Optiminer/Zcash v1.7 (GPU, Windows+Linux, AMD)

[thilan29]

V1.5 and V1.6 have been crashing the 16.11 driver on my 290.  This happens at stock and overclocked.  Actually it's weird, I ran 1.5 from release right up until last Tuesday, so about 7 days, when it hung.  Since then I cannot get V1.5 or 1.6 to run stable at stock or overclocked settings.  This happens with stock or modded BIOSs.  V1.3.2 runs without any problem, but speed is lower.

Could something have changed server side on Nicehash that is causing the crashing?  Temps are fine as it is watercooled and VRMs are staying at under 70C.  Not sure what could suddenly cause the instability.

I have the exact same problem . On my rx 480 (modded or not modded) on Optiminer 1.5 or 1.6 . Temp of mobo,gpu,vrm,.. are fine too. It stop after less than an hour . I didn't test v 1.3.2 tho . So weird

Nice job on the r9 nano. The 7970 are crashing. Opencl decice not found.. the bin file is missing

what is the correct bat file
for watchdog enabled option?

because some card stop working after some hours?

[rayday11]

1.6.1
- [1.6.1] Print warning when running on non-optimal driver/platform.
- [1.6.1] Fix: Don't try to run on non-AMD GPUs.

same problem. also asking for help.

files
does anyone have working bat file

for watchdog enabled at windows 10???

I use Linux.

The watchdog-cmd.sh (that comes in the compressed file along with the binaries) is the shell script that has to be run when a card stops responding. You need to edit it and enable the method that works best for you. My watchdog-cmd.sh looks like this:

#!/bin/bash

## Hard reset: (Requires 'Magic SysRq key (CONFIG_MAGIC_SYSRQ)' enabled in kernel.)

echo "--------------" >> /opt/optiminer/optiminer-zcash.log
echo 1 > /proc/sys/kernel/sysrq
echo u > /proc/sysrq-trigger
sleep 1
echo b > /proc/sysrq-trigger

The mine.sh has the watchdog-cmd.sh already configured.

In my case, the watchdog-cmd.sh never gets fired, so I wrote another script to monitor the log file and wait for something like has not produced any solution in it, when the text is found, the script will call the watchdog-cmd.sh. This solution has been working for me quite fine.

I'm currently not using windows, but you could try creating a BAT file (watchdog.bat) with the following:

shutdown -r -f -c "GPU card freeze"

Then configure your start.bat to look something like:

optiminer -s %POOL% -u %USER% -p %PASSWORD% -m 8080 --watchdog-timeout 30 --watchdog-cmd "watchdog.bat"

I found these links for reference on shutting down a mswindows computer:

Let me know if this works.

Optiminer since 1.5.0 (1.6.0 and 1.6.1 too) is still not working with modded R9 390. Though Claymore 11.1 works like a charm

v1.6.1
2x R9 390 ~750 S/s
volt    +13 mV
cclock   1110
mem     1500
temp     69 C

Very good work dear sir! You are a gentleman and a scholar.

Can anyone help me improve upon this?
Also, is there any log option for optiminer?

Ty esteemed gentlemen.

Very unstable in 1.6 and 1.6.1  Crashes daily.  Some card don't even hash even after a hard reboot.  Have to switch back to Claymore.

I'm running Linux with the 15.12 drivers (R9 380 & 380x cards) and the Readme specifies that should be using "fgrlx 15.30.3".   Am I going to notice a difference if I spend the time to upgrade to the newer driver?   changing drivers can be such a pain that I hate to waste the time if I'm not going to really benefit from it.  I already took a big jump going from claymore's 11.1 and (knock on wood) 1.6.0 is running stable.

so is the driver upgrade worth it?

First, I have Nanos, so the optimized kernels are different than yours, but when v1.4 came out with the asm kernels, I couldn't get it to run, even though v1.3.2 ran fine. I was running fglrx 15-201 drivers. Optiminer told me I needed to update to the latest fglrx driver, which is 15-302. I did, without too much pain, and v1.4 ran fine. But, since you are up and running stable, I wouldn't bother, just keep it in the back of your mind if/when some future miner update fails.

I second that. If things are running fine with Linux/fgrlx 15.12 just keep using them. There should not be any speed difference in this case.

Sounds good.  Thanks!

Ty esteemed gentlemen.

Yes.  Why not volt -50 to -75 for example.  You will save power.  Risk is that it crashes. 

[jelin1984]

how I can fix that?


gpu3 waiting for work from the pool

and miner does not start
is not pool problem

[thesaltonsea]

yes its little faster than claymore , but its getting from 500 to 1500 on the pool ... thats not good, with claymore is 1300-1500sols ...

That's variance in the pool performance, not the mining software, but believe whatever you'd like.
