4Gb RAM, 32bit Vista
After installing SP1 on Vista, the system properties report that I have 4Gb
RAM installed, which is true. However it seems that from the Task Manager, it only can handle up to 3 Gb RAM. So is the other 1Gb wasted? Or is it actually in use for other invisible purposes? |

4Gb RAM, 32bit Vista
It is pretty much wasted. It is a limitation of the 32 bit operating
systems. It can only address 4 GB of memory. This includes the BIOS, I/O, video memory, etc. So, you have ~3.2 GB of RAM left in that address space. In order to fully use the 4 GB of RAM, you'd need to upgrade to a 64 bit OS. -- Dustin Harper http://www.vistarip.com | Vista Resource & Information Page "LL" wrote in message ...

4Gb RAM, 32bit Vista
Nothing has changed except what is reported on the system properties page.
It now reports installed ram. Type winver in Start/Search and you will see the memory available for user programs just as before. "LL" wrote in message ...

4Gb RAM, 32bit Vista
i feel confused seeing different answers. some say it is wasted, some say it
is not. i heard that the rest of RAM is used for hardware addressing purposes. can someone clearify on that please? HP says my notebook can run 64bit vista, but i dont think i'd spend time to change it fearing that something may not work.

NO it is NOT wasted, yes it is available, just not reported. |

NO it is NOT wasted, yes it is available, just not reported. Install Vista 64 only if you have a requirement to use MORE than 4gb. Not all hardware devices have 64bit drivers written for them.

4Gb RAM, 32bit Vista
The "shortfall" is reserved by the BIOS for things like memory-mapped IO for
your video card and such. It is in use but not by user programs. There are two of you using the computer, you and the computer. Don't worry about it.

Yes, it is wasted.
The 32-bit versions of Windows Vista limit the total available memory to 3.12 G. http://support.microsoft.com/kb/929605 ------- *Report back, please* [When responding to posts, please include the post(s) you are replying to so that others may learn and benefit from the issue] [How to ask a question] http://support.microsoft.com/kb/555375 "Colin Barnhorst" wrote in message ...

4Gb RAM, 32bit Vista
There is no 3.12GB limit. Reread the KB and you will see that this is only
an example that the author uses. The memory available for user programs varies widely according to the BIOS as set by the mobo manufacturer. It can range from as little as 2GB to 3.5GB (it ranges from 2.5GB to 3.5GB across my own systems). Throw a pair of SLI video cards with lots of video ram into your box and you will see the differences. "Bob" wrote in message . .. Yes, it is wasted.
