NSGminer v0.9.2:

Linux - GitHub (source code) https://github.com/ghostlander/nsgminer

32-bit Windows release : https://github.com/ghostlander/nsgminer/releases/download/nsgminer-v0.9.2/nsgminer-win32-0.9.2.zip

64-bit Windows release : https://github.com/ghostlander/nsgminer/releases/download/nsgminer-v0.9.2/nsgminer-win64-0.9.2.zip

NSGminer is an advanced NeoScrypt CPU and GPU miner with the OpenCL support delivering the best hash rates for the AMD Radeon hardware (HD4000 series and newer). Should be compatible with the latest AMD Catalyst drivers. Also provides limited support for all NVIDIA OpenCL capable GeForce, Quadro and Tesla hardware. No external dependencies other than libcurl. Getwork, GetBlockTemplate and Stratum protocols are supported.

Example configuration for R9 280X (HD7970):

Code:

nsgminer --neoscrypt -g 1 -w 128 -I 16 --gpu-engine 1000 --gpu-memclock 1500 -o stratum+tcp://some_pool:some_port -O some_user:some_password

–thread-concurrency, --shaders, --vectors are not used for NeoScrypt. --intensity or -I is the primary performance optimiser. May be set between 8 and 20 according to your video card’s memory size. For example, -I 16 means (2 ^ 16) GPU threads each of 32768 bytes = 2,147,483,648 bytes or 2Gb. There are some configuration tweaks available in neoscrypt.cl which might deliver a little bit of additional performance.

Yes, it’s cool that Ghostalander is maintaining a GPU miner for Neoscrypt.
The speed up must be in the miner code, I tried compiling in the Neoscrypt.cl kernel from it into sgminer and it still gives 75 KHash/s on the R9 270 under Linux.

ghostlander

I recall SGminer recommends to use xintensity. It isn’t guaranteed to deliver power of 2 thread numbers which is a must for my kernel. The classic intensity results in (2 ^ intensity) thread numbers which is fine.

AmDD

Are there windows binaries available?

ghostlander

@AmDD No, I don’t use Windows. Although I can compile the miner in a VM like anything else, I cannot test the OpenCL part if it works actually. That’s why no binaries at this moment.

Thanks for that Ghostlander, I moved over mining to Linux, but it’s great Windows binaries are available to those that need them from a trusted source …

AmDD

I normally bounce back and forth between Linux and Windows for mining. Its nice to have the option and I know a number of other users are Windows only.
Thanks for the work, @ghostlander !

@ghostlander its crashing on nvidia latest driver, if i load up visual studio to debug, the error is a memory access violation.

Screenshot here: http://puu.sh/mmQgw/2d732605b6.png

It creates the compiled binary, but nothing appears on the screen and it just crashes

SpartanC001

@SpartanC001 woops
just realised it did give an output: http://puu.sh/mmQjl/fce2a93dbc.png

It used to be for AMD drivers? Can you try the Nvidea miner, Wellenreiter says there is one somewhere on the forum … I’ll look later if you can’t find it / waiting to see what Ghost (dev) says…

Wellenreiter

I used the sources from here

There is also a branch for windows

I’m not aware of any pre-compiled binaries.

ghostlander

@SpartanC001 Assume it doesn’t work on NVIDIA. No NVML support compiled in, no compatible OpenCL kernel, no NVIDIA hardware to test anything on my side.

nsgminer-win64-0.9.0.zip can not download. where download it ?

lizhi

OK, Download it right.

SpartanC001

Ah, previous sgminers worked on nvidia, i get 765 kh/s on my titan x atm, so no worries about that, just wondered how nsgminer compared

finding this with nsgminer 0.9.0

‘Pool 0 is hiding block content from us’

ghostlander

@FlatBlack “Pool 0 is hiding block contents from us” means an overloaded Stratum pool most likely.

BTW, good hash rates. Four R9 290?

:grin: :relaxed: :blush: aaahhhh… thanx for clearing that for me, Mr @ghostlander

ur reply at bitcointalk last time, help a lots…!!!

below shows around 16 hours running with 3 x R9 290 (ref), 1 x R9 290 Tri X… is d temp. is at normal rate…?
