64GB DDR5-6400 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5-6400 Registered ECC RDIMMs rated at CL52 and 1.10V. It is built for servers and workstations that require registered memory with error correction, specifically validated for the ASRock Rack TURIN2D16-2T/ROT motherboard.

Check motherboard manual and population rules

Verify the motherboard manual for approved DIMM population order, maximum capacity per slot, and supported speeds before ordering. The board must accept 288-pin DDR5 RDIMMs with 1Rx4 organisation and registered ECC; UDIMMs or SODIMMs will not fit or function.

Registered ECC design for full-slot stability

The registered architecture buffers address and command signals so the memory controller can drive every populated slot at rated speed. ECC corrects single-bit errors on the fly, preventing silent data corruption. The kit frees you from mixing ranks or voltages because both modules match the board's exact specification.

Questions about this item

Does the kit include both 32 GB modules or must I buy a second stick separately?

The package contains two 32 GB DDR5 RDIMMs for a total of 64 GB, so nothing else is needed for this upgrade.

Should I choose the 64 GB 2x32 GB CL52 kit or a different capacity for the ASRock Rack TURIN2D16-2T/ROT?

This exact 64 GB (2x32 GB) DDR5-6400 CL52 1Rx4 registered ECC kit is validated for that motherboard; other capacities or timings are not confirmed.

Will the rated DDR5-6400 speed actually run at 6400 MT/s once installed in the server?

Yes, the modules are spec-matched to the board's memory controller, so they operate at the full 6400 MT/s with CL52 latency at 1.1 V.
