48 GB DDR5 module for MSI Z790

This 48 GB DDR5 4800 UDIMM is built for MSI Z790 Project Zero motherboards. It runs at PC5-38400 with CL40 latency and 1.1 V. The single 2Rx8 stick adds high-density memory without filling extra slots.

No heat spreader or software included

The bare module ships without a heat spreader, keeping the profile low for tight CPU coolers. No bundled utilities or RGB controllers are supplied, so the memory operates at standard JEDEC timings out of the box.

Suits builders expanding Z790 capacity

Ideal for users who need 48 GB on a compatible MSI board and prefer a single-slot upgrade. Not for systems that require ECC error correction, registered buffering, lower CAS latency or a heat spreader for sustained heavy loads.

Questions about this item

Will the 48GB DDR5 module need any firmware updates or component replacements over its lifespan?

No firmware updates or component replacements are required; the module is a solid-state DRAM stick with no moving parts or field-updatable firmware.

What limit appears first when the 4800 CL40 kit runs at full load for hours?

The JEDEC-defined 1.10 V operating voltage and CL40 latency are the fixed electrical limits; the module does not exceed either under sustained use.

How much heat and noise does the 288-pin UDIMM produce during all-day operation?

The module has no heat spreader and no fan, so it runs silently; thermal output stays within standard DDR5 UDIMM limits at 1.1 V.
