Hi there...I have put 2 memory sticks to a gigabyte z490m with an intel i5 10400f of tottaly 16 gb and 3200. I have already inside a memory stick of 8gb and 2666...can i sync the first 2 running for 3200 and the last for 2666 or they have all to run under 2666??? Is it better to take out the 8gb 2666 stick and continue with 16gb ?? Thanx in advance...
