Topic: lolMiner 1.64: Fastest Kaspa miner in market - page 142. (Read 156032 times)

Confusing about 8 vega's rig.
Linux, 0.42, "DEVICES" : [0,1,2,3,4,5,6,7] or "AUTO"
Trying start with all GPU used. Miner will work only 1st 5 GPU(0,1,2,3,4), speed for GPU 5,6,7 = 0 and power consumption about 20-30w(idle).
Does not matter what GPU used, miner works only with 5.
But! If i run 2 miners with 2 configs  "DEVICES" : [0,1,2,3,4] and "DEVICES" : [5,6,7] all devices works fine with full load and good hashing.
For me it not problem run 2 instances, but anyway...
Any ideas?

Hello! Can we expect more performance in the near future (rx570,144/5,BTCZ)? I guess the + 80% is also true for it. Congratulations to your job!

Currently you can not and I think that will remain so for a while. Why?
Well because there is no way doing that for AMD and Nvidia for all OS (Win 7, Win 10, Linux) the same way.
So the codibg would bind a lot of capacities at my side (I develop this miner alone alongside my dayjob and family) that I rather spend for creating better minibg code. Furthermore it is a matter of resposability. A corrupt kernel code can make a rig hang and can make it require a reboot, but thats it. A bug in overclocking or fan setting routine can physically harm hardware - that I do not like much. Maybe I will do temp reading in future and provide it over the API but I do not think fan or OC setting will come anyhow soon.


You are running with config file? Then you can modify the profile of the coin (or default section) by adding
For example to run on first and 3rd GPU but skipping the second. Note if you put this to default section it will be overwritten by a devices entry in the individual profile.
For command line use it should be doing the same thing.


Hmm something is wrong here. The speed you see is much higher then I would expect for this cards - I rather would think about 30 to 35 to be realistic.  No real idea why at the moment but I think something in tge filtering is broken. The miner after last round checks the solutions and filters out incomplere ones. Seems that does not work here and more solutions pass the check then it should. No idea why, but this is not good.

The warning message you got is no problem. This has something to do with a bit fancy pointer magic in GPU code ^^ But I wonder: this messages should not be displayed - you are certainly running 0.42? I think thats an older version.


Doesn't work at yours? What driver you use for the vegas, the ROCm or the amdgpu-pro?
I have no vega myself, so can not trst directly but with some detail info I think we can debug it


I think there os a bug - your 30 to 33 sols / s is more realistic and in region so I am shure the solutions are all valid. I think in his case something is broken, but will have to see what exactly.
Hope in future versions to put some sol/s on top of cause. New code is already work in progress

I'm able to get lolMiner working with two Vega 56's on Ubuntu 18.04.4 with amdgpu-pro-18.30-633530.tar.xz (legacy and pal both installed) by symlinking libamdoclsc64.so to libamdocl64.so and making certain I had the 'video' group on the user running the miner.

However, I'm with wojcieh and am only able to get 31-33 sol/s out of each of my two stock MSI airboost vega 56s (I undervolt them, but even at normal voltage I get max of 33). Are you seeing that 56 - 63 sol/s performance only on Windows? Did you make vbios changes?

That's a pretty amazingly dramatic performance improvement.

seems it doesn't work for vegas on linux

I'm actually mining some BTCZ again WOOT!

Using lolminer v041

Its actually doing a good job. Very stable.

Mining on a wide range of AMD cards. So far so good on: 7950, 7970, 280x, 290x, 380x, 390x and RX 480's (wont run on HD 7870 nor R9 270x)   

Now we just need that price back up to 65-150 like the good ole days

THX dev for the miner! keep improving it!

there s no profit on mnx coin. for rx cards. i hope its gonna be some updates

SigiSinatra, what are your system, driver and cards parameters? overclocked? i menaged to get only ~33sol/s per vega 64

Benchmark shows this on my 56/64 vega rig for 144.5:

...
Average speed (5s): 62.6 sol/s | 56.0 sol/s | 56.6 sol/s | 61.4 sol/s | 60.4 sol/s | 44.0 sol/s Total: 340.9 sol/s
Average speed (5s): 63.2 sol/s | 58.6 sol/s | 58.6 sol/s | 59.8 sol/s | 59.6 sol/s | 43.2 sol/s Total: 342.9 sol/s
---------------------------------------------
Average speed (60s): 61.8 sol/s | 57.2 sol/s | 56.7 sol/s | 61.5 sol/s | 56.9 sol/s | 46.4 sol/s Total: 340.7 sol/s

Lollie,

You seem to be the only dev taking a crack at new Equihash algorithms with different N,K parameters for AMD. Have you looked at all at AION's POW? It's N,K params are 210,9; I'm quite interested in this project, unfortunately currently only nvidia cards can mine it. I'm sure you'd get a good chunk of people like me using your miner if you can crack it!

It's more demanding on memory... so I'm hoping that a miner optimized to the Vega's HBM2 could be competitive with the CUDA Nvidia miners.

Hello everyone, did some testing today with old cards (hawaii and tahiti).

Modded bios on every card (mem timings), slightly overclocked, some cards underperform, due to the lack of good memory timings.
60s avarage speeds
hawaii devices (0,1,3,5,7,8)
tahiti devices (2,4,6,9)


So overall performance is not bad, but i think there is some potential for improvement.
Comparing the old equihash 200,9 hashrates from those cards to a nvidia 1080ti with zhash hashrates (only comparison i can get first hand) we get 400Sol/s from a 390X vs 780Sol/s from a 1080ti. When mining Zhash, we get: 27 Sol/s vs 70 Sol/s for now, mining ethhash would be like 30Mh/s vs 52Mh/s. So the difference between the two cards would be somewhere like < 1:2. I think there are some other algo's with a similar factor between the two cards, so if there is not more potential for like 5-10Sol/s i would be sad.

But for now great work Lolliedieb!
Thats my feedback for old AMD cards (they have still juice ), running longterm test with these 10 cards now.

Hi. Can i use only 1 or 2 graphic cards of my rig? No matter what i do lolminer is using all of cards and i want to shut down 1 of them. Can i do it?

How can I control the speed of the fans directly in the miner?

Ah ok, what I see is my card runs with stock clocks, so 1366 MHZ - that could explain at least a few %. But likely your setup is more energy efficient
Lets see if we can still find a few % for you by writing better code

One with 4GB Elpida memory with best timings available in this forum & speed set to max. 1999 MHz, GPU at 1250 MHz.
The other with 8GB Hynix also with best timings at 2050 MHz & GPU at 1250 too.
Both cards give me the same speed, about 14.5 with 0.41 & 20 with 0.42 (average, not peek).
Blockchain drivers & Windows Server 2008 R2

RX  580: 12.5 sol/s (0.41) → 22.5 sol/s (0.42)   (+80%)

OMG, that's much better, now AMD can mine with profit

Depends... when 580 can do 22 and 1060 does 26 - they are not too far appart ... same as with 33 (vega 56) vs 1070 speed.

Atn mining is not that profitable it used to be half a year ago with prizes up, but at new versions sol/s it should be profitable - of cause depends on coin and energy price.



The miner has a simple api. Zergpool stratum? Whats different there?


Of cause its almost always possible, but the jump will not be so big again. Maybe 2 to 3 sol/s on top for 144/5? Ok, maybe more but as with every trick the dev has to find it first



Thats odd - before yours was much faster, now slower.  Hmm ... most changes targeted the memory controller, maybe different vendor of mem chips?
My testing gpu is a saphire pulse 4g at stock clocks, what is yours?

For me with my 2 RX 580 change is:
14.5 each to 20 sol/s (+38%)

Go this way, when it reaches 100 sol/s per card it will be profitable 

Tell me if i'm wrong but at this speed it is still not profitable, am i right ?

Anyway good job for the dev. We just need a little bit more amd hashrate and you'll have a wave of fee's incoming
