I have met, two days ago bought an Inruida 2666 memory, is using Inruida 2400 sliver. Why not buy 2400, because of cheap $10, 2666 plant is 2400 the frequency of use in anyway. Two plug up together, crazy restart, the debug lights, restart, cycling. Solution is simple, I was bought out of time due to AMD generation msi motherboard B350 mortars, at that time the BIOS version is low, a lot of memory chips are not compatible, upgrade the BIOS driver. Then go into the BIOS and set the memory frequency to 2400. As for the upgrade to motherboard brand's official website to check for yourself.
