256GB DDR5 4800 ECC RDIMM Kit

This NEMIX RAM kit supplies 256GB across two 128GB modules running at DDR5 4800 with CL40 latency. Each stick is a registered 4Rx4 RDIMM operating at 1.10V and includes on-die ECC for data integrity. The modules are validated for ThinkMate Supermicro SuperServer 111C-NR, 121C-TN2R and 121C-TN10 platforms.

Suited for registered DDR5 servers needing high

IT teams expanding memory in the listed ThinkMate SuperServer models will find this kit drops straight into the qualified slots. Builders targeting consumer motherboards, laptops or workstations that accept only unbuffered UDIMMs cannot use these registered modules. Systems limited to lower maximum densities per slot should also look elsewhere.

Registered 4Rx4 organisation with ECC

The 4Rx4 rank structure and registered buffer are the decisive specifications; they determine whether the memory controller can address the full 256GB and maintain error correction under load. Verify that your ThinkMate server documentation explicitly supports 4Rx4 RDIMMs at DDR5 4800 before purchasing.

Questions about this item

Should I choose the 256GB (2x128GB) kit or look for a different capacity?

The kit provides 256GB total using two 128GB DDR5 4800 CL40 ECC RDIMM modules. Confirm your THINKMATE SuperServer 111C-NR or 121C-TN2R/TN10 supports 128GB per slot and 4Rx4 registered DIMMs before ordering.

What does the DDR5 4800 PC5-38400 rating mean once installed?

The modules run at 4800MT/s with CL40 latency at 1.1V. As registered ECC RDIMMs they add one cycle of buffering, which the memory controller manages for signal integrity in multi-DIMM server configurations.

How does the 288-pin DDR5 RDIMM interface limit performance?

The 288-pin DDR5 RDIMM form factor carries the 4800MT/s data rate and 1.1V supply. Bandwidth and timing are capped by the DDR5 4800 JEDEC specification and the server memory controller's supported speeds.
