[ANN] coolMiner - Lyra2z Miner for nVidia [Maxwell\Pascal\Volta\RTX]

[JackIT]

Test 2 results are in: https://bitcointalk.org/index.php?topic=4412370.msg39718659#msg39718659

JackIT: what do you think,  next round on same intensity 20~19 but without static diff? it looks like the Var-diff gave better results(or 10 diff was too low?).

I think it's safe to assume that coolminer produces more coins than ccminer, and so I'd like move on to testing various settings for coolminer.

Next test will be coolminer with and without static pool diff.

Thanks, I am also interested on Var-Diff vs different static diff relative to hashing power, it's seems it can increase/decrease income regardless the miner used, really interesting tests you are doing as a service for the forum- GJ.
P.S - in the first test I was very curious why pool was choosing almost double the diff for coolMIner, even though I was thinking it was too high- it came out to be better choice by the pool stratum?
P.S - I advice you to choose the lowest intensity that doesn't reduce the hash-rate (+- 50kh\s acceptable), as you have seen the speed penalty is lower then on ccminer, and maybe this way less rejects of job not found/discarded work because new bock, it should be around 18~19. and other rig you can try 20~22 what you like.

Yiimp pools adjust diff in order to achieve 5 to 15 submitted shares per minute. The fact that 5-15 is such a wide range, it can easily lead to double diff of small numbers.
What I did notice with coolminer is that, static diff penalizes the miner immediately after the dev fee is run. instead of the pool diff ramping up from 1, it was immediately at 10.

I run -i 18 on all of my other rigs, intensity doesn't seem to make a big impact on Lyra2z. I'll probably test different intensity setting in future tests.

TEST 3:
Head to Head test of CoolMiner 1.3  - static Vs variable stratum diff

PREVIOUS Coolminer tests: https://bitcointalk.org/index.php?topic=4412370.msg39718659#msg39718659


Sometimes setting a static pool diff will yield more coins, sometimes it won't. Finding the optimal static diff is really difficult, you're often better off letting the pool set your diff.
Anyhow, this test is underway to see how setting a static diff of 10 (aprox 0.7/MHs)  versus letting the pool set the diff will impact the amount of coins you earn.

Caveat: I have no idea if a diff of 10 is the optimal choice.

The Setup:
I use a 12 GPU 1080Ti rig on Windows 10, split into three mining instances of 4 GPU's each (for this test, only two of the instances are used). All three mining instances are balanced to get as close to the same hash rate as possible.
Each mining instance is running at the same time on the same machine mining on the same pool.

Overclock settings: 100% TDP, +75 core, -502 mem
Drivers: Nvidia 397.93
Intensity: 20

Test Results: No meaningful difference
Duration: 667 mins

• [CoolMiner 1.3 - var diff] 48.90 MCT Pool Link
• [CoolMiner 1.3 - D=10]  48.52 MCT   Pool Link

NP, thing is that I was playing with the code for months so I remember how it works  .
Thank you very much for your time, its real fun to watch the competition  .

Edit: it's interesting, on first run my miner@16 intensity  had clear lead on ccminer @ 22 intensity but now it's like ccminer works better at 16 intensity, (unless we have troll here who tries to send shared to same address lol).

Moreover- this pool stratum is't very smart and wastes your hashing power, coolMiner is stuck @ diff 18 while ccminer @ 12, this is very bad since I see blocks comes to pool every 30~60 sec and that means that card are stuck in loop for finding too high diff share and every new block it breaks out from loop and you got no share.
The lesson from this is not to trust the pool and set the Diff according the hashing power and block per min so you can send shares in time between blocks.
Edit: now it set diff = 26 on coolMiner(faster rigs get higher stratum diff ), there is no chance 4 1080Ti will send enoght shares in between new blocks(few seconds).

Edit: if you can- next run  try testing it on 21 intensity like many miners used on 1080Ti till now, and set static diff on the miners so there will be no Diff changing factor.

So what would you recommend setting the Diff to for 8-1080ti's?
How do i calculate the diff myself?
And what is the multiple per 1080ti? In case i have  to group my gpu's.

[Ryzen2700x]

I am not sure, this id why JackIT's test is so interesting, I will wait for  the results.
P.S, its good you are testing against d=10, this way the last test relevant and it gonna tell us if and how fast this miner would be @ -i 20 and Var-Diff against ccminer @ d=10.

Hi Guys, i'm getting an error on my mining rig when using coolminer, its "The application was unable to start correctly (0xc000007b) ... "

Its a windows 10x64 machine 8 gb ram , core i5 7400 , with 9 gpus , 6 x 1080ti, 3 x 1070ti.

Things i've tried, installing cuda 9.2 , installing latest nvidia drivers 398.11, checked vb.net version is 4.7 , ran as administrator , checked its not blocked in firewall .  Tried 1.1, 1.2 , 1.3 version and no luck.

Any ideas ? works great on my desktop and love to get this working on my rig.

I'll send a Gincoin to anyone that can sort this out for me as a thankyou .

Try this:

Go here: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

download and install both: x86: vc_redist.x86.exe and x64: vc_redist.x64.exe

Ok tried this and no luck , its the same instant error message "The application was unable to start correctly (0xc000007b) ... "

This is one stubborn problem :-(

I'm having issues with this miner, I create the bat file and when I click on it the miner window appears and then disappears really fast. Enemy Miner works fine and so does CCminer. What do I need to do to fix this?

Yes. searching on Google  shows that many had this problem from many reasons, in my opinion if it mining rig without important data, is much faste to have fresh install on win10 then debuging and waistin hours/days to fix this kind of problems, you should decide if this worth the effort.

I'm having issues with this miner, I create the bat file and when I click on it the miner window appears and then disappears really fast. Enemy Miner works fine and so does CCminer. What do I need to do to fix this?

Try adding pause at the end of bat file, this will let you see.

Can you share the bat file u are using? just hide the -u .

[Eketubol]

This is my bat file

coolMiner-x64.exe -a lyra2z -o stratum+tcp://eu1.protopool.net:4553 -u  -p c=PYRO
pause

[Ryzen2700x]

Do you see the error now after adding pause? do you have drivers with cuda 9.2 support?

[JackIT]

the static Vs var diff test has been neck and neck the entire time.

interesting stat at this point..

var diff has 1160 accepted shares
static diff has 1906 accepted shares

and it's a been pretty much a tie, in coin production

[Eketubol]

It says that I don't have 9,2 support. I am on driver 390.77

[Ryzen2700x]

That the problem, you must update the drivers to use it.

A good test would be to try running ccminer 2.2.5.  Does that work or does it produce the same error?

Also, does that happen if you double click the exe?  or is it happening when you use a bat file?   sounds like it could be a missing dll file.


Try running command prompt as an admin and running this command:  SFC /scannow

[nsummy]

Ryzen, you are my hero. This gives about a 6% performance bump on my system, but more importantly, it hardly produces any heat!!!!!!!  People bitching about dev fees are idiots.  Lyra2z runs so hot on ccminer, this is a godsend.  Thank you!

ccminer 2.2.5 is fine and that's what i currently run. No error with that one.   I tried the SFC /scannow and no errors.

Re Ryzens2700x comment about the full reinstall i'm worried i do all that and it doesn't fix it. I've already lost 4 hrs trying to get this going now . So happy to try a few more things first for sure.

Test 3 results are in...

No difference between letting the pool set the diff, and manually setting a diff of MHs x 0.7

Sorry guys, this was originally supposed to be a coolminer 1.3 -i 18 Vs -i 20 test, but I choose the wrong miner in setting up awesome miner.
