64GB DDR5 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5 modules rated at 4800MHz with CL40 latency. Each stick is a 1Rx8 registered DIMM operating at 1.1V with ECC error correction. The modules use 288-pin DDR5 RDIMM form factor and are validated for Thinkmate GPX-XS8-24S4-4GPU workstation compatibility.

Suited for registered-memory servers

This memory targets administrators upgrading Thinkmate workstations that require registered ECC DDR5. It is not for desktop PCs or consumer motherboards that accept only unbuffered non-ECC modules. Buyers needing higher capacities per slot or different speeds should verify their platform's qualified vendor list before ordering.

Check motherboard DDR5 RDIMM support

Confirm your workstation supports 288-pin DDR5 RDIMM modules at 4800MHz with 1.1V operation. Verify the system accepts 1Rx8 registered ECC configuration and has four available slots for this 4-module kit. Consult the hardware manual for exact population rules and maximum supported capacity per channel.

Questions about this item

Does the THINKMATE GPX-XS8-24S4-4GPU workstation need a DDR5-capable motherboard to use this 4800 MHz ECC RDIMM kit?

Yes, the modules are 288-pin DDR5 RDIMMs that only fit and function in DDR5 motherboard slots.

Can I populate the remaining DIMM slots with older DDR5 4800 MHz ECC RDIMMs of the same speed and rank?

Mixing modules of identical speed, voltage, rank and ECC type is generally supported, but the system will run at the lowest common timing.

How can I verify the kit is running at 4800 MHz with CL40 timings after installation?

Check the memory speed and latency in the BIOS setup or use a tool such as CPU-Z to confirm DDR5-4800 and CL40 operation.
