compound is available for the large processor contact area.
• Keep compound away from underside contacts, socket contacts, and carrier guide rails.
• Follow the cooler’s instructions if it already has a new pre-applied thermal interface.
• Use a cooler approved for the processor’s socket and thermal requirements.

✔️ Confirmed Compatibility

The following processors belong to the supported SP3, TR4, or sTRX4 package families. Carrier replacement requires matching retaining-tab and rail geometry.

⚙️ Fit Notes

Before Ordering

1. Processor Outline: Confirm the correct rectangular CPU package.
2. Retaining Tabs: Match their positions to the processor edges and locating features.
3. Guide Edges: Confirm both sides engage the socket rail frame.
4. Handling Tab: Check its position and clearance.
5. Orientation: Match the CPU, carrier, and socket alignment features.
6. Condition: Retaining features must be intact and free from cracks or distortion.

The carrier should slide into the matching rail mechanism without being forced. Stop and check alignment if it binds or will not seat fully.

Installation Overview

• Shut down the system, disconnect power, and follow static-handling precautions.
• Remove the cooling assembly using the system’s service instructions.
• Open the socket mechanism in the sequence marked on the assembly.
• Handle the CPU by its edges and avoid touching underside contact pads.
• Carefully release a damaged carrier’s retaining features without bending or prying against the processor substrate.
• Secure the CPU in the replacement carrier.
• Align both guide edges and slide the assembly fully into the socket rail frame.
• Close and secure the mechanism using the specified sequence, tool, and torque.
• Clean the cooling surfaces, renew the thermal interface as required, and reinstall the approved cooler.

Follow the motherboard or system service procedure. Do not use the socket screws to pull a misaligned carrier into place.
