16 GB DDR5 UDIMM for Gigabyte B650 Eagle AX

This 16 GB DDR5 4800 module is built for the Gigabyte B650 Eagle AX motherboard. It runs at PC5-38400 speed with CL40 latency at 1.1 V. The single-rank 1Rx8 design uses major OEM chips from Samsung, Micron or Hynix.

Builders upgrading the Gigabyte B650 Eagle AX

The kit fits the validated memory list for that board, so it installs without compatibility guesswork. Systems that require ECC or registered DIMMs will not accept this non-ECC unbuffered part. Users needing more than 16 GB should add additional modules.

CL40 CAS latency at DDR5 4800

The CL40 timing is the key spec that determines whether this module matches the board's supported memory profile. If the platform demands a different latency, this stick will not operate at its rated speed.

Questions about this item

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

Yes, the 288-pin DDR5 UDIMM form factor matches the four DDR5 slots on the GIGABYTE B650 Eagle AX, and the 1.1 V operating voltage is the standard for DDR5 on that platform.

What is the correct way to seat this single 16 GB module, and what step do builders often miss?

Align the notch on the module with the key in the slot, press down firmly until both side latches click shut, then verify in BIOS that the memory is running at DDR5 4800 with CL40 timings; the step most often missed is enabling the EXPO or XMP profile to reach the rated speed.

Does this non-ECC unbuffered kit require any firmware updates or periodic maintenance after installation?

No scheduled maintenance is needed for the memory itself; keep the motherboard BIOS current to ensure continued compatibility and stability, and the module is covered by a lifetime replacement warranty if a fault ever develops.
