WRX90 Workstation Memory Kit

This 128 GB kit contains eight 16 GB DDR5 registered DIMMs built for AMD Threadripper PRO 7000 series workstations on WRX90 motherboards. ECC protection and AMD EXPO profiles keep data integrity intact while enabling one-click overclocking. The modules use SK Hynix ICs on a 10-layer PCB and include patented RCD and PMIC micro-heatsinks for thermal control.

DDR5 6000 CL32 Registered ECC

The decisive specification is the DDR5 6000 MT/s speed at CL32 latency with 1.40 V operating voltage on registered ECC architecture. This combination determines whether the kit matches your WRX90 platform's qualified-vendor list and workload stability requirements. The 1Rx8 rank configuration and 32-39-39-102 timings complete the electrical profile.

Micro-Heatsink Cooling Solution

Bundled micro-heatsinks cover the RCD and PMIC components directly, lowering their temperatures by 30 to 40 percent compared with unshielded modules. This targeted cooling sustains the EXPO overclock during prolonged compute tasks without requiring additional airflow hardware. No extra software utilities are included beyond the standard EXPO BIOS profile.

Questions about this item

What real-world data rate does the 6000 MT/s rating deliver once the modules are installed in a WRX90 workstation?

The kit runs at DDR5 6000, which is PC5 48000, so each module transfers up to 6000 million data transfers per second when the EXPO profile is active.

How does the AMD EXPO profile affect the registered DIMM interface and what limits does it impose?

EXPO loads the 6000 MT/s CL32 32-39-39-102 timings at 1.40 V on the 288-pin RDIMM interface; the registered buffer and on-die ECC remain active, so the profile caps at the rated speed and latency.

What physical clearance is needed for the patented RCD and PMIC micro-heatsinks on these 16 GB modules?

Each 288-pin RDIMM carries a copper-alloy micro-heatsink over the RCD and PMIC; the spreader fits standard DDR5 DIMM height, so only normal slot spacing is required.
