NEMIX RAM 64GB DDR5 4800 Kit

This NEMIX RAM kit provides 64GB of DDR5 memory across four 16GB modules running at 4800MT/s with CL40 latency. It uses unbuffered non-ECC UDIMMs built with major-brand DRAM chips and operates at the standard 1.1V. The 288-pin modules are designed for desktop motherboards that support DDR5.

Suited for MSI B650M Project Zero builds

The kit is validated for the MSI B650M Project Zero motherboard, so builders using that board can install it with confidence. Systems requiring ECC error correction or registered modules cannot use this memory. Buyers who need more than 64GB of capacity or lower latency timings should look at other options.

Four modules fill four slots for 64GB

Populating all four slots delivers the full 64GB capacity, which handles heavy multitasking, content creation and gaming workloads comfortably. The CL40 timing and 4800MT/s speed provide standard DDR5 bandwidth; applications that scale with tighter latencies or higher frequencies will not reach their peak on this kit.

Questions about this item

Do I need a motherboard with 288-pin DDR5 slots to install this kit?

Yes, the modules are 288-pin DDR5 UDIMMs and require a motherboard that supports DDR5 memory.

Will these modules run at 4800 MT/s on an MSI B650M Project Zero motherboard?

The kit is rated for DDR5 4800 (PC5-38400) and is listed as compatible with that board, so it will operate at that speed when XMP or EXPO is enabled.

How can I verify the kit is running at CL40 1.10 V after installation?

Check the memory tab in CPU-Z or the BIOS memory information screen; it should show 4800 MT/s, CL40 timings and 1.10 V.
