48GB DDR5 module for ASUS Z890 APEX

This 48GB DDR5 UDIMM runs at 5600MT/s with CL46 latency at 1.10V. It uses a 2Rx8 unbuffered non-ECC layout built from major OEM Samsung Micron Hynix chips. The single 288-pin stick is validated for the ASUS ROG Maximus Z890 APEX motherboard.

Builders upgrading the Z890 APEX to 48GB per slot

Suits anyone adding a single high-density module to that specific board without populating every slot. Not for systems that require ECC error correction or registered buffering. Not for platforms limited to lower DDR5 speeds or different pin counts. Not for buyers who need a heat spreader on every module.

Sustained load behaviour at 1.1V

Modules are stress tested under load to verify stability during extended workloads. The 1.10V operating voltage helps limit thermal output during long sessions. CL46 timing remains consistent across continuous operation. Rank organisation is 2Rx8 for predictable bandwidth scaling.

Questions about this item

Does my ASUS ROG Maximus Z890 APEX need a free 288-pin DDR5 UDIMM slot for this 48GB module?

Yes — the module is a single 288-pin DDR5 UDIMM, so one empty DDR5 DIMM slot on the Z890 APEX is required.

Can I keep my existing DDR5 5600 CL46 1.1V sticks and add this 48GB 2Rx8 module?

The board will train all installed DDR5 at a common speed and voltage; mixing ranks or capacities may force looser timings or a lower data rate.

How do I confirm the 48GB kit is running at 5600 MT/s with CL46 after installation?

Open the BIOS or a tool such as CPU-Z and verify the memory frequency reads 5600 MT/s and the CAS latency shows 46.
