What this product is

The A-Tech 64GB DDR5 4800 ECC RDIMM is a registered server memory module built with Micron chipset components. It operates at 4800 MT/s with a CAS latency of 40 and runs at the standard 1.10 V. The module uses a 288-pin form factor and a 2Rx4 organisation for high-density capacity in a single stick.

Who this suits and who it does not

This module suits administrators upgrading Micron-based servers that require registered ECC DDR5 memory in a 64 GB density. It is not for desktop PCs or laptops that accept only unbuffered non-ECC DIMMs. Buyers who need a heat spreader or a lower latency rating should look at a different product.

What to check before ordering

Confirm that your system supports DDR5 registered ECC RDIMMs and that the memory controller can address a 64 GB 2Rx4 module at 4800 MT/s. Verify the motherboard has free 288-pin DDR5 slots and consult the vendor’s qualified-vendor list for this exact Micron part number. Ensure the platform accepts 1.10 V operation without additional voltage configuration.

Questions about this item

Does my server need DDR5 RDIMM slots that accept 288-pin modules running at 1.1 V?

Yes, this is a 288-pin DDR5 RDIMM that operates at 1.1 V, so the motherboard must provide DDR5 registered DIMM slots with that voltage.

Can I install this 64 GB 2Rx4 ECC RDIMM alongside existing DDR5 4800 ECC RDIMMs of different capacity?

Mixing is possible if the platform supports mixed-capacity DDR5 ECC RDIMMs at 4800 MT/s, but the memory controller will run all modules at the lowest common speed and timing.

How can I confirm the module is detected at 4800 MT/s with ECC active after installation?

Check the BIOS memory information or the OS memory report — both should show 64 GB at 4800 MT/s with ECC enabled and the correct 2Rx4 rank configuration.
