192GB DDR5 Kit for MSI Z790 Project Zero

This 192GB kit contains four 48GB DDR5 UDIMM modules rated at 5600MHz with CL46 latency and 1.1V operation. It is built for the MSI Z790 Project Zero motherboard and uses unbuffered non-ECC memory with a 2Rx8 organisation. The modules have no heat spreader and fit standard 288-pin desktop slots.

Suited for high-capacity desktop workloads

This kit suits users who need the full 192GB capacity on an MSI Z790 Project Zero system and can accept CL46 timings at 5600MHz. Builders who require ECC error correction, registered modules, lower CAS latency, or a heat spreader should look at other memory. Systems that do not support 48GB density DDR5 UDIMMs cannot use this kit.

48GB per module density at 5600MHz DDR5

The decisive specification is the 48GB per module density combined with DDR5 5600 speed. The motherboard must explicitly support 48GB non-ECC UDIMM modules at this frequency for the kit to function. Verify the board’s qualified vendor list for part number MD44800-4828K4 before purchase.

Questions about this item

What is the CAS latency of these DDR5 modules?

The kit runs at CL46, which is the primary timing you will see under sustained workloads.

How much power do the four sticks draw at 1.1 V during all-day operation?

Each 48 GB module operates at 1.10 V, so the total voltage remains 1.1 V across the kit; actual wattage depends on your motherboard's memory controller and load.

Does the MSI Z790 Project Zero motherboard need a BIOS update before installing this 192 GB kit?

The memory is validated for the MSI Z790 Project Zero platform; check the motherboard manufacturer's support page for the latest BIOS that enables full 4 x 48 GB capacity.
