my motherboard(GIGABYTE GA-AM1M-S2H) has two single channel RAM slots.can i use 22GB memory modules, means each memory module in each slot or i have to use only 14GB 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 22GB vs 14GB won’t make any difference. If buying new memory, 1*4GB is better choice because bigger sticks always have more use later.
