Resuming Windows 7 from Hibernate after a RAM change?

You will get an error message from the Windows Resume Loader on restart. You will get this nasty warning:

Your system's memory configuration has changed since it entered hibernation. If you proceed, the data needed to resume from hibernation will be lost. To preserve this data, turn off the system power, restore the orginal memory configuration and reboot the system. Otherwise, press to delete restoration data and proceed to system boot menu.

If you continue without restoring the original memory configuration, you will get roughly the same affect as if you had removed power suddenly rather than hibernating.

I know that this is an old thread, but for that ones that are curious: Windows was hibernating and i disconnected it from mains voltage. I added two RAM modules that are exactly the same as the ones I have already built in. After connecting my PC to the power and booting Windows 10, it decided to restart completely. From there on I had a fresh rebooted system with 32 GB of ram.

I hope I got the answer people like me are asking themselves.
