192GB DDR5 4800 ECC RDIMM kit for ThinkMate

This 12-module kit provides 192GB of registered DDR5 4800 memory built for the ThinkMate GPX-XH8-22S4-8GPU GPU-optimised server. Each 16GB module uses a 1Rx8 layout and operates at 1.10V with CL40 latency. ECC and registered buffering protect data integrity in mission-critical workloads.

DDR5 4800 registered ECC limits for server platforms

The DDR5 4800 standard (PC5-38400) sets the maximum JEDEC speed this kit will reach on the target platform; overclocking is not supported on registered server DIMMs. Registered buffering adds one clock cycle of latency versus unbuffered modules, a trade-off required for high-capacity stability. Mixed-rank or mixed-voltage populations can prevent the system from posting.

Installing twelve 288-pin RDIMMs in a GPU server

Twelve 288-pin RDIMMs must fill the correct slots in the order specified by the ThinkMate manual; an incorrect sequence is the most common cause of a no-post condition. GPU-optimised chassis often route large graphics cards over DIMM slots, so verify physical clearance before seating every module. Handle modules by the edges to avoid contaminating the gold contacts.

Questions about this item

Should I choose the 12x16GB kit or a different capacity for my ThinkMate GPX-XH8-22S4-8GPU?

The 192GB kit provides twelve 16GB modules to fill all slots on this server platform.

What does the 4800 speed rating deliver once installed in the ThinkMate GPX-XH8-22S4-8GPU?

DDR5 4800 runs at 4800 MT/s with CL40 latency, giving the server its rated memory bandwidth for GPU-optimised workloads.

How does the 288-pin DDR5 RDIMM interface limit performance in this server?

The registered DDR5 RDIMM interface caps operation at 4800 MT/s and 1.1V, matching the ThinkMate platform specification.
