It's a symptom of worrying too much. I just checked my desktop, and it has 81MB reserved. Hardware reserved in large sizes (like a DIMM's size) can be a clue that you have bad RAM or an unsupported RAM configuration, but 100MB is fine.

That I don't know. It's consistently higher than just a few MBs on newer systems, though. Probably UEFI's fault .

39 MB here.

39 MB here.

My old systems, all BIOS, had 1MB, 2MB, and 8MB. Maybe not related, but that's where that suspicion comes from.

 

[dave_the_nerd]

Reading around, it looks like that may be in reserve by a PCI-E device or something. Some people were saying sound cards, but *shrug*

76 MB here, Win 7 SP1 - When I hover over it says for BIOS and some drivers for other perphs. This is on an Asus G73JH ATI 5870 Card no integrated graphics

but it's the symptom of some dysfunction, and I want to know what the problem is.

No it is not, various device drivers will reserve system memory for their operation. Got sound card?
RAMMap utility should tell you if it is "driver locked", then that's what it us.

I don't think hardware reserved is driver locked. Anything hardware reserved is going to be BIOS/firmware reserved.

Should have bought 32.119GB of Ram instead

 

[shabby]

I think 119MB is excessive, but I would have accepted it as 'normal' had it not been for the fact that the amount changed.

Just wait until you check the capacity of your ssd's and figure out they're not actually 256gb/512gb...

589 MB Hardware Reserved here at work. Haven't a clue what it's reserved for but the machine is working great so I really don't even care.

I have 8GB, 144MB reserved, and I don't even care. I don't see the big deal.

Windows 8.1 64-bit I should note.

32-bit OS, most likely.
