128 GB ECC RDIMM for ASRock WRX90

This NEMIX RAM module delivers 128 GB of DDR5 5600 registered ECC memory in a single 288-pin RDIMM. It operates at 1.1 V with a CAS latency of CL46 and uses a 4Rx4 rank configuration built from major OEM chips. The part is validated for the ASRock WRX90 WS EVO motherboard.

Who this suits and who should look elsewhere

System builders expanding an ASRock WRX90 WS EVO workstation or server with high-capacity registered ECC memory will find this module compatible. Buyers needing unbuffered UDIMM memory, non-ECC modules, or capacities other than 128 GB per slot should select a different part.

Deciding specification: 128 GB 4Rx4 DDR5 5600 RDIMM

The single specification that determines fit is the 128 GB 4Rx4 DDR5 5600 registered ECC RDIMM form factor. Only platforms that accept 288-pin DDR5 RDIMMs at this density, speed, rank and voltage can use this module.

Questions about this item

Should I choose the single 128 GB module or look for multiple smaller sticks?

This kit is a single 128 GB DDR5 RDIMM running at 5600 MT/s with CL46 latency. Using one module fills a single slot and leaves others free for future expansion.

What does the 5600 MT/s rating deliver inside the ASRock WRX90 WS EVO?

The module operates at DDR5 5600 (PC5 44800) with 1.10 V and CL46 timing, providing registered ECC bandwidth the motherboard can address at full spec.

Does the 288 pin DDR5 RDIMM interface limit capacity or speed on this board?

The 288 pin RDIMM form factor matches the WRX90 WS EVO slots exactly; the board's memory controller governs the maximum supported capacity and speed.
