Gigabyte B650 compatible DDR5 kit

This 64 GB kit contains two 32 GB DDR5 UDIMMs validated for the Gigabyte B650 AORUS Elite AX motherboard. The modules run at 5600 MT/s with CL46 latency at 1.10 V. They are unbuffered, non-ECC and use a 2Rx8 organisation. Builders upgrading that specific board can install the pair without further configuration.

288-pin unbuffered layout

Each stick uses the standard 288-pin DDR5 UDIMM form factor and carries no heat spreader. The low 1.1 V operating voltage keeps power draw modest for a desktop memory upgrade. Because the modules are unbuffered, they slot directly into the board's DIMM sockets without registered buffering. The bare PCB design fits tight clearances around large CPU coolers.

DDR5 5600 baseline limits

The kit operates at the baseline DDR5 5600 speed (PC5-44800) with conservative CL46 timings. Systems that cannot run DDR5 at this data rate will not boot with these modules installed. The 2Rx8 density caps the kit at 64 GB across two slots, so boards with only two DIMM sockets cannot exceed this capacity. Buyers needing higher frequencies, lower latencies or ECC error correction must select a different specification.

Questions about this item

What DDR5 standard does this kit run at and what effective speed does that cap?

The kit uses DDR5 5600 (PC5-44800) so the JEDEC data rate caps at 5600 MT/s.

What physical slot and pin count does this 288-pin UDIMM need on the Gigabyte B650 AORUS Elite AX?

It requires a standard DDR5 UDIMM slot with 288 pins; the board has four such slots.

How are the two 32 GB modules installed and which slot order is the common mistake?

Insert both sticks into the same coloured slots — usually A2 and B2 — to enable dual-channel; putting them in adjacent slots A1 and A2 is the frequent error.
