Sorry guys I was unclear. I have the 24pin plus the 4 pin connected. I am now receiving 2 short beeps on POST but no video. I cant seem to find a beep code for the mobo this is what i am using. http://www.newegg.com/Product/Product.aspx?Item=N82E16813131795
2 short beeps is usually a memory problem.
Try reinstalling sticks one at a time and booting.
Are you sure you have them in the correct slots. Some motherboards are very picky about which slots are populated.
