128 GB DDR5 ECC RDIMM kit

This 128 GB kit contains four 32 GB DDR5 5600 RDIMM modules rated at CL46 and 1.1 V. Registered ECC operation provides error correction for data integrity in server and workstation workloads. The modules use major OEM Samsung, Micron or Hynix chips and carry the part number MR44800-314K4.

Built for ASRock WRX90 WS EVO

Designed specifically for the ASRock WRX90 WS EVO motherboard, this kit targets builders who need validated ECC registered memory for that platform. It is not suited for systems that require unbuffered UDIMM modules, non-ECC memory or a different DDR generation.

DDR5 5600 CL46 registered ECC

The decisive specification is DDR5 5600 CL46 ECC registered RDIMM at 1.1 V; only motherboards qualified for this exact speed, latency, voltage and module type should use this kit.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the ASRock WRX90 WS EVO motherboard slots?

Yes, the kit uses the standard 288-pin DDR5 RDIMM form factor that matches the WRX90 WS EVO memory slots exactly.

Do I need to enable any BIOS setting for the registered ECC memory to initialise at 5600 MT/s?

Install all four modules in the designated channels, then verify the board trains at DDR5 5600 with ECC active; registered DIMMs require the memory controller to recognise the register before full speed is negotiated.

When should the 1Rx4 Samsung, Micron or Hynix chips be replaced under sustained server workloads?

ECC corrects single-bit errors on the fly; plan replacement only if corrected-error counters rise steadily or the system logs uncorrectable errors during stress testing.
