Hi ssong,
When you run multiple instances one of them crashes? Is this what happens? Can you tell us what is the error in the console, or post a screenshot?
So far, we failed to succeed when trying to reproduce this behavior. We suppose this is not common. We will keep testing this.
We have been working on a new version and introducing some more optimizations.
Let us know if you have any suggestion. Thank you for the feedback! 
Cheers
I am currently running miniz end process -> restart every 24h automatically.
I will pause and post an error message.
Thank you very much!
However, the error code on the processor seemed a difficult message to handle if I did not have a symbol file.

Sol/s:
Use Cuda 10.0 versions with the RTX GPUs. For the other GPUs you should test and see which performs best.

Happy BTG mining!
At these hash rates, miners are very close to break-even, even in US States with relatively high cost of power - despite the bear market.
Thanks for continuing to push the performance and keeping us mining!
Thanks for the encouragement.
We’ll do our best to keep BTG mining profitable

All issues have been resolved.
There was a new error in the 1.1k version,
It seems to be fundamentally based on my nvidia driver version.
windows 7, 1080ti, cuda8 1.1k
Give the 382.53 Nvidia driver.
I updated it to 419.17 and I have no problem for a few days.
Considering that there was no problem with the past EWBF or other minors I used, it seems to be a very unique peculiarity.
Your home page says win / cuda 8 376.51 or higher,
but, I think 39x or 4xx or more is required.
Thank you!
Hi ssong
thank you for the update.
Good that the new driver version solved the issue.
Since you now have nvidia driver 419.17 installed, you could try miniZ cuda 10. It might improve the performance.
What we recommend is based on NVIDIA CUDA Toolkit and Compatible Driver Versions information that you can find here (see Table 1., indicates the minimum driver version that is required). However, each person should try and check which is the best driver version for their own set up, just as you did!
Cheers

Very nice!
Can you also post a version showing a BTG example? We’d love to promote it. (Very little additional effort for you.)
Hi MentalNomad,
hope this is OK!

At 1080ti there was a nearly 5% performance improvement!!
In previous versions, the stack overflow error was reduced, but it was still quite common, so I was running the “error detection - kill - restart” script code together.
Thank you for always updating this update!
Hi ssong,
It is great to know you had a nice performance improvement.
It is hard to understand what can be causing the crash. Sorry about this.
Can you post here the miniZ log output right before this happens? You can just copy this information from the logfile and paste it here.
Thanks!
Cheers
oh, I just attached --log parameter.
I will paste it here. Thank you.
who implied nvidia 2080 gpu can’t be used for mining?
there was talk about some “hardware-lock” i highly doubted :))
