Miner- Optiminer/Zcash GPU miner v1.7!

well I really like arch manjaro over windows personally
what others do is really none of my business or concern
i have no need to argue windows vs linux… buddy above said its like a fanboy thing and then people want to keep arguing it one way or the other… its not debatable IMHO,… windows is better for some things linux is better for others… for the average user who just surfs the internet anyway, linux is probably better…

for gamers, windows is probably better, though steam is in linux now also, comes preinstalled in manjaro
for miners - its really a toss up imho… linux has some benefits that windows doesn’t … windows has some benefits that linux doesnt… personally if I can get the same speeds in both im going to run it in linux… but you do what you want I dont care what you do.

anyway im taking today off, I need to catch up on other stuff that i have been putting aside

like I said both offer benefits over the other. windows can be easier for somethings and linux can be easier for somethings… but in the end im not going to cry and complain that there is no windows miner when I can use it in linux. i really dont linux users crying and complaining that there is no linux version of this or that miner… but I see windows users crying in every linux thread… whats with that? anyway no need to answer, this thread is not about windows vs linux, its about optiminer and i probably wont get to test it out until tonight or tomorrow already

The Dev fee is at least 15%, this is fact from counting submitted shares.

I call it a job well done fee and he deserves every bit of it.

Interesting. You are complaining about a potentially high dev fee but still demanding a Windows build? You really think you can get everything for free no? When did you last donate to an open source dev?

So 164 replies and nobody mining with a R9 280X? What speeds?

@Optiminer have you tested your opencl kernel on NV?

R9 280X stock:
130 Sol/s

What do you mean with NV? Nvidia? I do not have any nvidia cards at the moment. But who knows, the dev fee might inspire me to buy one.

yeah Nvidia, shame you have none, they are better at least for gaming :slight_smile:

Tried optiminer/zcash using https://simplemining.net and it was up and running in under a few minutes. Just need a usb stick and simpleminer provides a web gui control over the ubuntu session remotely that spawns whatever miner you configure in the web gui. very cool!

I get an error "GPU Fault Detected: 147 0x09f8c401 in between successful bursts of shares being mined and submitted. Any thoughts? I didnt encounter any issues with claymore 4.0 on windows 7, exact same hardware. odd?

3 x RX 480s

Config for simpleminer:

Thanks for reporting! You can safely ignore the protection faults. They should not happen but do not affect mining.

Hi @Optiminer,

First, thanks for the great work. I’m happy to pay the fee for work well done.

I am a bit curious as to how it works:
I’m getting anywhere from 480-510 H/s as displayed on flypool. At some point for a certain amount of time will it switch over and mine just for your address or does it mix your fee into the current solutions? How does that work?

Thanks again!

While voltage control / fine-tuned clock control isn’t publicly available, for users with 4.8 kernel, you can pick your sclk lines fairly trivially: The Many Exciting Features To The Linux 4.8 Kernel - Phoronix Forums

Limiting myself to 012345, I can reduce my power usage by over 20% while reducing performance by only about 5%, which counts as a win in my book now that the bonanza is over, and efficiency is becoming more important again.

How dev fee works: In every second the miner spends some GPU time on working for the dev fee.

Thanks for confirming… another reason i ask is because after the first share submission from 4 GPUs all shares are accepted then every generation after that skips GPU2. Is there any way to get logging or details as to what happened to GPU2?


EDIT - I moved the cards around and put the “ignored” GPU directly on the motherboard instead of on a riser. Whatever rotated around seems to have resolved the issue because now I get shares from all 4 GPUs and i’m initially at 425 S/s! Incredible! Going to let it run overnight and see what the pool reports. So far power consumption is also down, pulling ~520W at the plug.

Can you edit the package to suppress the GPU faulted detected from logging please?

Of couse you can.
You could force card into lower dpm state (which have some lower voltage).
You however could not change clocks for this state (without bios changes or hacks)
and could not reduce memory controller voltage (without hacks).
And for optimal perfomance per watt you want both.

So what I’m seeing in flypool is my takehome after the dev fee? Also, are those H/s spent on the fee displayed to the user as part of the total H/s? I just want to know what I’m seeing @Optiminer. I’m sure others are wondering as well… Thanks!

What you are seeing on the console/pool is your own portion of the hash rate, I call it your effective hash rate.

Excellent - thanks.

Do you know what the GPU … I/s … S/s (1s) … I/s … S/s (1m) … I/s … S/s (1h) means?

My guess is 1s == current, 1m == 1 minute average and 1h for 1 hour average. Sound about right? Not sure what the I/s means though.

I/s = iterations per second or Equihash runs per second.
Each run produces on average (for Equihash n=200, k=9) 1.87905 Solutions per second (Sol/s)

That works in 4.4 as well, at least on the Ubuntu 16.04 release I am testing with the amdgpu 16.40 drivers.
