1155-Pin Socket Overview
2.3 CPU Installation
In order to provide the LGA 1155 CPU sock-
ets more protection and make the instal-
lation process easier, ASRock has added
a new protection cover on top of the load
plate to replace the former PnP caps that
were under the load plate. For the installa-
tion of Intel
®
1155-Pin CPUs with the new
protection cover, please follow the steps
below.
Before you insert the 1155-Pin CPU into the socket, please check if the
CPU surface is unclean or if there are any bent pins in the socket. Do
not force to insert the CPU into the socket if above situation is found.
Otherwise, the CPU will be seriously damaged.
Step 1. Open the socket:
Step 1-1. Disengage the lever by pressing it
down and sliding it out of the hook.
You do not have to remove the pro-
tection cover.
Step 1-2. Keep the lever positioned at about
135 degrees in order to flip up the
load plate.
Step 2. Insert the 1155-Pin CPU:
Step 2-1. Hold the CPU by the edge which is
marked with a black line.
Step 2-2. Orient the CPU with the IHS (Inte-
grated Heat Sink) up. Locate Pin1
and the two orientation key notches.
