256GB DDR5 ECC RDIMM kit for ASRock TRX50

This 256GB kit contains four 64GB DDR5 5600 registered DIMMs built for the ASRock TRX50 WS workstation motherboard. ECC and registered buffering protect data integrity in professional workloads. The modules operate at 1.1V with CL46 latency. They are intended for IT professionals and workstation builders who need validated, high-capacity server memory.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller during continuous operation, helping maintain signal quality across all four modules. ECC corrects single-bit errors in real time, preventing silent data corruption during long compute runs. The 2Rx4 organisation spreads accesses across ranks, supporting steady throughput in memory-intensive server applications. Modules are stress-tested under load before shipment.

Thermals, noise and power at 1.1V

Operating at 1.1V keeps power draw low for a 256GB configuration, reducing heat output inside dense chassis. No heat spreaders are fitted, so airflow across the bare PCBs manages temperatures directly. Silent operation is inherent with no moving parts. The low voltage also eases demand on the platform power delivery during extended sessions.

Questions about this item

How much power does the 1.1V kit draw under sustained server workloads?

Each 64 GB module runs at 1.1 V, so the four-stick kit operates at the standard DDR5 RDIMM voltage without elevated power draw.

Does the ASRock TRX50 WS motherboard need a specific BIOS version or CPU to recognise the 256 GB kit?

The kit is validated for the ASRock TRX50 WS workstation motherboard; compatibility depends on that platform's memory controller and BIOS support.

Can the 288-pin DDR5 RDIMMs be mixed with older registered DIMMs already installed in the same system?

All four modules are 288-pin DDR5 RDIMMs with 2Rx4 organisation; mixing different DDR generations or unbuffered DIMMs is not supported by the platform.
