64 GB DDR5 kit for MSI X670E

This 64 GB kit contains four 16 GB DDR5 UDIMMs validated for the MSI X670E Gaming Plus WiFi motherboard. Each module runs at 4800 MT/s with CL40 latency at 1.1 V. The unbuffered, non-ECC design targets desktop builders who need a straightforward capacity upgrade for that specific platform.

DDR5 4800 speed ceiling and density limit

The kit operates at the base DDR5 4800 data rate with PC5-38400 bandwidth. Four single-rank 1Rx8 modules fill all four DIMM slots, reaching the board's maximum supported capacity without requiring registered or ECC memory. Higher frequencies or lower latencies are not supported by this validated configuration.

Simple four-module installation

Modules insert into the 288-pin slots without a heat spreader, keeping height low for cooler clearance. The main risk is mixing these validated sticks with other kits or populating slots in the wrong order, which can prevent the system from posting at the rated speed.

Questions about this item

Should I choose the 4 x 16 GB kit or a different capacity for my MSI X670E Gaming Plus WiFi motherboard?

The 4 x 16 GB kit fills all four slots on the MSI X670E Gaming Plus WiFi, giving 64 GB total at DDR5 4800 CL40 with 1.10 V and 1Rx8 organisation.

What does the DDR5 4800 speed mean for real-world performance on this motherboard?

On the MSI X670E Gaming Plus WiFi the modules run at 4800 MT/s with CL40 latency, delivering the standard JEDEC DDR5 4800 bandwidth without manual overclocking.

Does the 288-pin DDR5 UDIMM interface limit the speed or capacity I can use?

The 288-pin DDR5 UDIMM form factor matches the motherboard slots exactly; the kit is validated at 4800 MT/s CL40 1.10 V, so the interface does not impose a lower cap.
