the terms Dual Rank are often confused with those such as Dual Channel and Single Channel, which is instead a very different technology and requires the installation of two identical modules; and also with the terms Dual Side and Single Side, which indicate the positioning of the chips on the single RAM module.

We can say with certainty that in Desktop and especially Gaming, Dual Rank technology does not lead to any advantage, but rather can penalize performance in that, it reduces the speed of operation of the modules as they strain the single channel bus of the memory controller.

You should also be aware that if the laptop is still under warranty, if opened not by ASUS authorized personnel, you will lose it. And also if you replace hardware not from Asustek.

Consider that in ROGs (I don't know if also in TUFs) there is anti-tamper technology or something like that, so even trivial tampering can render the PC unusable.
That's why ASUS recommends that any repair or service be done directly by ASUS authorized centers.

So investigate thoroughly before doing anything, otherwise you might as well throw the laptop away.

As long as it's two sticks and the same capacity for both kits, single rank will be slightly better. You will notice very little, if any difference however, so if the dual rank is much cheaper, you should get that.
