I know that sounds funny, but when I removed it from my MOBO, the bootup process will take up to 15 minutes longer when normally it takes around 1 to 2 minutes.
Yes it does sound strange. I don't really understand your question. You say when you removed it from your mobo the bootup process will take up to 15 minutes longer when normally it takes around 1 - 2 minutes. So have you already removed it?
