Kingston Server Premier 32GB DDR5-6400 ECC RDIMM

Exact component, clear contents

1 × Kingston Server Premier 32GB ECC RDIMM, manufacturer part KSM64R52BD8-32MH.

This is a single memory component. No motherboard, CPU, GPU, SSD or assembled computer is supplied. A multi-module memory kit is not included.

Use cases and limits

Consider ECC RDIMM memory when planning a supported server or workstation for local-AI host workloads, virtual machines, data preparation or other compute tasks. Start with the platform and memory support list, then choose capacity, rank, speed and the number of modules. A larger host-memory budget does not automatically let a GPU hold a larger model.

Platform checklist

• Confirm that the CPU and motherboard support registered DDR5, not only unbuffered DDR5.
• Look up KSM64R52BD8-32MH in the system or motherboard memory support list and confirm any required BIOS.
• Follow the manual’s DIMM population and channel rules. Avoid mixing module types or assuming different speed tiers are interchangeable.
• Check total supported capacity and the speed allowed with your selected number of modules.

Frequently asked questions

Is this one module or a 32GB kit?

You receive one 32GB Kingston module, not a two-module kit. Match the number of modules and channel population to your platform documentation.

Will it work in an ordinary DDR5 desktop motherboard?

Do not assume so. This is registered ECC DDR5 (RDIMM). Check explicit RDIMM support and the exact module part number in your motherboard or system memory support list.

Is DDR5 on-die ECC the same as registered ECC memory?

No. This module has on-die ECC and an x80 ECC organisation. Do not treat the presence of on-die ECC in another DDR5 product as evidence that it is interchangeable with this RDIMM.

Will the module always run at 6400 MT/s?

The module is rated at 6400 MT/s. The CPU memory controller, BIOS, motherboard and installed DIMM population determine the operating rate. Verify the supported configuration before ordering.

Can this RAM increase the VRAM of my graphics card?

No. System memory and GPU memory are separate resources. Choose host memory and GPU VRAM independently around the workload and software you intend to run.

Is this a ready-to-use AI computer or mining rig?

No. This listing is a memory component. It does not include a CPU, motherboard, GPU or complete system, and no AI throughput or mining profitability is promised.

Compare and plan your build

Compare our 32GB DDR5-5600 ECC RDIMM for a different rated-speed tier. Select by platform support—not price or speed alone. The alternatives are not a pre-validated mixed-memory kit.
