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. |

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?

3700X @4GHz: 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 |

And why would you run your RAM @ CL 26?  |

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?

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) |

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. |

What are the voltages? Not sure about your timimngs |

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.

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.

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. |

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

I know, man, I'm still mining cryptonight_r with CPU, 1500 h/s not to shabby. |

Seems stable for now after almost 24h, with a little bump of memory voltage. Tomorrow it'll start to shine with RandomX  |

How much you pulling power from the wall? No, as I said, do not mine with 3900x with stock cooler. I'm using a Cooler Master MasterLiquid 240, mid range AIO, but it keeps the CPU 20ºc cooler than stock cooler. It's pulling 520W at the wall, CPU + 2 Vegas 56 mining cryptonight_r. Power supply is an Enermax Triathlor 1000W. |

Power supply is an Enermax Triathlor 1000W. yeah that is the bargain cooler. i have four cpus. i use the corsair 280 aio it is the best i use the fractal 240 aio i. use the evga 240 aio i use the cooler master aio 240 the corsair is the coolest the other three are about the same. and the cooler master is 30 dollars less. |

Agree. However it was cheap and it's a world of difference from the stock cooler. |

I'd get the cooler master aio if I were to build a Ryzen rig. I'm pretty sure the things aren't durable though. I just don't trust AIOs. But then again, if they manage to do their thing for two years it'd still be acceptable.
