64GB ECC UDIMM kit for servers

This 64GB kit contains four 16GB DDR4 2400MHz modules built with ECC error correction and an unbuffered design. It targets administrators upgrading compatible servers or workstations that require registered-free memory at PC4-19200 speed. The modules operate at a standard 1.2V and carry a CAS latency of 17 for stable operation.

288-pin dual-rank build quality

Each stick uses a 2Rx8 organisation assembled from major OEM Samsung, Micron or Hynix components on a 288-pin UDIMM PCB. The unbuffered layout means the modules plug directly into standard DDR4 slots without a register chip, simplifying installation in platforms that support ECC unbuffered memory. Gold-edge contacts resist oxidation during long service cycles.

Check DDR4 ECC unbuffered support

Before ordering, verify that your motherboard or system accepts DDR4 2400MHz ECC UDIMM modules and can populate four slots with a 2Rx8 configuration. Confirm the platform does not require registered or load-reduced DIMMs, which are electrically incompatible. Ensure the BIOS can initialise the full 64GB capacity at the rated speed and latency.

Questions about this item

What does the DDR4 2400 PC4-19200 rating mean for actual bandwidth?

Each module is rated for 2400 MT/s and PC4-19200, the industry designation for that speed grade; real-world throughput depends on the platform's memory controller.

Will these 288-pin ECC UDIMMs fit my server's DIMM slots?

The kit uses standard 288-pin DDR4 UDIMM form factor, so it fits any server or workstation board that accepts unbuffered ECC DDR4 DIMMs.

What is the correct way to install the four 16 GB sticks, and what step is often missed?

Populate the slots in the order shown in the motherboard manual — usually one per channel first — and press each DIMM down until both side clips click; the common mistake is stopping before the clips latch fully.
