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

[MTJ151]

One of my GPUs shows "returned incorrect data" it's shappire 290x 8gb RAM 2 others 290x with 4gbs are ok. Anyone knows why?

 Reduce the intensity.
 I have the same issue on one of my R9 280x, that was the only cure that worked.

Confirmed here too... also get the same issue on one of my 280x's.

I have ton of dead Nvidia video cards, especially that EVGA brand, 2 years max. I have been used and abused ton of AMD video cards and none is dead. I promised myself to never ever buy Nvidia chip video card again.

Want to share the specs and how you used those cards? E.g. approx. capacity usage and how many hours did they last before they died? How many alternatives have you tried and what's your personal most durable one now?

So then will the next ver.  appear

In now i used that server zec-eu1.dwarfpool.com:3336 ..my share foun change to 240-280-230 ms...thanks my friend...this better that 300 -400 ms

 Your issue is that Iran has very poor connectivity to most of the world - I doubt there is anything you can do to get consistantly low ping times on the shares your miner submits.

For the ZCash mining, the effect of poor connection is not as bad as the Ethereum  mining as the block time is 2.5 min.

Hi Friends!

Can You advise me- what better to buy to have more H/s in minnig ZEC and spend less electricity?

Which card(s) is more profitable for minning ?

rx390x - 495$

rx390 -  420$

two rx470 4GB ram- 250$   or

two rx470 8GB ram- 304$  (do i need more RAM for mine ZEC or anything else?)

two rx480 8GB ram- 329$

Thank You So much!

Hi, Claymore!
Will drop you in the near future a new version of your miner ZCash?
Can a little more detail about the stability of version 10?
Thanks  

New version will be available in a few days.
I don't see any problems related to stability in v9.1, so if it does not work for you it's possible that new version will not work too.

Today?

The real price for 390 cards is around 250$. Don't look at the old amazon offers which are ridiculously high. However I warn you (and everyone planning to invest in new rigs) that most probably by the time of arriving of the cards, the profit will drop so much that the ROI will be impossible in near future. Look at the plummeting prices of ETH and ETC curently. The pressure on ZEC and XMR is too high now, so they will not hold the current price for long.

You can use the calculator http://www.whattomine.com/ both for GPU mining and ASIC minig with Antminer S7 (for BTC and other "Asic friendly" coins).

I'm found I'm found... when I started to mining eth ..share found was 187-172...and There was a strong odor of Power...The wire graphic was water that power..in this now 2 graphic to 1 the wire and 2 graphic other to 1 the wire I connected...The now my share found is 147 ms...so if I each graphic to a the wire power connected ..the my share found lower that 140 ms...

This Today was my experience that I said to you friend

Thanks that the read.

[jenci]

The now my share found is 147 ms...

share isn't found 147 or 100 or 3000ms. founded share _accepted_ by server after 147 ms!

Whats wrong with dwarfpool?

I am getting error message after every 1 hour saying "Cannot find job for 10 minutes there is something wrong in the Pool"

Any one getting same error?

Also lots of rejected shares

I'm running into an issue with Zcash Claymore's miner, I have 4 new rigs of 6x RX470 4gb Ref with the exact same parts and the same problem on each of them.

The GPU#0 is running at 40 hashrate and the other 5 is running at 205 hashrate... Where is this problem coming from ?

[omshree]

Display or dummy plug to the mentioned cards.

You can connect a monitor to the one that works at 40, sometimes i have this problem and plug a monitor resolve that

This line concerns me:
GPU0 t=68C fan=82%, GPU1 t=52C fan=16%
I have 2 GPU's running: 2x HD 7950

GPU1 seems to be acting lazy. How comes that the fan is only at 16% and t = 52C? It seems to me like the card is not performing as it should. Is this behavior normal?

There does not seem to be any ouput  about the amount of sols. Is there a way I can calculate this looking at the amount of Hashes per second?

I'm concerned about the fanspeed of GPU 0 as well, it's about 87%. What is the normal fan speed while mining?

GPU 1 is giving you 172 sol/s, whiich is lower than GPU 0's 201.

have you attempted any clocking with the cards?  it may be worth checking with GPU-z or afterburner what clock/memory settings the cards are using.

as for the fan usage have you set a -tt figure in the batch file? the lower you set the temperature the harder the fans have to work

I have not tried overclocking the cards myself. The cards are second hand. I installed GPU-z and found a difference in the memory settings of both cards:
http://imgur.com/a/X4r6T


The first card is at a CPU clock of 900, while the second one is at a CPU clock of 1000.
So If I change the CPU clock, I will get better performance, is this correct? Guess I'll start looking around of how this can be done.

I did not set a -tt in the batch file. I did specify however the miner should stop if the cards get over 80 degrees.

Awesome! it has solved my problem ! Thank you very much!
Can you send me a private message with your BTC adress, I'll send you a little something because you helped me a lot with that answer, it's very appreciated.

Hi Friends!

Can You advise me- what better to buy to have more H/s in minnig ZEC and spend less electricity?

Which card(s) is more profitable for minning ?

two rx470 4GB ram- 250$   or

two rx470 8GB ram- 304$  (do i need more RAM for mine ZEC or anything else?)

I agree with that. If you pay more than $0.12 per kWh, it is not profitable to mine the ZEC, let alone ROI.
