my motherboard(GIGABYTE GA-AM1M-S2H) has two single channel RAM slots.can i use 2*2GB memory modules, means each memory module in each slot or i have to use only 1*4GB memory module in one slot.what is the difference between dual channel RAM & Single channel RAM,is it is RAM spcefic or Motherboard specific.please explain me.
Dual channel ram doubles memory bandwidth. For dual channel you need: - At least 2 sticks of RAM - Motherboard + CPU that supports dual channel There is no spesifically "dual channel memory sticks" as any 2 sticks at same size are OK. Dual channel memory sticks is just marketing BS. As for your system, it supports only single channel. So 2*2GB vs 1*4GB won't make any difference. If buying new memory, 1*4GB is better choice because bigger sticks always have more use later.
