Matched-pair DDR4 kit for MSI Z390 and Z490 boards

This 8 GB kit contains two 4 GB DDR4 modules rated at 2400 MT/s with CL17 timings. It is built specifically for MSI Z390-A PRO and Z490-A PRO motherboards. The unbuffered, non-ECC DIMMs operate at 1.2 V and use a 288-pin layout.

Capacity headroom on four-slot platforms

Two slots are populated, leaving two free for future expansion up to the board maximum of 128 GB. The dual-rank 2Rx8 organisation provides good density per module. A 64-bit operating system is required to address more than 4 GB of memory. All installed memory will run at the speed of the slowest module or the processor limit.

Plain green PCB without heat spreaders

The modules lack heat spreaders, keeping the profile low for tight CPU cooler clearances. Major-brand DRAM chips are used rather than generic ICs to reduce compatibility risk. Computer Memory Solutions backs the kit with a limited lifetime warranty against manufacturing defects when purchased directly.

Questions about this item

Will this 2400 MHz DDR4 kit run at its rated speed if I keep my current slower modules installed?

All memory in the system will run at the slowest installed module or CPU capability, so the kit will downclock to match existing slower modules.

How can I verify the kit is operating at CL17 2400 MHz after installation?

Enter the BIOS or use a system-information tool; the memory should report 2400 MT/s and timings of 17-17-17 at 1.2 V.

Does the package include only the two 4 GB sticks or are any accessories supplied?

The box contains exactly two 288-pin DDR4 DIMMs; no cables, screws or additional hardware are included.
