(Note 2) The bridge connector(s) may be needed or not depending on your graphics cards.
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that memory
of the same capacity, brand, speed, and chips be used. For optimum performance, when enabling Dual
Channel mode with two memory modules, we recommend that you install them in the DDR4_A2 and
DDR4_B2 sockets.
1-5 Installing an Expansion Card
Read the following guidelines before you begin to install an expansion card:
• Make sure the motherboard supports the expansion card. Carefully read the manual that came
with your expansion card.
• Always turn off the computer and unplug the power cord from the power outlet before installing an
expansion card to prevent hardware damage.
