256GB DDR4 ECC UDIMM kit for servers

This NEMIX RAM kit provides 256GB of DDR4 ECC unbuffered memory across eight 32GB modules. It targets system builders and IT professionals who need large-capacity, error-correcting RAM for compatible server or workstation platforms. The modules operate at 1.2V with a CL21 latency rating.

PC4-23400 speed ceiling and unbuffered constraint

The kit runs at DDR4 2933 (PC4-23400), so the memory bus cannot exceed that data rate even if the platform supports faster DDR4 speeds. Because the modules are unbuffered UDIMMs, they must be installed in motherboards that accept unbuffered ECC memory; registered or load-reduced DIMM slots will not work with this kit.

Tool-free DIMM installation with population rules

Each 288-pin module seats in a standard DDR4 UDIMM slot without tools, but the eight-module population requires a board with at least eight slots and a CPU or chipset that supports 256GB of unbuffered ECC capacity. Mixing these 2Rx8 sticks with different ranks, speeds or voltages often prevents the system from posting, so install the full matched kit together.

Questions about this item

How do I know the 8 x 32 GB kit is the right capacity for my server?

The kit provides 256 GB total across eight 32 GB modules, so confirm your motherboard has eight free DDR4 UDIMM slots and supports that density per slot.

What does the 2933 MT/s rating actually deliver in a live system?

The modules run at DDR4 2933 (PC4-23400) with CL21 latency at 1.20 V, giving that throughput when the platform enables the matching memory controller speed.

Will the ECC UDIMM interface work with registered or load-reduced DIMM slots?

These are 288-pin unbuffered ECC UDIMMs (2Rx8); they only fit motherboards designed for unbuffered ECC DDR4 and will not work in registered or LRDIMM sockets.
