Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[jackbox]

I am using Claymore ZCash/BTG Miner v12.6 with Windows 10 for some AMD gpu cards.  I decided to mine a different coin that has the Equihash algorithm.  After I open the .bat file Claymore opens and immediately displays in red font "Unknown Option" for the wallet address.  Claymore continues to run, it connects to the mining pool server, the hash rate speed is fine.  Why does Claymore not recognize the wallet address I have entered in the .bat file?  What is wrong?

The wallet address is used with EWBF for my Nvidia card and it works fine with that miner.           

This is what Claymore displays after I run the .bat file:


C:\Users\xxxxxxxx\Desktop\Claymore Miner v12.6>ZecMiner64.exe   -zpool pool.com:5555  -zwal wallet address.worker  -zpsw z  -ftime 1  -i 6  -tt 75  -allpools 1
UNKNOWN OPTION wallet address.worker

Got the same problem

You have to replace "wallet address" with the address of your wallet or login name for your mining pool and change "worker" to your worker name. Since there is a space between wallet and address it thinks you are trying to input an option. Also, why are you tlrying to mine the worker without putting in your info to get paid? You also need to change "pool.com:5555" with the URL with the address and port of the mining pool.

my 7950's do 270 sol with this software, seems about right i guess?

cant believe i got hold of 2 7950's for 150 bucks in these times, not counting on any huge profits ofcourse, just some hobby mining.

You might be able to get 300 sol if you do a little overclock with core and memory.

Try 1100/1575 or something like that and see if its stable.

Yes you got really lucky.

I remember you could buy the 7950 BRAND NEW for like $199 back in end of 2013.

for some reason one rig cannot mine zen or btg on multipoolhub and equihash on nicehash, zcash and zclassic works fine, -allpools 1 won't change, gpu load is flat line and miner says 20s work time out, tripple checked ports' numbers and tested on another.

theres an option called esm or edm or something along those lines (check readme), set it to 2.

That is right. I still use my 7950 to run the ZEC. I get about 250H/s with 830/1250 as I undervolt a lot.

Sorry if this is discussed previously but can't find it.

I'm using zecminer via NiceHash, but I think that's irrelevant.  Last night the program switched to zecminer as the most profitable, but when the program ran, it reduced the intensity, thereby dropping the revenue by an order of magnitude.  (I noticed GPU temp was only 44C).  I verified this by running zecminer by hand.  When it starts, it says the graphics card doesn't have enough memory, so it reduces intensity to 4, rendering it pretty much a waste of time.  It makes no difference if the higher intensity is a default or if I specify it explicitly as a parameter value, it still gets dropped.  All recommended environment values appear to be set correctly.

Windows 10, AMD R9 270X, 2G, 15.2 driver

Is there a workaround for this?  I could take this msg at face value, but I could have sworn I ran this previously on a different computer with the exact same model card and it ran at high intensity.  (On second thought, I think that one was running the newest AMD drivers - wonder if that might make a difference?)

OK so I got curious and went to the trouble of setting up the older system again.  Apparently the default intensity when zecminer runs is 6, on a scale of 0-9.  It gives the error msg that there is not enough GPU memory on both systems, and drops to 4. At which setting performance is awful.

But, on my previous system, I see that I had the intensity explicitly set to 3.  Setting it to 3 on both systems cranked up the speed to max, as far as I can tell.

This makes no sense to me, but it's what's working right now.

On a side note, for some reason Nicehash is running CryptoNight on my previous system, and Equihash (Claymore's zecminer) on this system (exact same GPUs, as noted previously.)  They have different speed CPU's, etc. so that might have something to do with it.

I'm trying to get v12.6 to work on Ubuntu 14.04.1. I have to stay on this version due to my old graphics cards (HD7950).

When I try to run it, I get the following error:

Code:

./zecminer64: relocation error: ./zecminer64: symbol _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEC1EPKcRKS3_, version GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference

Through adding ppa:ubuntu-toolchain-r/test, I believe I have a later version available, i.e. GLIBCXX_3.4.24.

Did you set the PC virtual memory to high value? It should be about 4G for each GPU.

Did some searching and haven't found anything.   Anyone have problems with more than 10 cards using 12.6.   Past 10 it seems to randomly drop a card from hashing and the card that's dropped changes each time the software is restarted.   I've tested this setup with Claymore ETH and Dual and all cards work successfully, but ZEC only allows 10 cards.  Anything past that seems to pull zero hash.  

A little more info.  Win 10 Pro, 11 cards total.  7 Sapphire 580 Pulse, 3 Sapphire 580 Nitro, 1 XFX 580.  All 8GB cards.  All BIOS modded, and OCd as well.  Again no issues when running Claymore ETH and DUAL.

So I tried a few more tests.  I can load 10 cards in ZEC, but the 11th fails each time so I thought maybe I could load 10 in ZEC and 1 using ETH/DUAL.  That also fails.  10 will load but the 11th I get a DAG creation error.  It's almost like there's a limit of 10 set somewhere.   However if I try straight ETH/DUAL mining 11 cards work fine.  

I'm pretty confused

OK figured it out.  I had the VM in Win set to 16GB but apparently that wasn't enough.   Upped it to 20GB, and now all cards load on start.  Hope this helps someone else if they get the same error.

Hi I have AMD R9 285 (2GB) GPU card and with this algorithm ZecMIner64 (v12.6) I get only about 96 H/s with Nicehash Miner.
That seems to ber very low.. I should get at least 3x more (according to nicehash profitability calculator) . Other algorithms works as expected (right speed).
AMD Driver is 18.1.1

Any Idea whats worng?

Play with intensity settings:

-i   mining intensity. Possible values: 0...9. 0 - lowest intensity and CPU usage, 9 - maximal intensity. You can also specify values for every card, for example "-i 2,5,6". Default value is "6".
   Note: reduce intensity if you get low speed or miner is unstable. Also check several values to find the best speed, for example, "-i 8" can be a bit faster than "-i 9" in some cases.

hello i found this in google https://noticiasbitcoin.io/2018/02/01/equihash-gana-aceptacion-como-algoritmo-pow/
and after read it i just come here to get some info. My gamer pc has a XFX RX580 8g . what config and miner i should use to mine Zcash ?

It's more profitable mine the other equihash coins ? thx bros , if you can reply me or pm i wait it...

Hello guys!
Want to remind to all of you, that if somebody has any problems with stability of EWBF, DSTM, BMINER, CLAYMORE, CC miners or needs some extra control over your rigs please read carefully my message below.

I want to introduce you a script, which can solve most of your problems. It is a result of half a year hard work with my beta testers. Now it is clean of any bugs and ready to be introduced for the wide mining community.

1) https://bitcointalk.org/index.php?topic=2071108.0
2) https://forum.z.cash/t/cmd-equihash-miner-autorun-autorestart-watchdog-for-ewbf-claymore-dstm/20640

It will definetely reduce your valuable time spent near your rigs, because this script will do all the work for you. Just start it and forget about your rigs, relax or do anything else. In case of any problem this script will restart your miner, or the rig, if necessary. It will notify you by Telegramm message about all problems and corrective actions taken. It is open source code (CMD/BAT, not an .exe or something like this), so anyone can check throug the code if needed.
Enjoy your life, let the script to monitor your rigs for you.

quick question , which is better for this miner ? GPU core speed or GPU RAM speed ?

Typically with Equihash, overclocking the ram will produce an increased hashrate.

quick question , which is better for this miner ? GPU core speed or GPU RAM speed ?

Typically with Equihash, overclocking the ram will produce an increased hashrate.

Claymore's ZCash miner:
Overclocking the core clock speed increased hashrate. Overclocking or underclocking the GPU RAM actually decreased hashrate, with overclocking also decreasing GPU stability.

That doesn't make a whole lot of sense to me given that Equihash is a memory hard algorithm. Its possible that increasing the gpu clock might help some, but that's not what's doing the majority of the processing so it should not produce a significant change in hashrate. I'm not sure what your doing, perhaps this depends on the type of card your dealing with, however, the above is my experience with the R9 380X.
