The Acer Nitro 5 -AN515-51 can support ddr4 2666mhz ?

Somebody knows wat will happen if you use one ram of 2400mhz and another of 2666mhz at the same time?

When the 2400MHz RAM stick is paired with the 2666MHz RAM stick, both of the RAMs will run in dual channel configuration @2400MHz.

For example, to pair 2 rams, you need the same cas latency, timings and recommended voltage. Which means you cannot mix a ddr3 and a DDR4 RAM. Assuming both are DDR4, even then it is not guaranteed. If the mother board is picky or if the latency is off by even a little, it won't work or worse, you will be greeted by the blue screen of death.

In the event that it does work the motherboard will underclock the higher ram. So no, you will not get better speed than 2400MHz. In fact there is not even a complete guarantee that it will work.
