System-specific DDR4 server kit

This NEMIX RAM kit delivers 512GB of DDR4 3200 ECC registered memory in eight 64GB modules. It is built for Thinkmate RAX-PT rackmount servers that require registered DIMMs with error correction. The 4Rx4 organisation and CL22 timing match the platform specifications exactly.

Installation notes for registered ECC DIMMs

Registered modules must be seated firmly until the retention clips click, and the server BIOS should recognise each 64GB rank without manual voltage changes at 1.2V. Mixing these 4Rx4 sticks with different rank counts or unbuffered DIMMs will prevent the system from posting.

Suited for Thinkmate RAX-PT capacity upgrades

This kit fits administrators expanding memory in the listed Thinkmate models where 512GB is supported. Buyers who need unbuffered ECC UDIMMs, non-ECC desktop memory, or a lower total capacity should look at a different product.
