64 GB DDR4 2400 Load-Reduced ECC Module

This SK hynix server memory module delivers 64 GB of DDR4 capacity in a single 288-pin DIMM. It operates at 2400 MT/s with a 1.20 V supply and includes on-die error-correction code. The load-reduced design reduces electrical load on the memory controller, making it suitable for high-density enterprise platforms.

Suited for servers needing maximum capacity per slot

The 4Rx4 organisation and load-reduced buffering target systems that populate every DIMM slot with large modules. Workstations or desktops that use unbuffered non-ECC memory cannot accept this module. Buyers who need standard registered ECC instead of load-reduced should verify their platform requirements before ordering.

The load-reduced buffer type decides compatibility

Only motherboards and processors qualified for DDR4 load-reduced DIMMs can use this part. Standard registered or unbuffered slots will not support the reduced electrical loading scheme. Confirm the platform memory-qualification list specifies load-reduced support for 64 GB 4Rx4 modules at 2400 MT/s.

Questions about this item

How often should the 288-pin DDR4 Load Reduced ECC module be inspected or replaced in a server running continuously?

DDR4 Load Reduced ECC modules have no scheduled replacement interval; they are solid-state components rated for continuous operation. Replace only if the system reports correctable or uncorrectable memory errors during POST or in the OS event logs.

What limits sustained throughput on this 64 GB DDR4-2400 PC4-19200 module during all-day workloads?

The 2400 MT/s data rate and PC4-19200 bandwidth ceiling are the first limits reached under sustained load; the four-rank 4Rx4 organisation adds minor command-bus turnaround latency but does not lower peak throughput.

How much power and heat does the 1.20 V 64 GB DDR4 Load Reduced module add when the server runs 24/7?

At 1.20 V the module draws roughly 5–7 W typical; Load Reduced buffering reduces electrical loading on the memory bus, so heat output stays low enough for standard server airflow without extra cooling.
