System-Specific 512GB DDR5 Kit

This 512GB kit contains four 128GB DDR5 4800MHz ECC registered DIMMs built for the ThinkMate GPX-XH20-28S4-8HGX GPU-optimized server. IT professionals managing mission-critical workloads in that platform receive validated capacity and error correction.

Registered ECC Limits on DDR5 4800

Registered ECC RDIMMs add a clock cycle for command buffering, which stabilises heavy loads but caps the effective data rate at the JEDEC 4800MT/s baseline. The 4Rx4 organisation increases density per module while requiring the memory controller to support quad-rank addressing.

Straightforward DIMM Installation

The 288-pin modules seat in standard DDR5 server slots without tools; align the key notch, press until the ejectors click, and confirm population order in the system manual. Common issues arise when mixing ranks or skipping the required BIOS update for 128GB density support.

商品問答

Should I choose the 4×128GB kit or look for a different capacity for the ThinkMate GPX-XH20-28S4-8HGX?

The kit supplies 512GB total across four 128GB modules; select it when your server needs that exact capacity and has four free DDR5 RDIMM slots.

What does the DDR5 4800 CL40 rating deliver once installed in the ThinkMate GPU-optimised server?

The modules run at 4800 MT/s with CL40 latency and 1.10V, providing registered ECC bandwidth of PC5-38400 for stable throughput under heavy GPU workloads.

How does the 288-pin DDR5 RDIMM interface and 4Rx4 organisation limit real-world use in this system?

The 288-pin registered DDR5 form factor fits only DDR5 RDIMM slots, and the 4Rx4 rank structure counts as four logical ranks per module — verify the platform supports four ranks per channel before installing all four sticks.
