48GB DDR5 UDIMM for MSI Z790

This single 48GB DDR5 module runs at 5600MHz with CL46 latency and 1.1V operation. It is built as a 2Rx8 unbuffered non-ECC UDIMM using major OEM chips from Samsung, Micron or Hynix. The kit targets owners of the MSI Z790 Project Zero motherboard who need a straightforward capacity increase.

Thermals and power at stock settings

Operating at the standard 1.1V DDR5 voltage keeps power draw low and heat output modest during everyday workloads. No heat spreader is fitted, so the bare PCB relies on case airflow for cooling. The module runs at JEDEC speeds without overclocking, avoiding extra thermal load.

Build notes and daily handling

The 288-pin UDIMM form factor fits the designated DDR5 slots on the compatible board. Lacking a heat spreader, the module sits lower than many alternatives, which can ease clearance near large CPU coolers. Installation follows the usual UDIMM procedure and requires no special tools or configuration.

Questions about this item

How do I install this 48GB DDR5 5600 UDIMM in my MSI Z790 Project Zero motherboard?

Power off the PC, open the case, align the 288-pin module with the DDR5 slot notch, press firmly until both retention clips click, then power on and verify 48GB at 5600 MT/s in BIOS.

What maintenance or replacement will this 1.1V DDR5 module need later?

No scheduled maintenance is required; keep the slot and contacts dust-free and ensure the CPU cooler does not stress the module, otherwise it runs until a fault occurs.

What limit appears first when this CL46 2Rx8 kit runs sustained workloads?

The CAS latency of 46 cycles at 5600 MT/s sets the baseline response time; sustained loads will hit that timing ceiling before thermal or voltage limits become a factor.
