Nopes, it isn't.
Reboots after a couple hours mining monero.
Let's try a bit more voltage.

Wow. Thanks a lot.
I did it and now RandomX benchmark hits 13300 H/s. Me happy.
Now let's see if it's stable 24/7.

tRFC=631 is very very bad timing. tRFC is crucial for high hashrate, most good results I've seen use tRFC=300 or less. Just use Ryzen DRAM calculator with fast preset to get better timings and set _all_ timings it shows you.
I used a tighter timings profile in the bios (MSI X570-A Pro) and result is the same.
~11k, 24 threads.
Timings are:
Dram frequency 1800 Mhz
FSB:DRAM 5:54
CL 14
tRCD 16
tRP 16
tRAS 36
tRC 84
tRFC 631
CR 1T
DIMM voltage is 1,472
I though DDR4-3600 @ 14-16-16-36 timings was pretty fast RAM, but apparently I'm wrong.

I set my Corsair Vengeance to 3633 Mhz @ 16-17-17-34-50 timings.
Not great performance, though. 11000 H/s.
What am I doing wrong?

What are the voltages?
Not sure about your timimngs
Watercool your 3900x.
I went from 85ºc with stock cooler with lots of fans and open case to ~64ºc with watercooling, plus + 166 Mhz boost for free. No overclocking.
I wouldn't be confortable runnig a CPU @ 85ºc 24/7. It will fail, sooner or later.

Seems like a option, i wont be running it over 80c in any case. I rather then reduce the clock peed and voltages.
And why would you run your RAM @ CL 26? 
that`s the Q to asus-support and to bios-makers from asia (why the default is so ugly)

Ok, that makes sense.
I still haven't tuned memory timings.
I have 2x8GB Corsair Vengeance RGB 16GB DDR4-3466MHz CL16 (CMR16GX4M2C3466C16)
Memory runs fine @ 3466 spec and higher (but it starts to relax timings).
Anyone knows what memory dies brand are in this?

DDR4 3600MHz auto (CL26) - 6.8Khs
DDR4 3600MHz tuned (CL16) - 8.4Khs
+23.5% - because of tuned RAM
UPD 28/11/2019: decr. trfc from 345 to 278 gives +150h/s, so it pushes 8550h/s so far

On another topic, why is system RAM speeds so important for RamdomX?
Isn't it supposed to run on L2/L3 cache, and that's why it performs so well on Ryzen's?
Because it uses 2 GB dataset in system RAM. Isn't it supposed to run on L2/L3 cache, and that's why it performs so well on Ryzen's?

It will be used for mining also.
My plan of this setup is.
MSI B450 Tomahawk max motherboard
2x3600mhz ram
2xRX5700
Ryzen 9 3900x
So not to waste other hardware i can do dual mining for example with GPU i mine ETH.
Also can use it as gaming and rendering bench.
In such a way you are getting not a rig but a serious worstation that you can use in any way: for games, for mining, for work. If you will use it only for mining ROI would be really huge. Its nice decision. My plan of this setup is.

Thanks for taking the time to put together this information, it really helps when deciding if its worth using these to mine or just get one for a kick-butt editing system. Memory seems to have a big impact on RandomX so I will be interested to see how it impacts the hash rate. It makes me wonder what kind of impact the new Threadrippers with quad channel memory will have on mining performance compared to dual channel.
Thank you for feedback3rd generation Treadripper should be out soon, havent really followed they release date. Price range seems attractive.
It would be great if we would get some dual CPU boards for them.
At the end of it it will come to price per hash 🤞

1xRX5700 for image
nice GPU "for image" anything over 80c will destroy your cpu in a few months
If you have several CPU, you can exchange them under warranty. I think you can get the full price for several months of use.It always amazes me that some people would run the CPU/GPU hot rather
than run the fans hard. Fans are cheaper to replace, but I haven't had one fail
yet in 5 years, Just clean them regularly.
I think the same. I have now 4 GPUs with 120mm fans that looks bad but works normally than run the fans hard. Fans are cheaper to replace, but I haven't had one fail
yet in 5 years, Just clean them regularly.

as long as you dont go higher than manufacture's maximum rpm then is okay,than run the fans hard. Fans are cheaper to replace, but I haven't had one fail
yet in 5 years, Just clean them regularly.
A GPU a fan failure under warantee should be covered regardless. A failure
of a 3rd party CPU cooler could be blamed on the mobo for overdriving it.
I have my fan curves set for 80% @ 70C rising to 100% @ 80C. The cooler algos
(and cooler weather) don't run the fans as hard.
