I have two os(xp and windows 7). I have 965 express intel grafic card max256mb but it shows max251mb on windows 7(run dxdiag I see it) It shows max256 on windows xp. why doesn't it show max256mb on windows 7 ? where does it's 5mb go?
Doesn't really matter dude, its onboard, its not an Nvidia or ATI card. The less ram your onboard gpu uses the better!! For basic pc use (no gaming) like 32 to 128mb is more than enough.
Ty. But it uses only windows 7 or (vista maybe). Then windows xp is better than windows7 in a way. And other old my pc is same but it's not onboard.(Nvidia geforce2 mxmx400 64mb but it shows 63.5mb on windows7. it shows 64mb on xp. run dxdiag.)
Did you ever look Desktop Aero in Windows XP and its previous versions? I think NO. If you see in Vista and 7, then you will see Aero and 7 also have very very dynamic menus and magnificient colors as compared to all other Windows. So that's why Windows 7 use high graphic card with its maximum memory. Another example is that if you don't use compatible graphic card in Windows 7, then Aero function doesn't get ON and Windows doesn't take graphic memory too. So we can say that Aero takes graphic memory in Windows 7. I hope this will help you.
A system with 4GB of RAM and Windows 7 32 bit installed will report as having 3.5GB RAM in XP, which is the amount usable, while Windows 7 will report 4GB, because people complained about "missing RAM", even though 3.5GB is the amount usable.
