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?

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

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?

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?

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.

Very cool, I just left it running on a 4 polaris machine.
Anyone knows of good mem timings to use with AMDmemtweak with Elpida and Hynix 4 Gb cards?
ref 30 Thanks alot! Free +1 Mh/s on each card.  I have memory strips made with polaris bios editor some 2 years ago, but REF was 5 on all cards. To set it on command line, the argument should be --REF 30000, right? No that would rather be for Vegas  . For Polaris, it’s just “--REF 30”. You can always inspect the current values to get a feeling for the right scale. Thanks. Great, great work. Now I can use TRM only. As as you said, other miners do not report real hashrate. Using it for >12h, despite reporting -2 Mh/s than the miner I was using, calculated hashrate @ the pool went up 4 Mh/s... That said, I'm not getting miner reported hashrate to eth.nanopool.org. How can I turn that on? I believe nanopool only can do reported hashrate with the ethproxy protocol. We typically default to one of the other possible protocols. Try adding "--eth_stratum_mode=ethproxy", I think it will solve it for you. Otherwise, let us know and we'll look into it more closely. Nopes, it says "Pool eth-eu1.nanopool rpc method "eth_getWork" timed out after 69 seconds. Discarding." That's nothing to worry about though, but you're still not seeing any reported hashrates? Please confirm and I'll look into it. No. It briefly reported (black line), but then it stopped reporting again.  |

Of course it's not "needed". Even with air cooling it's running within spec.
It depends on the algo, most algos favourable to CPUs run relatively cool because they often stall waiting for memory. If you want to see how hot it can get try sha256d. Of course. But here I'm making a before and after comparison. Mining Monero running 21 threads Stock cooler (Wraith Prism) - 84-85ºC @ 3.99 Ghz Masterliquid 240 - 62-63ºC @ 4.166 Ghz. |

No need water cooling for 3900x. I used one Thermalright 140 with two fans, and one with stock cooler but with a $10 fan pointing at the rig. Both of them are around 12k at around 70c. I set the cpus running at 4G around 1.2v.
Of course it's not "needed". Even with air cooling it's running within spec. But I definitely feel more confortable with 62-63ºC with all cores @ 4.14/4.166 Ghz. And this with a water cooler that's cheaper than the high-end air coolers. |

I actually have more agressive timings (--RAS 28 --RCDRD 12 --RCDWR 5 --RC 44 --RP 12 --RRDS 3 --RRDL 3 --REF 15600 --RFC 246 --FAW 14)
but memory is only good up to 940 Mhz. I really don't want to risk the cards flashing a Vega 64 bios.
I can barely get 39 MH/s on one and 42 MH/s on another.
But they both do 2050-2080 H/s mining monero.

I mine with 4 vega56 and they make 44mgh each and the whole rig burns 650 watts . I think vega56 is pretty efficient in eth , when you play with it.
What clockspeeds / memory timings? |
|
|
|
Yes, me too. I get half my house warm in winter with mining  But I was not thinking about ETH. Maybe some CN coin not ASIC dominated? |

https://whattomine.com/coins/151-eth-ethash?utf8=%E2%9C%93&hr=30.0&p=140.0&fee=2&cost=0.1&hcost=0.0&commit=CalculateIf you trolls call eth polaris mining "profitable" per day per card $0.04 then you need to recheck your brains, mental health issues, go to a clinic as soon as possible. Even a beggar in a corner make 1000 times more than that per day without saying a word. There is just one reason you trolls must be happy with such misery, you probably all live in venezuela and even that misery of money is worth in there. Yeah, beggars die in venezuela, flourish in developed nations. There was a news saying beggars are earning per month 4 times more than the monthly minimum wage which where I live is $1500 usd, I guess mining got to a such deplorable state that it shows it cant get any worse, do not be surprise if mining in few months rise 100 times, $4 per day per card because the way things are, only the people in venezuela might be happy with such misery. 95% of eth hashrate likely from hidden asics, no way in hell these many cards are earning $0.04 per card per day is doing the job, no way in hell and the g3 from bitmain was supposed to be doing 3gh/s, heard there was even a g4 producing an amazing 15gh/s, no wonder why eth price crashed to hehell and hashrate is very much intact and rising, the only ones earning money here as always are asics. You must be a fun person at parties... Some people mine just for the fun of it, to tweak the system, the cards, the mining software... I turn off the heating in the rooms that have miners, so basically electricity is "free" You really don't need to be this agressive, just look at what you wrote. What's the point? |

Yes, but Vegas aren't nearly as efficient as Polaris cards to mine Eth.
I got ~ 82 Mh/s from my 2 vegas, and ~120 Mh/s from my 4 Polaris.
Not the case with CN-R, as you know it.

As above.
Of course my 2 Vegas were amazing mining Monero, performance in CN is just amazing. I have other rig with 4 Polaris 4 Gb cards mining ETH, still the most profitable coin with Polaris, so that's not a concern for now (maybe when DAG doesn't fit the 4 Gb cards...)
But that will change with monero going RandomX, I would need 8 Vegas to give the same hashrate as my Ryzen 3900x @ 130W...
What are you planing to mine with Vegas after monero fork?
