System-Specific DDR5 Kit for MSI Z790 Project Zero

This 64 GB kit contains four 16 GB UDIMMs built for the MSI Z790 Project Zero motherboard. Each module runs at DDR5 4800 with CL40 latency at 1.1 V. The unbuffered non-ECC design targets desktop builders who want validated compatibility without manual tuning.

Single-Deciding Specification: DDR5 4800 CL40

The modules operate at the JEDEC base speed of 4800 MT/s with a CAS latency of 40 cycles. This timing and voltage combination is the primary filter for stability on the target board. Builders needing tighter timings or higher frequencies must look elsewhere.

Capacity and Headroom: 64 GB Across Four Slots

The 4 × 16 GB layout fills all four DIMM slots on the motherboard, delivering 64 GB total for heavy multitasking, content creation or virtualisation workloads. With every slot populated, further expansion requires replacing modules rather than adding them.

Questions about this item

What does the DDR5 4800 speed mean once the kit is installed in my MSI Z790 Project Zero board?

The four 16 GB modules run at 4800 MT/s with CL40 timing at 1.1 V, delivering the rated PC5-38400 bandwidth on the 288-pin DDR5 UDIMM interface.

How does the PC5-38400 rating relate to the DDR5 4800 interface on this kit?

PC5-38400 is the module designation that corresponds to the DDR5 4800 data rate on the 288-pin UDIMM standard used by this memory.

What physical space and power connectors do the four 16 GB sticks need to fit the motherboard?

Each stick is a standard 288-pin DDR5 UDIMM without a heat spreader, drawing 1.1 V from the DIMM slot itself; no extra power cables or oversized clearance are required.
