Exact-Match Server Upgrade

This 64 GB DDR5-6400 (PC5-51200) registered ECC RDIMM is built to the precise 2Rx4 rank, 1.10 V voltage and CL52 timing the target platform expects. It installs as a direct replacement so the memory controller recognises full capacity at rated speed without manual tuning.

Build Integration

The 288-pin registered form factor matches the motherboard's DIMM slots and population rules; no UDIMM or SODIMM will fit. Registered buffering offloads the memory controller, allowing every slot to run fully populated, while on-die ECC corrects single-bit errors before they reach the operating system.

Sustained Operation

Registered architecture and ECC maintain stability when all channels are loaded continuously, preventing the silent corruption that can accumulate during long compute runs. Major-brand Samsung, Micron or Hynix DRAM chips deliver consistent throughput at the specified 1.10 V across extended duty cycles.

Questions about this item

Will the 6400 MT/s speed hold under sustained server loads without throttling?

The module runs at 6400 MT/s with CL52 timings at the standard 1.10 V DDR5 voltage, and the registered design keeps every slot stable at that rate when fully populated.

How much heat and power does a 64 GB registered DIMM add in a 24/7 rack?

At 1.10 V with no heat spreader, the RDIMM draws minimal power and relies on normal chassis airflow; the registered buffer reduces electrical load on the memory controller.

Which motherboard slot and population rules must I check before installing this 2Rx4 kit?

It is a 288-pin DDR5 RDIMM validated for the ASRock Rack GENOA2D16NQM3-2Q; consult that board's manual for approved DIMM order and maximum capacity per channel.
