512 GB DDR4 3200 CL22 ECC registered server memory kit with four 128 GB 288-pin RDIMM modules at 1.2 V for ASUS WRX80 Creator motherboards
This 512GB kit contains four 128GB DDR4 3200 registered DIMMs built for the ASUS WRX80 Creator and WRX80 Creator R2.0 motherboards. ECC and registered signalling protect data integrity in multi-threaded server workloads. The modules run at 1.2V with CL22 latency and a 4Rx4 organisation. They target administrators who need maximum capacity per slot in a validated platform.
Each stick is a 288-pin RDIMM without a heat spreader, so clearance around CPU coolers is not restricted by tall modules. The registered buffer reduces electrical load on the memory controller, allowing all eight channels of the WRX80 platform to be populated. No additional cooling hardware is required beyond standard server airflow. The kit arrives as a matched set to simplify installation.
Under continuous load the ECC logic corrects single-bit errors on the fly without halting the system. Registered buffering keeps signal quality stable across all four ranks per module during long compute runs. The 1.2V operating voltage limits power draw while the memory controller manages refresh cycles. This configuration is suited to workloads that run for hours rather than short benchmarks.

The memory controller reaches its maximum supported rank count before bandwidth or thermal limits become a concern.
Registered DDR4 modules produce no audible noise, run at standard server temperatures and draw only the 1.20 V specified for the kit.
The kit is validated for the ASUS WRX80 Creator and WRX80 Creator R2.0 motherboards.
