128GB DDR5 ECC RDIMM kit for ASRock WRX90 WS EVO

This 128GB kit contains eight 16GB DDR5 registered DIMMs rated at 4800MHz with CL40 latency. ECC and registered buffering provide the data integrity required by workstation and server workloads. The modules are validated for the ASRock WRX90 WS EVO motherboard.

288-pin registered modules without heat spreaders

Each DIMM uses a 288-pin DDR5 RDIMM form factor and operates at 1.10V. The absence of heat spreaders keeps the profile low for dense server chassis. Major OEM chips from Samsung, Micron or Hynix are used throughout the kit.

Verify motherboard model and slot population rules

Confirm the board is the ASRock WRX90 WS EVO before ordering, as this kit is qualified for that specific model. Check the manual for the supported memory population sequence and maximum capacity per channel. Ensure the platform accepts registered ECC DDR5 RDIMMs.
