32GB DDR5 RDIMM for ASRock Rack W890D8-2L2T

This 32GB DDR5 registered DIMM is built for the ASRock Rack W890D8-2L2T motherboard. It targets server and workstation builds that require ECC error correction and registered signalling for stability. The single-module layout suits configurations that populate one slot at a time.

Low-voltage operation at 1.1V with CL52 latency

Running at 1.10 volts, the module draws minimal power while maintaining DDR5 6400MHz speed. CAS latency of 52 cycles is standard for registered ECC parts at this frequency. No heat spreader is fitted, so airflow across the PCB handles thermal dissipation in typical chassis layouts.

288-pin 2Rx8 layout with major OEM chips

The 288-pin form factor matches the DDR5 RDIMM slot on the target board. Dual-rank 2Rx8 organisation uses Samsung, Micron or Hynix components depending on supply. Registered buffering and ECC support data integrity for continuous workloads. Installers should verify slot population rules in the motherboard manual before adding further modules.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in the ASRock Rack W890D8-2L2T and what step is often missed?

Power off the server, open the chassis, align the module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the 6400 MHz speed and ECC are active — the step most often missed is enabling the correct memory profile in firmware.

What maintenance or replacement will this 32 GB ECC registered module need over its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts. Replace it only if diagnostics report uncorrectable ECC errors or the system fails to post with this DIMM installed.

What limit appears first when this CL52 1.1 V DDR5 RDIMM runs under sustained load?

The primary limit is the CAS latency of 52 cycles at 6400 MHz; sustained throughput is bound by that timing and the fixed 1.1 V operating voltage, not by thermal throttling.
