Windows XP does now see all memory

Hello,
I have windows xp 32 bit and ATI RADEON HD 3870 x2 but there is a problem, windows XP does not see all memory just 512 MB and also when I start any game it crashes after few minutes. Is there any chance to get all memory in windows XP??

gothard, your 3870X2 is a video card with two GPU's. Each GPU has a dedicated 512mb of memory. By crossfiring the GPU's your connecting only the GPU's it in no way doubles the memory to 1gb.

Now also the 3870X2 is one power hungry video card, what is the output of your power supply? When you start running a game thats when the card really puts a load on the power supply. I would expect you will find your PSU is weak.

evongugg try reading the original post; how are you to reseat the mmeory on a video card?

That would be fine if he were clear that its video memory hes looking at, but he doesnt say that, he just says memory.

Wow this is yet again an example of a poster not giving any sort of useful information.

I assume now he is talking about memory not showing up ont he video cards control panel where it says "video memory" with all the debate about windows xp seeing over 4gb in windows xp I think that has us all confused what he's asking.

Poster you need to put relevent information.

What type of video card, motherboard, os, and mainboard memory do you have?

Where are you looking exactly where your not seeing the memory, and what exactly do you expect to see there that you don't?

As far as crashing goes, please put more of a description of the problem up, I am going to assume the amount of memory not showing up, has nothing to do with crashing.

Make sure you get the latest and greatest drivers for your mb and your video card for the appropriate companies website, that may help fix any issues. Also, another thing to look at would be swaping out the card with a known good to eliminate that. Go to BB or CC or wherever get a basic card to test with, if that does not crash your system, most likely it is your current video card and it should be rma'd.

Just my two cents.
Thanks

Maybe because it's not a problem...Crossfiring or SLI'ing 2 videocards together does not combine the memory buffers of both GPU's, and the same goes for the 3870X2, because it's just 2 GPU's Crossfired on a single PCB.

Damn, when I saw the title "Windows XP does now see all memory", I thought it meant service pack 3 would let you see a full 4 gigs of memory. Impossible I know, but one can dream.

Oops, I meant 32-bit XP! Waiting until I finally transition to Vista to do 64-bit.

There is a difference between seeing and allocating. 32bit XP/Vista can see all 4GB of physical memory. It just cannot allocate it. My Vista shows 4GB but can only use 3.5GB.

i think it would be stupid to assume the poster has a 3870x2 and only 512mb of system ram...

I with Stoner133 on this one. though im voting driver issue.
