(and the Asus Q170T)

I’ve picked up a Lenovo Yoga 370 because (amongst other features) it has a removable / upgradable RAM slot (yes, two slots would have been even better :)). You can find various sources (including ChatGPT) claiming it to be 16GB, however, if we look up the processor for this particular model on the Intel website, we’ll see that it supports up to 32GB. And indeed, here is the laptop, happily passing memtest86+ with a 32GB module (specifically this one):

In the same vein, Asus claims a maximum of 2x16GB for their Q170T, however the Intel website says 64GB should work with the i5 processor that’s in the machine, and indeed, here is a machine with 64GB happily passing memtest86+:

The lesson is: processor specs are more relevant than (in)official documentation when determining the maximum supported RAM size.
