4GB memory ram installed 3.80 usable, why?

[Muddabir]

Earlier I had windows 7 B memory ram 4GM was useable but not when I switched to windows 8 it said 4GB installed 3.80Useable , I tried setting maximum memory option In msnconfig boot option but it took me to256MB and took a while to fix things .

Attached contain all files .

Thanks

The difference between installed and useable is for "hardware reserved."

I noticed you're missing the power management ACPI driver from Toshiba:

Not Available ACPI\QCI0701\2&DABA3FF&1 The drivers for this device are not installed.

 

[Muddabir]

please check driver is installed

Please check its installed seems like wrong info being collected by tool

The info is from msinfo32. You can type that in the Start menu, press Enter, then look at Problem Devices in Components section and see for yourself.

The one missing a driver is either in System devices section of the device manager or it's hidden. To see hidden ones >>> View | Show hidden devices.

power management ACPI driver from Toshiba

Should do the trick.

 

[Muddabir]

Windows does it itself

Pleasecheck and confirm if installed properly the driver name only wont help figure out how to save time search for driver on web and do it within seconds using windows help
By selecting computer and then instead of selecting drive search option below done the trick.
But it still 3.80GB useable

Ya man. The driver has nothing to do with 3.8 GB. The different as I said, is due to "hardware reserved" - In plain English, that mainly means your video adapter is using the difference, and possibly other hardware too.

You have no more problem devices so seems that you did install the driver well.

You can type dxdiag in the start menu, press enter, then go to display tab and make a screenshot.

I can tell you that your video adapter has 1.68 GB RAM.

Here u go

Looks like your video adapter is not using system ram because total video memory is the same as msinfo32 shows. (Msinfo32 shows only dedicated video RAM alone. For instance, my video card has 512 MB ram but my whole system uses 760 MB of video RAM in total.)

What you can try is go into your bios settings. If there is a setting for memory hole, enable it. If it is enabled already, disabled it. See how it goes with that change.

 

[Muddabir]

Could u plz guide me how can I go to system bios?

 

[GMan]

No, I can't because all motherboards are completely different. You will have to Google for your motherboard's manual and have a look at it. Or if you have the physical paper manual, it will also tell you in it.

On my systems, I have to keep pressing delete key on the keyboard when the system is booting - but like I said, it's always different.

Usually but not always, pressing F10 saves changes in the bios after you make them.

 

[Muddabir]

Oh Thats F2 in mine

 

[Muddabir]

There were no such settings as memory hole

 

[GMan]

It's not something I would worry about too much. One a system with 4 GB RAM, the difference of .2 GB is in no way going to do anything good or bad at all.

Here is more reading about it if you would like to see: The usable memory may be less than the installed memory on Windows 7-based computers

That being said, you still may be able to find some setting in the bios that does something. But be careful that you don't just go changing things willy nilly. I would Google about any specific setting if you aren't sure and find out what it does, first.

If you have Windows 8 x86 (32 bit) then there is nothing to be done and all is perfect already.

If you have memory remapping in the bios, enable that.

 

[Muddabir]

no memory remapping thing as well have 64-bit os

Most boards use some RAM. Some more, some less. I would not worry about it. I think you are chasing a red herring.

Your using intergrated video. There is nothing wrong and most likely nothing you can do to change. my laptop has an i5 with 8gb of ram but because I'm using the intel HD graphics and not a discrete graphics card. Only 7985MB is avail and not the whole 8gb. Some Bios's let you change the amount of ram dedicated to graphics but its usually on the older motherboards.

 

[jryoo]

aren't you using 32 bit windows?
