Capacity 256GB 4X64GB

  • 256 GB capacity across four 64 GB modules for high-density server workloads
  • DDR5 5600 speed rated at PC5-44800 for fast data throughput
  • ECC registered RDIMM design detects and corrects errors to protect data integrity
  • Low 1.1 V operating voltage reduces power draw in dense configurations
  • Validated for ASRock WRX90 WS EVO motherboard to ensure reliable compatibility

Capacity and configuration

This kit supplies 256GB of DDR5 memory across four 64GB modules. It is built for servers and workstations that require registered ECC RDIMMs for data integrity and high-density operation.

Registered ECC limits

The modules operate at DDR5 5600 with a CAS latency of CL46 and 1.1V. Registered signalling and ECC add command-cycle overhead, so raw bandwidth is lower than unbuffered equivalents at the same data rate.

Motherboard-specific validation

The kit is tested for the ASRock WRX90 WS EVO motherboard using part number MR44800-924K4. Systems with different memory controllers or slot populations may not boot or may run at reduced speeds.

Questions about this item

Should I pick the 4×64 GB kit or a different capacity?

This kit provides 256 GB total across four 64 GB modules, designed as a matched set for the ASRock WRX90 WS EVO motherboard.

What does the DDR5 5600 CL46 rating deliver in my server?

It runs at 5600 MT/s with CAS latency 46 at 1.10 V, giving registered ECC bandwidth of PC5-44800 for stable throughput under load.

How does the 288-pin RDIMM interface limit what I can install?

The 288-pin DDR5 RDIMM form factor fits only DDR5 registered DIMM slots; it cannot be used in UDIMM or SO-DIMM sockets.
