Exact-match DDR5-6400 ECC RDIMM

This 64GB DDR5-6400 (PC5-51200) module uses a 2Rx4 registered ECC layout at 1.10V with CL52 timing. It is built to the precise rank, voltage and timing the ASRock Rack TURIN2D24XGM/500W motherboard expects so the memory controller recognises full capacity at rated speed. The 288-pin RDIMM form factor matches the board's registered DIMM requirement and population rules. Builders needing unbuffered UDIMMs or SODIMMs cannot use this module.

Thermals noise and power draw

Operating at 1.10V without a heat spreader, the module draws minimal power and produces negligible acoustic output in normal server operation. Registered buffering reduces electrical load on the memory controller, helping keep system thermals stable across fully populated slots. ECC corrects single-bit errors on the fly, preventing silent data corruption without adding measurable latency or heat. The design suits dense rack environments where consistent low-power behaviour matters.

Sustained load behaviour

Under continuous workloads the registered architecture offloads the controller so every slot runs fully populated at full 6400 MT/s throughput. ECC protection remains active during extended operation, catching and correcting errors before they reach production data. Lifetime replacement warranty and US-based technical support back the module for long-term deployment. Verify your system manual for supported capacities and approved DIMM population order before installation.

Questions about this item

How do I install this 64GB DDR5 6400 CL52 2Rx4 ECC RDIMM in the ASRock Rack TURIN2D24XGM/500W, and what step is often missed?

Align the 288-pin module with the DDR5 slot key, press firmly until both retention clips lock, then verify the motherboard manual's required population order for 2Rx4 registered DIMMs so the memory controller initialises all 64GB at 6400 MT/s.

What maintenance or replacement will this registered ECC RDIMM need over its service life?

The module has no heat spreader and no moving parts; ECC corrects single-bit errors automatically, so only a confirmed uncorrectable error or a capacity upgrade would require replacement.

What limit appears first when this 1.1V DDR5 6400 RDIMM runs sustained workloads on the TURIN2D24XGM/500W?

The memory controller's maximum supported rank count per channel is reached before thermal or voltage limits, so population rules cap usable capacity per channel.
