Joined today just so I can put this little problem out there and see if someone can shed some light on it as it has baffled me somewhat.
I have 4gb of RAM installed on Windows 7 32-bit , I know that 32-bit won`t allow me to use all of it, but I believe I should be able to access at least 3.5Gb.
Anyway, I can only use 2.5Gb as alot is Hardware Reserved ( 1538Mb to be precise ), I could accept that fact if the following didn`t happen - this is what is confusing me no end.
When I remove one strip of RAM ( I have 2x 2gb ) , the memory obviously drops to 2gb, BUT, the hardware reserved memory also drops - to 2MB!!
As soon as I put the other strip back in and go back to 4Gb I`m suddenly hit with the 1538Mb Hardware reserved again.
To try diagnosing things, I removed my PCI graphics card and used the onboard VGA. The hardware reserved memory then dropped to 750Mb, so I came to the conclusion that the graphics card is taking 750mb. But ( this is what confuses me ) , when I only have 2gb installed the hardware reserved is 2mb , so nothing is been reserved for the graphics card in this case, and whatever is using the other 750mb doesn`t take it either!
I need the VGA card installed as I use two monitors at work and the card is dual head.
Can anyone tell me why the hardware reserved memory rockets up to 1538Mb when I have the 4gb installed, yet is only 2mb with 2gb installed?
Surely if the VGA card ( and whatever else ) needs the 1538mb then it would still try and take it with only 2gb installed.
I really need to try and free up this reserved memory as I need to run Virtual PCs on my machine and have a few other programs open at once. It`s just bugging me like hell now!
