64GB DDR5 Kit for Gigabyte B650I AORUS Ultra

This 64GB kit contains two 32GB DDR5 5600 modules built for the Gigabyte B650I AORUS Ultra motherboard. It suits builders who need maximum capacity on a two-slot Mini-ITX board. Buyers who want more storage or a different motherboard platform should look elsewhere.

Standard 288-Pin UDIMM Build Without Heat Spreaders

The modules use a plain 288-pin UDIMM form factor and run at 1.10V with no heat spreaders attached. This keeps the profile low for tight Mini-ITX layouts but offers no extra thermal surface. Builders who need a second card or oversized cooler clearance gain nothing from this design.

DDR5 5600 CL46 2Rx8 Density Limits

Each 32GB module is dual-rank 2Rx8 at CL46 latency, reaching the standard DDR5 5600 (PC5-44800) speed. Four ranks across two slots can stress the memory controller on some Mini-ITX boards. Users who need lower latency or single-rank stability will not find it here.

Questions about this item

Does the DDR5 5600 PC5-44800 rating cap the actual transfer rate at 5600 MT/s?

Yes, the kit is rated for DDR5 5600 which runs at 5600 MT/s with PC5-44800 bandwidth.

Will the 288-pin UDIMM modules fit the two DIMM slots on the Gigabyte B650I AORUS Ultra mini-ITX board?

Yes, each 32 GB module uses the standard 288-pin DDR5 UDIMM form factor that matches the board's two slots.

What is the correct way to seat both 2Rx8 sticks so the board recognises the full 64 GB?

Insert each stick vertically until the side clips click; a common mistake is stopping before the clips engage, leaving the module partially seated.
