following:
Channel 1: DDR3_P0_A0, DDR3_P0_A1 (For pimary CPU)
DDR3_P1_D0, DDR3_P1_D1 (For secondary CPU)
Channel 2: DDR3_P0_B0, DDR3_P0_B1(For pimary CPU)
DDR3_P1_E0, DDR3_P1_E1 (For secondary CPU)
Channel 3: DDR3_P0_C0, DDR3_P0_C1(For pimary CPU)
DDR3_P1_F0, DDR3_P1_F1 (For secondary CPU)
2-4 Installing the Memory
Read the following guidelines before you begin to install the memory:
•
Make sure that the motherboard supports the memory. It is recommended that memory of the
same capacity, brand, speed, and chips be used.
•
Always turn off the computer and unplug the power cord from the power outlet before installing
the memory to prevent hardware damage.
