Target System and Capacity

This 256 GB kit contains eight 32 GB DDR5 registered DIMMs built for the Thinkmate GPX-XS8-24S4-4GPU workstation. It is intended for IT professionals who need maximum memory capacity in that specific platform.

Registered ECC Design and Daily Handling

Each module is a 288-pin DDR5 RDIMM with 2Rx8 organisation, ECC error correction and 1.10 V operation. The registered buffer adds electrical load stability for dense population, while the absence of heat spreaders keeps the modules low-profile for tight server chassis.

Pre-Installation Checks

Verify that the workstation has eight free DDR5 RDIMM slots and that the BIOS supports 256 GB total at 4800 MT/s with CL40 timing. Confirm the board accepts 2Rx8 registered modules and that the power budget allows eight sticks at 1.10 V.

Questions about this item

What does the DDR5 4800 (PC5-38400) interface mean for actual throughput?

DDR5 4800 runs at 4800 MT/s, giving a peak data rate of PC5-38400 per module; real-world throughput depends on the platform's memory controller and channel population.

Will these 288-pin RDIMMs fit the Thinkmate GPX-XS8-24S4-4GPU memory slots?

Yes, the kit is built as 288-pin DDR5 RDIMMs specifically validated for the Thinkmate GPX-XS8-24S4-4GPU workstation.

What is the correct installation sequence for the eight 32 GB modules?

Populate all eight slots following the motherboard's channel map — typically one module per channel first — and ensure each RDIMM clicks fully into the 288-pin socket.
