Can anyone provide a working link please???

Thanks
can someone re-upload it, please ?

reupped for thos who need 6.5 cuda version

http://wikisend.com/download/235412/ethminer-0.9.41-genoil-1.0.5-cuda6.5.zip

im currently bit busy but i will check back and try to compile 1.0.7 when Genoil releases it

@excavate It's normal.

Genoil · April 2016

@Cubirez for now, you may want to try out by "107" branch to debug your 970 issue. It has OpenCL optimizations that make mining OpenCL with a 970 almost as fast as the CUDA kernel (about -0.5MH/s in P2 state). Unfortunately I haven't got much time to work on ethminer lately.

Cubirez · April 2016

@Genoil I'll give it a try during the week. Do the OpenCL optimizations also increase hashing performances on AMD cards?

Genoil · April 2016

@Cubirez no. The host checks for opencl platform and if it's nvidia, it replaces some standard math with inline PTX assembly, and it limits register usage to the optimum (either 72 or 63). The latter is a big deal. If only AMD had an opencl extension for that.

Thank you for reuploading the build for cuda 6.5, I was unsure if it would be so i switched from win10 to Ubuntu using the latest release now with 1xgtx970 and 1xgtx980. I still get better results from using Ubuntu, even with the 350.12 driver on win10.

thank you for re-uploading.
with the 347.52 driver i cannot squeeze the performance : http://cryptomining-blog.com/7341-how-to-squeeze-some-extra-performance-mining-ethereum-on-nvidia/

And if i use 350.12 i get errors in windows 10

L.E: Installed 350.12 over 347.52 and now works fine and i could make the squeeze performance settings.

Im having trouble building ethminer following dr_pra instructions

build completes but ethminer will not run/open.

not sure what to do from here. I am inexperienced with linux.

Genoil · April 2016

@cpixels it looks like you skipped the step in dr_pra's tut where you downloaded all required dependencies. No OpenCL, no pthread. Then again, I'm also pretty inexperienced with Linux. When things work, I know my way around, but when things fail, I'm often at a loss

Genoil · April 2016

Finally got to add failover support to the stratum implementation. It's in the 107 branch, please build and test. It does seem to work fine.

Example command lines:

two completely different servers:

-S eu.ethermine.org:4444 -O 0xeb9310b185455f863f526dab3d245809f6854b4d.GTX970 -FS coinotron.com:3344 -FO Genoil.home:home -U --cuda-grid-size 2048 -E bench -R D:\Ethereum\DAG --farm-recheck 2000 --farm-retries 0

failover on same platform can reuse account creds:

-S eu.ethermine.org:4444 -FS us1.ethermine.org:4444 -O 0xeb9310b185455f863f526dab3d245809f6854b4d.GTX970 -U --cuda-grid-size 2048 -E bench -R D:\Ethereum\DAG --farm-recheck 2000 --farm-retries 0

immediate exit per @miningpoolhub request:

-S eu.ethermine.org:4444 -FS exit -O 0xeb9310b185455f863f526dab3d245809f6854b4d.GTX970 -U --cuda-grid-size 2048 -E bench -R D:\Ethereum\DAG --farm-recheck 2000 --farm-retries 0

I kind of forgot what else I promised for 1.0.7. Seems dual eth/decred mining is the new thing

*) note that the eu ethpool addresses in these examples will result in a failover, as the address doesn't exist.

cpixels · April 2016

@Genoil thanks I'm tired, think i'll try tomorrow before i make any more mistakes

dlehenky · April 2016

@Genoil That's the one I've been waiting for (stratum f/o). I'll build it on Ubuntu and give it a spin! Thanks!

P.S. RE: new dual miner - Windows only, even though 40%+ of the miners run linux, especially the larger ones; doesn't work on all pools, yet. Takes an automatic cut, not that it isn't a reasonable amount. Looks interesting, if linux support comes along.

Marvell9 · April 2016

Whats decred you're saying you can mine eth and another algorithm at the same time? Where's the info on this
Thks

Were you able to build for linux? What were your commands?

dlehenky · April 2016

@BeneKiki No, haven't had time, yet. If you go the the FAQ on ethpool.org, there's a nice build description for @Genoil's ethminer.

Genoil · April 2016

I guess I finallly need to edit that Readme.md with build instructions. If only for marketing purposes if you know what I mean

dr_pra · April 2016

@Genoil feel free to use my build instructions for that purpose

dlehenky · April 2016

@dr_pra Not bad marketing for you, either, having folks visit the pool FAQ for the build instructions, then deciding to mine there.

Hopefully.

dr_pra · April 2016

Also once 1.0.7 is out of beta and stratum support is stable it will become our recommended miner as it is provides superior functionality to all other miners currently available.

I tried to build several times following the guide. But the built executable does not support -S parameter, so stratum mining is not possible. May I miss some libraries?

dlehenky · April 2016

@BeneKiki You have to turn on the stratum feature in the cmake build file or include the proper cmake command line '-D' option. I don't have the source here to reference, at the moment, so I can't tell you, exactly.

Genoil · April 2016

@dr_pra I was planning to use those indeed, thanks again

. I have about 30 hours on the clock with 1.0.7 against ethermine.org without any issues, but I can't tell for sure whether or nor it's stable. As long as the pool is stable, I guess it's fine. It is once something happens poolside that issues may occur.

If someone can build 1.0.7, please share it, i want to give it a try

How about including Linux binaries? Want to try but lazy to go through all the compiling bother.

Thanks! Your exact help would be appreciated. I have no idea how to turn stratum feature on or use the -D command line!

Looking good, i only have to report that miner its not reporting hashrate to pool ethpool.org, but Effective Hashrate its good
