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

[Tmdz]

I guess, most peepz is now dumping, the price still falling reaches 0.74BTC as of the moment. and difficulty is also increasing. effect of claymore's Best miner :-)

Yeah, I really do not know why people are so happy. Here is the effect of CZM (this miner): profitability dropped by 2. In fact this is the end of profits on ZEC. Maybe it is good for decentralization, but it is an absolute evil for those who wanted (and made) some money on this. Let me explain in some bogus numbers if you like.

Assume there were 3 players that generated 200, 300, 500 shares for 100 coins/day (10 shares per coin), they received 20 (200/10), 30 (300/10), 50 (500/10) ZEC coins. Assume 1 ZEC = 1 BTC. And they received 20, 30, 50 BTC/day.

Now they have doubled hash rate and generate 400, 600 and 1000 shares. Since number of coins per day is the same (difficulty jump up to ensure it), now we need 20 shares per coin. They still create 100 coins/day and should receive 20 (400/20), 30 (600/20), 50 (1000/20) coins. The same amount, but increased power consumption.

But now some lazy newbies started mining ZEC as well, and lot of old cards are now mining too. Let assume they added +20% of total shares. That is we decrease the ZEC profit by 20% and now receive 16, 24, 40 + new 20 percent of share for same 100 coins/day.

Also we all are rich now and start dumping. The price dropped by 25%, and now in BTC we have 20% less. If 1 ZEC was = 1 BTC, now it is 0.75 BTC, and instead of original 20, 30, 50 BTC/day we and newbies receive 12 (16*0.75), 18 (24*0.75), 30 (40*0.75) and 15 (20*0.75) BTC.

Was: 20, 30, 50
Now: 12, 18, 30  and 15 for new players who was waiting for this miner.

And yes, you should also subtract 2.5% fee from this amount.

Net result: 50% real profit loss. Numbers are not real, but the idea is the same. Do not know why people are so happy. I think only those who was not able to build a miner on Linux are now happy since they have come into the game. But good profitability is behind.

This is the unfortunate truth.

Genoils miner kept a certain amount of people off zcash with the crashes but those smart enough had a watch dog script that keep it running or use linux.

But this is the reality we have to deal with now, a increasing hash rate, decreasing price on the market.  The last redeeming hope is that we will Still increase the block reward by 4x as it is now ~2.5 to 10.  So as long as the market does not dump to or below $125 a coin we will still be in a good position.

Also at least we were smart enough to know that cloud mining was a total waste of money, those are the real losers here.  With the biggest profit leaders being cloud mining providers and private miner devs.

In this logic, the only ones mining would be the big farms. And this applies to any coin, not only ZEC. You are wrong! Unless you have a big farm and want to keep ZEC mining restricted to a few big players.

Genoil and Claymore are giving a chance for the domestic miner to make some profit, and that's a good thing!

[osnwt]

The flaw with all your logic is that linux users have been seeing these speeds almost a week ago, the playfeild was not level , at some point windows users would have switched to linux and it would be the same net effect.

Linux users (including me) have seen almost this not with 7970@46Sol/s. 290/390 - maybe, 4xx - maybe. And imagine how many 7950 cards were waiting... Also many people did not mine ZEC yet. There were reports on ZEC forums that they switch as soon as decent miner will be created.

Not only big players. Everyone could install linux, build silentarmy miner using clear instructions and run it home.  But not everyone tried to do so. That is the key. That encouraged to learn something new. Now it is as simple as download and run.

As for the chance, 1-2 days ago my small farm at home gave me $125/day with silentarmy what was rock solid for me. Today it is $50 even with CZM. No speculations, plain fact.

[Hotmetal]

Half of my rigs crashed during the night while the automatic reboot didn't even work.
6 GPU rig of RX480 seems very unstable with claymore. It almost never happened with genoil ZEC miner.

I guess I must look into lowering voltage and clocks. They were all stock settings btw.

Why use Genoil when you can use Silent Army v3?

That's true 

But my small farm 1-2 days ago was crashing with Genoil's and now is working at full steam with Claymore's!

My profits increased! At least for the next couple days....

Soon, it will be time to consider the return to ETH

Stock BIOS is best to use with 4XX cards here.  Actually got better speeds when flashing back to stock from my ETH mod BIOS.

[randywald]

Can't complain. If someone codes a good miner, it will only take a few days until everyone uses the most profitable miner. So the profit lasts only for a few days. But also stability is one thing that is needed for profit. Older cards with 1-2 GB now also have a good hashrate. That means it is friendly for the home miner with older cards. Edit: Mining farms always replace their cards for the newest to get the best performance/watt ratio. Maybe that means that the other miners get 10% less because of the higher total hash rate, but there is nothing to complain about.

Price going down is normal in my opinion, as the supply rises. Price will stabilize at the end of the slow-start-period i think.

I have around 60-65~ Sol's with my computer.

For now just 1 470 4gb nitro 42-48~ with claymore

and a 6600k 18-19~ with nicehash

running both together stable.

Will get 24 GPU's soon... letz see how it will roll then

I get from 80-100 H/s with Genoil.

I can not get this miner to work at all with Suprnova!

Code:

ZecMiner64.exe -zpool zec.suprnova.cc:2142 -zwal <miner.name> -zpsw <password> -allpools 1

This miner seems completely broken and started losing me money.  I get 0 H/s on Suprnova with this miner.

It's because you use -allpools 1, there is a bug, after the devfee, it won't restart mining = 0 H/S

Wait till bugfix or mine zcash directly.

Claymore will probably fix it today.

I have no problems at all and i am using -allpools 1
Mining at Nicehash

[z0n0]

Is there something like this, but for ZEC?

https://etherscan.io/charts/difficulty

[Claymore]

In a few hours I will release new version with bug fixes, also "-allpools 1" won't be necessary anymore for all large pools.

[z0n0]

I have around 60-65~ Sol's with my computer.

For now just 1 470 4gb nitro 42-48~ with claymore

and a 6600k 18-19~ with nicehash

running both together stable.

Will get 24 GPU's soon... letz see how it will roll then

Is that with all 4 cores?
Strange, I get ~25 with my 6500

if using flypool, do we need the "-allpools 1" ?

just saw Claymore's post on this matter,

can miners post their reject %?

It seems in the first few minutes of mining, quite frequent rejected shares....

[Trimegistus]

https://etherscan.io/charts/difficulty

Yes, something similar:

[Claymore]

For any pool: start miner WITHOUT "-allpools 1". If miner complains and doesn't want to start, add "-allpools 1".

[citronick]

In a few hours I will release new version with bug fixes, also "-allpools 1" won't be necessary anymore for all large pools.

btw, Claymore, are you also looking into the rejected shares matter, seems in the first few minutes frequent occurrence of reject shares.

I average about 10% rejected shares at flypool.org with 3kH/s mining.

Thank you.

Can you please let me know if the 470 and 480 cards have room to grow in regards to sol/s?

miningpoolhub, 10 hours in work, 7970x4, 0% rejected shares.

[snakey]

I finally got my miner working.....

Would be great if someone can provide the best settings for rx470 cards please?

Also I am getting around (300ms) can someone please help to bring that down?

[Gpumanijak]

Wtf shit of program made by claymore r9 280x same speed as rx 480 and close to r9 390 = VERY GOOD OPTIMIZED!! LOL
