I have here one Intel DP55KG Mainboard, which I want to build it in my new PC.
Always when I want to turn on the System I can see the Error-Code "21" on the MB-Display.
The CPU is a i5-560, the Memory is a G.Skill Ripjaws X, and the VGA is a nVidia 210GTX...
I hope somebody can help me and my PC. Thx
I did a search and read a little about it in an Intel board. Code 21 is for initializing a chipset component. First boot with just one stick of ram to see if it is still there. If it isn't then boot with the other stick. One user solved it with a new Bios battery despite not having the low battery message. Some had bad ram slots. Most had to just RMA the board.
