I have Windows 10 32-bit installed on my laptop (HP Pavilion G7) with a single 4 GB stick of RAM. But the system only reports 932 MB of memory. I have tried removing the module and putting it back.

Output of wmic memorychip list full:

BankLabel=BANK 1

DataWidth=64 
Description=Physical Memory 
DeviceLocator=Bottom-Slot 2(under)

This question is different from the marked duplicate because there are 3 out of 4 GB missing!

Your BIOS either does not support, or is not configured to support, a 32-bit OS. Most of the address space below 4GB is reserved for hardware devices that cannot access addresses above 4GB. The BIOS has remapped your memory above the 4GB mark to make room for such hardware mappings.

If your BIOS supports 32-bit OSes, you need to figure out how to enable that support. Usually it's an option called "memory remapping" that you turn OFF. But it could be something else.

If your BIOS doesn't support 32-bit OSes, use a 64-bit OS. I can't find anything that says your laptop supports 32-bit OSes and it wouldn't be a good idea to install one even if it did.

  • If this is correct (as I suspect it is), this is a notably different answer than those given by the question this post was originally marked a duplicate of. – I say Reinstate Monica Jan 19 '18 at 00:48
  • @TwistyImpersonator Yeah, the people who marked it as a duplicate probably didn't actually read it. That's why everyone voted to re-open it. – David Schwartz Jan 19 '18 at 00:59
