Compatible 8 GB DDR4 3200 UDIMM

This NEMIX RAM module delivers 8 GB of DDR4 memory at 3200 MT/s with CL22 timing and 1.20 V operation. The 288-pin unbuffered non-ECC design uses a single-rank 1Rx8 organisation built from major OEM chips. It targets owners of a Gigabyte B550-AORUS motherboard who want a straightforward capacity increase.

Suits Gigabyte B550-AORUS builds.

Builders upgrading a Gigabyte B550-AORUS board gain a tested, compatible stick that installs in minutes. Systems requiring error-correcting code memory or registered modules cannot use this unbuffered non-ECC part. Buyers needing more than 8 GB per slot should look at higher-density alternatives.

1Rx8 single-rank layout decides platform fit

The 1Rx8 organisation determines how the memory controller addresses the module and affects maximum supported ranks per channel. Verify that your Gigabyte B550-AORUS firmware accepts this rank configuration before purchase.

Questions about this item

Will the CL22 timing limit real-world responsiveness on my B550-AORUS board?

CL22 is the standard JEDEC latency for DDR4-3200; the module runs at the rated 3200 MT/s without manual tuning, so everyday tasks see the full speed the platform supports.

Does the PC4-25600 rating guarantee 3200 MT/s on a B550-AORUS motherboard?

The board’s DDR4 controller tops out at 3200 MT/s, matching the module’s PC4-25600 spec, so the memory will operate at its rated transfer rate by default.

Will the 288-pin UDIMM fit the four DIMM slots on my B550-AORUS without clearance issues?

Yes — the stick uses the standard 288-pin DDR4 UDIMM form factor and has no heat spreader, so it seats cleanly in any of the board’s four slots.
