I've noticed a strange phenomenon with my Lenovo V110-15IKB after I put in another 4 GB into the only slot available:
Though the BIOS recognizes the full 8GB, macOS 10.12 (and also 10.13/High Sierra) does not and does not start at all. But when I start Linux or Windows both seem to accept both.
To have startup macOS I have to manually register the RAM in Clovers Config.plist.
Another strange effect is with Memtest86:
The utility only sees the soldered 4GB but not the new module, though it obviously recognizes the full 8192MB.
