768GB DDR5 5600 ECC RDIMM kit

This 12-module kit delivers 768GB of DDR5 5600 registered ECC memory for the ASRock Rack TURIND12M3-2Q/E810 motherboard. Each 64GB module operates at 1.1V with CL46 latency and a 2Rx4 organisation. The registered design adds signal buffering for stable operation in multi-socket server platforms.

Sustained load behaviour

Registered ECC modules correct single-bit errors on the fly and maintain data integrity during continuous workloads. The 1.1V operating voltage reduces power draw per gigabyte compared with earlier DDR generations. Twelve ranks spread across the memory channels help the memory controller keep bandwidth steady under prolonged compute or virtualisation tasks.

Upgrade context

The kit replaces lower-capacity DDR5 RDIMM sets or fills empty slots on the target ASRock Rack board to reach the maximum supported density. Moving from a smaller registered kit to this 768GB configuration is worthwhile when virtual machine density, in-memory databases or large dataset processing exceed the current memory ceiling.

Questions about this item

How much power does the 1.1V DDR5 5600 kit draw when the server runs continuously?

Each module operates at 1.1 volts, the standard DDR5 voltage, so total power scales with the 12 x 64 GB population and the CL46 timing at 5600 MT/s.

What motherboard slot and firmware must already be present for this 288-pin RDIMM kit to function?

The kit requires a DDR5 RDIMM slot and a BIOS that supports 2Rx4 registered ECC modules at PC5-44800 speed.

Can the 12 x 64 GB 2Rx4 registered ECC modules share channels with smaller DDR5 RDIMMs already installed?

Mixing ranks is possible only if the motherboard's memory controller and BIOS allow heterogeneous 2Rx4 populations at 5600 MT/s.
