NEMIX RAM 64GB DDR4 3200 ECC UDIMM Kit

This 64GB kit provides two 32GB DDR4 3200 modules with ECC error correction for data integrity. The unbuffered UDIMM design operates at 1.2V with CL22 latency and 2Rx8 organisation. It is validated for compatibility with Gigabyte B550-AORUS motherboards.

Builders adding ECC protection to a Gigabyte

This kit suits users who need error-correcting memory on a consumer chipset that supports unbuffered ECC. Buyers requiring registered or load-reduced modules for server platforms should look elsewhere, as this product is strictly unbuffered.

64GB capacity with DDR4 3200 headroom

The dual-rank 32GB modules fill two slots, delivering 64GB for virtualisation, ZFS storage or content-creation workloads. Systems needing more than 64GB or higher frequencies than 3200MT/s will exceed this kit's limits.

Questions about this item

Will this 288-pin DDR4 kit fit the four DIMM slots on my Gigabyte B550-AORUS motherboard?

Yes — the kit uses the standard 288-pin DDR4 UDIMM form factor that matches the four DDR4 slots on the B550-AORUS board.

If I add this 3200 CL22 kit, will my existing DDR4 modules run at their own rated speed or be limited by the new kit?

The board will run all installed modules at the lowest common speed and loosest timings; the CL22 rating on this kit sets the ceiling for the combined set.

How can I confirm the 64 GB ECC kit is running at 3200 MT/s with CL22 after I install it?

Open the BIOS or a tool such as CPU-Z and verify the memory frequency shows 3200 MT/s and the CAS latency reads 22.
