Server Memory Kit

This 64GB kit contains two 32GB DDR4 2400 LRDIMM modules built for server platforms that require registered ECC memory. The 288-pin form factor fits standard DDR4 server slots.

Registered ECC Design

Error-correcting code and registered buffering protect data integrity and reduce electrical load on the memory controller. The 4Rx4 organisation allows higher density per module while maintaining signal stability.

Capacity and Speed Headroom

The kit delivers 64GB total at PC4 19200 transfer rates. Workloads that exceed this capacity or require faster DDR4 speeds will need additional modules or a higher-frequency kit.

Questions about this item

Will the 4Rx4 registered LRDIMM modules require any firmware updates or specific BIOS settings to maintain stability over time?

Registered LRDIMM modules with 4Rx4 organisation rely on the motherboard memory controller for training and refresh management; no module-side firmware exists, so long-term stability depends on the platform BIOS supporting DDR4 2400 registered memory.

What sustained-workload limit appears first when these 32 GB DDR4 2400 LRDIMMs run continuously in a server?

The DDR4 2400 (PC4 19200) data rate sets the maximum sustained bandwidth; under continuous load the memory controller hits this throughput ceiling before thermal or power limits on the modules themselves.

How much heat and power do two 32 GB DDR4 2400 registered LRDIMMs add when the system runs all day?

Each 288-pin DDR4 2400 registered LRDIMM draws standard DDR4 voltage and the registered buffer adds minimal overhead; total heat and power scale with the 64 GB capacity and 2400 MT/s operating speed.
