256GB DDR5 ECC RDIMM kit for ASRock TRX50

This 256GB kit provides two 128GB DDR5 registered DIMMs built for ASRock TRX50 WS motherboards. The modules deliver 5600 MT/s bandwidth with CL46 latency and on-die ECC for data integrity. They target professionals who need maximum registered capacity in a dual-channel workstation platform.

Sustained throughput with registered 4Rx4

Each module uses a 4Rx4 layout that allows the memory controller to interleave ranks during long compute runs. Registered signalling reduces electrical load on the CPU memory controller, keeping signal integrity stable when all slots are populated. The 1.1V operating voltage limits thermal output during extended workloads.

Bare modules with standard 288-pin DDR5 keying

No heat spreader is fitted, so clearance depends only on the DIMM height defined by the 288-pin DDR5 form factor. The registered buffer and ECC logic add negligible length, ensuring compatibility with standard server and workstation chassis. Installation follows the motherboard manual slot population rules for registered memory.

Questions about this item

How much heat and power will the 1.10V 4Rx4 modules generate running all day in a server chassis?

Each module operates at 1.10V DDR5 standard voltage; the 4Rx4 organisation spreads load across four ranks per DIMM, so sustained power draw stays within typical registered DIMM limits for 5600 MT/s operation.

What motherboard slot and chipset must I already have for this 288-pin RDIMM kit to function?

You need an ASRock TRX50 WS workstation motherboard with DDR5 RDIMM slots; the kit is validated for that platform and requires registered ECC support in the chipset.

Can I mix this 256GB 5600 CL46 kit with smaller-capacity DDR5 RDIMMs already installed in the same ASRock TRX50 WS board?

The board will train all populated slots to a common speed and latency; mixing ranks or capacities is supported by the platform, but the slowest module set determines the final 5600 MT/s CL46 timing for the whole array.
