I need some help.  I can't get my Ryzen 3900x to mine monero on RandomX any higher than 9200khs.  I have the following set up...

MSI X470 Max
Ryzen 3900x
2 8gb Consair Vengence 3600mhz CL18 Ram
570 4gb card.
windows 10

I've tried stock CPU settings.

I've done the DRAM calculator... Anytime I enter in the timings from the calculator, the Memory just locks up and doesn't boot up into Windows 10.

I've done simple adjustments like OC the CPU from 3800mhz to 4100mhz.

Just looking for proper set up of timing to make this CPU mine atleast over 11000 khs.

Thanks in advance

Hitting 15kh/s + on 3900x now. Could prob push it to nearly 16kh/s but 15 keeps it under 200 watts at the wall  Cool
Is it with MSR mod? What's your memory setup and CPU speed?

Nice stats, 15 kh/s really nice performance on 3900x

It gave me +6% hashrate. Can anyone test it?

Great. My 3900x can do 14000 H/s now.

Really impressive jstefanop, which cooling solution are you using? and what temperature your 3900x is working.

guys who where telling me that 2 memory sticks will be cap, and there wont be any speed increase if i add more memory where wrong. Ading 2 more sticks to my current system increased my performance by 10% without any over-clocks. Video : https://www.youtube.com/watch?v=xeVhjAfgMqw&t

That is an interesting find, I would not have thought that anything other than dual channel memory or quad channel memory(in a system that supports it) would have an impact the hash rate. It makes me wonder if populating all the memory channels in a threadripper system would have similar results. I do not think the gains are enough to warrant the extra memory, but it would be a fun experiment just for the sake of science.

I like your build in the video, the MSI cards look pretty sweet

Yes its all about caclulation best price per hash. Like my RAM was quite cheap 3600 mhz 8gb CL19 was 50euro for a pair. So it makes sense to pay extra 5% to get 10% speed increase. I wonder if i had better quality ram, would it affect my performance.

P.S man these MSI RX5700 are so sexy they really feel premium cards in metal case.

Yes, the theory is that having more independent memory ranks is better for RandomX. Two dual-rank sticks are better than two single-rank sticks, 4 same-rank sticks are better than 2 same-rank sticks. But more sticks and dual-rank sticks usually mean worse timings, so speedup is not guaranteed.

Can anyone proficient in Linux try this RandomX boost guide?

https://www.reddit.com/r/MoneroMining/comments/e962fu/9526_hs_on_ryzen_7_3700x_xmrig_520_1gb_pages_msr/

I was able to get +5% on my R7 3700X, I think 9526 h/s is a record for this CPU now.

What kind of power draw are you getting with this setup, I imagine its something north of 150+ watts for the cpu give or take 10 watts.
Right now it's 9614 h/s and 156 W @ the wall (51 W when idle), so CPU itself is drawing 105W. I haven't tried to optimize it yet and I have Vega 64 idling in that PC too, so it's not very efficient.

This setup got me to 8880 h/s from my original 8444 h/s on a 3ghz threadripper and dropped the power draw by about 9-10 watts going from 185 to 175-176 at the wall. I am sure I could get it to 10000+ h/s but that would take water and a much larger power draw. Pretty happy with this gain and drop in power consumption

I tested this RagerX yesterday and it was slower than XMRig on my R7 3700X. 8200 h/s RagerX vs 8450 h/s XMRig (all stock 3700X with tuned memory).

well as your the xmrrig dev and are prob optimising your miner for your own equipment its not really a fair comparison is it?
I've seen comparisons where xmrig ran without large pages or where tester was recording a video on the same pc while testing xmrig's hashrate, now this is what I call unfair Cheesy My equipment is pretty standard, I just make sure everything is tested in perfect conditions - properly tuned, no background programs eating CPU, updates and unneeded Windows services turned off etc. I need this to easily reproduce the same hashrate at every test - it's hard to tell if some change in the code improves hashrate +0.1% or makes it worse -0.1% without this kind of stability.

"According to the devs..."

Why does CMB publish this kind of crap without any attempt to verify the outrageous claims.

Any miner that locks you into their ecosystem is to be avoided. There's no telling what kind of malware
might be buried in their OS.

No one is going to magically come up with a new faster implementation. There is strong competition between
xmrig & xmr-stak, not to mention Tevador's reference implementation. I doubt there is much room for improvement.

I finally ended up going down to a 3 GHZ clock speed on the threadripper 1950x cpu with 3400 ram speed and a gtx 1060 sitting idle. The cpu temp sits around 62-63c with a Noctua U14S and 3 low power draw case fans to make sure I have decent airflow. I am getting 8444 h/s with this setup while drawing about 185 watts at the wall and keeping temps at an acceptable level. This is not a profitable setup but it is the most efficient setup for a hobby miner with a threadripper they want to play around with and not overheat.

I got a R 9 3900x up to 13.15 KH temp at 66c mining rx,it did out of the box with 3200 speed memory 11 KH so i bought some 3600 memory because of something i saw on YouTube, I'm sure i can get it up to 14 kh easy once i get a better cooler.
I also have a r 7 2700 up to 4.71 kh due to memory limits, I have some 3600 speed sticks coming.
i also have a r7 1700 that does about the same as the r7 2700

and a r7 3700x i haven't really booted up yet the motherboard board and memory is due in today.

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

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.

I think it is so high cause most of the miners have CPU which are sitting idle, so it makes sence even to put on a celeron which does no harm to earn extra few cents. Still ROI is better then mining any other coin with GPU.

you guys should check out this new pool http://get-monero.org if you do not mind using my affiliate link or check out RagerX.lol if you do.

The out of the box hashrate for RagerX is 11500 (about 1000H/s faster) without any tweaks. (with tweaks should be faster)

here is the tele for the pool https://t.me/ragerxlol

3.5% pool fee but the new pool miner combo is 10% faster then all current mining software so you are still 6.5% up on every other miner.

Also the more friends you get to mine the more rewards you will also get paid out from the pool fee.
nice attempt to hide real scam site behind a link get-monero - but NO (cookies has been deleted)!  Grin
Who do you think you are and why do you shy to link an original site (scam alert or not)?


http://get-monero.org is what i'm using as a shortner for my affiliate link for the mining pool the link is ragerX.lol which i also provided for people who do not wish to use my affiliate.


so what are you on about or do you believe no one can code a better pool or mining software then what is currently available?

I was able to get the hash rate up up to 9300 h/s on a threadripper 1950x with a small jump in memory speeds up from 3200 to 3333 with stock cpu settings. The heat generated even with the cpu fan running full blast seems a bit much, so I will probably run with less cores until I can get it to and acceptable level.

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


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

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

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

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

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.

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


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

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...

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.

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.

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
...

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.

What cooling you using, is it the stock air cooler?
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.

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.

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.

FSB:DRAM 5:54
CL 14
tRCD 16
tRP 16
tRAS 36
tRC 84
tRFC 631

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.

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.

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 feedback
3rd 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 🤞

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.

as long as you dont go higher than manufacture's maximum rpm then is okay,

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.
I think you need to find that balance to not overpay by every hash. In some cases it might be better just to reduce the OC and get reduced 10% hashrate and power then purchasing expensive cooler. Everything comes down to OPEX and CAPEX.

anything over 80c will destroy your cpu in a few months

My 3x ryzen 9 3900x all use water coolers.


I have  an

evga  cooler = https://www.amazon.com/EVGA-Liquid-Cooler-Cooling-400-HY-CL24-V1/dp/B074WH52BW/ref=sr_1_1?
corsair cooler = https://www.amazon.com/Radiator-Advanced-Lighting-Software-compatible/dp/B077G3C6HH/ref=sr_1_4?

What are the temperatures like with the stock cooler?
I was using the stock cooler with R7 1700 and I managed to get it to run @ 3.9GHz all cores but the voltage was so high and the power draw that it consumed around 210W from the wall, Veg 56 GPU was idle and temperatures reached 80 C.

Temperatures was quite hot 83C after working for about 30 minutes. But my room temperature quite low about 15c.
This was just overall test, ill have more efficient ram by end of the week.
Need to find that sweet spot where you reduce core voltage and not loose to much hashrate. To not get the CPU to hot with stock aircooler.

Power usage from wall is 260w.
   is it with the  gpu in idle?
GPU was idle yes.

Test bench setup :

Ryzen 9 3900x with stock air cooler

2x Gskill 3000 16gb C15 RAM modules

MSI B450 Tomahawk MAX motherboard

1xRX5700 for image

Superflower 750w GOLD powersupply

As there are few of the coins switched to RandomX mining algorithm already and one of them is Loki. So on stock settings everything out of the box we where hashing Loki at 11500 h/s. Which is about 5x then in our previous best tests with Intel i7 8700k out of the box 2360 h/s. Power usage from wall is 260w.

So we tried to push little more speed on the Ryzen 9 CPU , by overclocking it in motherboard BIOS. Changes done :

OC Explore mode to expert

CPU OC ratio to 4100 mhz

A-XMP to enabled

Precision Boost Overdrive to disabled

Play with DRAM timings (lower the values)

CPU core voltage to 1.250v

Increased Dram voltage 1.300v

This setting got me up to 12650 h/s mining RandomX. I was playing around with different kind of ram stick , and seen significant mining performance decrease with lower performance ram. So i have on the way 4x3600mhz 8gb stick and will do a proper performance test when they arrive.

So the 12650 h/s if you would be available mine monero today would be 3.5 usd , even that it got 10% price drop today. But you know it is not the case, impossible to predict what kind of total network hashrate will be when Randomx launches. As the total network mining structure will change and the current hardware will be unprofitable. Current Monero network hashrate is around 300 mh/s.

Profitability with Ryzen 9 mining Loki which is also RandomX mining algorithm. Daily profitability is 0.70usd

Im eager to see what RandomX mining will bring to Monero mining. What is your thoughts?
