Capacity and Compatibility

This is a 64GB DDR5 memory kit built as four 16GB UDIMM modules. It runs at 5600MT/s with a CAS latency of CL46 and operates at 1.1V. The kit is validated for the ASUS ROG Strix B650-A motherboard and uses unbuffered non-ECC chips from major OEM suppliers.

Who It Suits

Builders upgrading an ASUS ROG Strix B650-A system who need 64GB of DDR5 memory in a single matched kit will find this configuration convenient. Buyers who need ECC error correction, registered modules, lower latency timings or a heat spreader should look at a different specification.

Deciding Specification

The 288-pin DDR5 UDIMM form factor with 1Rx8 organisation and 1.1V operation is the single detail that determines whether this kit fits the target board and memory controller.

Questions about this item

Will the 288-pin DDR5 UDIMM modules fit the four DIMM slots on the ASUS ROG Strix B650-A?

Yes, the 288-pin DDR5 UDIMM form factor matches the motherboard's four DDR5 slots, so all four 16 GB modules install directly without adapters.

What BIOS step is often missed when installing this 5600 CL46 kit?

After seating the modules, enter the BIOS and enable the EXPO or XMP profile so the memory runs at the rated 5600 MT/s CL46 instead of the default JEDEC speed.

How long before the 1.1 V Samsung, Micron or Hynix chips typically need replacement?

DDR5 DRAM at 1.1 V has no scheduled replacement interval; modules normally last the useful life of the system unless a rare defect appears.
