64GB DDR4 2400 ECC UDIMM Kit

This 64GB kit contains eight 8GB DDR4 2400 unbuffered ECC DIMMs built for servers and workstations. Each module runs at 1.20 volts with a CAS latency of 17 and a 2Rx8 dual-rank organisation. The 288-pin form factor fits DDR4 UDIMM slots that explicitly support ECC unbuffered memory.

Servers and workstations needing ECC UDIMM capacity

The kit suits systems that require DDR4 ECC unbuffered DIMMs and can populate eight slots. It is not for desktops, laptops or any platform that only accepts non-ECC or registered memory. Buyers who need registered DIMMs, higher speeds or a different module count should look elsewhere.

Steady throughput under sustained workloads

ECC corrects single-bit errors on the fly, preventing data corruption during long compute runs. Dual-rank 2Rx8 organisation keeps all channels populated for consistent bandwidth. Standard 1.20 volt operation maintains thermal stability when the system runs fully loaded for extended periods.

Questions about this item

Does my motherboard need to support ECC unbuffered DDR4 and have eight 288-pin slots to use this 64GB kit?

Yes, the kit contains eight 8GB DDR4 2400 ECC UDIMM modules, each a 288-pin DIMM, so the board must accept ECC unbuffered memory and provide eight compatible slots.

Will these CL17 1.2V modules run stably if I keep slower DDR4 DIMMs in the same server?

The system will operate at the speed and voltage of the slowest installed modules; mixing different CAS latencies or ranks is possible but may reduce stability, so matching all slots with this kit is recommended.

How can I confirm the full 64GB is recognised and ECC is active after installation?

Check the BIOS or UEFI memory information screen — it should show 64GB total across eight slots at 2400 MT/s with ECC enabled, and the operating system should report the same capacity without errors.
