ASRock H61M-GE [19/58] Installation of memory modules dimm

2.5 Installation of Memory Modules (DIMM)

This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM

slots, and supports Dual Channel Memory Technology. For dual channel con-

guration, you always need to install identical (the same brand, speed, size

and chip-type) 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.12 No.4), so that Dual Channel Memory Tech-

nology can be activated. This motherboard also allows you to install four DDR3

DIMMs for dual channel configuration, and please install identical DDR3

DIMMs in all four slots. You may refer to the Dual Channel Memory Congura-

tion Table below.

For the conguration (2), 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 blue slots

(DDR3_A1 and DDR3_B1).

2. 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.

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

DDR3 slot; otherwise, this motherboard and DIMM may be dam-

aged.

4. Some DDR3 1GB double-sided DIMMs with 16 chips may not work

on this motherboard. It is not recommended to install them on this

motherboard.

5. If you install four single-sided DIMMs on this motherboard, they will

run at DDR3 1066 only.

6. Due to chipset limitation, if you plan to install three or four memory

modules on this motherboard, please install only single-sided

memory modules.

7. This motherboard supports two double-sided or four single-sided

DIMMs. Therefore, if you install four DDR3 DIMMs, you can only

adopt four single-sided DIMMs.
