I currently have HyperX Fury 8gb (2x4gb) 2666mhz. My mobo has 4 slots. Planning to add 2 more same brand but different speed. The one available at my location is only the 2400mhz. Is it going to be a problem?
Speed and capacity makes more of a difference. Most people recommend using sticks of the same speed and capacity across all ram slots for maximum performance
But the ram will cause problems if they have different timings and voltages
Other Rams On 2666 Mhz Will be Downclocked On 2400 To Work . Its A Risk So I Dont Recommended It
In Some Situations We got Some Crashes Because DownClock On Rams Always Can Not Be Worked And Allowed By Other Vital Parts Of Pc Like Mobo And Cpu
So I Dont Recommend It
