16.1.0 release also working ustable.
i think its related to their fee servers.
miner doesnt come back to our mining server after mining for the fee.
Please check.

Grin32

Hi all,

Been racking my brain for weeks trying to figure out why my 2080 ti's crash mining grin31...I have a couple machines with 1080ti's and they run wonderfully, but this machine has 3 cards, 1 x 1080ti and 2 x 2080ti's and within a min or so of firing up the miner one of the 2018ti's crash - fans go to full bore and 0's show in afterburner.   The machine is quite powerful with an 8 core cpu and 64 GB of RAM.  I've got VRAM set to 80GB, my machines with 6 x 1080ti's runs great with 70GB...Power supply is probably on the edge at 850 watts, but I monitor the usage and run the cards at 65%..And the wattage stays below 700 ish on the machine...I've uninstalled drivers, swapped cables, tried different drivers, lowered the clocks...Any tips on what else I could try would be greatly appreciated.  It will mine x16r for weeks without an issue...It's not just this miner, it's all miners for grin31, but I posted here because this miner is the best which means this thread probably has some real smart folks...

1080ti, I use +115 clock + 475 mem for grin31 (I vary power 75 to 85%)

Where do you get the beta?  Is it a closed beta.

Miner just seems to stop mining at certain points, nothing is happening, no crash, just stops mining like it's in pause mode. Checking MSI Afterburner, all clocks are dropped down like it's not mining anything and miner screen is just sitting on idle. Is this a known issue? I have 8x 1080 ti rig using this new 1.09a version. It's been paused like this for 10 minutes now, I will be restarting it in a minute.

Update: I was about to restart it but I just decided to hit backspace to see if something happened and soon as I did it kick started again? Then I got this:

[ERROR  ] 18/05/09 22:52:56 submit_upstream_work stratum_send_line failed
[ERROR  ] 18/05/09 22:52:56 ...retry after 30 seconds

And then after a few more retries it kicked in and is working again.

Few more pauses have occurred, some for 2mins, some for shorter, but I don't know if it's because Suprnova is overloaded with 11k miners or what the deal is. Switching back to 1.08 overnight and switching to 1.09 in the morning when I can monitor it again.
