Can I get ECC RAM in a consumer laptop?

No. ECC memory is almost exclusively in servers, desktop workstations, and a few “mobile workstations” like Lenovo ThinkPad P series or Dell Precision — not consumer laptops. Consumer models like ThinkPad X1 Carbon, Dell XPS, MacBook Pro, Surface, and Asus ZenBook use standard non-ECC RAM because the CPU chipsets and BIOS don’t support it. Even AMD Ryzen PRO chips technically support ECC on some boards, but no consumer laptop ships that way. If you need ECC, get a desktop or server.
