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

[crazymad]

Claymore: I fully support your idea of encrypted communication between your miner and mining pools. I don't understand people seeing some kind of evil in that. I prefer my mining stay as much anonymous as possible - that's the 1st idea for crypto currencies and especially for Zcash.. Pitty is that it can still be identified according to target IP/port.. Some kind of decentralization here would be nice as well :-)

anyway question for you - how do you handle SSL certificates? Are they hard-coded in your miner, does it download the certificate with the 1st connection and then compare if it didn't change? Otherwise it will be vulnerable to man-in-the-middle attack very easily.

Thank you for all your work, I don't have a problem with fee 2.5% for SSL either. Honestly I'd rather pay 3% for SSL then 2.5% with not encrypted traffic. Just my 2 cents..

Dwarfpool is a good pool, but for zcash a small pool. 18 blocks found in the last 24hours. A small pool could be unlucky and your payouts will be small. What matters in the end is not the statistics on the server, but what you get payed in the end..

In the long run.

Actually, Dwarf came too late. 24 hours ago its hash rate was around 1,000,000 and it found ~10 blocks/24h. Now it already is 1,599,004 (1.6 times increase) and 18 blocks/24h. If more people switch, the more blocks will be found per 24h.

So for me using high diff port is good choice right ?

If you have low share losses, then it should be good. But vardiff works well and adopts difficulty to hashrate of your rigs. So I would not bother if have less then 0.5% lost shares and use 3333 port.

0 share loses for last ~2 hrs on port 3337

What kind of hashes should I except with r9 270x 2gb?

This are actualy prety good..  135 - 140 sols - v9.1. Good ratio w/sol.. Specialy if undervolted

Thanks.

I'll have a place to run my rigs again later this year and thinking if ETH or Zcash is more profitable nowadays?

Zcash still more profitable today. You can main and accumulate coins and sold for 0.075 BTC later. Wait not long to such movements, it happen once every 2 weeks.

3.4% of total network hashrate is not so small hashrate actually - and it is growing.  Even with high variance +10-20% more than Flypool it is more profitable.   The reason it is small now - unfortunately it was launched quite late after ZCash started.  But not a problem to get hashrate from smart miners.

Flypool


Dwarfpool, the same hardware +900 H/s (+15%)

It does not start dwarf pool where my mistake in start.bat? Thank you

ZecMiner64.exe -zpool zec-eu1.dwarfpool.com:3333 -zwal wallet_adress.1 -zpsw x -i 8

[gaah]

Any news Claymore?

[d57heinz]

I'm also getting more at dwarf. much better that fly pool.

it's definitely v9-9.1 issue with regards to spikes & instability.

let's see if next version fixes it.

I switched 1/5 of all my rigs lets see what happens,
also I'm confused about different difficulties on dwarfpool
Main-Port (vardiff): 3333
Stratum-Port (diff=8): 3334 for CPU
Stratum-Port (diff=128): 3335 for videocards
Stratum-Port (diff=512): 3336 for rigs
Stratum-Port (diff=1024): 3337 for big rigs

3333 works fine.
BTW Dwarfpool shows actual hashrate and it is almost 10% higher than Flypool.
Dwarf also the honest one for long time on ETH.

At first I seen a major discrepancy on dwarf from what I should have gotten pd. Since then it has been fixed. I have yet to leave dwarf since day after they started.  I'll show some stats once I get moving today. I'm really happy with them so far.

version 9 better than 9.1 in terms of spike power
testing your rig (use chrome open(use shortcut on taskbar) & close (use alt+f4) repeat it until power spike come and yur rig will shutdown)
 


claymore need to fix this, lol

can't wait till the next version maybe it will be corrected

lol. not sure about 9.1 or your testing methods, but yes gpu core spikes from 73 to 110+ on my 470 refs (doing 200+ on stock with -20ish offsets and 1500stripes)  and hardcoded volts (more UV) spike from 60ish to 90+
which all doesn't look too healthy...

Hi friends!

tell me please: is it still profitable to mine zec?

While mining my asus r390x has 85 degree celsius! Wondering how many watts it took for month ?

have only 300H/s ... about 48$ per month

How long(months) can live Asus r390x (it has price 495$) with 85 degree celsius?

Will I take any profit per Year with current zec price?

not sure... but possibility to lost video card very high...

Please, advice me

Cheers

Hello! Underclock your GPU, or make a better cooling ASAP or you have a risk to burn your chips (you will see less clocks in future)

Thank You very much for advice!

Added more samples to OP for encrypted connection:

miningpoolhub SSL/TLS connection (this pool detects encryption automatically so it uses same port as for unencrypted connection):
   ZecMiner64.exe -zpool ssl://us-east.equihash-hub.miningpoolhub.com:20570 -zwal YourLogin.YourWorkerName -zpsw YourWorkerPassword

 coinmine SSL/TLS connection:
   ZecMiner64.exe -zpool ssl://zec.coinmine.pl:7017 -zwal YourLogin.YourWorkerName -zpsw YourWorkerPassword

mine reaches 94 degrees still going strong though. will try to change the thermal paste.

Such cards consume about 300 watts per hour. Normal operating temperature up to 90 degrees, but I would not advise you to keep it more than 80 degrees. I have a card that worked for about 3 years in a more complex operation, and they are still alive. Some have trouble with fan, but I had no such problems.

Set the below mentioned parameters in config.txt (or in start.bat, depending on what you use for config your miner)

-tt 65
-ttli 80
-tstop 90
-fanmin 50

(Or you can choose other values, these are just recommendations.)

Did you overclock your 390X?

What destroys the silicone structure is changes from hot to cold and back and the faster you go the worse it gets. Same goes for the other components.

[Ursul0]

To all those asking about profitability of coins: go to http://whattomine.com/ GPU section, choose 6 of 480 / 6 of 380, select all protocols and click calculate. Compare.
Their numbers are good.

EDIT: I'd say if you have rx400 ETH is the best now, if you have older cards with UV maybe zec (depending on your power costs)

Dwarfpool pump was succesfull!
2.7 Mh/s, it was 1.5 Mh/s day ago!
Great plus one for Moscow server, 20ms latency now.
