Targeted Server Upgrade

This 512 GB kit comprises four 128 GB DDR5 registered ECC RDIMMs built for the ASRock Rack TURIN2D24XGM/500W motherboard. Each module runs at DDR5 6400 (PC5-51200) with CL52 latency at 1.10 V in a 2Rx4 organisation. The registered design matches the board's required 288-pin form factor and population rules.

Sustained Load Behaviour

Registered buffering reduces electrical load on the memory controller so all four slots operate at rated speed when fully populated. On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption during continuous workloads. The 1.10 V operating voltage keeps power draw stable across extended duty cycles.

Build And Connector Implications

Modules ship without heat spreaders, relying on chassis airflow for thermal management. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM slots. Verify the motherboard manual for approved population order and maximum supported capacity before installation.

Questions about this item

How much power does the 1.10 V 6400 MHz kit draw when the server runs continuously?

The modules operate at 1.10 V and DDR5 6400 speed; registered ECC architecture reduces electrical load on the memory controller, helping keep sustained power draw low in a fully populated 512 GB configuration.

What motherboard slot and population rules are required for this 288-pin RDIMM kit?

The kit needs a motherboard with 288-pin DDR5 RDIMM slots and must follow the board's validated population order — the ASRock Rack TURIN2D24XGM/500W is the verified platform.

Will these CL52 registered ECC modules work alongside other DDR5 RDIMMs I already own?

Mixing is only reliable when the existing DIMMs match the same 6400 MHz speed, CL52 latency, 1.10 V voltage, 2Rx4 rank and registered ECC specification; otherwise the system will down-clock or fail to boot.
