64GB DDR5 5600 UDIMM Kit

This NEMIX RAM kit provides 64GB of DDR5 memory in two 32GB unbuffered UDIMM modules. It runs at 5600MT/s with CL46 latency at 1.1V and uses 288-pin 2Rx8 organisation. The kit is validated for MSI Z790 Project Zero motherboards.

Builders confirmed on MSI Z790 Project Zero

This memory suits builders who have verified their board matches the validated MSI Z790 Project Zero platform and want a 64GB DDR5 upgrade. It is not for systems that require ECC error correction, registered modules, a different DDR generation, or any motherboard outside the validated compatibility list.

288-pin DDR5 UDIMM form factor

The 288-pin DDR5 UDIMM form factor is the single specification that decides fit. Modules with a different pin count, DDR generation or buffered design will not seat or function in the target board.

Questions about this item

How do I install the 288-pin DDR5 UDIMM modules on the MSI Z790 Project Zero motherboard, and what step is often missed?

Align the notch on each 32 GB stick with the slot key, press down firmly until both side clips click, then enable the 5600 MT/s profile in BIOS so the kit runs at its rated speed instead of the default JEDEC setting.

What maintenance or replacement will the 64 GB DDR5 kit need over time?

No scheduled maintenance is required; the unbuffered non-ECC modules have no heat spreader, so keep case airflow adequate, and replace a stick only if memory diagnostics report errors.

What limit appears first when the 2Rx8 CL46 1.10 V modules run under sustained load?

The CAS latency of 46 cycles at 5600 MT/s sets the timing ceiling; without a heat spreader, thermal throttling may occur before voltage or rank limits are reached.
