64GB DDR5 Kit for MSI B760M Project Zero

This 64GB kit contains four 16GB DDR5 UDIMM modules rated at 4800MHz with CL40 latency. It is built specifically for the MSI B760M Project Zero motherboard and runs at the standard 1.1V voltage. The modules use 1Rx8 organisation and major OEM chips from Samsung, Micron or Hynix.

Unbuffered Non-ECC Design

The kit uses unbuffered non-ECC DDR5 UDIMMs without heat spreaders. This keeps the physical profile low for tight clearance while maintaining direct compatibility with the target MSI board. No additional software or drivers are required; the memory operates at its rated JEDEC speed immediately after installation.

Capacity Headroom for Multitasking

Four populated slots deliver 64GB of total capacity, which handles heavy multitasking, content creation and virtual machines comfortably. The board's four DIMM slots are fully occupied, so no further memory expansion is possible without removing modules. Builders needing more than 64GB must choose a different platform.

Questions about this item

Will the 1Rx8 DDR5 chips on these four 16GB modules need replacement under normal desktop use?

The modules use major-brand Samsung Micron or Hynix ICs and carry a lifetime replacement warranty, so no routine chip replacement is expected.

What limit appears first when the kit runs at 4800 MT/s continuously?

The CL40 latency at 1.10 V is the primary timing constraint under sustained load.

How much heat and power does the 64GB kit produce during all-day operation?

At 1.1 V with no heat spreaders the modules run cool and draw minimal power for DDR5 4800 operation.
