GTX 285 1GB With 32bit OS Help?

[dax40]

Hi, I am currently having some problems with an OS to use, I have tried Windows 7 but my wireless adapter does not have the suitable drivers for 7. I installed Windows Xp 64Bit last night but xp 64bit has got a bug with a Razor Deathadder mouse where it jumps.

So i am now looking at installing Windows Xp 32Bit with 4GB RAM and a Geforce GTX285 1GB.

Would this run fine or would it struggle with memory usage?

Hope someone can point me in the right direction.

Thanks

It should run perfectly fine on 32bit Xp.
Just bear in mind that you will lose a gig of ram due to 32bit limitations.

yep running a 260 here with 4GB and all is good. Windows shows 3.25GB of RAM which is more than enough for anything currently. Have tried the Windows 7 rc myself but annoyed at several show stopping bugs.

32bit windows can only support 4gb of ram.
Basic 64bit OS's can support 8gb and ultimate OS's can support up to 16gb.

But thats 4gb for both video ram and general with 32bit.

Although im not 100% sure but windows might steal 1gb regardless and keep it for system process's only. Dont quote me on this though.

Resulting in 2gb for general and 1gb for your video card.

32bit is a 4gb limit, note that 1gb grahpics mememory wont take off 1gb of system ram. It will take off a little, but there are plenty of people running 2gb cards on xp fine (and still over 3gb ram left).

I'm pretty sure its 4gb total, ive read an article on it not s long ago.
Someone else care to add?

As far as I know if you have a 1Gb card the system will take 1Gb from your RAM as a 32 bit OS can only address 4Gb total!

So that will leave you 3Gb minus all the other stuff.

So you may only have 2.75Gb usable.

I think

Wow, there's so much misinformation surrounding this topic, it's unbelieveable.

The amount of memory on your graphics card does not directly affect the 4gb limit in XP 32bit.

There will be some memory allocated for the graphics card, but it does not correspond to the ram on the card.

I'm using XP 32bit and I can still see and use 3.25gb of memory after moving from 512mb graphics card to a 1024mb card.

Wrong, it's Premium which is limited to 16gig. Ultimate/Business can use 128gig.

XP64bit has the same 128GB limitation as Windows Server 2003, and Vista Ultimate edition.

For what its worth windows 32bit, and most windows 32bit applications also have a 2GB limit, in general any 1 application wont use more than 2gb of ram on a 32bit windows platform.

Basically windows (32bit and 64bit) divide memory into two blocks, Kernel space (for drivers, and most of the OS, but also for some low level applications), and user space (for applications).

The /3gb option for 32bit windows extends the userspace to 3gb, but that only works for applications which are programmed to make use of it (microsoft SQL server is one of a very few examples). As a general rule of thumb unless you multitask more ram on a 32bit os has diminishing returns as you pass 2.5gb.

On a 64bit OS 32bit apps can get upto 4gb of userspace without the need for a hack, while 64bit apps can have as much as they want. Subject to how much ram is installed, and which version of windows is installed.

Exactly!

Various devices in a typical computer require memory-mapped access. This is known as memory-mapped I/O (MMIO). For the MMIO space to be available to 32-bit operating systems, the MMIO space must reside within the first 4 GB of address space.

For example, if you have a video card that has 256 MB of onboard memory, that memory must be mapped within the first 4 GB of address space. If 4 GB of system memory is already installed, part of that address space must be reserved by the graphics memory mapping. Graphics memory mapping overwrites a part of the system memory. These conditions reduce the total amount of system memory that is available to the operating system.

The reduction in available system memory depends on the devices that are installed in the computer. However, to avoid potential driver compatibility issues, the 32-bit versions of Windows Vista limit the total available memory to 3.12 GB. See the "More information" section for information about potential driver compatibility issues.

If a computer has many installed devices, the available memory may be reduced to 3 GB or less. However, the maximum memory available in 32-bit versions of Windows Vista is typically 3.12 GB.
