4gb showing 3gb ram usable in windows 7 32bit os

[Dilshad Dillu]

i have radeon hd7770 ddr5 1gb dedicated
and 1277 mb shared system memory

i have 4gb ram but only 3gb is usable

will i get full use of 4gb when i change to windows 8.1 64 bit

 

[i7Baby]

No. 3gb usable means 1gb is being used.

Are you seeing this in the BIOS, or inside Windows?

 

[the great randini]

yes. but you will have to do a fresh install you cannot upgrade from windows 8 32 bit to 8.1 64 bit

[Dilshad Dillu]

inside system

yes. but you will have to do a fresh install you cannot upgrade from windows 8 32 bit to 8.1 64 bit

will that solve this problem

As i7 baby said, no.

The only way to be able to use all of your RAM would be to get a better graphics card. Or you could maybe just get more RAM. What motherboard and RAM do you have?

Does upgrading to Windows 8/8.1 increase the amount of graphics memory?

This is dependent on your hardware and software configuration which is set by your computer manufacturer. Check with your computer manufacturer for the actual maximum graphics memory supported by your computer with Windows 8/8.1.


How is graphics memory allocated in Windows 8/8.1*?


The Microsoft Windows 8/8.1 operating system adds improved support for graphics, simplifying graphics, memory configuration, and management. As part of this new graphics memory management, the Intel® HD Graphics Driver leaves more of the graphics memory sizing to Windows 8/8.1.





Can I control how much graphics memory is used by a single application?

No. The amount of graphics memory in use is dynamically allocated to balance the needs of the operating system and all running applications.

This is a desktop PC right? With a dedicated GPU? So I'm not sure what that 1227 'shared' memory is since you are not using on-board graphics.

But I do believe that on a 32 bit Windows OS the "usable" RAM is the term (since Vista sp 1) what is left over after memory mapped I/O - in other words when you hit the three gig limit (3 +/-) on a 32 Windows will tell you what your installed RAM is and what your usable RAM is, so in that case you do end up with 4 gig usable after switching to a 64 bit os but only if your motherboard supports it.

 

[i7Baby]

I bet its got integrated graphics using the extra ram.

 

[bignastyid]

Installing a 64-bit os will make all 4gb usable.

 

[i7Baby]

Won't help if its allocated to integrated graphics.

Can you please give us a list of all your parts?

 

[the great randini]

if you install a 32 bit os, you are limited to 3.25 gb of ram. if you install a 64 bit windows 8(non pro) you can have all 4 gb usable.

I don't get this. Are you using both the graphics card and the onboard graphics? Is that even possible?

I'm pretty sure it is possible and that would explain it. So try disabling on-board GPU.
