1.3.2 was only popular to keep the higher 200W on the 2080. I personally do not care since I run the AGA. I ran my M15x from 2009 (I forget, I think two sticks banged together) -> 680M (2014) -> 980M(2018) and even got Occulus Rift running on it (such great memories Xmas work week VR stuff w coworkers). So that's 17 years on only two Alienware laptops....not bad. Area 51m "upgradability" was a total knife in the back. Zero drop-in....not even 2080 Super but the 2080 worked for me through Cyperpunk, BG3 & Alyx so I didn't suffer. Only recently with 2025+ titles did I dust off the AGA and throw in a 5080 to continue being fine.
I heard from Amir that 1.7.3 has more forgiving RAM speed settings vs. 1.9.3
