i currently run my old Trident Z Kit and it defaults to a 2T Command Rate.
on Ryzen it defaults to 1T and it is completely stable on Alder Lake as well.

Can someone explain me what the difference between 1N, N:1 and Real 1N is? all three are working and have no influence on performance or latency in AIDA.

I would be interested to know too, after putting my ADL setup together.
 
Its not new. These extras have been around since at least 10th gen. What does it do? No idea myself. Never found any documentation on it.

N=T which means it would translate to 1:T and Real 1T.
 
On my system, 1N is 1T, 2N is 2T, and Auto defaults to 2T. I don't know what the other options mean.
