256GB DDR5 4800 ECC RDIMM Kit

This 256GB kit contains two 128GB DDR5 4800 registered ECC RDIMMs built for the THINKMATE GPX-XH20-28S4-8HGX server platform. It targets administrators who need high-density registered memory with error correction for GPU-optimised workloads. Modules run at 1.1V with CL40 latency and a 4Rx4 organisation.

Installing 288-Pin Registered DIMMs

Installation follows standard 288-pin DDR5 RDIMM procedure; seat each module firmly until the retention clips engage. Common issues include mixing registered and unbuffered DIMMs, populating slots in the wrong sequence for the platform, or failing to update the system BIOS before adding high-capacity 4Rx4 modules.

Verify Slot Count and Population Rules

Before ordering, confirm the server has enough free 288-pin DDR5 slots and check the vendor memory population guide for 4Rx4 DIMM placement order. Ensure the platform supports 128GB per module at 4800 MT/s with registered ECC operation. Mixed-rank or mixed-voltage configurations are not supported by this kit.

商品問答

How can I confirm the kit is running at the rated 4800 MT/s and CL40 after installation?

Enter the system BIOS or UEFI and check the memory frequency and timing tables; they should show 4800 MT/s with CAS latency 40 at 1.1 V.

What exactly ships in the box and is anything else required to use the modules?

The package contains two 128 GB DDR5 4800 ECC registered RDIMMs — 256 GB total — and no extra cables, brackets or software are needed.

Which version of this kit should I choose for the Thinkmate GPX-XH20-28S4-8HGX server?

Select the 256 GB kit (2 × 128 GB) with part number MR38400-744K2; it matches the server’s DDR5 4800 ECC RDIMM 4Rx4 specification.
