32GB DDR5 4800 UDIMM for Gigabyte B650

This 32GB DDR5 4800 CL40 UDIMM is built for Gigabyte B650 AM5 motherboards. It runs at 1.10V without a heat spreader and uses major-brand Samsung, Micron or Hynix chips. The single 288-pin module installs in minutes to add 32GB of non-ECC unbuffered memory.

Suits single-slot upgrades on B650 boards

Builders who need a single 32GB stick for a Gigabyte B650 platform get validated compatibility and 2Rx8 organisation. Systems that require ECC error correction, registered buffering or lower CAS latency should look at a different specification.

4800 MT/s DDR5 speed decides fit

The module operates at DDR5 4800 (PC5-38400) with CL40 timing at 1.10V. If the motherboard or CPU memory controller cannot run at this data rate, the kit will not deliver the rated performance.

Questions about this item

Will the 288-pin DDR5 UDIMM fit the DIMM slots on my Gigabyte B650 Eagle AX motherboard?

Yes, the module uses the standard 288-pin DDR5 UDIMM form factor that matches the four DIMM slots on the Gigabyte B650 Eagle AX board.

Do I need to enable anything in the BIOS after inserting the 32GB 4800 CL40 stick, or is it plug-and-play at 1.10V?

The module runs at 4800 MT/s and 1.10 V by default; insert it firmly until the retention clips click, then power on — no manual BIOS changes are required for base operation.

Since the module has no heat spreader, will the Samsung, Micron or Hynix chips need active airflow or replacement over time?

DDR5 chips at 1.10 V run cool enough for standard case airflow; no active cooling or periodic replacement is needed for the memory itself.
