Exact-match server upgrade

This 256 GB kit delivers four 64 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. Registered ECC circuitry and 2Rx4 organisation meet the ASRock Rack TURIN2D16-2T/ROT memory controller requirements for full-capacity recognition at rated speed.

Sustained-load behaviour

Registered buffering reduces electrical load on the memory controller so all slots stay stable when fully populated during continuous workloads. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption that could otherwise cause unplanned reboots in production environments.

Build and daily implications

Modules use major OEM Samsung, Micron or Hynix components without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM form factor fits only registered DIMM slots; UDIMM or SODIMM systems cannot accept these modules. Consult the motherboard manual for approved population order before installation.

Questions about this item

How much power does the 1.1V DDR5 6400 kit draw when the server runs continuously?

Each module operates at 1.1V. Total power depends on the ASRock Rack TURIN2D16-2T/ROT memory controller load; registered buffering reduces electrical load per slot.

What motherboard slot and population rules must my ASRock Rack TURIN2D16-2T/ROT already have free for this 4x64GB kit?

The board needs four free 288-pin DDR5 RDIMM slots. Follow the manual's population order for 2Rx4 registered modules to reach 256GB at 6400 MT/s.

Will these CL52 2Rx4 registered ECC modules work alongside any older DDR5 RDIMMs I keep in the same TURIN2D16-2T/ROT?

Mixing ranks, speeds or latencies can force the controller to downclock all channels. For stable 6400 MT/s operation, populate all four slots with this matched 2Rx4 CL52 kit.
