System-specific DDR5 kit

This 64GB kit contains two 32GB DDR5 5600 CL46 modules built for the MSI MAG B650 Tomahawk WiFi motherboard. The unbuffered non-ECC UDIMMs operate at 1.1V and use a 2Rx8 organisation. They are intended for desktop PC upgrades that require this exact specification. Builders using a different platform should verify compatibility before purchase.

Major OEM chips on plain PCB

Samsung, Micron or Hynix ICs are assembled without a heat spreader, keeping the modules low-profile for tight CPU cooler clearance. The standard 288-pin DDR5 edge connector fits any desktop UDIMM slot, while the unbuffered design means no register delay for typical consumer workloads. Installers should confirm the motherboard supports 2Rx8 density at 5600 MT/s.

Standard DDR5 voltage and density

At 1.1V the kit runs at the base DDR5 voltage, so power draw stays within normal limits for a two-module configuration. The CL46 latency and 5600 MT/s data rate produce typical heat output for JEDEC-spec memory, requiring only standard case airflow. No extra cooling or elevated voltage is needed for rated operation.

Questions about this item

What speed and latency does the DDR5 5600 kit run at?

The modules operate at DDR5 5600 with a CAS latency of CL46 and 1.10V voltage.

Will the 288-pin UDIMM modules fit the MSI MAG B650 Tomahawk WiFi motherboard?

Yes, the 288-pin DDR5 UDIMM form factor matches the motherboard's DIMM slots.

How do I install the 2Rx8 dual-rank modules correctly?

Insert both sticks into the same-channel slots (usually A2 and B2) until the retention clips click.
