NEMIX RAM
512 GB of DDR5 ECC registered memory in sixteen 32 GB modules running at 4800 MHz CL40 for ThinkMate SuperServer 741P-TR and 741P-TRT
This NEMIX RAM kit provides 512 GB of DDR5 ECC registered memory across sixteen 32 GB modules. It is built for THINKMATE SuperServer 741P-TR and 741P-TRT tower platforms that require registered RDIMM modules. The kit delivers PC5-38400 speed at CL40 latency with a 1.10 V operating voltage.
This configuration suits administrators expanding memory capacity in the named THINKMATE SuperServer models where 1Rx4 registered DIMMs are qualified. It is not for systems that accept only unbuffered UDIMM modules, platforms that cannot address 512 GB total capacity, or builds that need a different module count to match their memory-channel topology.
The decisive specification is the sixteen-piece 1Rx4 registered DIMM arrangement, which must match the server's qualified memory population rules. Each module uses a 288-pin DDR5 interface at 4800 MT/s with ECC and operates at 1.10 V. Verify the platform's supported rank-per-channel limits and maximum DIMM count before ordering.

The kit contains 16 modules of 32 GB each for a total of 512 GB. The server must provide at least 16 DDR5 RDIMM slots to install the full set.
Each module is rated DDR5 4800 (PC5-38400) CL40 at 1.10 V. The platform memory controller and BIOS determine the final speed when fully populated.
Enter the BIOS or UEFI and check the memory information screen for 512 GB total, DDR5 4800 speed, and ECC enabled status.
