The “2E1 memory size error” usually means your system detected a mismatch or change in installed RAM. Before jumping into fixes, could you share a few quick details?

  • Did you recently upgrade, remove, or swap memory modules?

  • How much RAM is currently installed, and what does BIOS or Windows show?

  • Is the error appearing before Windows loads, or only after login?

  • Have you checked if the RAM sticks are fully seated and match your system’s specs?

Or you can go through:

  • Checking BIOS settings and clearing CMOS

  • Running memory diagnostics like MemTest86 

  • Reviewing HP’s official guide on Diagnostic Startup Errors 

  • Exploring community fixes like HP Thread where users resolved similar issues
