NEMIX RAM
Eight 128 GB DDR4-3200 ECC registered DIMMs totalling 1 TB for ThinkMate servers
This 1TB memory kit contains eight 128GB registered DIMMs built for Thinkmate RAX-QN12, QN24, QT10, QN10, QT24, QS12, QS4 and E2-E3 servers. It targets administrators who need maximum registered ECC capacity in supported 288-pin DDR4 platforms.
Each module uses major OEM Samsung, Micron or Hynix chips in a 4Rx4 organisation. The registered design reduces electrical load on the memory bus, while ECC corrects single-bit errors for data integrity in continuous workloads.
The jump is worthwhile when your Thinkmate server requires 1TB of registered ECC memory and the board supports 4Rx4 modules at 3200 MT/s. It does not suit systems limited to 2Rx4 ranks, unbuffered DIMMs or DDR5-only platforms.

The modules run at 3200 MT/s with a peak transfer rate of 25600 MB/s per module; actual bandwidth depends on the server's memory controller and channel population.
Yes, each 128 GB stick uses the 288-pin DDR4 RDIMM form factor and 1.20 V signalling required by the listed Thinkmate RAX and QT platforms.
Populate all eight slots following the motherboard's channel map — typically alternating channels per CPU — and seat each RDIMM until the ejector clips click; the common mistake is leaving a slot empty in an active channel.
