128 GB DDR4 ECC RDIMM kit for servers

This 128 GB kit contains two 64 GB DDR4 3200 registered DIMMs with ECC and a dual-rank x4 organisation. It runs at 1.20 V with CL22 latency and uses a 288-pin form factor designed for server and workstation platforms only. The modules are not compatible with desktop or laptop systems.

Suited for memory-intensive server workloads

Administrators expanding virtualisation hosts, database nodes or compute clusters will benefit from the registered ECC design and high per-module density. Builders targeting consumer motherboards, laptops or any platform lacking registered DDR4 support should look elsewhere because the modules will not function in those systems.

Sustained operation at rated speed and voltage

Under continuous load the kit maintains DDR4 3200 throughput at 1.20 V while ECC corrects single-bit errors and registered buffering reduces electrical load on the memory controller. Dual-rank x4 organisation helps keep bandwidth stable during prolonged multi-threaded tasks without exceeding the specified CL22 timing.

Questions sur cet article

Do I need a motherboard that supports DDR4 ECC Registered DIMMs with 288 pins to use this kit?

Yes. The kit contains two 64 GB DDR4 3200 ECC RDIMM modules with 288 pins, 2Rx4 organisation and 1.2 V operation, so the board must accept registered ECC DDR4 DIMMs.

Can I add these 2Rx4 modules to a server that already has 1Rx4 DDR4 RDIMMs installed?

Mixing dual-rank 2Rx4 and single-rank 1Rx4 RDIMMs is possible on many server platforms, but the memory controller will treat each rank independently; check the system manual for supported rank combinations and maximum ranks per channel.

How can I confirm the kit is running at DDR4 3200 with CL22 after installation?

Enter the system BIOS or use an OS utility such as dmidecode or CPU-Z; both modules should report 3200 MT/s, CAS latency 22, 1.20 V and ECC registered operation.
