PcPartPicker gives me as compatible with my other parts this mobo: H110I-PLUS/CSM or H110I-PLUS-D3/CSM. I have two questions. I guess the D3 means that it takes DDR3 and DDR3L and other one is for DDR4.Right? Second question is.. In my country I cant find this /CSM thing. It only appears the H110I-PLUS and the D3 one. What does this CSM means? Will I have a technical problem? Is it a different Mobo?
