Windows 7: Help, Win 7 is stealing my memory!

Help, Win 7 is stealing my memory!

Hardware reserved memory 1089 MB

The resource monitor states that that 1089 MB of memory is reserved for use by the Bios and some other peripherals. I can't imagine why the Bios needs 1GB of memory so that I only get to use 3 out of the 4 GB that I have installed. Is there any way that I can take this memory back?

Thanks,
Bill

PS: Sorry for the duplicate post in the General Discussions.

Possibly bios update. It could be helpful to fill in your system specs so members could discuss with accuracy, in relation to your hardware. Thanks.

Specs are a good suggestion, thanks.

Write down any settings you want to keep and take it from there. After flash, adjust settings back to how they are.

It's not particularly a good idea to flash an overclocked board.

Going by the updates seen, I think it will fix what the thread is about.

Ok, and how do I put the BIOS back to default? I'm a BIOS noob sorry ;-(

Inside bios there will be an option on main screen to "Load Optimized Defaults."

You didn't say, but are you running the 32-bit version of Windows? If so, this is a known characteristic of 32-bit addressing. The memory isn't really being used by the BIOS, but the address space is reserved by the BIOS and controllers, so the memory is not available for use.

You can find lots of explanations of this on the web. For example, here.

On my P5W DH Deluxe, there is a BIOS setting for 64-bit compatibility mode. With Windows XP 32-bit, I found I had about 200MB more memory available by disabling that option. I haven't tried that with Windows 7 yet.

EDIT: I just checked my BIOS settings and the option in my Asus mobo BIOS is called the "memory remap feature." That option is supposed to be enabled for 64-bit OS. When enabled, a 32-bit Windows gets 3 GB of the 4 GB installed on my system, while a 64-bit Win 7 gets all 4 GB. When disabled, Windows 32-bit gets 3.2 GB of memory. The system resource monitor reports the missing 1 GB (or 800 MB) as "hardware reserved."

No it is not a characteristic of 32bit addressing. 32bit can access 4 GB. Hardware reservation is part of the x86 architecture not 32bit addressing scheme. The same thing can and does exist in x64 as well. It all depends on the chipset of the motherboard.

Memory remapping is what you need.
