The announced Zcash release date is just 18 days away and the community STILL does not have a GPU miner available.  There have been some projects developing an open source miner, reports of a few private miners, and there is even a miner that is auctioning off hash from their rigs running their private miner.

With ETH's eventual transition to POS, there are A LOT of miners looking seriously at Zcash (me being one of them).  I currently use Claymore's dual ETH/DCR miner and would definitely use a Zcash miner should he choose to release one.  The 2% fee he charges would be no problem and I think a lot of others agree.  It would ensure we get in the door early, reduce centralization (currently we have CPU miners pitted against privatized GPU mining software), and likely make Claymore beaucoup bucks.

Trying to get a gauge on how much of the mining community would use a Claymore Zcash miner for my own personal curiosity in addition to bringing it to Claymore's attention in the hopes to motivate him to begin work.

What do you all think?

There is a 30,000$ contest for an opensource GPU miner. many people are going to send their miners and I'm sure one of them is going to deliver a great product.

Claymore's miners are easy to use, well-designed and stable, but I still prefer an open source one.

That's a fair stance.  There are plenty of open source ETH miners available - but Claymore's still gets wide usage.  Why?  Because it is a superior product.  The only reason I see him sitting on his hands with a Zcash miner is because it will pull hash away from his ETH miner - that's understandable since he's put a lot of effort into the dual ETH miner and wants a return.  Just hoping he gets motivated to get on the Zcash train before too long!

$10k of that goes to the winning GPU miner, not all $30k

..and which platform will take advantage , AMD or NV

Hoping AMD since those are all I own.  But I suppose that is up to the miner code.

The prize is $10000 for each miner and it has to be open source. Good luck getting Claymore involved... ;D

zcoin too mr. claymore

it is still a cpu mineable coin....

and take a look at pascal coin too, there is already nvdia miner..we need amd miner.

Yep, but I have no problem with a dev fee.  Didn't bother me with ETH, won't bother me with Zcash!

prize $ & devfee, no happy, i vote for w0lf !

I wouldn't be surprised if Wolf already has a equihash miner  ;D

It would have to be open source to get the prize.  That is not likely for a dev fee miner.

He already commented, said he is waiting until its released first.

The real mining of that coin won't start until mid to end of November due to the low rewards ramp-up. So we have plenty of time.

I would definitely mine a few coins.
Zcash is interesting.
It has a lot of hype right now and its probably a good idea to get at least a few coins early.

The slow roll in rewards might not make it that big of a deal to get in early or not.  But the forced scarcity may create some great selling opportunities for early mined coin.  I'm wanting to get in from the start.

eh you can't have both, if it is open source, a fee will be useless

Don't know if I am explaining this well enough - of course Claymore would be closed source with a dev fee like his other miners.  He wouldn't qualify for the "Open Source miner contest" if he used his to-date business model.

I guess the real money these days is not with miners but miner developers.

I hope the zcash gpu miner is for nvidia .

yes but what would be the point in using it? if it is no faster than his own fee, or it's not adding dual mining...

That amount of $10,000 is too low for Claymore. I believe that he earned hundreds of thousands from his miners.

There are countless people who will compete for the development, he's not the god of miners.

The only person I've seen speak publicly is JW (Genoil), and he has said he gets minimal donations.  I suspect Claymore makes enough to live off from the dev fee.  Comments by Wolf suggests he is living off miner development income, but not making as much as a full-time software developer would make where he lives (somewhere in the US, I think).

Don't recall raising Claymore to deity status, perhaps I was drunk and forgot about that post...

The fact is, he has done well with ETH and XMR miners.  No reason to believe he wouldn't build a competitive / enhanced miner for equihash (Zcash) as well.  

As of now, there are no publicly available GPU miners for this algo.  So a 99% dev fee would be better than what is available..  

What I'm basically saying is that he doesn't have to make his own miner for us to have an awesome miner to use. Wolf0 has done well with his sgminer-gm as well, maybe a little more difficult to set up, a little less pretty but it does the job, and by investing 10 minutes of your time you can save the 1% you pay Claymore. exactly the same hashrates on Hawaii chips and an higher hashrate on my Fury X.

I don't have anything against him, he does have great miners and I have used them in the past. but I personally don't think we should use someone's closed source miner and pay him 1% of our earnings.

what about this zcash opencl miner?
https://github.com/slushpool/poclbm-zcash

You do realize that Zcash will bring more or less the exact same profitability as Ethereum does right now.

Only good thing is if the market cap is large enough then ETH difficulty curve might slow down.

What are you basing that assessment on?  It isn't even out yet... let alone listed on a market.

ETH will go POS eventually. ...

When the ETH or other ETC goes to PoS, the ZCash will in place of it and become the largest altcoin.

If you mine the ZCash before other people do and the difficulty is very low, you can make more profit.

The block reward is very little during launch, it will increase slowly, so there is no way you can make extra money by mining it early.

After a month or so it will settle off and most likely profitability will equal to that of ETH.

Look at what happened with XMR and its difficulty. It double/tripled in price and within hours miners started shifting their rigs. Same thing happened with LBRY, same thing happned with SIA.

This coin won't make any miners any richer, all it will do is dampen ETH difficulty for a short while. The people that will benefit from ZCash are the founders, investors, miner developers, cloud mining operation, and pools.

and miners with very cheap electricity and miners with free electricity (advantageous situation or stolen).

I would gladly pay a dev fee to have access to a gpu miner. The sooner the better.

I am not confident the slow rise will go as published.  Have seen time and time again where DIFF is gamed and the early blocks go much more quickly than anticipated.  Being in position to mine early is where I'd like to be. 

You do realize that you have all aready been beated to the punch by Genesis Mining.

You can check the Genesis Mining website and see they already have a GPU miner, and it has already been optimized with a 300% increase. Not saying it is in FACT true but IF it is true, then they will be, and already are, set up to destroy everybody in terms of hashing power.

This mining launch will be very, very one sided to the big dogs.... as usual.

You can still contribute to the crowd fund for open sourcing my solvers at

https://forum.z.cash/t/crowdfund-for-open-sourcing-tromps-solvers-funding-cuckoo-cycle/2465/29

Why aren't you joining the open source miner contest?

not true, it depend on how much the pump will be big, if you accumulate early and you are then lucky and a big pump appear it will be pretty much like etheruem, and big profit will be made

it depend on the hype, there is a possibility to have a higher profitability than etheruem for a short time, like 1 month or two, like it happened with lbry

I don't really understand why we need another coin. I know that Zcash offers anonymous transactions, but DASH already does that, and I'm sure there are others out there that do too.

I also understand that decentralization is a big issue - When I first heard of Zcash I was reading that it was to be designed so that it would be mostly CPU mining, so anyone could mine it - but we are already seeing the race for a GPU miner and this coin isn't even out of it's testnet! That means that as someone already said, the beneficiaries of this coin will be it's developers, mining pools, etc. So we end up (again) with some very large mining pools and some cloud mining operations being the largest nodes on the network, and really centralizing it right?

I guess "currency competition" is supposed to be a good thing but when you have a situation where there are hundreds of different coins out there - what makes people want to design a new one? Do they truly think they can do better than what already exists or are they just cynically launching something that they know plenty of miners will try so it can be "pumped and dumped" and then disappear down to the bottom of the list on coinmarketcap.com?

I honestly hope that Zcash is great and it succeeds, etc - but I just wanted to be devil's advocate and ask the questions above.

The biggest reason to release a new coin is simple... MONEY!

This coin has a lot of support so far, but how that will translate to the market has yet to be seen and I hope it will grow huge and become a good coin to mine.  Mining is getting bad as far as profits are concerned, market prices are doing nothing to offset all this incredible growth by gpu farms.

I don't know if new money will come in to buy up this coin as it is being mined or if the money will come from eth holders and such to get in on this new hyped coin.  If the later then it will do nothing to help our profits

I did.

That is good. More information.

Crowdfund for open-sourcing tromp’s solvers / funding Cuckoo Cycle

https://forum.z.cash/t/crowdfund-for-open-sourcing-tromps-solvers-funding-cuckoo-cycle/2465

"I'm happy to open source my solvers in exchange for a 20% community contribution to the Cuckoo Cycle Bounty Fund, which will offer up to 100 BTC in bounties for disproving my claims of the Cuckoo Cycle proof-of-work being optimization free. See

https://github.com/tromp/cuckoo137

for details on the existing bounties. The remaining 80BTC, if claimed, will be at my personal expense. The fund allows for significantly raising the reward for a performance doubling from the current $500 to a much more enticing 10BTC, and will scale with the 2-logarithm of the actual improvement, so that a 1024x speedup (or memory reduction) can claim the maximum 10*10BTC payout.

The bounties would be guaranteed for at least 4 years, plenty of time to encourage some serious attacks on Cuckoo Cycle.

While you're all no doubt keen on supporting advances in crypto-currency research, you may also be curious to see some well optimized Equihash solvers, to which end I offer the following in return.

On a 4Ghz Intel Core i7, one of my CPU solvers reaches 2 Sol/s single-threaded, 4.3 Sol/s 4-threaded, and 6.7 Sol/s 8-threaded, while another solver reaches 5.14 Sol/GBs single threaded for peak memory.

On an Nvidia GTX980, my CUDA solver reaches 17.6 Sol/s.

Open sourcing these solvers will take place if donations reach 20 BTC by noon Oct 14 (with a possible one day extension if the goal looks within reach at that time). If the goal is not met then donations will be returned (unless you're happy to unconditionally support Cuckoo Cycle bounties).

There are multiple ways to make donations. The escrow options are detailed in cryptogoth's companion post at

Crowdfund contract for open sourcing GPU miners
Later tonight, I'll be uploading a contract to Ethereum mainnet to raise 20 BTC for open sourcing John Tromp's GPU miner, with a deadline of 14 October 2016 (in less than four days) at 12noon EDT (16:00 UTC). I'll do a test run through several accounts I own and any volunteers who happen to be awake, then I'll post the annotated transcript from the blockchain to explain how the contract works. The contract will accept contributions in ETH, and OgNasty will accept contributions in BTC. Both w…

Well yeah, that was the plan. But then

https://forum.z.cash/t/crowdfund-for-open-sourcing-tromps-solvers-funding-cuckoo-cycle/2465/76?u=tromp

So you have entered your code into the open source miner contest AND you are collecting BTC to release the code? 

How on Earth is there ANY benefit of donating to you to release your code?  Your code will be available to anyone since it has been entered into the contest?!?!  This makes no sense.

Please make your own thread on that topic, this thread is to see who is interested in Claymore making a Zc miner.

Read the topic. He refunded most of who donated.

I'll save myself the minutes and take your word for it.  Again, make a new thread if you want to discuss the open source contest or this donation whatever-it-is thing.

He did refund most of the donations. Some donators want him to keep the donation. It is very good of him.

- 9 day for zcash , and not exist gpu miner ( no amd , no nvidia ) , its very bad .

I think there always Exist Gpu Miner but not officially and they release it after Lunch !!!!!

Is there a wallet or a CPU miner for windows yet? I have never run linux and all 10 of my rigs are on windows 10. Link or advice would be awesome. Would love to get an early start with ZCASH.

no windows miner, linux only at the moment

I heard if you have windows 10 aniv you can run the bash thing within windows and accomplish the same thing check on the zcash forums

you don't need liniux if you have access to a newish windows 10 build

you can install a vm linux on windows and run the miner there. i did that when testing zcash mining.

I did install bash just after i posted a few hours ago. I am no linux guy but am going to try and set something up.

Pick your poison, there are some here:

https://zcashminers.org/submissions (https://zcashminers.org/submissions)

Four days until genesis.  Come on Claymore!!!

I'm not working on zcash miner currently, so please don't expect that I'll release it soon.
Though its PoW looks interesting for me and as soon as I have time I'll check if I can create faster miner.
I get a lot of requests for private miner, so I have to repeat it again: I don't have any private miners, if I create a miner I make it public.

That awesome to know you would consider it.

Zcash has a slow start from 0-full coin rewards over 100 days so there is no rush.

100 days??????

Dude its 30 days.

Yeah but people on here are saying slow start has been extended to 100 days.

Edit:  I can't find any official reference of an extension past the 34 days.

Its 5000 blocks or so.

I will almost guarantee that slow roll ends considerably sooner than they say it will. 

And.... the thread caught Claymore's eye!  Look forward to see what you come up with, you are a mining software pioneer!

yeah. go claymore!

Claymore rocks :)

yeps, no private miner, kudos to that but with the fees ...

you're already VERY rich (at least 5M USD in eth alone) claymore, prolly lower the built in devfees ?

just my 2 sats.

5M ? You sure about that


Daily miners reward is $300,000 * 30 days = 9,000,000 = 1% fee = $90,000 monthly

$90K is the most he can make if EVERYBODY mining ETH used his miner, most likely only 20% use his miner. So $10-20K a month. Not bad.

I have no clue how you got this number, but it's far, far from what I got from devfee from all miners ever.
Anyway, if you really think that I got 5M$, it seems reasonable that you must learn programming asap and get similar amount, it's easy! :)

If 1% of defvee is too much for you, there is a choice, just use some other miner and save some coins.
In fact, you won't see any additional profit even if I make devfee twice less, I doubt you can feel 0.5% difference in profit.
And lowering devfee just because you think that I earn "too much" is not a good reason for me.

personally i think claymore deserves more credit then he gets, he may only make 1% dev fee, but think of how much more profit people are because just because they can dual mine eth and dcr or whatever
claymore does quality work and deserves atleast 1% dev fee on any miner he makes, if you dont think he deserves the fees then develop your own miner lol

i use your eth miner because its easy and convenient and earns me money.

if you do a zcash miner my one percent -or whatever you chose- is gladly yours :)

Whether Claymore makes $100/month or $100k/month on his dev fees is a completely moot point.  If he provides a product that is better than most or all of the competition, then he is ahead of the curve and in a free market economy, those who are able to produce something that the majority of any segment prefer earn the right to be successful financially... plain and simple.

Furthermore, he is absolutely correct that 1% fee cannot even be felt by almost all miners, even more so if he were to cut that fee from 1% to .5%.  Do you realize what a minuscule amount that equates to?  If that small amount really makes that big a difference to you I submit that you shouldn't be into mining at all lol.

Bottom line is that Claymore's miners seem to provide better Hash-rates than all or most other miners.  So, logically speaking, nobody should have an issue with the 1% fee. I could make a case that 1% is actually too low in fact, since my hash-rates are 10-15% better with his miners.

I'm betting the number is lower than 20%, I know of ZERO larger pools or private farms that use the miner (due to them not dual mining cause of extra stress on GPU's etc.) and they represent over 80% of the network.

Not to mention that a large part of the community that mines with 2-5 GPU or so wouldn't even notice 5%. They value an easy to use miner that doesn't crash, is easy to install etc.

Mining developer fees.  Pool Fees.  Fees to convert coins from one to another.  Transaction fees to spend the coins.  Fees to the power company for running the hardware.  Fees to the people you buy the hardware from.  Fees to pay for space to hold the hardware (even if rent or mortgage).  Fees everywhere.

Nothing's free.  If you can build your own hardware and generate your own power, you might as well write your own miner and live fee-free!

I'm a small miner (340 MH) and happy to pay these fees because ROI is good, even after all the fees. 

I'd gladly go for a DEV-Fee supported closed-source ZCash miner that's profitable.  As long as Coins - Power is positive, and Coins/Power is > 4, then I'm pretty happy.

https://bitcointalk.org/index.php?topic=1660023.0

no fees !

no disrespect claymore, NOT a single doubt that you're a great programmer that made an awesome miner software that works wonderfully & you definitely deserve the fees, TOTALLY agree with your statement, if don't like it, then don't use it.

i might be wrong with the figures hence this public apology to you.

i even voted to pay the fee if you made a zcash miner. but i'm asking prolly you might want to consider lowering the fees a tad, ain't saying NO fees ! just a request to you to consider.

everything has fees, totally agreed.

Definitely going to check out that open source miner that was just released.  We have a benchmark speed to compare other options with, good news!

It's technically 20,000 blocks, which according to the 2.5 minute/block specification should take roughly 34 days. However, with the initial hash-rate projected to be very high, block generation times will probably be greatly condensed making the slow start last anywhere from 21-30 days.

5000 blocks * 2.5 minutes/block = 8.7 days
https://z.cash/blog/new-alpha-release-mining-slow-start.html

It was updated to 20'000 blocks in oct

https://z.cash/blog/slow-start-and-mining-ecosystem.html

Yep, a lot has changed over the course of the past year. A updated list of the finalized specifications was maintained here:  https://forum.z.cash/t/final-zcash-mining-specifications/355 (https://forum.z.cash/t/final-zcash-mining-specifications/355)  if anyone cares. ;)

Even less than 21-30. On testnet, when jtoomim bros tested their GPU setup, they found several blocks one after another in SECONDS, and that was with <5 GPUs, if I remember it correctly. When ZCash mainnet goes live, hashpower dropped on it will be incredible, so first THOUSANDS of blocks will be found very quickly, until difficulty adjusts. So, may be we'll have a week - max! - of "slow start". May be.

Doesn't difficulty adjust on every block?

It does. But there is some max value of "difficulty delta" between blocks, so it can't adjust "at once".

ETH is dead end, say Hallo! to ZCash - together we conquer the Moon

Yes, yes, yes, move all your ETH machines to ZCash ASAP. Please. Cant wait for the difficulty drop on ETH.

The difficulty of the Etheruem will rise exponnetially in the next few months due to a difficulty time bomb.

This is supposedly the difficulty formula, which means creating a block 4x faster than the 2.5 minute target would double the difficulty for the next block.
(next difficulty) = (last difficulty) x SQRT [ (150 seconds) / (last solve time)

If zcash doesn't flop and stay profitable,  the best optimizers in the world will make kernels for it. The only way for you to enjoy the boost is to pay a percentage fee, or a high buy in.

People are spending thousands of dollars on cloud mining, I expect the coin to do well.

I don't expect them to make money, but mining should be in a good spot again.

Even if only private farms have the most efficient kernels we will still enjoy higher profit on eth by the shift in mining power to Zcash.

Linux builds plz :(

FINAL zcash mining specifications
Feb 24
1 / 20
Feb 25
10d ago

notsofastFeb 2411
I'd like to use this thread as a net repository or collection for the discussion of ZEC's mining specifications, so it's easy to find and parse in advance of an official statement from Zooko and the development team.

Mining algorithm: As of Zcash alpha release v0.11.2.z294, resolved in Issue #2715 the Zcash mining algorithm will be Equihash (white paper here149), a new, memory-hard, proof-of-work mining algorithm based on the generalized Birthday Problem and Wagner's algorithm for it. Equihash was created by Alex Biryukov and Dmitry Khovratovich of the University of Luxembourg.

Block time spacing/target spacing: 2.5 minutes, with 12.5 ZEC reward per block. This is as per
github.com/zcash/zcash/issues/142#issuecomment-112935618.

However, to protect against instamining and accusations of miner collusion, the zcash team has decided not to apply the above rate of emission right from the genesis block. Instead, ZEC's emission will be subject to a slow start, where the emission curve will gradually ramp up to the full emission rate of 12.5 ZEC per block over the first 20,000 blocks. If there are further adjustments to the block spacing and reward, they will be in such a way that the following equation always remains true:

{# of slow start blocks} * {full block reward} = 250000

github.com/zcash/zcash/issues/762#issuecomment-213658623

Difficulty adjustment algorithm: Digishield V3, tweaked to use the following trailing-average difficulty window:

(next difficulty) = (last difficulty) x SQRT [ (150 seconds) / (last solve time)

(as per https://github.com/zcash/zcash/issues/147#issuecomment-2451409084)

Difficulty adjustment period in blocks: This approximates to every block, as per the above link.

Transaction fee structure: Still TBD via wallet implementations post-1.0 protocol release. Currently exploring a privacy-safe fee selection algorithm. (IE, this won't be a critical element of the 1.0 zerocash release, and can be decided by wallet implementations later.) Assume this is negligible, in that max fees aren't material to a young network and that 0 fees can still be set if a user desires.
github.com/zcash/zcash/issues/398#issuecomment-155587212

Starting reward in ZEC per block: 12.5 ZEC per 2.5-minute spacing. As per
github.com/zcash/zcash/issues/142#issuecomment-112935618

Division of each PoW block reward between miners and zcash team:
- 80% (10 ZEC) to miners, 20% (2.5 ZEC) to zcash team, from genesis block to first halving of the block reward (approximately four years later)
- 100% to miners thereafter
- transaction fees paid 100% to miners throughout
As stated by daira below.

Reward halving period: every ~4 years, as per Bitcoin
github.com/zcash/zcash/issues/142#issuecomment-112935618

Total eventual supply: 21,000,000 (21 million), as per Bitcoin
github.com/zcash/zcash/issues/142#issuecomment-112935618

I look forward to final corrections, if any.

How about an addition?  It's missing the equihash parameters; k=9, n=200.

you are a good man Claymore !!!

i noticed zcash mining gpu's are not as hot as other algos...i'm sure claymore would max out these damn gpus again  ;D

It's about time for Claymore to release an AMD ZEC miner (put 2.5% dev fee, who cares). The miners available until now are utter garbage. Fuck their miner challange and everything else because only useless crap has come out of it so far.

Today I tried existing miners, I don't like their stability and speed.
Ok, I will release first version of my ZCash miner very soon. AMD only, at least for now.

sounds great! i cant wait to try it :) you sir are a hero

Finally, you have a good amount of money to make with ZEC :)
Miner working with Windows or only Linux ?

Can't wait !!

Probably windows, claymore dont like linux  :P

Thank you i hope we will have soon one good miner  :D

Excellent news! Please, don't forget old cards like 7970/R9 280X. On current miners they are far behind new ones, while having same memory bandwidth. That's strange, they can be heavily optimized for sure.

We need a linux version too... pls!
And.. what kernell? SILENTARMY?

Isn't there enough choice for Linux out there? Most of the hashrate pointed at ZEC so far is Linux based. What is dearly missing is anything that works on Windows.

Well if you ask me, I'd say it's badly needed, and ready to take it if Claymore even takes off 20% fees. The mining setup of zCash has definitely become a pain... >:(

Not true. My plain r9 270 2gb makes more sol/s than my r9 380 gb (17 vs 14)

"New ones" are RX470/480.
And how did you get 17 sols from r9 270? What OS/driver/miner/overclock parameters? Everybody else get about 6 sols from it.

There is only ONE fully working Linux miner which can use multiple AMD cards at a time (mining rigs) and that miner is hardcoded/locked to one pool (coinsforall.io). There is another miner (Zogminer) currently in development.

On the Windows side there is way more choice.

That would be super cool!

thanks man :)

Excellent news, Thankyou :)

YEAH!! BURN my AMD's Claymore  8)

Great News and hope that miner, but this do it Works fine
Great Job claymore by the way!

With extremal silentarmy miner win 7 x64, 16.10 crimson

Really? Which ones? I don't see a single windows miner that works with AMD cards. I have seen only a couple experiments which crash either immediately or after a short time.

How soon can we expect a miner?

 :o
This is awesome news!

hopefully cross build for linux too like your dualminer  ;)

I think someone is ddosing bct forum servers for preventin g claymore's miner release.lol

i look forward to claymore miner - been using ethereum miner for ages and is rock solid

Ok I did some testing.. Eth is slow but hey it's some extra coins at only a cost of 2-3 Sol/s on my system.

ZCash mining 50 Sol/s
Eth mining 60 MH/s



With Dual mining 47-48 Sol/s  17 MH/s

Small hit with Sol/s but not bad and getting some mining power on Ethereum.  So once Claymore releases his optimized version I think we will definitely get better results as currently I have two applications running to do the same thing which will make some performance hit there.

Use genoil 4.1 or 4.2 and claymore miner;)

when i try this I get 0sol and 0h/s  ??? :-\

yea i think so too

lets see if it drops today

Come on with the good stuff Claymore!!!

claymore just joked when he said he is making a miner

Awesome!

so 3 days passed and no miner. maybe claymore will not release but mine himself?

still good - he deserves it.

Perfection takes time.

releasing claymore's zcash miner will tremendously increase his hashrate (coming from the "fee"), it is more beneficial to him if he release the miner rather than use it himself.

come on Claymore, save me from sleep deprivation with these unstable miners LOL

I know, have to restart every 10 minutes or so....

Put it on a loop using a BAT file.

Was reading about that in the forums, will check it out.

thanks.

Hi,
If you want you can use my simplemining.net OS which doest that resetting for you :)

It restarts miner if detects 2 states in mining console window.
- at least 3 lines of "stale shares" or "crashed "
- more than 8 "found shares" but less than 4 "accespted shares"

#!/bin/bash
export DISPLAY=:0
MINER=`cat /tmp/miner | grep "Stale share \| crashed" | wc -l`

    if [ $MINER -ge 3 ]
    then
    echo "Miner error, restarting miner"
    bash /root/start.sh
#    sudo dmesg -c
    fi

shares_found=`cat /tmp/miner | grep "found share" | wc -l`
shares_accepted=`cat /tmp/miner | grep "Share accepted" | wc -l`
echo $shares_found
    if [ $shares_found -gt 8 ] && [ $shares_accepted -lt 4 ]
    then
    echo "Miner error, restarting miner"
    bash /root/start.sh
#    sudo dmesg -c
    fi

What cards do you use? What is your system configuration and driver?

Windows 7 64 bit
Latest Crimson Drivers

R9 280x 3GB
RX 480 8GB
R9 380x 4GB

thanks for the heads up....i'm gonna have a nice loooong sleep later, just waiting for sleepiness to kick in again

zcashclient works for me, pretty stable on my 280x's run for hours and hours (to be safe i loop it at 2hrs), my .bat loops perfectly .. genoil miner for me is too unstable the program error (doesn't run after the loop) and the 0 sols errors kinda fucks up the looping processes.

i bet claymore was paid to not release this

that's a possibility..he was like the chuck norris of miner developers. the others made miners already and he was, like missing the action.

I have a batch file that reads this.

I than put this in my task scheduler to run this batch file every 10 minutes.  Damn it's doing really good. Not only that if you tell it to run even when not logged in the console window is hidden.  I than setup a trigger for startup and login.  This way if someone does reboot my system than it will start back up.

@Claymore, great to see you getting involved with ZCash!  It's relieving to have a miner on the horizon that doesn't require constant babysitting of rigs and/or bat files that restart the software every 10 minutes.  I've actually just gone back to mining ETH until a better miner comes out, gladly will pay a % to the dev, good news!!!!!!

Do you mind outlining your entire procedure with task scheduler ? I haven't used it in ages and would rather not reinvent the wheel. My genoil craps out every so often - but it's your setup that allows the miner to resume on reboot that I am particularly interested in.

Good prediction based on solid facts...  Changing your tune there adaseb?

Sure.

General Tab: Run whether user is logged on or not (note console will be hidden with this command)
Triggers: 2 different triggers.   One for System Startup and the other for Log on of any user
action: Start a program (point to batch file. make sure you have the start in point to that directory or batch file will not run)
Conditions: As long as any network connection is available
Settings: allow task to be run on demand; Run task as soon as possible, run a new instance in parallel (last one is important as batch has the kill command)

Looks like he dont want to release.....

Of course he wants to release, he'll be getting paid a fee from each miner the moment he releases it. (Which is fine, of course) He's losing a lot of money right now due to people having ditched ETH and his software to mine ZEC. Once he releases his ZEC client, he'll get most of those miners back and paying fees to him to use his software.

i think he got paid to NOT release it. it would be out already

Very much doubt that. He said a few days. We're still in that "few days" period.

Creating custom software takes time, and even devs require sleep.

True story there.  Also, they should be rewarded for their efforts - bring on the miner Claymore!!!  If your hashrate is 1/2 of what you are shooting for, you'll probably have the majority of miners running your software.

That is what I am doing now. It is too frustrating to do the GPU mining with the ZCash at the moment.

give it time genoil-zec will be one of the best, some one said next release increase speeds fixes more speed drops and one other thing and it won't be out as fast it looks like.

一直在期待..........

you must be doing something wrong, i havent had to babysit my rigs for a few days now. working stable with no real issues.

There really is nothing to do wrong.

The miner is unstable, I use a powershell script to keep it working.

genoil is unstable under win7/win8 both GPU and CPU. i can't wait claymore windows zec miner.

You won't need to wait much longer.  He is releasing it in a few hours!!!

when is claymore releasing? Cant wait  :o

few hours..

Yeah me neither, I get a few crashes here and there but it's very rare now. Also my rigs consume a lot less power with ZEC which is a real plus for me (0.23cts/kWh), I've ditched ETH for now, I'm mining around 0.04 ZECs a day atm.

Please discuss ZCash miner here now: https://bitcointalk.org/index.php?topic=1670733.0 (https://bitcointalk.org/index.php?topic=1670733.0)

Ok thanks .

Are you kidding me?
