64GB DDR4 2666 Kit for MSI Boards

This 64GB kit contains four 16GB DDR4 DIMMs rated at 2666MHz with CL19 timings. It is built as system-specific memory validated for select MSI motherboards including MEG X570 GODLIKE, MEG Z490 GODLIKE and MPG X570 GAMING PRO CARBON WIFI. The unbuffered, non-ECC modules operate at 1.2V and use a 288-pin interface.

Suited for matched four-slot upgrades.

The kit targets users populating four slots with identical modules to maximise dual-channel throughput on the listed platforms. Builders who need ECC support, registered DIMMs, lower latency bins or speeds above 2666MHz should look elsewhere. Systems limited to two DIMM slots or requiring single-rank modules will not benefit from this four-piece configuration.

Four 16GB modules fill half the board's 128GB

The motherboards referenced support up to 128GB across eight sockets, so this kit occupies four slots and leaves four free for future expansion. At 2666MHz CL19 the memory handles typical productivity and gaming workloads within the CPU controller's rated range. Workloads demanding higher bandwidth or tighter timings will hit the kit's fixed speed and latency limits.

Questions about this item

Does my motherboard need four free 288-pin DDR4 slots to install this 64 GB kit?

Yes, the kit contains four 16 GB DIMMs and each occupies one 288-pin DDR4 slot, so four empty slots are required.

If I keep my existing 2666 MHz DDR4 modules, will this kit run at the same speed?

All installed memory runs at the slowest module's speed; mixing with other 2666 MHz DDR4 will keep the system at 2666 MHz.

How can I verify the kit is running at 2666 MHz with CL19 timings after installation?

Enter the BIOS or use a tool such as CPU-Z to confirm the memory reports 2666 MHz and 19-19-19 timings at 1.2 V.
