256GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit delivers 256GB of registered ECC DDR5 memory in two 128GB modules. It runs at 4800MHz with CL40 latency at 1.10V. The 4Rx4 organisation and 288-pin RDIMM form factor target the Thinkmate GPX-XS8-24S4-4GPU workstation. Modules use major OEM Samsung, Micron or Hynix chips and ship without heat spreaders.

Suits ECC workstations needing maximum capacity

Builders who require registered ECC memory with 256GB total capacity for the named Thinkmate platform will find this kit validated. Buyers who need unbuffered DIMMs, non-ECC modules, lower densities or a different pin count should look elsewhere. The kit is engineered for DDR5 4800 registered server motherboards only.

4Rx4 registered ECC at DDR5 4800

The decisive specification is the 4Rx4 registered ECC organisation running at DDR5 4800 (PC5-38400). This rank and buffer configuration must match the workstation memory controller qualification list. If the platform requires a different rank structure, voltage or buffer type, the modules will not operate correctly.

Questions about this item

Should I pick the 256GB kit or look for a different capacity?

This kit provides 256GB total using two 128GB modules, which is the only capacity offered for this part number.

What does the DDR5 4800 rating mean once the memory is installed?

The modules run at 4800 MT/s with CL40 latency at 1.1V, delivering PC5-38400 bandwidth when the workstation's memory controller is set to that speed.

How does the 288-pin RDIMM interface limit what I can do?

The 288-pin registered DDR5 form factor fits only motherboards with DDR5 RDIMM slots; it will not fit UDIMM or SODIMM sockets and requires a platform that supports registered ECC memory.
