Microsoft claims that it is not their fault and is instead a limitation of the 32 bit architecture. This is a known limitation of the Windows Vista and 7 x86 editions. Depending upon your hardware, anywhere between 2.75 GB and 3.5 GB of RAM will be available to the OS.īut, what if you have more than 4 GB RAM? Even on a system with 32 GB RAM, 32 bit editions of Windows will display less than 4 GB of memory. Due to this Windows always displays less than 4 GB RAM as the amount of usable memory. For example, PCI Express support will reserve 256-768 MB depending upon the graphics adapter. So, where did the remaining memory go?Īs it turns out, chunks of your RAM are reserved for various purposes and are not available to the operating system. If you have 4GB or more RAM then you are probably familiar with the following screen.Ĭomputer Properties displayed installed memory as 4GB but at the same time stated that only 3 GB is usable. Although I paid for 4GB of RAM, Windows refused to use more than 3GB. But, I had another minor niggle to figure out. Couple of months back, I had blogged about a peculiar Windows 7 issue which could cause a BSOD (Blue Screen of Death) if the system had 4GB (or more) RAM.
