Ok so for every one who doesn't know what their doing this is a combo of what I've learnt and all of it is either official AMD recommendations or stock settings for components.
AMD recommend you start with 1.1v on the SOC and VDDG if you are overclocking your ram.
If you have the 8 pack ram then the 3200MHz stuff will do 3600MHz easy.
No need to up the dram voltage keep it at 1.35v just put your timings in 16 16 16 16 36 and set the FCLK to 1800MHz.
You should be good to go.

Oh... with mine it won't boot at this speed so I have to go up the speed slowly. Start at 2400 , reboot 2800, etc etc until you get to target 3600MHz.
Just to add to your wisdom, If you set the ram in ryzen master and save then reboot it works straight away, you can then enter the bios to see it set it for you there.
You can overclock manually in ryzen master of the cores without having to restart, i found it useful to set 4.3ghz for example then apply it, run the cpuz bench for idea of performance then increase to 4.35ghz and add v and bench again.
When i was hapy at 4.4ghz i would go into the bios and set the vcore LLC and the Vrms LLc to high performance mode. go back to ryzen master and lower the voltage until it crashed (about 1.3v for 4.4ghz for me) then you can set it all great,.
The ram and turn on manual OC, restart, ryzen master - manual OC to the volts you found with your core OC
You can also after doing the ram and setting manual OC in ryzen master and restarting, go into the bios and set an all core in there with LLC and vcore all at the same time.
I'm close to scrapping custom loop and just getting a nice AIO and one of those EVGA hybrid kits for the GPU.
I'm going to update to a 3950x when it comes out so I need to take it apart again. *sniff.
Maybe have a look in the members market sometime (like right now) maybe theres a 2080ti evga AIO hybrid kit... you never know
Had a bit more of tinker with my 3700X. They do run hot if you overclock. 4.1 all core in CB R20 hitting about 75C. 4916 score though which isn't bad. I wonder if improvements could be made with my EK Phoenix to improve the cooling?
With the EK phoenix, if you can open the cpu block and make sure the fins run vertically inside you will get gains for a 3xxxx chip, i did this with an ek supremacy block and reduced the temps by 10.c on
