Capacity and Compatibility

This kit provides 192GB of DDR5 memory across four 48GB modules. It is built for desktop PCs using the MSI X670E Gaming Plus WiFi motherboard and similar platforms that accept 288-pin UDIMMs.

Thermals and Power

The modules operate at 1.1V with a CAS latency of CL40 and run at 4800MHz. They have no heat spreader, so airflow inside the case handles cooling. Power draw scales with the four-module population.

Package Contents

The box contains the four UDIMM modules only. No additional software, cables or brackets are included. The memory is validated for stability on the target MSI board before shipping.

Questions about this item

How do I install the 4x48GB DDR5 4800 kit on the MSI X670E Gaming Plus WiFi board?

Power off, open the case, align the notch on each 288-pin UDIMM with the slot key, press firmly until the retention clips click, then enable EXPO in BIOS to run at 4800 MT/s CL40.

What maintenance or replacement will the 192GB DDR5 kit need later?

No routine maintenance is required; keep the slots dust-free and if a module fails it is covered by a lifetime replacement warranty.

What limit appears first under sustained load with these CL40 1.1V modules?

The primary limit is the CAS latency of 40 cycles at 4800 MT/s, which governs access timing during prolonged workloads.
