[ANN][X11] X11/Darkcoin Gpu Miner - updated to use leaked binaries - even faster

[atp1916]

You guys sure this miner doesn't submit fake shares to offset the increase in hash-rate?

Because I have no idea how it mines 40-50% faster while using 10% more electricty.

Code refactoring can work wonders.  There is plenty of room to optimize AMD code to produce more hash at the same wattage.

Optimized Nvidia code is producing 2+ mhs @ 30w on a 750 Ti and 5.5mhs+ on 780 Tis @ ~250w.

AMD code is so unoptimized for x11 it's nearly criminal.  

Wow, you're getting that from the new miner? What about the old one, not the "40% faster"?
30w power consumption while mining 2+mh/s, seriously? How much is the gpu load?

No, that was toward the cuda ccminer in which 750 Ti's are pulling over 2mhs (near 3 i hear with latest build) @ 30w.

My point was that it should not come at all as a surprise that more hash was squeezed out in the same watt envelope with AMD hardware.

what am I doing wrong?

driver installed. AMD SDK installed.

config:

Code:

set PATH=%PATH%;./dlls
set TERMINFO=.\dlls\terminfo
set GPU_MAX_ALLOC_PERCENT=100
sgminer.exe -o stratum+tcp://stratum-us.trademybit.com:4440 -u XXXXX -p YYYYY  --kernel darkcoin -I 19 --lookup-gap 2 --thread-concurrency 21568 -w 256 -g 1 --gpu-powertune 20 --gpu-engine 1150 --gpu-memclock 1500

result:

result:

Error -4 means "there is a failure to allocate memory for buffer object". This either means your card doesn't have enough "local" memory on your GPU to run X11 (it needs at least 8Kbytes of local memory), or that you have memory problems on your GPU.

Have you deleted all the .bin files from the folder before running? Which gpu models are you using?

failover is not available in this miner. You can either alter the source code to fit your needs or look for alternative solutions that have been posted on previous comments in this thread.

had to switch to the girino version and back to BAMT 1.6.0.  Too much instability on the free version: I could not mine for more than 8 hours at a time even with intensity and engine clocks reduced on PiMP. All my cards are R9 270, and 270x with one HD6870 thrown in for laughs.

Is there a way to pimpupdate to the girino version?

I have installed https://github.com/lasybear/sph-sgminer_x11mod on all my rigs (7950, 7970, R9 280X and R9 270). All rigs with 7950, 7970 and R9 280x work perfectly, but rigs with R9 270 hangs out very often from 15 min to 2 hours. But if I set in config
"kernel" : "darkcoin" instead of "kernel" : "x11mod"
rigs work perfectly and stable, but hashrate is more low. Can you fix this?
I have use BAMT 1.3, 1.6.2 and PiMP 1.4.2.

Code:

wrong thread. My miner is the one on the first post, not the hack made by lasybear. you should check with him for fixes on his miner.

Is it normal to get "Stratum from Pool 0 requested work restart" very often?
Why do I get this, and is it a problem?

Would anybody mind sharing their GTX750 Ti config? I'm getting 1,7Mh/s with no tweaking.

edit. seems as the work restart-message is normal.

I am not sure about it, since i don't own an nvidia card, but i think that for NVidia GPUs you should try cudaminer and ccminer, since they are optimized for those boards. People report getting 2+Mh/s with ccminer on 750Ti GPUs.

girino, do you plan to release an update for x13 algo? I tried the other free version, but can't mine with it because the rig locks up after 8 hours requiring a hard reboot.  All my cards are 270 or 270x and I've seen others with the same card have the same instability issues with the free version.

[sata3ssd]

Just so you know this guy seems to have hard coded in a pool - you will mine for him 2% of the time. It does seem to increase hashrate slightly but the reported rate in the miner isn't correct

I was not in my plans. I am still working on improving x11 algo. But if there is enough people asking for it I can try a fast port of the x13 algo.

The hashrate reporting has been extensively tested by many users and beta-testers, and no one has yet reported any errors. Please specify in which situation you are having hashrate reported incorrectly (which coin and pool, and which miner parameters did you use) so i can test it and correct it.

Any bug reports are appreciated and encouraged, since they improve the quality of the software.

which coins use this algorithm? i see they call it "marucoin" algorithm in sph-sgminer, but is marucoin the first coin to use it or only the most famous coin?

There isnt alot of them out yet, I'm going for the OPEC coin launching in about an hour. Check it out...https://bitcointalk.org/index.php?topic=633593.0

[hashbrown9000]

I'm definitely seeing an increase in hashrate with my rigs. Verified ob the miner and on my pools. Also in for x13.
