  • On-die ECC and thermal sensor protect data integrity from 0 to 85 °C

Workstation DDR5 ECC Kit

This 256 GB kit contains eight 32 GB registered DDR5 modules rated at 4800 MT/s with CL40 timing and on-die ECC. It targets AMD Threadripper WRX90 workstation motherboards and uses AMD EXPO profiles for validated overclocking.

Motherboard Slot And Voltage Check

Verify the board has eight 288-pin DDR5 RDIMM slots and supports 1.25 V registered memory. The kit is not compatible with desktop or laptop platforms and requires a WRX90 chipset motherboard to function.

Patented Micro-Heatsink Cooling

Exclusive RCD and PMIC micro-heatsinks cover the register and power-management chips to improve thermal headroom. A built-in temperature sensor monitors module health from 0 to 85 °C and helps maintain long-term reliability.

商品問答

Does the 256 GB kit include only the eight 32 GB DDR5 RDIMMs, or are cables and tools also supplied?

The package contains the eight 32 GB modules; no cables, tools or extra accessories are included.

Should I pick the CL36 or CL40 version for an AMD Threadripper WRX90 build?

The module runs at CL40 with timings 40-39-39-77; that is the latency profile this kit provides.

Will the 4800 MT/s speed stay active once the EXPO profile is enabled on a WRX90 board?

Yes, the AMD EXPO profile sets the kit to 4800 MT/s at 1.25 V with CL40 timings.
