[Dev] NeoScrypt GPU Miner - Public Beta Test
-
Pair of Sapphire R9 270 none X at work, as a test only. Still unable to get solo mining to work.

I would think that that is probably about normal for neoscrypt?
From my CPU mining I’ve seen that neoscrypt has a pretty low hash rate when compared to other types of scrypt mining.
I did think it looked a bit low, but there was no tweaking or overclock done.
Its kinda strage… i am getting 8khs out of 550M… there is a huge difference between 550M and 560M
Next week I will be testing the 7990s the heavy artillery :D

I think there is an endian issue between the cgminer and the PXC wallet.
I think the same issue also occurs if you try to solo mine using minerd, which is why solo mining only works if you use the wallet itself to mine.
Sorry I can’t be more specific than that as when the Dev discussions starts getting into that detail it goes over my head.
I’m sure I saw a post that one way around this at the moment is to set up your own P2Pool, but don’t advertise it, so essentially you are solo mining via your own private P2Pool

I have compiled the 3.7.5 code from vehre but i get no accepted shares. Anybody an idea what im doing wrong ?
cgminer --neoscrypt --worksize 128 --thread-concurrency 200 -o stratum+tcp://pool20.neoscrypt.de:10554 -u PqQUhPTznbRWxGgZYyNRGyPxjj71oVL9Ax -p x
I have compiled with
autoreconf -fvi
CFLAGS=“-O2 -msse2” ./configure --enable-neoscrypt
make
strip cgminer
no errors
-
@daimyo I think the low khash may be because its set to I 8 auto I guess because I didn’t set anything for that setting like I did for the R9 270’s.
@ I 13 Edit: doing a quick test at -I 10 and seeing 12.70 kh/s -I 11 -I 13 makes the PC to sluggest almost unusable with a loss of kh/s
10 seems to be spot on for this 560M.
@tmuir12 The minerd works just fine in windows 7 and wasn’t much of a problem at all to get working.
My wallet is on one computer and I am mining with five other PC’s across the network to that wallet.
I also use minerd on this laptop and use localhost or 127.0.0.1 to connect to that wallet. In Linux there
was a problem getting minerd to find or see the wallet and I did have to use the wallet software in Linux
to mine on my Quad CPU 32 core server rig.
A simple command line like this works across the network to the wallet there.
minerd.exe --no-gbt -a neoscrypt -R 10 -o 192.168.1.107:3333 -O phoenixcoinpc:x --threads 6
This isn’t from my server wallet but I’m pretty sure these are the phoenixcoin.conf lines that are working for me.
I’ll update if its different from what I’ve posted.
server=1 daemon=1 defaultkey=1 logtimestamps=1 dns=1 addnode=prometheus.phoenixcoin.org:9555 addnode=menoetius.phoenixcoin.org:9555 addnode=atlas.phoenixcoin.org:9555 rpcuser=phoenixcoinpc rpcpassword=x rpcport=3333 rpcconnect=192.168.1.107 rpcallowip=192.168.*.* -
I agree with Bushstar, we need a well tested change over to neoscrypt and GPU mining is an essential element. Thanks for all the great work…
-
@ the solo miners: Please report if you have a 64bit or a 32bit Windows and if solo mining works for you.
For 64bit Windows some recent changes have been made, but are not tested (I am on Linux and only have an XP VM, with no graphics card attached).
We are still in the beta phase and a lot of intrinsics in cgminer are not yet understood completely. Feel free to look into the code to get an impression of what we are facing (calling it unstructured spaghetti is too much of a honor for that artifact :)
The first goal was to provide a working gpuminer, the next goal is to provide a fast GPU miner.
-
I’ve got 3.75 compiled and running under windows, but it won’t let me set gpu clock speed, or any of the setting below I normally use, it tells me they are unrecognised.
Did I do something wrong compiling it, or are they not working in this beta?
I previpus got around 26Khash, I can’t get better than 18khash with the one I just compiled
-auto-fan --auto-gpu --gpu-engine 1180 --gpu-memclock 1240 --temp-target 65
But as a plus no HW, just a few rejects
-
@tmuir12: for which Graphicscards vendor? Nvidia just can report temperature and fan speed for AMD you need to have the SDK available and follow the instructions in the ADL_SKD/readme.txt to have adl-support available. May be you also need to set the AMDAPPSDK environment variable previous to build. I won’t ship AMD’s file with the miner, because they belong to AMD and have there copyright in them.
-
I follow the windows build instructions and downloaded the AMD files and installed them as directed in ADL_SDK, didn’t set any amd environment variables prvious to the build, will look at that
-
Also make sure that AMD’s management .dll is available to the miner, e.g. in the same directory like the cgminer.exe. The name of that lib is atiadlxx.dll or atiadlxy.dll for 64-/32-bit versions of the library, respectively. Don’t remember which version is which, just make them both available, the miner will figure which one to use. For Nvidia the nvml.dll needs to be available.
-
Found my issue I let cgminer create the conf file then just changed a few settings, failed to notice it had set GPU threads to 2, changed this back to 1 and its now working at normal speed.
Will continue to tweak it
-
Note for Nvidia card users, I had a good bit of HW errors with 3.7.1 dropping the command line --thread-concurrency as any number used here
would still cause HW errors. Also found I got a little better kh/s out of my 560M by using 64 or 128 with --worksize, avoid 96 as it doesn’t work at all.
Not sure if all this is just something on my end or for everyone so its something you should test for yourself.
-
Is there also a linux version available for the GPU miner? I could run some tests on a 7950 card.
Not sure if it helps - i have also installed a PXC p2pool on p2pool.maeh.org:10554. This one uses the ghostlander source from github and is in a p2pool network with pool20 and p2pool.neoscrypt.de - so that looks fine right now.

Your p2p seems to be working for me I’m in testing now, but am unsure as to how this all works as this is my first p2p test ever.
No status showing up yet for my wallet address. Pn18tqfzFNPUcFjJRq1GRYdYDJjKTBNGpq Guess stats will show up in time?
Next step will probably be setting up and testing the making of my own p2p.
I’ve also tried these two
p2pool.neoscrypt.de:10554 located im Germany
pool20.neoscrypt.de:10554 located in the Netherlands
but got nothing but rejects from both.
-
Status on the main page of P2Pool can take up to 30 minutes or more to appear.
If you click on the link to classical interface you should be able to see something after a few minutes, but it still takes some time to show you full hash rate.
I also find that the pool shows my hash rate as about 70% of what my miner shows.

I must be doing something wrong with my command line setup because still not show up or any stats.
I used my wallet address as user name and password x and also add my wallet address to the Set my Miners.
Been hours and still nothing showing up. Below is my config. See anything wrong with it and maybe the cause?
I’m looking for stats at this address: http://p2pool.maeh.org:10554/static/#
Maybe not the correct place to look?
cgminer.exe --neoscrypt --worksize 128 -I 10 -o stratum+tcp://p2pool.maeh.org:10554 -u Pn18tqfzFNPUcFjJRq1GRYdYDJjKTBNGpq -p x
-
That looks correct to me, but I’m at work so cant compare it to mine to be sure until I get home
-
Something isn’t right after 25k+ accepted and still no sigh I have ever done anything I shut it down.
-
I think its a different pool I’ve been testing one, will try that one tonight.
-
For cgminer only p2pool.neoscrypt.de, pool20.neoscrypt.de and pool.ftc-c.com are adapted and working.
My version of p2pool and ghostlanders p2pool code base are 99% identical, but not the same.
If you get only rejects from the pool, you are probably not using the latest version of gpuminer, which is 3.7.5 at the time of writing. Older versions may work for longpoll, but don’t work for stratum
