32GB DDR5 ECC RDIMM for ASRock WRX90 WS EVO

This 32GB DDR5 4800 registered DIMM is built for the ASRock WRX90 WS EVO motherboard. It targets IT professionals and system builders who need error-correcting server memory for mission-critical workloads. The module uses major OEM chips from Samsung, Micron or Hynix and runs at 1.10V. It arrives new and ready for installation in compatible workstation platforms.

DDR5 4800 registered DIMM limits

Registered DDR5 4800 modules operate at PC5-38400 data rates with a CAS latency of CL40. The 288-pin RDIMM form factor fits only DDR5 RDIMM slots that support registered signalling and ECC. Unbuffered consumer boards cannot use this memory. The single-rank 1Rx4 organisation may affect maximum population rules on some workstation platforms.

32GB single-module capacity

This kit provides one 32GB stick, giving 32GB total capacity per module installed. Buyers who need higher density per slot should verify larger RDIMM options for the WRX90 WS EVO. Systems requiring non-ECC or unbuffered memory must choose a different product type.

Questions about this item

Should I pick the 1Rx4 32 GB module or a different rank for the ASRock WRX90 WS EVO?

This kit is a single 1Rx4 32 GB registered DIMM; adding identical modules keeps the memory controller in its validated configuration.

What does the 4800 MT/s rating deliver inside the WRX90 WS EVO?

The module runs at DDR5 4800 with CL40 latency at 1.10 V, giving the bandwidth and error correction the workstation platform expects.

How does the 288-pin DDR5 RDIMM interface limit speed and capacity on this board?

The registered 288-pin DDR5 interface supports the rated 4800 MT/s and 32 GB per DIMM; total capacity depends on the motherboard slot count.
