1 TB DDR5 ECC RDIMM kit

This kit provides 1 TB of DDR5 server memory in eight 128 GB registered DIMMs. It is built for Thinkmate RAX and QT series platforms that require ECC RDIMM modules. System administrators scaling virtualisation hosts or database nodes will match the validated part number directly.

Registered DDR5 at 1.1 V with CL40

The modules run at DDR5 4800 (PC5 38400) with a CAS latency of 40 and a 1.1 V operating voltage. Registered buffering and on-die ECC reduce electrical load on the memory controller while correcting single-bit errors during sustained workloads.

Eight 288-pin 4Rx4 modules without heat spreaders

Each stick uses a 4Rx4 organisation across 288 pins and ships without a heat spreader to fit dense Thinkmate chassis. Populate all twelve slots on QE12 or QH24 boards for maximum capacity or fill half the slots on smaller QT12 models for balanced channel population.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in my ThinkMate server, and which step is most often missed?

Power down, open the chassis, align each module's notch with the slot key, press firmly until both latches click, then verify all eight 128 GB sticks are seated before closing the case; the step most often missed is confirming the latches fully engage on every module.

What maintenance or replacement will the 4Rx4 ECC registered 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 necessary if a stick fails, which ECC logging will reveal through corrected error counts.

At what limit does the CL40 4800 MHz kit first show strain under sustained heavy workloads?

The primary limit is the CL40 latency at 4800 MT/s; under continuous maximum bandwidth demand the fixed timing becomes the bottleneck before voltage or thermal constraints appear.
