Yes, that's right an question of Ram.
Having an issue with my installed Ram. I have 4gb installed, checked etc and even my bios and Cpuiz says i have 4 and cpuiz records them as all working correctly but i am only using 2.75gb apparently. This is what shows up in my properties and also in a programme called fresh Ram.
Now, is there any programme that lets you limit or turn on and off the amount of Ram you use as i for the life of me can't figure it out and the old girl is struggling enough without getting memory loss....
Ran the memory checker from microsoft and that reports no errors.
Puzzling.

32Bit Windows XP can use 4Gb but can only 'see' somewhere between 2.5 and 3.5Gb of ram.
The reason is a very technical, but basically the memory on your graphics card has to also be mapped into this 4Gb. Imagine that the Ram installed in the system is added from the bottom (So from 0Gb) and stuff like video ram, network card cache and other buffers are mapped from the top. (So from 4Gb Downwards)
Eventually they meet in the middle, and video ram etc have to take priority.
Clear as mud?
ETA: Windows Vista/7 32Bit are also the same, but Microsoft fudged it so it lies and displays the full amount installed even though you can't use it all!

got win7 pro 64 bit and ubuntu 10.04 also 64 bit
never understood posers who got high spec machines and then installed low spec OS onto it
what's the point ?
True, but a lot of software still uses 32 bit. Almost all 64 bits also run in 32 bit mode for software. Can be a bit of a nightmare on app serversnever understood posers who got high spec machines and then installed low spec OS onto it
what's the point ?
Well, thank you all very much for your help, it saves me spending ages trying to figure out what is wrong! I suppose having two graphics cards albeit with only 256mb memory just adds to it's confusion.
So, what should i be getting next because the machine i am looking at from Mesh with lots of upgrades has 16gig of Ram and two ATI 2 gig graphics cards and windows 7. Is there any point, will i be able to use it all if needed?

That must be some beastie from Mesh. Just make sure windows 7 is 64 bit. Any software that needs 32 bit will work just fine.
Yes, it's a moddified XGS I7 GTS but you could add another 2 grands worth of optionals on top, upto 24gig of Ram and the beasty Intel® Core™ i7 980X Extreme Edition Processor (3.33GHz,12MB Cache) which i think has 6 cores, and a 256 gig solid state drive.I am sticking with the I7 960 quadcore.
It is a beast and quite exensive but the one i have now is 8 years old now and suffering
A 32 bit machine can only address 0 to 2 to the power of 32−1, or, to put it another way, 4,294,967,295 bytes. It has to allow for all sorts of things, video cards for instance are generally 512MB and up these days, so that's 512MB that needs to be addressed and cannot be used for anything else.
A 64 bit machine should be able to address 0 to 2 to the power of 64−1, or, to put it another way, 18,446,744,073,709,551,615 bytes. That's more than 18 exabytes. In practice though, most processors have an artificial limit imposed, for example, the AMD64 architecture currently has a 52 bit limit on physical memory and only supports a 48-bit virtual address space. Either way Suddenly a 512MB card is an irrelevance.
I've had a socket 1366 motherboard with an intel i7 and 24GB for about 18 months, it's plenty fast.

Wow, no idea XP only recognises 3gb or in my case it states 2.75.
So does that mean it only makes use of 2.75 or only displays?
Getting this from right clicking on my computer.
the difference between 3GB and 2.75GB is probably due to the video card sharing the memory. ie taking 256MB for its useWow, no idea XP only recognises 3gb or in my case it states 2.75.

Slightly off topic but I had 64bit XP installed and it kept crashing. Is this common?
If you didn't check the hardware compatability list for your PC and its components, then yes....can you post the stop code on the blue screen of death (assuming thats what you mean by crashing)

Except that 32 bit games will invariably run slower than if they were running on a 32 bit system of equivalent CPU / RAM.Video editing, rendering, large database manipulations or strong number crunching will benefit assuming they are 64 bit apps. Video may even benefit if 32 bit in some cases.
Until all games are coded in 64 bit this is a waste of money (if gaming is your intended use for this machine).
I ran XP64 bit for a while, but found it to be the same or slower in some cases compared to 64bit.
You will also need to find a 64bit A/V program, as a 32 bit one will slow the system as I found myself.
