WRX90 OC R-DIMM 512GB kit

This 512GB kit contains eight 64GB DDR5 registered DIMMs built for AMD Threadripper WRX90 workstation motherboards. Each module runs at 5600MHz with CL36 timings and 1.25V. ECC and registered buffering protect data integrity in professional workloads. The AMD EXPO profile enables one-click overclocking on supported platforms.

Sustained load behaviour

Hynix ICs on a 10-layer PCB are validated through automated sorting and rigorous testing. Patented micro-heatsinks on the RCD and PMIC lower component temperatures by 30 to 40 percent compared with bare modules. This cooling helps maintain the 5600MHz CL36 36-38-38-80 timing under continuous workstation loads. ECC corrects single-bit errors without halting the system.

Installation notes

The 288-pin RDIMMs install in standard DDR5 slots on WRX90 boards; the EXPO profile loads automatically in BIOS when enabled. All eight modules must be populated for the rated 512GB capacity. Builders who need fewer than eight modules or a different capacity should choose another kit. Compatibility is limited to AMD Threadripper PRO 7000 series on WRX90 chipsets.

Questions about this item

How much heat does the patented micro-heatsink on the RCD and PMIC actually remove when the kit runs at 5600 CL36 all day?

The copper-alloy micro-heatsink cuts RCD and PMIC temperatures by 30-40 % compared with bare modules, keeping the 1.25 V DDR5 OC R-DIMM stable during sustained workloads.

Which motherboard platform must I already have for this 8×64 GB kit to function?

An AMD Threadripper PRO 7000-series CPU on a WRX90 workstation motherboard with 288-pin DDR5 slots is required; the kit is validated only for that platform.

Can I mix these 2Rx4 Hynix IC modules with other DDR5 RDIMMs I already own?

Mixing ranks, IC vendors or EXPO profiles is not recommended; for guaranteed 5600 CL36 operation the full 512 GB kit should populate all channels identically.
