3200 C14 and 3600 C16 run about the same for performance on Zen+ and Zen 2. So far most of the tweaking I have seen shows similar synthetic scores with the two at stock, but the 3200 C14 Samsung B die's have a bit more headroom for OCing if you lower the CAS latency.
I'd leave though at the XMP/DOCP profile settings until the new Ram Calculator comes out later this week.

For my tests, with actual loads that I give this computer, my current 3600 settings are a 5-12% faster.
What is worth noting though is that for some reason, if I manually set 3200MHz the IF will be 1:1 at 1600MHz and so will the UCLK, so 1:1:1. BUT! If I only change to DDR-3600, IF will change to a 1:2 and this will also affect the UCLK, ending with 1800:900:900 for the MCLK:FCLK:UCLK. I have to manually set FCLK to 1800MHz in order to keep 1:1:1 (and it's much better performance wise, MUCH better!!)
Mmm, interesting!

I am assuming that's Zen2 since you are ensuring your infinity fabric speed is the same. I'm looking forward to testing this out too once my 3900x gets here. For the 2700x I have I know it's not any real difference, all within MoE in synthetics, but I was highly curious if it rang true still with Zen 2 or if frequency trumps latency with the IF. Looks like you are saying it does. Once I get it in I'll run several synthetics on both to test out. Hopefully, by the time it arrives there will be a new stable AGESA and bios from Asus. Hopefully I'll get the same results as you, although it doesn't help me since I already bought the expensive RAM, it will help everyone else as 3600 C16 is cheaper than 3200 C14, but its all dropping like rocks right now anyway.

What does it imply if it is daisy chain or not?
These are Corsair Vengeance RGB Pro, 3200Mhz C14, 4x 8GB. I bought them prior to knowing Ryzen was best at 3600MHz though, I probably would've gone for the 3600MHz C16 model instead (although I proved myself to have made the right decision!)
What I did was just try DOCP and since it didn't work, I wrote down all values that it changed (you see them prior to exiting) and set them manually.
It booted perfectly fine and passed Prime95 for 3h, so decided to go and directly try the 3600 C16 model timings (I looked them up online), which were 16-18-18-36 I think. It booted up, and again, Prime95 stable. I left it there.
Then one day I was reading an article which compared scaling of the Ryzen with memory, and their best result at 3600MHz was 16-16-16-34 I think, so I just tried those in BIOS and it booted, and was Prime95 stable. Sooo... I don't know, I might be able to go even further, but I don't think I'll try. This was pure luck I think. Also I've kept the 1.35V, haven't gone any further.
And as for your other question, all other timings are Auto, yes. When you go into the timmings submenu, I think it's 16-16-16-16-34 (there's an extra 16 I think), all the rest at Auto. What really surprised me is that it automatically sets 1T instead of 2T... I was expecting 2T even at 3200Mhz, but I'm getting 3600 16-16-16-34 at 1T... Again, these might be gold memory or... just a standard Corsair kit for all I know.

Check in Boot order list, you should see it there at least.
