48GB DDR5 UDIMM for MSI B650M Project Zero

This single 48GB DDR5 4800 CL40 module is built for the MSI B650M Project Zero motherboard. It runs at 1.1V with 2Rx8 unbuffered non-ECC chips on a 288-pin PCB. The part number MD38400-4828K1 confirms validated compatibility. Ideal for a direct capacity upgrade on that platform.

Suits builders targeting this exact board.

Buyers who need memory for a different motherboard or laptop should look elsewhere because this kit is qualified only for the MSI B650M Project Zero. Systems that require ECC or registered DIMMs cannot use this unbuffered non-ECC module. Multi-module buyers must verify slot population rules independently.

48GB single-module capacity

The 48GB density in one stick lets you reach high total memory without occupying multiple slots on the MSI B650M Project Zero. This matters when the board has limited DIMM slots or when you plan to add a second identical module later. The 2Rx8 organisation supports the platform's memory controller at 4800 MT/s.

Questions about this item

Does the 1.1V DDR5 module run hot or draw enough power to need extra cooling when the system is under load all day?

At 1.1V the stick operates at standard DDR5 voltage, so it does not require additional cooling beyond normal case airflow.

What motherboard slot and memory controller does the PC need to accept this 288-pin 2Rx8 UDIMM?

A motherboard with a DDR5 288-pin UDIMM slot and a memory controller that supports 4800 MT/s non-ECC unbuffered memory, such as the MSI B650M Project Zero.

Will this CL40 2Rx8 stick work alongside my existing DDR5 memory if I keep the older kit installed?

Mixing is possible only if the other kit is also DDR5 288-pin UDIMM running at 1.1V; the system will default to the lowest common speed and loosest timings.
