Is it time to upgrade? 3800x or a 3900x....or wait for the 3950x lol

What I am saying is the BEST speed for ram is to match IF 3733mhz. Never said it's required and in Ryen3k, you can decouple the memory speed but it will degrade your performance. Anything beyond 3733 will be a diminishing return scenario in real world performance.

I know what you’re saying. What I’m saying is IF will be matched below 3733. IF is only officially rated at 3200 so 3200 memory will run IF at 3200 so you don’t need 3733 and you don’t need to decouple. In my case I can’t even get IF to 3733 without raising voltage and I’m not alone.

Now I’m not necessarily disagreeing with your memory suggestion. I’m just saying running below 3733 will not decouple the IF it will still be 1:1 and that you may not even be able to get to 3733 at default settings, so I wouldn’t be terribly concerned if you don’t get 3733 memory.
 
Something to shoot for. That's all. So even though the chipset is not rated for it.. its a good place to start - if can swing it.

So you are saying my RAM that already runs at 3800 would be fine for the 3950x? That is cool.

Im my x3900 experience, a 3800 kit with the tightest timings you can get and a fabric clock of 1900 is the sweet spot.

I could use some better timing RAM but I do run the fabric at 1900 as well. Currently it is at stock 18-22-22-42.
 
Just a note to the thread as I thought it would have been countered already. TDP does not = power usage. It unfortunately isn't as simple as that, as well as varying from different manufactures. If we are under the assumption a 3700X uses %50 less power then a 3800X because of a TDP rating we would be incorrect.
Nice vid by GN on the whole topic.
