Can you tell me is it always the same care failing?
Usually there are different reasons that could cause this, the most common three are
- Too high gpu clk
- Too low voltage
- Algorithm error (writing to non allocated memory address)
I can not say which of the three is causing the issue here, but maybe you can share your settings for the 570 cards. Also note the C32 8G solve is rather experimental at the moment. It will get an update for 16G cards with 0.9.6 (and a slight speed improvement with 0.9.5, but thats only a bit + bit lower power use).
But I will recheck memory limits / bounds again :)

Thank you for the speedy response!
No, it isn't the same card failing, but I have noticed that its always an RX570 16GB card that gets stuck, and not the Vega Frontier Edition.
The RX570 16GB cards are at stock settings, no modifications.
I tried using both 120v and 240v type outlets with the miner and still arrived to the same issue. I have a brand new EVGA SuperNOVA 1600 T2, 80+ TITANIUM 1600W. The setup is only drawing 900w-950w when using the lolminer.
I did do some power draw tests comparing lolminer to Sapphire's ePIC miner and noticed that when using the lolminer the power draw for C32 was 145w-155w per RX570 card where as ePIC was drawing 121w-125w per card.
The extra power demand made sense why the lolminer dishes out hashes for C32 between 0.15-0.20 GPS where as the ePIC is at 0.101-0.103 GPS. This is all just with stock settings for the RX570 16GB cards.
I've tested C31 and hit the same "Stuck" error. I will try a completely different algorithm
than Grin's, like Beam or Zel to see if its an issue with the lolminer and these cards for Grin.
If you have any other suggestions, possible troubleshooting techniques, or in need of more information/screenshots please let me know. I would definitely like to use the lolminer more full-time.
That is refreshing to hear that you've been working on the next updates, excited to test out your latest updated lolminer when it comes out! Thanks again for your time.

@Lolliedieb Tried the 0.9.5.1 update, so far still getting stuck device error... Also 0.9.5 & 0.9.5.1 on Linux Ubuntu is lagging when it comes to the miner displaying the information as it mines. Looking forward to the next update. Hopefully taking advantage of the 16GB and a few other adjustments that can lead to more stability in the next update so I can begin using this miner 24/7, Cheers!

@Lolliedieb Tried the 0.9.6 update, and I am unfortunately still getting stuck device error... Sigh... Taking advantage of the 16GB has created spectacular hashing but stability issues are the same and still a card gets stuck after 2-4 hours, hashing goes to 0.
Perhaps an intensity adjustment feature for both the CPU and GPUs would help. It might be due to a low-end CPU bottleneck (I read somewhere that Grin's algorithms tend to like mid to high-end CPU power to solve), if I could lower the intensity to lower the CPU usage while shifting more workloads towards the GPUs maybe the GPUs won't get stuck.
In the meantime, keep up the good work and cheers!

Just wanted you to know that I had a similar issue on my 16G 570.
Reason: The settings coded into its firmware are more like eth settings and voltage is coded too low for the memclock. There is a firmware update that I got for my 570 16G that makes it work.

Could you point to me what firmware it is?

@alanng22 I want to know that too.
@Lolliedieb Got a link to that firmware update?
