512 GB ECC registered DDR5 kit

This 512 GB kit contains four 128 GB DDR5 R-DIMM modules rated at 6400 MT/s with CL52 timings and 1.1 V operation. It is built for AMD TRX50 or WRX90 and Intel W790 or W890 workstation and server motherboards that support registered ECC memory.

Installation and compatibility notes

The modules use the standard 288-pin DDR5 RDIMM form factor and seat in the corresponding server or workstation DIMM slots. They are not compatible with desktop or laptop platforms, so verifying motherboard support for registered ECC DDR5 at this capacity and speed is essential before fitting.

Sustained-load behaviour

On-board ECC detects and corrects single-bit errors while a built-in thermal sensor monitors temperature up to 85 °C to maintain stability during long compute runs. Registered buffering reduces electrical load on the memory controller, helping consistent throughput in multi-threaded server workloads.

Questions about this item

How can I confirm the kit is running at DDR5 6400 with CL52 timings after installation?

Check the BIOS or a tool such as CPU-Z; the memory should report 6400 MT/s and timings of 52-52-52-103 at 1.1 V.

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

The package contains four 128 GB 288-pin DDR5 RDIMMs with Hynix ICs and on-board thermal sensors; no extra parts are needed if your motherboard supports registered ECC DDR5.

When should I choose this 512 GB (4 × 128 GB) DDR5-6400 CL52 kit over other capacities or speeds?

Select this kit when your workstation or server board (for example AMD TRX50/WRX90 or Intel W790/W890) requires registered ECC memory at 6400 MT/s and you need the full 512 GB capacity.
