576GB DDR5 ECC RDIMM kit for Thinkmate RAX-XS4-21S4

This registered DDR5 memory kit provides 576GB total capacity across six 96GB modules. It is built for the Thinkmate RAX-XS4-21S4 rackmount server where ECC registered DIMMs are required for data integrity and maximum density.

2Rx8 organisation with 288-pin DDR5 form factor

Each module uses a 2Rx8 layout and standard 288-pin DDR5 RDIMM connectors that slot directly into the server's memory channels. The registered buffer reduces electrical load on the memory controller, supporting stable operation in fully populated configurations without a heat spreader.

Six-module kit tested for compatibility

The package contains six matched 96GB modules pre-validated for the target platform. Rigorous stress testing under load is performed before shipment to confirm reliability in mission-critical environments, and lifetime replacement coverage is included.

Questions about this item

What speed does DDR5 4800 run at in a Thinkmate RAX-XS4-21S4 server?

The kit operates at DDR5 4800 (PC5-38400) with CL40 latency when installed in the compatible Thinkmate RAX-XS4-21S4 system.

How many 288-pin DDR5 RDIMM slots does the 576GB kit fill?

The kit contains six 96GB modules, so it occupies six 288-pin DDR5 RDIMM slots in the server.

Do I need to follow a specific slot order when installing the six 96GB RDIMMs?

Yes — consult the Thinkmate RAX-XS4-21S4 manual for the correct population sequence; installing modules in the wrong order is the most common mistake.
