WRX90 OC R-DIMM 256GB Kit

This V-color kit delivers 256GB of DDR5 registered ECC memory across eight 32GB modules. It targets AMD Threadripper PRO 7000 series workstations running WRX90 motherboards that require registered DIMMs with on-die error correction. The AMD EXPO profile sets 6800MHz at CL34-46-46-92 using 1.4V.

288-Pin RDIMM Build Integration

Each 2Rx8 module occupies a single 288-pin DDR5 slot and relies on the platform's registered buffer to maintain signal integrity across all eight channels. The SK Hynix ICs sit on a 10-layer PCB tested via automated sorting, while the patented copper-alloy micro-heatsinks on the RCD and PMIC reduce local temperatures by 30 to 40 percent versus bare modules.

Patented Micro-Heatsink Advantage

The exclusive RCD and PMIC micro-heatsinks ship pre-attached and require no extra mounting hardware or software configuration. They dissipate heat from the two hottest components on every stick, preserving stability during sustained overclocked workloads without consuming additional case clearance or fan headers.

Questions about this item

Does the 1.4 V operating voltage push thermal limits during sustained 6800 MHz workloads?

A patented micro-heatsink covers the RCD and PMIC, cutting their temperature rise by 30 to 40 percent versus bare modules, so the 1.4 V supply stays within safe thermal margins during extended high-speed runs.

How much heat and power draw should I expect when all eight modules run at 6800 MHz continuously?

The copper-alloy micro-heatsinks on the RCD and PMIC reduce their temperature rise by 30 to 40 percent, keeping the 1.4 V, 256 GB kit thermally stable during all-day 6800 MHz operation.

Which motherboard and CPU combination is required for this 8 x 32 GB kit to function?

It is built for AMD Threadripper PRO 7000 series processors on WRX90 workstation motherboards that support DDR5 OC R-DIMM with AMD EXPO profiles.
