2E1 memory size error. How eliminate the errorcode?

[Shema-glitch]

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

Das gleiche Problem hatte ich auch.
Entfernen Sie vom Mainboard die Batterie und resetten Sie den Mainboard-Jumper.
Danach muss nur noch die Uhrzeit aktualisiert werden.
