Target system and kit layout

This 128GB kit contains four 32GB DDR5 UDIMM modules validated for the MSI Z790 Project Zero motherboard. It runs at 4800 MT/s with CL40 timings at 1.10V and uses unbuffered non-ECC 2Rx8 chips from major DRAM vendors.

Who this suits and who it does not

Builders who need the maximum supported capacity on this specific board will use all four slots with a matched set. Systems limited to two DIMM slots, workloads that require ECC error correction, or users seeking lower latency or higher frequency kits should consider a different configuration.

The specification that decides fit

The 288-pin DDR5 UDIMM form factor at 4800 MT/s CL40 1.10V is the single parameter that determines whether this kit installs and runs without manual tuning on the target motherboard.

Questions about this item

Does the kit contain only the four 32 GB modules or are any cables or tools included?

The package contains only the four 32 GB DDR5 UDIMM modules. No cables, screws or installation tools are supplied.

The kit is listed as CL40 at 4800 MT/s. Is there a lower-latency or higher-speed version of this same 128 GB capacity?

This part number MD38400-328K4 is offered only at DDR5 4800 with CL40 timings. No alternative latency or speed bin is available for this kit.

Will the 4800 MT/s rating run at that speed automatically on the MSI Z790 Project Zero, or does it need manual setup?

The modules operate at the standard DDR5 4800 MT/s JEDEC speed and voltage of 1.10 V. The motherboard will configure them automatically without manual intervention.
