DDR5 4800 UDIMM kit for Gigabyte B650 Eagle AX

This 64GB kit contains four 16GB DDR5 4800 UDIMM modules that run at 1.1V with CL40 timing. The memory is non-ECC and unbuffered, built with major OEM chips from Samsung, Micron or Hynix. It is designed specifically for the Gigabyte B650 Eagle AX AM5 motherboard.

Suits builders upgrading that exact Gigabyte B650

If your system uses a different motherboard or requires ECC, registered modules or a different DDR5 speed, this kit will not match those requirements. Buyers who need heat spreaders on every module should also look elsewhere.

No heat spreaders or extra software are included

The package delivers only the four UDIMM modules themselves. Without spreaders the sticks sit lower in tight slots, and the absence of bundled utilities means configuration relies entirely on the motherboard BIOS.

Questions about this item

Does my Gigabyte B650 Eagle AX motherboard need four free 288-pin DDR5 slots for this 64 GB kit?

Yes, the kit contains four 16 GB UDIMMs that each occupy one 288-pin DDR5 slot on the B650 Eagle AX.

Can I keep my existing DDR5 4800 CL40 1.1 V modules and add this kit without changing BIOS settings?

Matching speed, latency and voltage means the board will usually train all modules at 4800 MT/s CL40 1.1 V automatically.

How do I confirm the system is running the full 64 GB at DDR5 4800 CL40 after installation?

Open Task Manager or BIOS and verify 64 GB detected, speed showing 4800 MT/s and CAS latency at 40.
