Windows 7: What's reserving 51MB of memory?

What's reserving 51MB of memory?

Hello All,

I noticed in Resource Monitor that 51MB of my memory is 'Hardware Reserved' and I'm just wondering what's reserving this.



I don't have the IGD enabled so that's not using any. I know the BIOS usually reserves a few MB but I'm not sure why it's 51MB, maybe modern day BIOSs/UEFI systems reserve more than they used to?

My MB is a GA-Z87-HD3 and could it be something to do with Intel's Management Engine?

This isn't really an issue but rather curiosity as to what's reserving it.

Thanks.

Modern day hardware reserves actually use less memory then before. Especially uefi.

When you hover over it, it states that drivers are also a factor. Perhaps you might have some heft drivers installed. People with dedicated graphics card have beefier drivers, which could be an explanation. It could also be a lot of old flash drive drivers or other items, etc. Look in device manager and uninstall old devices found under other show all items.

Your usage is normal.

Thanks Andrew for the reply.

Yes, just had a look and it also says drivers are reserving some of the memory as well. Don't quite understand this, I just assumed it was the BIOS that was taking up space.

Hovering over the 'In Use' section and that also states it used by drivers, so I'm a bit unclear on the difference.

EDIT - Just read it again and it says "Reserved by drivers for some peripherals". This makes more sense, it's not actually reserved for the driver but rather provides memory to a device that doesn't. I guess it will work a bit like shared graphics memory.
