A PC I'm turning into a server has a sticker saying 512 MB DDR SDRAM. But if you check under the Control Panel->System, it shows a RAM of 448 MB.

SDRAM is a faster version of DRAM, is that their way of saying the 448 MB operates at 512MB?

Thanks.

I am not too sure what that is, but when I am in Linux, it says I have about 900 MB ram when I have 1024, so would be nice for an understanding of this.

Does it have shared video memory?

Check your bios, missing 64MB seems like an suspicious amount. If you added a video card you could disable the shared video and gain the memory back.

yea check the video memory, if the graphics card is on board then thats where she went to (memory)

You need to install a highmem enabled kernel. ;)

Didnt think about that. How old is your kernel? Although, I thought HighMem was for systems over 1GB. Otherwise you want it off?

It's for 1GB and up, including 1GB, otherwise 960MB is the most it will recognize.

Yes, it's 64 MB of shared video indeed. I can't manually disable/enable it, however. Would have to take out the whole apparatus.

Thanks for your help.

You won't be able to remove it - it will be part of the motherboard.
As PC's won't boot without a video card then your two choices are:

1. Leave it as it is.
2. Disable the onboard video and install a £15 PCI or AGP video card that has it's own memory and doesn't use the onboard pool at all.
