64GB DDR4 2666 Kit for MSI Motherboards

This 64GB kit contains two 32GB DDR4 2666 DIMMs built for MSI MPG Z490 GAMING PLUS, MPG Z490M GAMING EDGE WIFI and PRESTIGE X570 CREATION boards. It suits users who need the full 64GB capacity on these specific platforms. Buyers with other motherboards or who require ECC memory should look elsewhere.

Installing the Matched Pair

The two modules are tested together and install in the standard 288-pin DIMM slots. Seat each stick firmly until the retention clips click. Mixing these modules with existing memory will force all modules to run at the speed of the slowest kit or the processor limit.

Check Slots and OS Before Ordering

Verify your board has free DIMM slots; the compatible models listed support up to 128GB across four sockets. A 64-bit operating system is required to address more than 4GB of memory. Confirm your CPU and current memory configuration can utilise the full 64GB at 2666MHz.

Questions about this item

How can I confirm the kit is running at DDR4 2666 CL19 after installation?

Enter the BIOS or use a tool such as CPU-Z and verify the memory frequency shows 2666 MHz with timings of 19-19-19.

What does the package contain and is anything else required to install it?

The box includes two 32 GB 288-pin DDR4 DIMMs; no extra cables or brackets are needed, just a compatible motherboard with free slots.

Should I choose this 64 GB kit or the 128 GB option for my MSI board?

This kit provides 64 GB total in two modules; if your workload needs more than 64 GB and your board supports 128 GB across four slots, the larger kit would be appropriate.
