    I have a video card, GPU-z says it has 128 MB of RAM. There are four RAM chips, they are Qimonda HYB18T256161BF-20.

    I downloaded the data sheet. It says each chip is 256 Mbits. So I divided that by 8 bits/Byte, that is 32 MBytes. I have 4 of these chips on the video card, that gives me total of 128 MBytes of RAM. Am I doing it right?

    You only have to remember that 1 Mbit = 1/8th MB, 8 Mbit = 1 MB.
