AMD Ryzen 9 🖥️ 3900x RandomX mining benchmarks

[Set Ready Go]

It would be intresting with some cooling numbers on the wraith prism . Max fan Speed 2750rpm and Then  if you could flip switch on cooler so that Max 3750rpm (turbo cooling)

Help me here on a most weird problem.

I have a Ryzen 1700 machine, with 16 Gb RAM and 3 Ellesmere cards that refuses to mine RandomX.

It already mined it fine, then XMrig and xmr-stak just exited.
I thought it was a config problem, so I copied the config.json and edited address and walet and it started mining it no problems at all.

Today I rebooted because a card wasn't sending shares, and now I can't mine.



It just exits, sometimes sends one or 2 shares and then exits.

No warning, no nothing.
XMR-stak displays a similar behaviour.

I disabled Windows antivirus, added an exclusion to folder, system is stable, I tested with memtest and prime 95.

I have one more 1700 and a 3900x and it works just fine, no issues.

Mining a CN/R coin like Lethean gives no trouble at all.
It was mining it until now. But I want my 4300 H/s monero hashrate from it.

https://blog.nicehash.com/post/how-to-limit-threads-on-the-cpu
...
NiceHash miner uses two different CPU miners.
XmrStak
XMRig

XMRig
To limit threads when mining with XMRig you have to follow these steps:
Open Benchmark tab
Select your CPU device and XMRig
Look for Extra Launch Parameters text-box and write --threads=N where N is a number of threads you want to use. Example to use 8 threads: --threads=8
...

any using nice hash and limiting threads?

Supposedly you need to turn off  Opcache in bios

Does that go for another name? Can't see that option.

It's a Gigabyte B450M DS3H.

Common options Then AMD CBS/CPU



So i belive its in the M.I.T section.
Then go to Advanced CPU core section
Then Opcache control, Then just disable

[lncm]

I'll try it.

But since yesterday I got it running, don't know why. It has something to do with Ryzen Master being on.
Now, this is a weird behaviour, it's mining without a hiccup 8 treads @ 4300 H/s for 14h now...

And it's definitely something with hardware setting, the other Ryzen 1700 has exact same motherboard and memories, and I did clone its hard drive and booted it on the uncooperating Ryzen Machine. It displayed the same behaviour, exited a couple seconds after it started mining, with same OS, settings and XMRig config that works on the other machine.

yeah all three 3900x are working.


but my threadripper is like fuck you any help would be nice.

OK, I found it and disabled, and it solved the problem.
At least XMRig started fine and didn't exit until now, without the need to launch ryzen master and fiddling with settings.

Thanks!

Np man!  I had this happen to me yesterday but on a ryzen 5 3600.
So i was changing profile in ryzen master, suddenly no  miner program would run, resetted ryzen master and it was ok. So yeah can happen strange things.

i wonder how it is in the taichi x399 board.

i think i did it correctly but i am not at 6000 or 7000 with. my thread ripper 1920x. i am doing 4900-5100

which is better then the 600 i was doing. i used a different option something like cbs/cpu

[marinko9]

Why don't you have any new RandomX miner in your shop yet? How much is some miner with a few AMD Ryzen 9 CPUs and all the other components needed to plug and play a miner and mine something?

I am not sure how profitable is it to mine Monero at all with the current difficulty 101 G.

If it runs, but slow, memory timings should be the problem.

I was getting 10500 with my 3900x, and after following advice here, it's now @ 13500 H/s...

randomX has been a bust so far , i cant see this many cpu farms active , botnets or fpgas , back to square O

[thefix]

I am getting around 4600 h/s on RandomX with a threadripper 1950x with 32 gb of ram at 3200 in a quad channel setup. Looks like faster dual channel memory has a bigger impact than the quad channel setup.

14 threads seems to be the sweet spot

I don't know. My 3 systems hashrate went up 4x with less power.
Network hashrate tripled.

What miner are you using? I guess shouldnt really matter xmrig/xmrstak preety much same hashrate

I dont get how you can get so low hashrate, hmm have you set large pages and that miner allocate it correctly?  so it shows like "JIT 1020/1020" and not "JIT 20/1020"

You should have double hashrate then what you have.

My 12 core TR1920x does 7500 h/s  with 3200 cl 16  and 16gb quad channel memory (4x4)gb  this @ 3,7ghz cpu and 1.15v

So yeah something strange with your setup man, if you have popped in the wrong memory slots eg A1  B1 etc etc ...   Correct placement in your manual.

Also could you link your batch file with cpu affinity / threads.

If you could make a batch file in xmrig folder and do this :

Code:

@echo off
xmrig.exe, -o PoolUrl, -u YourWalletadress.Workername, -t 16, --cpu-affinity 0x55555555, --cpu-priority 5, -l, --log-file=Troubleshooting
pause

I ended up bumping up the large page files to 2048 in linux after reading the results you are getting with a 1920x and I am now getting close to 9000 h/s which is a major bump. I think I may be able to get more from what I am reading from other users by increasing the page file size with quad channel memory. Thanks for the feedback and tips, it helped me almost double my original results

About 600 MH was added to the network...thats like 40k 3900x. I would say half the new hash is from existing systems mining monero since they can, so 10-20k "new" systems in farms is not that much considering 100s of thousands of ASICs on other networks.
