My computer wont read my ram

i just went out and got a 1GB stick of DDR400 ram. i currently have 2x
512 stick of DDR400 in my computer. i stalled the RAM and have check
the RAM under control pannel/system and it still shows im only running
1gb. i scanned my comp with CPU-Z and it says im running 2gb RAM

im not sure which one is right. i no there is a way to check it
through the bios but im not sure how to do it.

also just so i dident screw up installing it i just leave the 512 in
the first 2 slots then put the 1gb into the next slot along???

just a thought...
I would check your mobo manual to confirm this is correct.
You may have to switch them around...ie put the 1gb in the
first slot.

Depends on the motherboard. It might require they be installed in
pairs to complete a "bank".

How much memory is reported by the BIOS on the POST summary screen
(i.e., after you power up but before Windows loads)?

That's usually not the case with DIMMs. It was with the older SIMMs.
Usually one DIMM completes a bank.

I would try reseating the RAM, or as was suggested, try them in different
slots. Also, make sure the motherboard can handle a 1GB DIMM. The Manual
should show a chart for valid memory configuration.

You can also go into the BIOS Setup to see what is shown for total RAM.

Knowing the motherboard model (which is obviously critical
information) would help a lot but the OP didn't mention it.

It's also possible the OP got suckered into buying "high-density"
modules because of their cheaper price (often by half) but which won't
work in his motherboard.

Also possible is that the OP will need to change the memory settings
in BIOS, probably starting with the default setting (Auto). The OP
never mentioned the specs for his old memory and the specs for the new
memory. I suspect they don't match.
