so to make a LONG story short, my daughter ended up with my son's old gaming computer. but, one of the memory sticks went bad. its ddr3 memory, but without opening it up and removing the one good stick, i really do not know exactly what is in it. so i have a question. i am thinking about buying a pair of of these https://www.newegg.com/corsair-16gb-240-pin-ddr3-sdram/p/N82E16820233365 because i THINK that is whats in it now. it has a asus z97a motherboard, which is dual channel. so if i install the new ones in the primary channel, and whats in it now, will it work if they are not exactly the same (speed, etc.)? i read someplace that the modules should actually be even made from the same batch, which is not going to happen now since the original system was built years ago.
