How to install Xigmatek Dark Knight1283 , the night hawk edition on socket 2011?
The installation guide is not helpful, it does not specify into which category my cpu falls, type 1 or type 2. Do I still need to use the back plate or not? If I do in which position?
I would be very grateful if someone could clarify this for me.
Thank you.
cpu i7 3820 3.60 ghz, x4 mobo Asus p9x79 pro, psu Coolemaster 1200w gold pro.
