  • Validated compatibility with Gigabyte B650 Eagle AX ensures reliable integration

Capacity and compatibility

This 48 GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.10 V. It is built as a 2Rx8 unbuffered UDIMM for Gigabyte B650 Eagle AX motherboards on the AM5 platform.

Ideal use and limitations

The single stick suits builders adding 48 GB to a compatible board with a free 288-pin slot. It is not for systems that require ECC or registered DIMMs, nor for platforms that only accept a different DDR generation.

Deciding specification

The 48 GB density in a single rank-2Rx8 UDIMM at DDR5 4800 CL40 determines whether this kit matches the motherboard's qualified-vendor list and the memory controller's supported population rules.

Questions about this item

Does this 48GB DDR5 4800 CL40 module require a Gigabyte B650 Eagle AX motherboard with an AM5 socket to operate?

Yes, the module is built for Gigabyte B650 Eagle AX boards using the AM5 platform and will only work in a DDR5-compatible AM5 system.

Can I add this 48GB 2Rx8 DDR5 4800 stick next to the DDR5 DIMMs already installed in my B650 Eagle AX?

Yes, the single-rank-appearing 2Rx8 stick fits any free 288-pin DDR5 slot on that board and will run at the board's negotiated speed and voltage.

After installing the module, how do I confirm the system sees 48GB at DDR5 4800 CL40 1.10V?

Open the BIOS or a tool like CPU-Z and verify the memory tab shows 48 GB capacity, 4800 MT/s data rate, CL40 timings and 1.10 V operating voltage.
