However on a different PC Windows Vista Business with 2 Gb Ram no such. Read this article first, though. Question: Hi, I found your website today during a search on Vista. My question is will 3. Vista Ultimate support more RAM? IE 4 or 3? Answer: I thought this was a slam- dunk, but it turns out to be a damn good question! The short answer is, the practical upper limit is usually about 3. GB of RAM. The long answer takes some explanation… Here’s the official answer from Microsoft: 3. Windows Vista Home Basic, Home Premium, Business, Enterprise, and Ultimate: 4. GB3. 2- bit Windows Vista Starter: 1. GB6. 4- bit versions of Windows Vista Home Basic: 8. GB6. 4- bit versions of Windows Vista Home Premium: 1. GB6. 4- bit versions of Windows Vista Business, Enterprise, and Ultimate: 1. GBSo I search around a little to find some real- world experiences for people with 4. GB installed: This paper from HP helps explain it–the platform can theoretically support the full 4. GB, but your hardware is going to allocate some of the address space (not the physical RAM) to the PCI bus, the video adapter memory address space, and other resources. OSs need to use part of the full 4. GB address space to address these resources, subtracting from the maximum memory you have available to the OS and applications: The PCI memory addresses starting down from 4 GB are used for things like the BIOS, IO cards, networking, PCI hubs, bus bridges, PCI- Express, and video/graphics cards. The BIOS takes up about 5. KB starting from the very top address. Then each of the other items mentioned are allocated address ranges below the BIOS range. The largest block of addresses is allocated for today’s high performance graphics cards which need addresses for at least the amount of memory on the graphics card. The net result is that a high performance x. MB to more than 1 GB for the PCI memory address range before any RAM (physical user memory) addresses are allocated. So, if your video adapter has 5. MB of RAM (like mine does), your maximum memory is going to at most be 3. GB, because Vista has to use 5. MB of that address space to address your video memory. It’ll actually be lower than the 3. GB because there are other hardware resources that need address space, too. So, it never hurts to fill your computer with 4. GB of RAM–you’ll definitely get the max, but you won’t be able to address it all. You probably won’t be able to address much more than 3. GB, and you might not be able to address more than 2. GB. The paper also mentions something interesting about 6. Basically, depending on the hardware, you might be limited to 4. GB of RAM even if you install 6. Windows Vista: Windows XP Professional x. Edition uses 6. 4- bit addressing enabling virtually the entire amount of installed RAM to be made available on computers that have large address infrastructures (where the entire system has more than 4 GB addressing capabilities via the processor, chipset, physical memory capacity, etc). The HP xw. 43. 00, xw. Workstations have the required infrastructures and even the PCI memory address range is recovered by re- mapping it above the top of physical memory. Thanks for the great question. If you’re using 4. GB of RAM with 3. Vista, add a comment and let us know about your experiences. Update 4/9/0. 7: To address the lively Linux- vs- Windows debate in the comments, it seems wildly irrelevant. First, it’s still true that any 3. OS needs to use part of the 4. GB address space to address resources. However, you’re right that Physical Address Extension (PAE) can be used to address more than 4. GB from 3. 2- bit OSs–this is true of some Linux distributions and many 3. Windows OSs. Here’s the catch: applications have to be written specifically to take advantage of PAE, and the only applications that do that are very specialized tools or server applications like SQL Server, which don’t typically require that much RAM when running on a desktop OS. So, PAE won’t make your Photoshop or video editing app any faster, and it isn’t nearly as useful as it sounds. While 6. 4- bit Windows Vista isn’t perfect, it will give you access to your full address space, and you’re bound to have far fewer application compatibility problems (and get more out of your memory) than you would with 3. Linux and PAE. Oh, and take a break from stressing about OS limitations, and read something funny.
