192GB DDR5-5600 ECC UDIMM kit

This 192GB kit contains four 48GB DDR5-5600 ECC UDIMM modules built for servers and workstations that require error-correcting unbuffered memory. It is not compatible with desktop or laptop computers.

Unbuffered dual-rank modules without heat spreaders

Each 288-pin DIMM uses Major Brand DRAM IC chips in a 2Rx8 configuration and runs at the standard 1.1V. The unbuffered design connects directly to the memory controller, while the lack of heat spreaders keeps the modules low-profile for dense server chassis.

DDR5-5600 speed with CAS 40 latency

The PC5-44800 rating delivers 5600 MT/s bandwidth at CL40 timing. ECC operation adds parity overhead that slightly reduces usable bandwidth compared to non-ECC modules, and the quad-channel kit requires a platform that supports four simultaneous channels to reach full throughput.

Questions about this item

What bandwidth does the PC5-44800 DDR5 interface deliver?

The kit runs at DDR5 5600 (PC5-44800), providing up to 44800 MT/s per module for server and workstation workloads.

Will these 288-pin ECC UDIMM modules fit my server board?

Each 48 GB module uses the standard 288-pin DDR5 DIMM form factor and requires a DDR5 server or workstation motherboard that supports ECC unbuffered memory.

How do I install the quad-channel kit correctly?

Populate all four slots in the motherboard's recommended channel order — usually slot 1 of each channel first — and verify the BIOS detects 192 GB at 5600 MT/s.
