[ANN] sgminer v5 - optimized X11/X13/NeoScrypt/Lyra2RE/etc. kernel-switch miner

[Lucif3r]

Anyone here successfully run this on PIMP/BAMT? I've been trying in the past weeks without success. All I get are HW errors and 100% rejects (share above target).

Here is how I compile:

git clone https://github.com/sgminer-dev/sgminer.git
      
cp /opt/miners/sgminer-4.1.0-sph/ADL_SDK/* /opt/miners/sgminer/ADL_SDK/
   
cd sgminer
   
sh autogen.sh
   
./configure   
   
make

Here is my config for 280x and 7950. Both give those errors:

Changing "pool-algorithm" value to x11mod or x13mod doesn't help at all. Please someone tell me what am I doing wrong?

anyone?

try c
you are cloning the master branch
edit:
if this doesn't work try

Code:

cd /opt/
rm -frv sgminer
git clone git://github.com/sgminer-dev/sgminer.git
cd sgminer
git checkout v5_0
cp -av ../ADL-SDK/*.h ADL_SDK
autoreconf -fvi
./configure CFLAGS="-O2 -Wall -march=native" --enable-opencl
make

Thanks badman. git clone -b v5_0 git://github.com/sgminer-dev/sgminer.git does the trick. I wonder why this kind of information is not easy to find for newbie with github like me

[cgladue]

Yeah, it's Scrypt-N now, and we're still on X11

Thank you NiceHash Devs, i just noticed you did a quick software release and now the front page is displaying the most profitable algo correctly to what the stratum is showing...

Yes fixed now.

Switching successfully between Scrypt-N and X11 here with no hiccups.

even after setting all engine and memclock speeds tot he same using your example i still cannot switch from X11->scrypt-n  when i do it says 2 of my 4 cards threads hung and then the cards go DEAD and/or freeze the computer with a driver not responding error.

but if i manually start and mine scrypt-n or x11 as the only pool it runs no issues for days

Try replacing your conf with exactly the one I have.  If it works, recursively check to see the differences between mine and yours and report back.

im running 4 x 270x so i cant use your verbatim, but i did copy and paste and only change my BTC address and the memclock/engine clock, xintensity, TC

Change your shaders to 1280 also...

* You've got your Scrypt-N port on 3335, when it should be on 4335.  4335 is the multiswitch port.
* Instead of Intensity, do "xintensity" : "200".  That'll give you close to -I 18, but a nice even number based on your shaders.  See here for more info on xi
* Add "vectors" : "1"
* Add "scrypt" : true
* Change the kernel in your main conf to ckolivas

If that doesn't do it, the only other thing that sticks out to me is the "queue".  Try changing it to 1 or 0... I've never seen it at 2. (dunno what it does either)

I have changed form lazybear to this version for my 6-270x by sapphire rig.No significant boost seen.Still about 2.1m/s.Here is the conf.

Has anybody succeed with catalyst 14.6.I saw 2.6m/s but hw appears.

[bullus]

Finally it is stable for 24hours..I think I know why it is stable now.

I deleted
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

I deleted

setx GPU_USE_SYNC_OBJECTS 1

Coincidence, these commands are not needed in the batch and have no effect if present.

maybe, but did u test it by urself?.. I often got a sick or dead gpu, even upped the vgpu, sometimes just a hard reset after 12hours.
It works for me so yes maybe coincidence..

I don't have and never had setx commands in the batch.

As to why is it coincidence, setx sets environment variables, which 'stick'. So if you did it once and rebooted - no need to set them over and over again. Those particular settings MAX_ALLOC and SYNC are used by OCL runtime. It either finds them in the environment or not.

When you removed setx commands from the batch they are set anyway and OCL runtime still uses them. So nothing was changed when you removed them from the batch. But you say something changed - coincidence.

If you want you can read more about setx, tho it's a lengthy and confusing time to time ; )

No I completely deleted the environment variables out of Windows, and haven't run any new ones, still same results, am testing stability over a long-hour period.

For proof of course

Code:

[05:21:43] Started sgminer 4.2.1-120-gc0d7
[05:21:43] Loaded configuration file C:\sgminer_multi\sgminer-nicehash.conf
[05:21:44] WARNING: GPU_MAX_ALLOC_PERCENT is not specified!
[05:21:44] WARNING: GPU_USE_SYNC_OBJECTS is not specified!

So it appears the miner is in agreement that these environment variables are no longer set.

[lbr]

No I completely deleted the environment variables out of Windows

On my rigs if I do that miner won't run at all, cause I'm using high thread-concurrency for scrypt and scryptn.
And OCL won't be able to use GPU RAM to load kernel. scryptn uses ~2.8GB on 290 and scrypt ~2GB for me.
For x11 and x13 TC does not matter(at least on my rigs) so prly there is no need for MAX_ALLOC. And what SYNC_OBJECTS has aeffects on x11/x13..  no idea. For scrypt if it is not set I was getting 100% CPU usage on some rigs and on some it didn't have any effect.

* You've got your Scrypt-N port on 3335, when it should be on 4335.  4335 is the multiswitch port.
* Instead of Intensity, do "xintensity" : "200".  That'll give you close to -I 18, but a nice even number based on your shaders.  See here for more info on xi
* Add "vectors" : "1"
* Add "scrypt" : true
* Change the kernel in your main conf to ckolivas

If that doesn't do it, the only other thing that sticks out to me is the "queue".  Try changing it to 1 or 0... I've never seen it at 2. (dunno what it does either)

i will try your suggestions, i usually have it on 4335 but set it to 3335 just so i can force it to to be the first alive pool for testing, then i can switch to X11 and back since both pools are alive.

i will test once i am in front of the rig just in case it hard-hangs and i need to reboot

KiloWatts,

Everything worked fine switching from Scrypt-N to X11, but then when switching back from X11 to Scrypt-N GPU1 and GPU3 seemed to make the switch OK (i was even getting accepted shares from those 2 cards), however just like before GPU0 and GPU2's thread never got cancelled and re initialized, after a few mins they were declared SICK and the display driver stopped responding.  Also a message about the thread being hung displayed and needed to power off and on the entire rig.

Could you please run sgminer in debug mode with output to log file (sgminer ... -D 2>>sgminer.log), simulate the issue with witching from X11 to scrypt-N, and then describe your issue and attach the log to this issue https://github.com/sgminer-dev/sgminer/issues/264 ... this will help the developers.

all set i just commented and shared the debug log link with them .... i hope it helps get this taken care of, cant stand not being able to switch back and forth and have a stable miner.

[mannyg]

I switched to dedicated X11 mining and was still getting the occasional SICK GPUs.  I lowered the memclock 10mhz and it seems to have gone away for 3 days now.  Much of the issues with switching and sick GPUs can be solved by lowering the tuning of their gpu engine and memclock and perhaps even intensity

[ashleysly]

I will try this sgMiner. Didn't know a new one was released.

Ill report back to you with my problems, if any.

[KiloWatts]

Mine has been good for 48 hours now...  I do occasionally get a smattering of HW errors, and rejects (10%) with Scrypt and Scrypt-N though...  but no crashes.
