I am tempted to just put 48 in there. The price of RAM scales nicely and it would get me the most from the i5 device. Yet I know it is most likely overkill. I will use this device as main device and for my engineering classes and also some CAD and Matlab on the side. Most of the time it’s tasks will only be running OneNote and Firefox under win11.
I had 32 initially on my 16, but found that having a large number of large PDFs and Google Docs open (writing research papers for my EdD program) caused me to start slowing down. I moved up to 96 and have barely gone over 40 used, so I think 48 is a good target for college work.
I have 48GB waiting for my FW12. It will be overkill, but the price was right and just a bit more expensive then 32GB. So, why not. And prepared for the future now. For memory it is always better to have too much then too less.
I’m going the other direction - putting 8G of DDR4 in it. see if I can make the battery last all day or even longer. Going to run Manjaro with KDE Plasma.
JTrevail is correct. While the processor supports DDR4 or DDR5, the sockets are different, so a particular machine can only use one or the other, and the FW 12 is set up for DDR5.
