Capacity and purpose

This 64 GB kit delivers two 32 GB DDR4 3200 registered ECC modules validated for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard. It targets workstation and server builds that require error-correcting memory for data integrity.

Registered ECC design

Each module uses a 2Rx8 organisation with a 1.20 V operating voltage and CL22 latency. The 288-pin RDIMM form factor fits the board's registered DIMM slots; the lack of a heat spreader keeps the profile low for dense configurations.

DDR4 platform limits

DDR4 3200 (PC4-25600) sets the maximum transfer rate this memory can provide on the supported platform. Registered ECC modules cannot be mixed with unbuffered non-ECC DIMMs, and the motherboard must support registered memory to boot.

Questions about this item

What does the DDR4 3200 PC4-25600 rating mean for real-world bandwidth?

The DDR4 3200 modules run at 3200 MT/s with a PC4-25600 data-rate specification.

What physical slot and clearance do the 288-pin RDIMMs need on the ASUS Pro WS WRX80E-SAGE SE WiFi?

They require standard 288-pin DDR4 RDIMM slots; the modules have no heat spreader so they fit under most CPU coolers.

What is the correct installation order for the 2Rx8 registered DIMMs on this workstation board?

Populate the recommended RDIMM slots in the sequence shown in the motherboard manual, ensuring each module clicks fully into the 288-pin socket.
