Target platform and capacity

This 256GB kit (2 x 128GB) is built for the ASUS WRX80 Creator R2.0 motherboard. It supplies registered ECC DDR4 memory for workstations that need error correction and high module density in a two-slot configuration.

Registered DDR4 3200 limits

The modules run at DDR4 3200 (PC4 25600) with CL22 latency at 1.2V. Registered buffering and 4Rx4 organisation are required by the platform; unbuffered or non-ECC DIMMs will not function in this system.

Physical build and daily implications

Chips from major OEM suppliers (Samsung, Micron, Hynix) are mounted on bare 288-pin RDIMM PCBs without heat spreaders. The low-profile design fits dense server chassis, but airflow across the modules must be provided by the system fans.

Questions about this item

Should I choose the 256 GB kit or look for a different capacity for my WRX80 Creator R2.0?

This kit provides 256 GB using two 128 GB modules, matching the board's eight-slot layout and letting you reach the platform's maximum supported memory.

What does the 3200 MHz rating deliver once the modules are installed in the WRX80 Creator R2.0?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency, giving the workstation its rated bandwidth for multi-threaded workloads and large datasets.

Does the 288-pin RDIMM interface limit how many modules I can populate on this motherboard?

The 288-pin ECC registered RDIMM form factor fits all eight DDR4 slots on the WRX80 Creator R2.0, so you can fully populate the board without interface restrictions.
