NEMIX RAM
Six 64 GB DDR5 ECC registered DIMMs deliver 384 GB at 4800 MT/s with CL40 latency for ThinkMate tower servers
This kit provides 384 GB of DDR5 4800 registered ECC memory across six 64 GB modules. It is built for ThinkMate TWX-QS8-14E4 and TWX-QS8-24E4 tower servers that require 288-pin RDIMM modules with CL40 timing and 1.10 V operation.
The modules are validated for the listed ThinkMate tower models and carry ECC and registered buffering for data integrity. Builders working with other motherboards, consumer platforms or systems that need unbuffered DIMMs should look elsewhere because this kit is system-specific and will not fit.
Install by powering down, opening the chassis and seating each 288-pin module into the correct slots per the server manual. Common issues include mixing ranks or speeds across channels and failing to enable ECC in the BIOS, which can prevent the system from posting.

This kit contains six 64GB DDR5 4800 CL40 registered DIMMs. Your ThinkMate tower server must provide six available 288-pin DDR5 RDIMM slots to install the full 384GB capacity.
All modules in this kit are DDR5 4800 (PC5-38400) at 1.10V with CL40 latency. Mixing with slower DDR5 DIMMs will force the memory controller to run every module at the lowest common speed and voltage.
Check the system BIOS or UEFI memory information screen; it should report 384GB total across six 64GB DDR5 4800 registered DIMMs with ECC enabled.
