64 GB DDR4 ECC RDIMM kit for servers

This 64 GB kit contains eight 8 GB DDR4 2666 MHz registered DIMMs with ECC and a CAS latency of 19. It is built for servers and workstations that require registered memory and single-rank x8 organisation. The modules operate at the standard 1.2 V DDR4 voltage.

Suited for DDR4 registered memory platforms only

Buyers with desktop or laptop systems cannot use these modules because they require unbuffered non-ECC memory. Systems that do not support registered DIMMs or ECC functionality should look elsewhere. The kit is intended for compatible server and workstation motherboards that explicitly list DDR4 RDIMM support.

Straightforward DIMM installation

Each 288-pin module seats in a standard DDR4 DIMM slot following the motherboard manual for channel population order. The most common issue is attempting installation in a consumer board that rejects registered memory, resulting in a no-post condition. Verifying the system’s qualified vendor list before purchase avoids this problem.

Spurningar um þessa vöru

Does my server or workstation need DDR4 288-pin RDIMM slots to use this 8-module kit?

Yes, this 64 GB kit uses DDR4 2666 MHz registered DIMMs with 288 pins, so the system must support DDR4 RDIMM memory.

Can I mix these 1Rx8 CL19 modules with existing DDR4 2666 registered DIMMs of a different rank or latency?

Mixing is possible if the platform supports mixed ranks and latencies, but the system will run all modules at the slowest common speed and timings.

How can I confirm the kit is running at DDR4 2666 with ECC active after installation?

Check the BIOS or UEFI memory information screen for 2666 MT/s speed, CL19 timings, 1.2 V voltage and ECC status showing enabled.
