Idryss Posted June 21, 2009 Share Posted June 21, 2009 I just bought some RAM for my laptop, I upgraded it from 2GB to 4GB, so I installed the lateste 64 bits build out there to see the difference. But I see no difference with a 32bits build. I mean, my system only recognize 3GB (In computer, properties, it shows 4GB installed, 3 useable). I don't understand? What do I have to do in order for my Windows to use the 4GB? Link to comment Share on other sites More sharing options...
Sethos Posted June 21, 2009 Share Posted June 21, 2009 You need to install 64 Bit in order to have all 4GB usable, it's a 32 Bit limitation. Link to comment Share on other sites More sharing options...

Sethos Posted June 21, 2009 Share Posted June 21, 2009 Oh I'm sorry, not sure how I failed to read that part :laugh: Try and look through your bios, find the Memory Remap Feature and disable / enable it ( Depending on the current setting ), see what happens. Not sure if that has any bearing under a 64 Bit OS. Link to comment Share on other sites More sharing options...
Idryss Posted June 21, 2009 Author Share Posted June 21, 2009 Another thing which has been bothering me since I upgraded my RAM is that when I start Windows, I get the old Vista style bootloader, instead of Windows 7's one. Any clue? Link to comment Share on other sites More sharing options...
salamanca Posted June 21, 2009 Share Posted June 21, 2009 might be a limitation of your chipset Link to comment Share on other sites More sharing options...
Idryss Posted June 21, 2009 Author Share Posted June 21, 2009 I went in the BIOS, it says I only have 3072MB of RAM installed... I checked Sony's website to find anything to upgrade it, I found it but I will refuse to install -_- Link to comment Share on other sites More sharing options...

SoapyHamHocks Member Posted June 21, 2009 Member Share Posted June 21, 2009 What chipset do you have? Like salamanca said you might be limited by your chipset. Link to comment Share on other sites More sharing options...
Eric Veteran Posted June 21, 2009 Veteran Share Posted June 21, 2009 Does your video card use system ram? ^this... If you have a video chipset like the Intel GMA series and some mobile ATI/Nvidia chips the memory then some (or all) of its memory is taken from system memory.

usman767 Posted June 21, 2009 Share Posted June 21, 2009 Even if the video card takes some amount of RAM, BIOS should be able to tell what amount of ACTUAL RAM is installed in the system more like a chipset problem i think.... Link to comment Share on other sites More sharing options...
jjrambo Posted June 21, 2009 Share Posted June 21, 2009 (edited) x64 edition of Windows 7 is broken. There are so many computers including brand new ones where Vista 7 can't propertly detect all available memory. It is freaking joke. Vista x64 Edition detects it propertly. It has nothing to do with chipset and video card installed. It's just amazing how people are trying to find problems with 10+ things and at the same time not pointing to real problem in Windows 7.

Idryss Posted June 21, 2009 Author Share Posted June 21, 2009 So, according to CPUZ, I have an Intel i945PM chipset. Link to comment Share on other sites More sharing options...
DrDrrae Posted June 21, 2009 Share Posted June 21, 2009 According to Intel's website, that chipset only supports a maximum of 4GiB of memory. Now, this includes memory on the video card and some other set aside for various other parts in the system which, in your case, leaves 3 GiB left for RAM.

DrDrrae Posted June 21, 2009 Share Posted June 21, 2009 Updating the BIOS will have no effect on it. The chipset supports a maximum of 4GiB of RAM and that's it. No amount of software will change the hardware. Link to comment Share on other sites More sharing options...
Idryss Posted June 21, 2009 Author Share Posted June 21, 2009 So, basically, I wasted my money in that 1 extra gigabit of RAM? Running Windows x64 is useless then? Link to comment Share on other sites More sharing options...
jjrambo Posted June 21, 2009 Share Posted June 21, 2009 So, basically, I wasted my money in that 1 extra gigabit of RAM?Running Windows x64 is useless then? No you did not. Go back to Windows XP x64 or Windows Vista x64 Edition and all 4gb will be detected correctly. Link to comment Share on other sites More sharing options...
Idryss Posted June 21, 2009 Author Share Posted June 21, 2009 I'll try to install Vista x64 as soon as I get my DVD back. I'll see if there's a change. Link to comment Share on other sites More sharing options...
