Capacity and fit

This NEMIX RAM kit delivers 768GB through six 128GB DDR4 3200 registered DIMMs built for ThinkMate HDX servers. The modules run at 1.2V with CL22 latency and a 4Rx4 organisation. Each stick is a 288-pin RDIMM with ECC and no heat spreader.

Who this suits and who should look elsewhere

IT teams running memory-intensive workloads on the listed ThinkMate HDX-XN24 or HDX-XN12 models can populate all twelve slots with two of these kits. Buyers who need a different capacity, a different speed grade, or unbuffered UDIMMs for a workstation board should look elsewhere. Systems that only accept single-rank or dual-rank modules will not support these 4Rx4 parts.

Deciding specification

The 4Rx4 rank structure is the single detail that decides compatibility. A motherboard qualified for 4Rx4 RDIMMs at DDR4 3200 will accept the kit; a board limited to 1Rx4, 2Rx4 or 2Rx8 ranks will not. Check the server’s qualified-vendor list before ordering.

Questions about this item

How do I install the 6x128GB DDR4 3200 CL22 4Rx4 ECC RDIMM modules in my ThinkMate server and which step is commonly missed?

Power down the server, open the chassis, align each 288-pin module with the DIMM slot key notch, press firmly until the retention clips lock on both ends, then populate all six slots following the motherboard population guide; the step often missed is verifying the correct channel order for 4Rx4 registered modules in the manual.

What maintenance or replacement will the 768GB DDR4 3200 ECC RDIMM kit need over its service life?

The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; replacement is only needed if a module fails ECC error correction or the server is upgraded to a platform that does not support DDR4 3200 4Rx4 registered memory.

What is the first limit that appears when the 6x128GB DDR4 3200 CL22 4Rx4 ECC RDIMM kit runs under sustained load?

The primary limit is the CL22 latency at 3200 MT/s, which sets the minimum access delay; sustained heavy workloads will encounter this timing boundary before bandwidth or voltage constraints become limiting factors.
