2.3 Installation of Memory Modules (DIMM). ASROCK 870iCafe, 870iCafe R2.0

This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install identical (the same brand, speed, size and chiptype) DDR3 DIMM pair in the slots of the same color. In other words, you have to install identical DDR3 DIMM pair in Dual Channel A (DDR3_A1 and DDR3_B1;

Blue slots; see p.11 No.7) or identical DDR3 DIMM pair in Dual Channel B

(DDR3_A2 and DDR3_B2; White slots; see p.11 No.8), so that Dual Channel

Memory Technology can be activated. This motherboard also allows you to install four DDR3 DIMMs for dual channel configuration, and please install iden- tical

DDR3 DIMMs in all four slots. You may refer to the Dual Channel Memory

Configuration Table below.

For the configuration (3), please install identical DDR3 DIMMs in all four slots.

1. If you want to install two memory modules, for optimal compatibility and reliability, it is recommended to install them in the slots of the same color. In other words, install them either in the set of blue slots

(DDR3_A1 and DDR3_B1), or in the set of white slots (DDR3_A2 and DDR3_B2).

2. If only one memory module or three memory modules are installed in the DDR3 DIMM slots on this motherboard, it is unable to activate the Dual Channel Memory Technology.

3. If a pair of memory modules is NOT installed in the same Dual

Channel, for example, installing a pair of memory modules in

DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel

Memory Technology .

4. It is not allowed to install a DDR or DDR2 memory module into

DDR3 slot; otherwise, this motherboard and DIMM may be damaged.

5. If you adopt DDR3 1866/1800/1600 memory modules on this motherboard, it is recommended to install them on DDR3_A2 and

DDR3_B2 slots.

Please make sure to disconnect power supply before adding or removing DIMMs or the system components.

Step 1. Unlock a DIMM slot by pressing the retaining clips outward.

Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the break on the slot.

The DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.

Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated.
