9800X3D RAM buying guide by Buildzoid

Very newbie question here.

I can see clearly that we don't want 4 sticks. BUT I read a post way back in the thread that said we wanted ram in single stacks, so do we now want them in different channels? Mainboards have 4 ram slots, 2 in each channel, so if I get a set of two 16gb sticks, do I put them in the same channel on the mainboard or not? Used to be we needed to do that.

And I'm struggling to find 6000 cl30 ram that is expo rather than xmp. :(

SO do I want the expo one or this one that looks faster?

I don’t entirely know what you’re asking but I’ll see if I can answer the question with my understanding of it.

You do put them in the same channel, typically channel 2 and 4 (the 2nd and last slot going away from your motherboard but consult your manual).

Yeah so my mainboard has 4 slots, two black two grey and they aren't next to each other, and so I assumed my pair of sticks went in either grey or black, not one in each.

Most consumer motherboards have two memory channels which they name channel: A and channel B.

The slots which are next to each other (regardless of colour) are usually ONE channel, which is why you typically use slot 2 and 4 for a 2 stick configuration.

If your 2x RAM sticks are together in the board, then you're almost certainly doing it wrong, since there should be an empty slot between them.

The reason we call it dual channel is because you can put 1x stick in channel A and 1x stick in channel B and then get both channels operating together (dual channel).

The use four slots is still dual channel, you're just using a 2 dimm per channel config (known as 2DPC), which is usually best avoided due to added load on the CPU's memory controller.

Read the manual.
Thank you so much..
My confusion came from the use of language earlier in the thread.

I've always known ram to be installed in pairs in slots that are grouped by channel but the post refered to rank and one guy saying single rank i'm unsure why my head decided this may be suggesting something to do with slot configuration rather than different types on dimm. :( I thought installed in single rank was one dimm in each channel hence single rank rather than 2 dimms to the channel: dual rank. But yes I should have read closer.)

Thank you! So I was right, we want one stick in each channel, so the board runs in dual rank (ie uses both channels and the bandwidth isn't shared with a second dimm in each channel?)

I get it. So yes, my main board has slot 1 and 3 one colour and slot 2 and 4 another colour while slot 1 and 2 are labelled channel A and 3 and 4 channel B. My memory is in the slot 2 and 4 grey slots. So I'm good. thanks
 
But any advice on those two different dimms I suggested? I was trying to find some 6000 cl30 but the corsair memory (my prefered go to for ram) didn't have a 6000 cl30 that is marked as EXPO. :(

Yeah, that's right.

Though, dual channel is the correct term for this, since ranks are usually on the RAM sticks themselves.

Physically, dual rank is usually seen in a stick that has memory chips on both sides, while single rank sticks have memory chips only on one side.

Oh yes, ok this is why I got so confused. Thanks
 
should probably add that if someone does buy a 6400 kit, it will likely in the bios default to asynchronous mode instead of synchronous mode and not be 1:1 and be slower than 6000 anyway. this can be manually changed but for those not familiar with ddr5 and am5 it might be something thats missed
