The Curse of Soldered RAM
Summary
A hardware-focused blog post about the trend of soldered RAM in modern laptops, using the Lenovo X1 Carbon as a case study. It recounts RAM failure symptoms, demonstrates Memtest86+ testing showing errors, and discusses memory replacement limitations due to soldered DIMMs. The author explores memory-safety workarounds using Linux kernel memmap, grub parameters, and boot-time configuration, including a grubenv-based fix, and plans to back up data and run file-system checks while awaiting a new device.
