Tried to run it on HiveOS, both on a single card, and a bunch of them - no way, the miner works for some time, with extremely low hashrate on some cards, and with zero hash on others, then system freezes. The 'lolminer' works however (more or less stably), so its not rig issue... I just read somewhere SRBMiner should be better for those older cards, especially given the fact they are in supported device list...
Have you tried to manually tune the --gpu-intensity parameter? Or anything else beside just starting the miner with the default settings?
Yep, sure, I did. Tried to run it with "--gpu-intensity 0", "--gpu-intensity 10", "--gpu-intensity 5", "--gpu-auto-tune 0", "--gpu-auto-tune 1"... No luck. First of all, it doesn't seem to pick up the intensity value I give it, while also doesn't completely ignore the parameter: if I don't set --gpu-intensity, the log shows intensity value of 32 takes effect; while when I set "--gpu-intensity 0", instead of 0 some other (higher than zero) parameter is used; when I set it to 5, I can see it is actually set as 17. Weird.
As to "--gpu-auto-tune", it looks like when normal tuning procedure is started, it never ends - it works for some minutes, until GPU freezes.
Though I did make some experiments, but didn't do too much of them (probably up to 10-15 attempts with different parameter combinations), because the rigs are remote, almost every such experiment brings it to hangup state, while my remote hardware reset procedure is somewhat complicated, so I just did experiments until my patience was exhausted... Then I came here to ask
