256GB DDR4 ECC RDIMM Kit

This 256GB kit contains eight 32GB DDR4 3200 MHz registered DIMMs with ECC and a single-rank x4 organisation. It is built for servers and workstations that require registered memory and error correction.

Compatibility Check Required

Verify that your system supports DDR4 288-pin registered ECC modules at 3200 MHz with a 1Rx4 rank configuration. Desktop and laptop platforms cannot use registered DIMMs. Consult the motherboard or system manual for qualified memory lists and population rules.

Suits Multi-Socket Servers

Ideal for administrators expanding memory in compatible multi-socket servers or high-density workstations. Not for desktop PCs, laptops or any system that accepts only unbuffered non-ECC memory. Buyers needing lower capacities or consumer-form-factor modules should consider other options.

Questions about this item

Does the 256GB kit include eight 32GB modules or do I need to buy them separately?

The kit contains eight 32GB modules, providing a total of 256GB in a single package.

Should I choose the 1Rx4 single-rank version or a dual-rank alternative for my server?

This kit uses 1Rx4 single-rank x4 organisation, which is the configuration specified for compatible DDR4 servers and workstations.

Will the 3200 MHz speed run at that rate once installed in my system?

The modules are rated at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V; actual operating speed depends on the server's memory controller and BIOS configuration.
