Server memory for ThinkMate GPU systems

This 256 GB kit contains two 128 GB DDR5 ECC RDIMM modules built for ThinkMate GPX-QH24-24E4-8GPU and GPX-QH14-28E4-8HGX servers. Registered buffering and on-die error correction protect data integrity in GPU-dense workloads. The kit targets administrators expanding memory capacity in these qualified platforms.

Thermals and power

Modules operate at 1.1 V without heat spreaders, relying on chassis airflow for cooling. DDR5 architecture moves the power-management IC onto each DIMM, reducing rail current compared with previous generations. Registered clock drivers add negligible latency while stabilising signal integrity across 288 pins.

Deciding specification

Capacity is fixed at 256 GB in a two-module 4Rx4 configuration running at 4800 MT/s with CL40 timing. Servers needing different densities, speeds or rank layouts cannot use this kit. Verify slot count and maximum supported capacity before ordering.

Questions sur cet article

How do I install the 288-pin DDR5 RDIMM modules in my ThinkMate GPU server and which step is often missed?

Power down the server, open the chassis, align each 288-pin module with the DDR5 slot key notch, press firmly until both retention clips click, then verify in BIOS that all 256GB are detected at 4800 MT/s; the step most often missed is seating both clips fully on each 128GB stick.

What maintenance or replacement will this ECC registered memory need over its service life?

The modules have no heat spreaders and require no scheduled maintenance; ECC corrects single-bit errors on the fly, but if a 4Rx4 rank develops uncorrectable errors the only remedy is replacing the affected 128GB module under the lifetime replacement guarantee.

What limit appears first when the kit runs sustained workloads at 4800 MT/s?

The primary limit is the CL40 latency at 1.10V; sustained heavy traffic will hit the timing budget before thermal throttling becomes an issue because the registered design and low voltage keep module temperatures within spec.
