NSGminer v0.9.2: The Fastest Feathercoin / NeoScrypt GPU Miner

FlatBlack

*update

NSGminer performance using amd-driver
Crimson Edition-Hotfix 16.2.1, Running around +/- 6 hours
As picture below attached
alt text

*as im still at ‘beginner-level’, had experiencing so far ‘no-blackout @ other problem’ using custom-installation option, with just only AMD Display Driver or with combination with Audio Driver/CCC or all of 3 on Windows 7 64 bit

asking an opinion from ‘experienced’ n ‘earlier gpu-miner’, so far as conclusion…NSGminer 0.9.2 (Windows platform) is compatible with d latest AMD Driver…?

@FlatBlack what does your miner config look like for that ? and do you know how much power you’re drawing ?

*@aciddude soori fren for late reply… too sleepy… :3( just awake

NSGminer config

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100

nsgminer --neoscrypt -g 1 -w 128 -I 16 --temp-target 75,65,75,75 --temp-overheat 90 --temp-cutoff 95 --gpu-fan 85,60-75,80-85,80-85 --gpu-engine 1100,1120,1000,1110 --gpu-memclock 1300,1500,1300,1300 --queue 0 --scan-time 10 --expiry 60

*-using 3x r9 290 (reference), 1x r9 290 (yellow with 3 fan), finding that i need to re-arrange d position follow with usb-pcie slot number, is it…? which is for display,which is with 3-fan…

abour power usage
-using 1x thermaltake 1500watt
-dun hav any gadget or dun know how to calculate
-dun know which bios need to flash for ‘low voltage high performance’
-so far just referring d bill by end of d month only, then change d setting of electric-digital-meter for house…phisically…for getting d profit-target (this is like ‘guerilla’ way of electric saving…its wrong-action to do…as for advice… :3) )

about temperature
-its high due to ‘el-nino’ season, ‘high-dry’ not a ‘summer’
-fan so dusty, long-time not doing d gpu-servicing
-for people being inside ‘cool’-geographic atmosphere-environment, maybe it shows lower n better result ;3)

about d output-display
-im just doing d select at NSGminer-internel selection
-if not mistaken, when NSGminer had run, i hit d ‘D’, and hit ‘D’ again for ‘debugging mode’
-like to see d ‘Yay!!!’ word thing… ;3)
-try to explore some other different ‘notification-statement’ in NSGminer compare to SGminer ;3)
-finding if NSGminer display ‘Find BLOCK!!!’, we are really get a BLOCK!!!
.
.
**due to setting/setup, if finding some of my current parameter/config is useless/don hav an effect with d NSGminer result/performance, do advice me plezzz…
i needing that…‘learning process is never stop’…

@FlatBlack Nice One dude.

I’m going to try this on one of my rigs. I’ve got 4x R9 280x OC’d

There are BIOS flashes you can do…I did this for my MSI cards which lowered the voltage, but this was in the days of Scrypt Mining, with NeoScrypt I’m not sure. Ghostlander would know more.

oraleeee, fren… if not mistaken, for sure u can get d better results.
its r9 280x OC…nice…!!!

‘afraid’ to refer to @ghostlander…currently… :3)
hope d FTC-blockchain-protocol issued is doing ok n stable now…

if u dun mind
-which method is better for good-end-result of mining-activity…with solo, with pool @ with p2p node…?
-how many rig u have currently…? hows d ‘profit’ number, roughly…?

NeoScrypt CPUminer v2.4.3 is available. Upgrade advised.

https://bitcointalk.org/index.php?topic=712650.msg14253411#msg14253411

ghostlander

My NeoScrypt CCminer fork: https://github.com/ghostlander/ccminer-neoscrypt

NVIDIA Maxwell only, CUDA 6.5 or newer. Works with Windows XP or newer and Linux of course.

wrapper

I’ve finally switched over to NSGminer, R9 270, Linux 14.04 Catalyst 14.3

git clone https://github.com/ghostlander/nsgminer.git
cd nsgminer
./autogen.sh
make
sudo make install

I’m using this switch

–neoscrypt -g 1 -w 128 -I 13

I’d be interested if any one knows a better setting, however hash rate has gone up from 73 KHash/s to 183 KHash/s.

I tried some adjustments, so far…

-g2 - and that drops the Hash to 153 kHash/s

Thanks again for all your work, apart from being pleasing, the extra hash rate increases the security of FTC and other neoscrypt blockchains …

wrapper

I’ve got my R9 290 up and running mining Neoscrypt .

Kubuntu 15.10, fglrx 15.20.3,

./nsgminer --thread-concurrency 22516 -g 1 --lookup-gap 2 -w 256 -I 13

~485 kHash/s

./nsgminer --thread-concurrency 40200 -g 1 --lookup-gap 2 -w 256 -I 13

~495 kHash/s

Note : if I included set commands, crashed the system, so didn’t use those with NSGminer.

set GPU_MAX_ALLOC_PERCENT=100
set GPU_USE_SYNC_OBJECTS=1
timeout 1

Note : Maximum Intensity with NSGminer is 13

@wrapper NSGminer ignores thread concurrency and lookup gap.

Hello guys,

I am trying to build nsgminer [ghostlander] with mingw32 on win 8 32bit and I have one problem which bother’s me

“configure: error: Could not find pthread library - please install libpthread”

I have installed this library and I have no idea what to do , i checked everything in google. If somebody has some idea, I would greatly appreciate it.

Thanks!

ghostlander

@jumparo Well, it certainly needs a threading library. It’s bundled with MinGW usually. You should be able to locate libpthread.a in c:\mingw\lib or something like. What version of the compiler do you use?

jumparo

@ghostlander I have this file in c:\mingw\lib. The compiler is “gcc version 3.4.4”. Have you tried to compile nsgminer with mingw32 or how have you compiled it on Windows?

ghostlander

@jumparo GCC v3.4.4 is very old. I build with v4.6.x, though anything newer should work as well.

jumparo

@ghostlander what OS did you use to build the windows binaries?
I tried to build it on Windows with mingw and msys2 but both failed in ‘make’ step because libdl is required and as far as i know this library is not ported in windows.

I’m now trying to build it on linux with mingw32. Can you tell me what did you pass to the configure script?
And do you use mingw32 ot mingw32-w64 toolchains?

ghostlander

@jumparo Windows XP 64-bit or 7 64-bit, doesn’t matter. Use configure from a Linux build. You only need to pass flags for Curl and Ncurses if configure fails on them.

jumparo

@ghostlander I successfully build it, but now I’m having “The application was unable to start correctly (0xc0000007b)” . Did you have the same error, and do you have solution for it ?

p.s I’ve tried already the most common solutions in Google and nothing helped.

ghostlander

@jumparo Either recompile with no NVIDIA support or start with --no-nvml or remove your nvml.dll library. It’s outdated probably and crashes the miner.

wec

Should I be running X in order to see the fan speed and temperature of my GPUs? I am running Ubuntu server LTS 14.04.X, AMD driver Crimson 15.12 for 14.04.X , and AMD app SDK 2.9.1. When I run in nsgminer -n. I get ADL initialisation error! Error – 21! Unable to load the Nvidia management library .
