New X11/Darkcoin AMD GPU Miner With 40%-50% Performance Increase

x11-sgminer-performance-increase

It seems that the OpenCL kernel for Darkcoin for sgminer has been optimized by a user called girino over at the Bitcointalk forum to bring some nice performance improvement in the hashrate when mining X11 crypto coins such as Darkcoin. Do note that you need to use a precompiled miner with no source code and there is a 2% developer fee on the mining (the miner is hardcoded to mine at another pool for the developer), but with 40-50% performance increase over the latest sgminer with support for DRK the 2% dev fee is acceptable. We have tested the new x11-sgminer on a Radeon R9 280x and and we are getting a boost from about 2-2.1 MHS to a little over 3.1 MHS with the new miner. The author has provided only compiled versions of the miner for both Windows as well as for Linux, but has breached the sgminer GPL license by not publishing the source of the miner! So we recommend to download the already available fork by lasybear with the same kernel that provides the same higher performance, but also has the source of the sgminer available and no forced fee.

Get the new open source sph-sgminer_x11mode with performance increase for X11 crypto mining instead…

Hidden code to mine another pool.. Be careful!

Isn’t this in breach of the GPL (General Public License) licensing agreement ? Be very careful with this pre-compiled software, with no source code being available, there could be a lot of nasties included in it.

Just “Pool” – “Change management strategy” – 0
Or set quota of your pool to 999.

3070 kH/s with R9 280X @1130 core (mem 1500 Hynix). Temp 59-62 Celsius (25 ambient).

3070 with 280x? Can you post your configuration of sgminer please?

He is a scammer.
1. this is NOT his code it is under GPL, and as such he is in breach of the licensing for him to only release a ‘compiled’ version
2. there are comments that the miner is taking WAY more than 2%

Steer clear of this coin stealing scumbag

2.3 Mh/s from each Powercolor 280x (1.1 v), my config.

Like above posts say, he has breached GPL and the original dev has given him 30 days to correct this, before legal action.
Remove 2%, start miner, then press P C 0 (0 (zero) does not show in list but this still works, the dev has stopped you seeing it, so you think you cannot change from his pool)

EDIT TO ABOVE…………………….

3.3 Mh/s not 2.3 Mh/s…….arghhhhh !

P C 0, then, and forgive my ignorance, what comes next?

@Owen. then enter keep pressing space until you see your familiar screen

This runs fine on my desktop with an old GPU, but on my mining rig with 4 AMD R9 290X’s I keep blue-screening as soon as this modified SGminer tries to fire up. SGminer 4.1.0 runs X11 fine on the same system. Any ideas what’s going wrong?

Anyone tried these on r9 290? I see no performance gain

From what I gather this is not optimised for 290’s, however there is the other one that has the 2% removed that is working for 290’s.

Have the updated kernel. I’m so Used to scrypt hashrates that my 5870 gives me quite the bit of excitement… 1.6MH/s
