i dont understand why i cant get above 900 for almost all cards..any advice?
P.S. ignore cn_config order as it is not the same, just 4GB has 7+7 and 8gb has 8+8 results and my cards match,thats important.

It has varied a little with other parameters, I think a general ballpark nr would be around 1475-1500 cclk. I have data for a range of tests, but some things in the kernels have changed since then so I would need to validate the data again.

I'm looking at some of my stats being show in the tool.   I have a rig with 9 GPUs and I see that the number of results for each GPU varies quite a bit.  I'm at 300 results and one of the 9 GPUs shows 46/0 while the lowest shows 23/0.  The cn v8 hashrate avg is 2.178khs and 2.102 khs so they are pretty close in speed which leads me to think the lowest GPU isnt getting enough work.

Are the jobs balanced across the GPUs evenly or is there some other mechanism?

Also, how long should it take before the reported pool speed matches to what I see in supportXMR or MoneroOcean? I know the dev fee will take a small amount of the totals but I am seeing a pretty large difference between what the GPU average is and the pool rate.  Almost 1khs.  There arent any reported failures.

Two options: if you don't provide -d x,y,z on the command line, we enumerate the devices in the order provided by the OpenCL driver. This means it will match some tools, but not others. If you do provide -d x,y,z, those numbers still refer to the OpenCL order, i.e. you're picking indeces from 0..N-1 from the order that appears when starting the miner without -d. We'll then reorder and set GPU0=x, GPU1=y, GPU2=z.

The OpenCL order is also the same order as displayed by the "clinfo" command which dumps a shitload of data about your cards, available in any OpenCL environment.

For automatic reordering, we don't have a bus reordering option right now unf, it's on the TODO list. For mapping against other tools, we do display the PCIe bus id on startup in the "Successfully initialized..." lines, and also provide it over the API in the "devdetails" command.  For example:


Client request:
{"command":"devdetails"}

Miner response:

      "Model": "Radeon RX Vega",
      "Device Path": "0b:00:0"
    }
  ],
  "id": 1
}


For reordering, as you can see my two cards on this ws are not in bus id order in the OpenCL enumeration. Given that information, I can manually reorder using -d 1,0 when starting the miner, and my Vega would be GPU0 and the 580 GPU1.

Of course it's annoying to manually reorder, and we'll add a reordering option soon, but at least it is possible until then.

cpu usage more then other miners, some work offloaded to cpu from gpu 

miner speed great btw

Here are my experiences and collection of facts with TeamRedMiner (in rest of the text: TMR) and Vega cards so far.

I have 7 rigs with Octominer riserless motherboard, 1200HP server PSU, each rig having  7x Vega 64 or flashed 56, using power tables from vega mining guide.

1. Compared to JCE Miner and SRB miner, I have increased my efficiency from around 9H/W to over 10H/W (10.50 is my rigs average i believe), mining fee included. I did not log all the data and make exact calculations, but the efficiency of TMR is at least 15% better than previously best miners. If you don't care about efficiency, you can reach incredible speeds with Vega cards, and dev fee is well worth of it.

2. TMR causes power usage spikes. JCE and SRB miner mine in a "smooth sailing" way, where the power consumption is constant. Do not tune TMR at the edge of your PSU limit, leave some headroom. These are not big spikes, but they are there and they can crash your rig or burn your PSU.

3. If your rig is stable with srb or jce at certain frequency and voltage, it doesn't mean they will be stable with TMR. 3 out of my 7 rigs simply swapped from SRB to TMR, and work stable ever since, i didn't even put yet new TMR versions on them. However other rigs had many stability issues.

4. Unstable rigs now have 0.3.6 version and a mix of 18.6.1. and 18.10.1 drivers. They were shutting down for all kinds of reasons, and even corrupt the drivers and cards disappearing from the system. Now they work ok with 0.3.6 but i can't overclock them. This is already issue with binning of the cards and luck, nothing with the TMR.

5. It took me approximately 2 days of partial downtime and 1 burned PSU to get TMR running stable. This is because I was chasing maximum performance instead of efficient running, I was even running my 1200W psu at more than 1400W because I was excited with incredible hashes that TMR can spit out at high core frequencies. Don't be me, respect your hardware. Still, this will quickly pay off through increased hashes and reduced power usage (it will take me around 20 days to pay downtime and burned PSU, not so bad!)

6. 16+14 config always gave me best hashes per watt, no matter the speed of GPU, however, I did drop to 15+14 on some of the rigs during troubleshooting as I suspected that rigs with very slow CPU have issues with 16+14 for some reason. It is up to you to find your setup that works for you.

TMR is hands down the fastest Vega CN8 out there, that negates increased power consumption that CN8 brought to us. It is well worth to try. Dev fee of 2.5 % may seem high but it is worth the price, the devs are active all the time and try to help in every way.

There are 2 things that I would like to see.
1. Miner uptime. Maybe on some of the lines the information about miner uptime can be squeezed into.
2. Watchdog. Once i got my rigs stable, i didn't experience single GPU dropout. however, sometimes it happens that miner starts and initilazies all the cards, but hashes are 0. Some simple watchdog would be very useful for such occasion.

Any chance to add support to other CN variants? 8GB cards are great with 4MB scratchpad algorithms.

Windows 7 ?
does the miner work?

Another question.

How are the GPU|N calculated? Based on PCI or some other method? From what i can see, GPU|N corresponds to the same way, they are shown in the AMD Driver panel. GPU0 is GPU0, and so on, and thus meaning, it is probably NOT PCI related.

Other miners on cnv2 can also reduce power consumption footprint. Try worksize 16 and 32 you'll notice power consumption will reduce but so do the hashrate.  TRM has achieved a balance there.

Right now whenever a card is hung the miner still goes on with other cards.  This might be desirable in some cases but it would also be nice to have an option to crash the miner itself.

No problem - more to come.  Good to know i'm in line.  At what point (effective clock) do you see 16+14 start to make sense?


Exactly what I was thinking - might take a look around to see if there's already something like this out there.  And great to know you're on top of the other issues.  Keep up the great work!

I assumed that it would be like that (4GB cards here), but was not sure. Using Windows, and the Windows driver limitation for the max VRAM allocation should be ~3584MB, and 8+7 sounds like it would use more than that... but it works

Ah, we should integrate the CN config better into the API.

The numbers are only about the nr of pads per thread, so directly related to mem consumed. The +- is a little mode tweak that sometimes does nothing and other times something.

If your cards are 4GB, 8+8 would consume everything, and it won't work. 7+7 or 8+7 should be doable depending on how much the driver has grabbed on the card(s) already.

Ops, sure did miss that.

I may have missed the answer to my next question:

Since the 570 and 580s have 32/36 CU's, why they both run at 7-7/7+7 ? None of my cards liked 8-8/8+8, while i see some people have run them at 8-8/8+8.

And what exactly does the CN_config do? The miner API reports regardless of the CN_config values.

It's an unfortunate side effect of the algo and the efficiency level of this miner in the various stages of CN. I'm 100% sure we will solve it in a good way in the end though. See I reply I wrote ~30 mins ago here: https://bitcointalksearch.org/topic/m.47528064 for more details.

A clarification for the Power Usage though - i observed it, and although lower, it would still spike to ~20W higher than the average. Not sure if you have observed this.

Ha! That would def be cheating, wouldn't it? No, I can assure you that the lower power draw is from the continuous gpu work. After all, cpu verifications are for found shares only, so depending on your pool diff you maybe crunch one CN hash on the cpu every 10 secs (max)? It's tiny work in the grand scheme of things. Love the question though!

Thanks for the answer.

Somethign that came to my mind after reading your answer.

The reason, why the power consumption is lower, is it because there is no CPU verification? 20-40W difference is big, and i doubt it, but does not hurt to ask





Also, if anyone wants to pull API information remotely, and see what the miner reports, you can do with the following:


Be sure to have started minning with  --api_listen=IP:PORT, default port was/is 4028

- no colons, space between the IP and PORT. N = GPU number, [0-9]

The pulled data is not in good format, so you need to edit it.

I have made a script for this:


Dirty stuff, but it works. I left only the most relevant data. Replace again IP and PORT with the ones you need.

Hey pbfarmer! Thank you for the elaborate tests and detailed descriptions, much appreciated!

When running at lower clocks around 1407, the 15+15 configuration have been clearly superior to 16+14 in our tests as well, so your results are well aligned with our own testing.

Replying to the noted concerns/feedback below:


Absolutely agree. We're sloppy at shutdown, and it will be addressed shortly. We need to add proper signal handlers that works for both Linux and Windows and catch the ctrl-c/sighup signals, then do a proper release of all OpenCL resources.


This is a very good point, and we've noted it ourselves, both when designing the kernels and by direct at-the-wall measurements. The issue stems from this miner requiring less power in the long-running main part of CN compared to others, but it also goes full throttle in other parts, requiring more power. Hence, the min-to-max power swings are amplified at both ends. Any CN miner with the same profile as this one that executes the algo in the most straightforward way would exhibit this problem.

We're also seeing a notable difference in stability on the Vega 64s vs 56s. I believe this is part of the problem. The fewer CUs means there will be additional pressure on 8-16 of the 56 CUs compared to the 64s as these spikes occur, a little bit depending on your CN config though.

There are a few ways of addressing this, and if we want to achieve max stability I believe we need to solve it. I have a very good design for solving it, but it's a big redesign and rewrite. We will get there at some point. Meanwhile, we're debating simpler forms of reducing the effect of the spikes, like cutting the worst case scenario in half. We'll go to work shortly on this.


Yep, we're aware that the cgminer/sgminer api isn't really the CN standard, and we have some plans. We've worked hard to keep the miner itself free from any open source dependencies, we've written every single line of code from scratch. For example, that's we're missing on-cpu verification for CN in these first versions, we refuse to steal any code from xmrig, xmr-stak or even the XMR wallet. We'd like to have it clean from attributions.

Given the above, we won't pull in e.g. lighttpd as a dependency in the miner. My plan is rather to implement a separate project that we open source, a little http adapter in C++/node.js/python/whatever that converts the cgminer/sgminer api to an xmr stak-like HTTP/REST api. It will also have the nice feature of working with any sgminer-derived miner, not just our miner. I don't get the point of these massive monolith miner implementations, it would be so much nicer if we would have separated these different concerns a long time ago in the miner dev world so everyone could focus on what really matterns, the kernels and mining process. You can also separate some of the watchdog aspects and place them outside of the miner. Never really a good idea to run a watchdog thread inside the same process it's supposed to monitor.

So, it's also on the TODO list, we'll see when we get there. Time is always the limiting factor . If anyone in the community wants to get involved, give me a ping.

wow crystal
