Hello batch 0 
For those of you (and in other batches as well of course) who are bringing your own RAM to a DIY laptop 12, once you’ve used it for a little while if you don’t mind sharing exactly which model of RAM you’re using and how it’s going so far, that would be awesome for the rest of us who are yet to purchase their RAM. The following thread seems like the right place to do so: Which RAM-modules to use?
It would be especially interesting for memory modules that are not mentioned in the Knowledge Base article about memory modules for the Laptop 12.
Thanks, and enjoy your new laptop!
