512GB DDR5 4800 ECC RDIMM kit

This 16-module kit delivers 512GB of DDR5 4800 registered ECC memory for Thinkmate RAX-XS4-21S4 rackmount servers. Each 32GB module operates at 1.1V with CL40 latency and a 2Rx8 organisation. The kit targets IT teams upgrading compatible Thinkmate platforms for high-capacity workloads.

Compatibility checklist before ordering

Verify that your Thinkmate RAX-XS4-21S4 server supports DDR5 4800 registered ECC RDIMMs and can address 512GB across all 16 slots. Confirm the motherboard accepts 2Rx8 modules at 1.1V and that the BIOS revision in use recognises the full capacity. Ensure the chassis has 16 free 288-pin DDR5 slots for a complete population.

What the kit changes for your server

Populating all 16 slots with matched 32GB modules enables the maximum supported memory capacity for this platform. Registered ECC operation adds error detection and correction for data integrity under sustained load. The uniform 2Rx8 rank layout keeps signal timing consistent across the full array. No heat spreaders are included, so airflow management remains the installer's responsibility.
