I tried to boot using 256 mb seperately and it works. both channel work using 256 mb separately. Even, when I use only one of them then in bios it shows 256 and computer starts up.

I dont understand exactly where is the problem.

do you use an onboard graphics card ?

If BIOS post shows 512mb and XP shows 256mb, and you have on-board graphics, the graphics chip will be using the memory...that`s my opinion...

Thanks for ur prompt reply.
In my motherboard there is built-in video card i,e
Embedded ATI Rage XL with 8MB memory
this is the basic specification--------

Manufacturer: Dell computer corporation
Model: Poweredge 700
OS: Microsoft Windows XP Professional
CPU/Ram: 2.793 GHz / 255 MB
Video Card: RAGE XL PCI
Sound Card: SB 5.1 (on-board)

So, do you have any alternate idea in configuration relating to ram channel or something like that?

um...when you start your system, on the initial screen, do you see a statement "Dual Channel Memory" ?

built-in-video card? you have igp. there is option in bios that reduce or increase shared memory used by igp. In your case it seems the igp uses 256mb when both ram installed.

yup...that was my assumption...because of his confusion, he told us that he is using built-in card...and it was my bad too --- I should have checked the video card...

@kwese, thanks 4 ur response

when I use only 256 mb in one channel then it shows 256 mb in both bios and windows. In this case why this video card don't share any memory? the built-in video card has its own 8mb memory.

When 256mb of ram installed only 8mb is used by igp. Install both sticks and start.Go to desktop and right click the empty area context menu appear and click properties,display properties window will appear click settings tab then click advanced button small window will appear click adapter tab look for 'memory size' that used by igp.

I have already SOLVED the problem !!!!!!!!!!!

I tried to check each option of bios again using F1 key for help. There is a "OS Installation Mode" option whose value should be either ON or OFF(default). When I pressed F1 key it gave me a message like this.........

"if this is on then total memory will be 256mb of total memory for operating system but if this is off(default) then operating system will get the full system memory.

It was "ON", so operating system memory was 256mb only whereas total memory is 512mb. But, now I set that "OFF" and OS have total 512mb as shown in my compouter properties.

Thanks for your co-operation.

...a thing is NOT strange if it is unknown to you...

Actually, OS Installation Mode is common for Dell Machines. This limits the amount of available memory to 256 MB because some operating systems will not complete installation with more than 2 GB of system memory.

No problem kuwese...just in future, please investigate a little before you say "strange" and so...actually, OS Installation Mode is very often on the dell machines...I am assuming you`re not using Dell Machine, so you haven`t heard about "OS Installation Mode"...forgiven...enjoy now...
