It is an independent rewrite from scratch. There IS a license coming along with the miner. Of course you have read it before using it.
Thatās just variance in Sol/s. Note the I/s is mostly the same.On each iteration the miner finds a random number of solutions, this can be 0, 1ā¦ or maybe 5. On average it is about 1.88. When comparing performance, either compare the longer average (at least 1m) or compare I/s as this has much lower variance.

iāll ask you here, already sent an pm, but w/o answer. Can you implement extranonce.subscribe into your miner? 
Without it, miner just disconnects from nicehash pool and start mining again like newly connected (rate drops, diff drops), with this options it just should change a job. i understand it so.
Is there an official Windows build for SA5 ?
not officialā¦ yet
there is the dagf2101 fork, and there is one other by someone else, forget the sanme zawawa or something id have to check
with my i7 rig i was getting about the same as I got in linux
545-550 Sols/s on 7 470ās
where in linux I got 550-560 Sols/s
on ym G3258 rig with 480s the difference was greater
and on my G1840 rig even greater
so just have to wait for the SA team to work the windows developments into their miner with optimizations which people are working on now
Adding extranonce subscription is on my TODO list.

It should work on any pool zcash stratum pool. Miner currently does not implement extranonce subscription, so will not work well with nicehash though.
Wow you are making $1200+ per day. This is the true mining 
And accepted, by claymore, challenge is also in todo?
Of course thatās possible and likely happens often. The primary benefits to reusing others code are that it allows a developer to focus on what they do best and release sooner while letting the original developers improve and debug the shared code. Rewriting open source code that is already working just to avoid license terms often creates headaches in support and is seen as short-sighted. At least thatās how I and most of my colleagues view things.
You are right. I did not read the license as I was running a canary test, which it failed. If it had worked out, I would have done full review before putting on any machines I really care about. As a hobbyist since the early BTC days I donāt run a commercial farm so my pace for adoption is not as critical as many here.
I disagree with bit of that. Most of the nix āusersā on here simply follow guides and have no idea how the OS works or remotely how to troubleshoot it. At least with Windows you can fix stuff when it breaks without needing to know exact CLI commands. You can fumble around and try and get things working. Nix is a very unforgiving OS, which is why there are people who are certified to work in it and receive the paygrade. Itās literally programming. Of course it appeals to programmersā¦
windows users ask for help all the time too, when people are learning, they usually ask for help.
but, IMHO windows users are far far more demanding. people who try linux are not as demandingā¦ if something doesnāt work for them they accept itā¦
though there are some linux users in here (this thread) that are also very demanding, so again, one size does not fit all
the question that I really have is can the windows only users actually even install windows themselvesā¦ or are they the kind of users who take their PC to a shop to get windows installedā¦ just a curiosityā¦ i would like to see statistics on itā¦
I have dual boot on my rigs so I donāt care, I just go where the profit is. But the problem with mining on Linux with AMD cards is not whether Linux is bad or good against Windows - I donāt even want to start this - the problem is that AMD doesnāt care to support Linux. And since there is no voltage control in Linux, you still have to atiflash your cards under Windows and pray that it wonāt crash with modded BIOS. And when it finally crashes - go figure whether itās overclocking, undervolting or just some newborn buggy miner.
Iāve been babysitting my rigs 24/7 since 28th of October switching OS, miners, pools, forks etc on a daily basis. Thatās pain in the ass to troubleshoot it all when everything: crypto, miners, pools are all in alpha stage. But thatās fun, however, in some twisted geeky sense.

There is voltage controll for AMD cards in Linux.
There is just no tools for small mining farm owner to do it.
So Iāve heard you can run this miner under windows using cygwin!?
Iāve tried, but getting this error:
optiminer-zcash: cannot execute binary file: Exec format error
Anybody knows how to fix it? I did set path under env. var.
I havenāt found anywhere a description of undervolting RX series under Linux in software. Did I search not good enough or are talking about some proprietary hacks?
They accept that something is broken and give up or just move back to Windows? Why would you use a broken OS?
Sure, you have to learn on both sides. Itās just far, far easier to learn Windows then Nix, specifically because you need to know exact CLI commands and arguments to fix anything. When Nix breaks, you have to google and hopefully find a answer orā¦ just give up. Giving up isnāt a answer when itās your job. You have to find a solution that works, which means going back to Windows or hopefully finding a google result that gives you what you want (or help on a forum).
Most of what nix users here are demanding is already available in windowsā¦ You know how often fan speed control, overclocking management, and advanced device monitoring is asked for? It is in every miner thread because nix doesnāt have it. I know of at least a half a dozen windows apps off the cuff that can do just that.
I really just think nix is a OS that appeals to a lot of developers because they are developers and nix offers a lot of control over everything you do. So much so that itās actually detrimental when something breaks and you have to figure out what to fix. Itās a programming OS for programmers, for everyone else itās a huge PITA to use.
@Optiminer So are you going to provide details of what your dev fee you included as many saying 15% is this true or not? What actual fee have you put on this if it really is 15% why so high and for making bigger speeds for everyone to use theirs no real advantage to use as the dev fees if 15% or so is just gonna be pointless to even use with such fees. I understand about donating and having a def fee but that is just daylight robbery if 15% CMO. How long does your cut stay mining like in terms of sec mining for x amount of time over a day? If 15% daily than that is a total rip off. Also you going to make a Windows build?
I havenāt found anywhere a description of undervolting RX series under Linux in software. Did I search not good enough or are talking about some proprietary hacks?
You searched good enough. No such tool was released to public.
I however know two persons who have such a tool: Wolf0 and myself.
There are probably others.
If it is āsome proprietary hacksā is a matter of perspective.
If you know how to parse bios of RX series you can rewrite voltage info under Linux using amdgpupro.
