32GB DDR4 3200 ECC RDIMM Kit

This 32GB kit contains two 16GB DDR4 3200 registered DIMMs built for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard. ECC and registered signalling protect data integrity in server and workstation workloads. The modules run at 1.2V with CL22 latency.

Registered ECC with 2Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM format combined with a 2Rx8 rank structure. Only motherboards that accept DDR4 288-pin registered ECC modules at 3200 MT/s can use this kit. Desktop boards without registered support will not post.

Sustained load stability from factory stress testing

Every module is stress tested under load before shipment to verify stability during continuous operation. The 1.2V operating voltage and absence of a heat spreader keep thermals predictable in densely populated server chassis. ECC correction maintains data accuracy over long compute runs.

Questions about this item

What does the DDR4 3200 speed rating mean once these modules are installed in the ASUS Pro WS WRX80E-SAGE SE WiFi?

The kit runs at 3200 MT/s with CL22 latency, delivering 25600 MB/s peak bandwidth per module when the motherboard enables the rated profile.

How does the 288-pin RDIMM interface and registered design affect what the system can use?

The 288-pin DDR4 RDIMM form factor with registered buffering and ECC requires a server-class memory controller; it will not work in standard desktop boards that only accept unbuffered UDIMMs.

What physical clearance and slot population does the 2Rx8 dual-rank kit need on the WRX80E-SAGE SE WiFi?

Each 16 GB module is a standard-height 288-pin RDIMM with no heat spreader; the two sticks occupy two DDR4 slots and fit in the motherboard's eight-channel layout following the manual's population order.
