8GB DDR4 3200 ECC registered DIMM for ASUS Pro WS WRX80E-SAGE SE WiFi motherboards
This 8 GB registered DIMM is built for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard. It targets system integrators and IT professionals who need validated ECC memory for stable server or workstation operation. The single-rank module installs in a standard 288-pin DDR4 slot. No heat spreader is fitted, keeping the profile low for dense configurations.
The module runs at 1.20 V with a CAS latency of CL22. Registered buffering adds one clock cycle of address-command delay, which is required by the platform chipset. Mixing registered and unbuffered DIMMs is not supported by the memory controller. Population rules for the WRX80E-SAGE SE WiFi board dictate which slots must be filled first for correct channel interleaving.
Each stick provides a single 8-bit rank, so total capacity scales with the number of populated slots. Builders who need more than 8 GB per channel must add further modules rather than using a dual-rank alternative. Systems requiring higher per-DIMM density or non-ECC memory cannot use this part.

The module is an 8GB single rank 1Rx8 DDR4 3200 ECC RDIMM; populate the board's eight DDR4 slots in matched sets to reach the desired total capacity.
It runs at 3200 MT/s with CL22 latency at 1.2V, providing registered ECC bandwidth of PC4-25600 for stable server workloads.
The 288-pin DDR4 RDIMM fits only DDR4 RDIMM slots; the registered buffer and ECC require a supporting chipset and cap operation to the module's rated 3200 MT/s.
