ethminer-0.9.41-genoil-1.1

[Genoil]

For 1.1.3, go to cpp-ethereum directory and type git checkout 110. Then re-run cmake & make.

[adamvp]

For 1.1.3, go to cpp-ethereum directory and type git checkout 110. Then re-run cmake & make.

still the same:

should I add it after cd cpp-ethereum/:

Code:

git clone https://github.com/Genoil/cpp-ethereum/
cd cpp-ethereum/
 HERE (git checkout 110)

mkdir build
cd build
cmake -DBUNDLE=miner ..
make -j8

or its maybe related to something else:

Code:

or cmake earlier ??

So why it doesn't work?

First you might want to be in your home directory
run a "pwd" to make sure you are in home directory
if your not there run "cd /home/username"
then do a "ls -al"
if cpp-ethereum is in your home directory just do a "sudo rm -rf cpp-ethereum" to remove the cpp-ethereum folder and all files in it as we will just start form scratch.

Code:

sudo apt-get update
sudo apt-get -y install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install git cmake libcryptopp-dev libleveldb-dev libjsoncpp-dev libjson-rpc-cpp-dev libboost-all-dev libgmp-dev libreadline-dev libcurl4-gnutls-dev ocl-icd-libopencl1 opencl-headers mesa-common-dev libmicrohttpd-dev build-essential -y
git clone https://github.com/Genoil/cpp-ethereum/
cd cpp-ethereum/
git checkout 110
mkdir build
cd build
cmake -DBUNDLE=miner ..
make -j8
cd /usr/bin
sudo rm ethminer
sudo ln -s /home/username/cpp-ethereum/build/ethminer/ethminer ethminer

type ethminer -V -G now to see if its version 110.
It should report "ethminer version 0.9.41-genoil-1.1"

If that don't work, you probably did something wrong.

[sanadas]

it has certainly to do with the dag size, since it is smaller on the other coin, for old gpu with 2gb, that is an increase in the hash, as a result

so it's not actually more hash, it's just the original hashrate returning back on those smaller dag size coins...

If you mean Genoil's miner vs the stock miner, it is slightly faster.

I heard that you have a private Ethereum miner which has 7% more hash rate than the stock miner, is that true?

It's about 5-6% currently, but I'm working on a major overhaul that should increase it quite a bit, but it's painstaking and takes FOREVER.

That is very good. Does it consume more power? How about the efficiency? Is that better than the CDM?

Haha..  Thanks...  I am linux newbie and
I had tried re-clone to another directory..  I have to try when I  come back home.. 

What  about Crowdfunding for  Wolf to release his private  mode and maybe for both with Genoil  if they would  like  to  cooperate?

[Integ]

Genoil, is it possible to start mining on the latest build on 4X7870 or need a special version with separation of DAG?

If it doesn't start, add -L sequential to Cmd line and try again. Needs version 1.1.3

it is working but used memory is the same 1500 MB for each card...

on 6970 this method does not work ... 

[adamvp]

It works!  Although it  was some errors while following your steps

With llvm for example


And my hashrate is lower than with  CDM 18.8 vs 19.7mhs one 380x card..

[davembg]

Is the stratum mining logic seperated from the getwork one?

No, only the protocol - see https://github.com/Genoil/cpp-ethereum/blob/master/libstratum/EthStratumClient.cpp

The nonce generation appears to be modular.

@Genoil - is the hashrate ever submitted when connecting via stratum?
If not, can it be added to happen right after mining.submit? - seems like a logical place to me.

[Genoil]

No it's not part of the stratum spec.

Note that there are currently two stratum clients; async and sync (V2). The latter is much more straightforward and works just as good.

Genoil, as it turned out , -L sequential is not needed on system with the 7870, as it`s not necessary to change system variables.
To work enough version 1.1.3 only...
But the 6970, seems like nothing can help...

Will you add it if I code it?

Pools need to support it.

Of course, Donkeypool.com will support it:)

I trying to compile Ethminer on friend's rig..
First error is:

Code:

wget -O - http://llvm.org/apt/llvm-snapshot.gpg.key | sudo apt-key add -

Code:

2016-06-10 16:52:28 BŁĄD 404: Not Found.

How to fix it?

[crazyearner]

Epoch Switch: seems it keeps braking on one system when the restart happens yet on my main windows 8.1 system updates find and miner does not crash. How to fix on windows 7 system as when Epoch Switch resets or restarts miner stops working and does not re adjust. How to work this and stop from crashing at point of Epoch restart or reset?

[jjjordan]

I was just about to say the same thing.
On epoch switch some miners get stuck and a kill process is required.
Windows7x64 And I suspect the machines with the older drivers (pre R9 3xx - 14.7?! or something) do that.
Haven't done any investigating though.

[bensam1231]

Yup... When a new dag is generated the miner freezes. Was trying to figure out WTF was happening. Quite confusing.

Also it seems like 1.1.3 isn't as stable and hashes about 5% slower compared to 1.0.8.

[PeaMine]

I notice when using ethminer on Windows 7, opencl, AMD 290X that the global overdrive settings for the Fan don't seem to work.
Is this hard coded to override in ethminer?  How can I increase the fan speed (currently on 55%, which isn't bad, but wanting to turn it up)
Also I'm getting 24MH, is that bad?  Can I tweak things to go higher?

[Genoil]

For added stability during dag generation, add -L sequential to the command line. This is only useful if you have multiple GPUs.

You may also add -SV 2 to the command line for alternative stratum client.

I doubt 1.1 series is really slower than 1.0.8. Personally I feel it is a little bit faster.

What does "-L" do exactly? is it the same as "-T" ? for multiple gpus
