256 GB DDR5 kit for ThinkMate servers

This NEMIX RAM kit provides 256 GB of DDR5 memory across eight 32 GB registered DIMMs. It operates at 4800 MT/s with CL40 latency and 1.10 V. ECC and registered buffering protect data integrity in the ThinkMate GPX-QH12-12E4-2GPU server.

Who this suits and who it does not

The kit fits administrators expanding the ThinkMate GPX-QH12-12E4-2GPU with 288-pin DDR5 RDIMM slots. Buyers needing unbuffered UDIMMs, a different pin count, or non-ECC modules should look elsewhere.

Decisive specification

Registered ECC RDIMM with 2Rx8 organisation is the single specification that determines compatibility. Only systems designed for 288-pin DDR5 registered ECC memory can use this kit.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules into the Thinkmate server, and what step is often missed?

Power off the server, open the chassis, align each module's notch with the slot key, press firmly until both latches click, then verify all eight modules are seated before closing the case.

What maintenance or replacement will the 256GB ECC RDIMM kit need over time?

The modules have no heat spreaders and no moving parts, so no routine maintenance is required; replacement is only needed if a module fails or capacity must be increased.

What limit appears first when the 4800 CL40 2Rx8 registered memory runs sustained workloads?

The CAS latency of CL40 at 4800 MT/s sets the timing ceiling, and the 1.10 V operating voltage defines the thermal envelope under continuous load.
