Maximum RAM - do I listen to dmidecode or the manufacturer?

I have a nice laptop - 32 GB of RAM, M2 (SATA) and 2.5' SSD (also SATA) - dual boot, Fedora 33 & Windows 2019 Server. I ran dmidecode and found a Maximum Capacity of 64GB - but the manufacturer (ASUS) says 32GB is the max! Now, I know that dmidecode isn't perfect , but I want to hear from those who have upgraded their RAM based on dmidecode despite the manufacturer's recommendations? Quote from link above: > Beware that DMI data have proven to be too unreliable to be blindly > trusted. Dmidecode does not scan your hardware, it only reports what > the BIOS told it to. I also found this , which doesn't inspire confidence, where it says: > Aniruddh yes the H300's only support 32gb ram max (officially) its not > the cpu support in this case its the mobo limited/locked support all > bios are locked so unless its a modded bios (which i strongly dont > recommend doing neither its allowed to discuss anything about it in > this community ) probably it wont support so until someone buys 32gb > sodimms and test them theres no way to know if its will support or not > and i doubt anyone would take such a risk on a such high priced ram > without having sure if it would really work or not but anyway of you > are willing to go for it also why would u need 64gb 32 its already too > much no one will ever use them in full and its not having 64gb that > would make the laptop faster in some rare cases too much unused ram > could also cause some bottleneck and decrease the performance but good > luck :) So, it appears even if the mobo specs **allow** a certain amount of RAM, the manufacturer may or may not have reduced this capacity from within the BIOS? Have I grasped the picture - am I taking a big chance going by dmidecode or should I persevere? Any references/URLs, tips - anything appreciated!
