Dual channel memory

[Steven2996]

i want to ask something, if the cpu that said on the web (ryzen/intel) only support 2 channel memory will it run quad channel memory?
and how much memory that cpu could support? it is depends on the motherboard or depends to the cpu?
thanks, best regards

Usually depends on the motherboard.

It will run with 4 Sticks of memory, but not Quad Channel, obviously.

But with 4 Sticks you loose maximum frequency, wich means that DDR4-3200 might not be possible and, with 4 Sticks, you might be limited to DDR4-2800 or something around there.

 

But those sticks might be specially slected for X99, maybe X299, so they might not run as well on Ryzen.

so if the motherboard had (in case 4 channel and max might be 64 gigs)
all the ram should be detected as 64 gigs, but with some comprimise in speed right?

If the Motherboard has 4 DIMM Sockets and is AM4 or LGA115x, then yes, with 4 Sticks of Memory its still Dual Channel and you loose max. Memory frequency.
