Ram Memory Problem

[CuFy1991]

Hi I have a problem with ram memory.
I have bought Ram 4GB DDr2, I also had 2 Rams with 1gb So before that I had only 2 GB Ram.
After Insalling 4GB Ram it showed me 6GB (1,99 GB Usable).
So my windows was 32 bit and i changed it to 64 bit, but it also show the same thing.
I tried to change rams into different slots but it shows this before windows starts:

"2211-Memory not configured correctly for proper MEBx executions.
Make sure there is a memory module in the black DIMM socket

Make sure there is a memory module in the black DIMM1 socket and that it is properly seated. Take it out and put it back in.

What is your motherboard model?

Try one stick of RAM at a time - one of them may be bad.
