256GB DDR5 5600 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5 5600 registered ECC modules built for servers and workstations. The dual-rank 2Rx8 organisation and CL46 latency at 1.10V suit memory-intensive workloads such as virtualisation, databases and scientific computing. Error-correcting code protects data integrity in always-on environments.

Verify DDR5 RDIMM support and channel rules

Confirm that your platform accepts DDR5 registered ECC DIMMs; this kit will not work in desktop or laptop systems. Check the motherboard manual for supported speeds, maximum capacity per channel and population order before ordering. Eight modules fill multiple channels, so follow the vendor's seating guide to enable full bandwidth.

288-pin modules without heat spreaders

Each module uses a standard 288-pin DDR5 DIMM PCB with major-brand chips and no heat spreader, leaving a low profile for dense server chassis. The 1.1V operating voltage matches the DDR5 baseline, reducing power draw in fully populated systems. Registered buffering lightens the electrical load on the memory controller when all eight slots are occupied.

Questions about this item

Does the kit include eight 32 GB DDR5 5600 ECC RDIMM modules or do I need to buy additional sticks?

The kit contains eight 32 GB DDR5 5600 ECC RDIMM modules for a total of 256 GB, so no extra sticks are required.

Should I choose the 256 GB kit (8 x 32 GB) or a different capacity for my DDR5 server?

Choose the 256 GB kit if your server supports eight 2Rx8 DDR5 5600 registered DIMMs and you need maximum capacity per channel; otherwise select a smaller kit that matches your slot count.

What does the DDR5 5600 (PC5-44800) speed rating mean once the modules are installed in a compatible server?

The modules will run at 5600 MT/s with CL46 latency at the standard 1.10 V DDR5 voltage, delivering the rated bandwidth when the platform enables that speed.
