Bminer 15.7.6 Fix Cuckaroo29d on RTX-series cards

It´s the same issue that occurs to me.
I´ve the latest driver but after few hours or days the miner just dies and restart is necessary to work properly again.

Interesting that this issue occurs only on PC with single 1070 card, on my rigs with 5-6 GPUs everything is well.

Isn´t it just problem with 1070 - 1080 gpus?
I am mining with one 1080 ti & one 2080 ti and I think these cards together make it not comfortable for miner. Are your stable rigs composed of pure 2080 Ti or also 1080 Ti?

may I ask what’s the OS?

may I ask what’s your OS please? thanks! we will fix it ASAP.

Win 10 Pro 64bit.
Thanks for your support! :sunglasses:
Btw, I think it´s the same issue on both Linux & Win OS.
I made the whole topic about this issue, if you want to go through it, check this link please :

Are u laughing ? :wink:

Linux aw1 4.13.16-hiveos #1 SMP Tue Apr 17 18:30:28 EEST 2018 x86_64 x86_64 x86_64 GNU/Linux

Mining C31 with my 2080 RTX TI on Linux with Bminer used the 11GB algorithm, but on Windows 10 x64 Bminer sees only 9GB free and falls back the 8GB algorithm.

I checked using nvidia-smi that there’s no process running on the GPU and it reports almost full 11GB free. My display is connected to the integrated VGA so the GPU should be totally available for mining.

Is it a known issue? Are there any workarounds? I use Bminer 15.4 and the newest nvidia drivers.

I can´t even run C31 on Win10 with my RTX2080 Ti.
It runs only solo, but when it´s together with GTX1080Ti, it is forced to work lower on C29 8GB algo.
On Ubuntu, it can´t run too on C31. Only when solo.

We’re pleased to release Bminer 15.5.0.

The release provides:

  • Improve the performance of the Cuckatoo algorithm.
  • Support dual-mining ETH and VBK.
  • Add the parameter -version to output the version and exit.

Sample Usage of dual mining ETH/ VBK

bminer -uri ethash://0xb76d43eAaB2e905028a7f0F3aF13C7A84c477B9f.worker@eth-us-west1.nanopool.org:9999 -uri2 vbk://VAR5uzCpFNfmTDZQQmfHUgbpY7NS93.worker:pwd@vbk.f2pool.com:3500 -dual-intensity 10

-dual-intensity is for adjust the performance manually, so you can adjust the intensity by adding it at the end.
-dual-intensity 0 means mining eth only.
-dual-intensity 3~10 is recommended.

Happy mining.

Thanks for the update, however, the unknown error still lasts …
CUDA error DRIVER: ‘1’ in func ‘bminer::cuckoo::Cuckoo29SolverCudaBase::InitializeCudaEnvironment’ line 212

Thanks a lot. My four 2080Tis under Ubuntu 18.10:

Pretty high temps, aren´t they?
I am not crossing 60°C. Why don´t you run fans 100%?

I don’t know how to set it to 100% speed under Linux. :confused: So it seems that the driver is setting the speed, so I think nVidia engineers know their work well and te GPU is OK in this mode.
I will try Win10 on this rig when I’ll have some free time… just for this purpose.

Now I understand. I was thinking exactly about this thing when I was testing mining on Ubuntu (how to control speed of fans), but never come to that point and switched to Win.
To achieve less than 60°C on my RTX it has to run 100% speed, but the GTX is running just on 65%. But it´s probably about the build of the card and the brand. Anyway, I also added some extra F8 Arctic fans under the cards, so it´s pretty well cooled with these external fans.

I’m getting an 8% improvement on Grin 31 over the 15.4! And the power usage and temps are a little better. NVIDIA Grin 31 : Thanks!

EDIT: 3% at the pool side, but still, very good!

Any idea how to find out which driver is used on Win 10?
I definitely have the latest Cuda toolkit installed, but not sure how to find, if the driver is 410.66.
Also, not sure how to reinstall the specific driver if needed and not touch the latest toolkit.
Thanks.

To check the driver, right click the desktop and go to NVIDIA panel…
To Uninstall just the Driver, go to Control Panel and Uninstall a Program, and select only the Display Adapter Driver…

PS - not a good Idea to uninstall and reinstall a different driver then what cammes with the toolkit, but it might work…
