Hey all.  I took a bit of a different approach to the hash drops and wrote a script to check and restart Cast_XMR as needed.

Basically you set it up as a scheduled task and it will look at the current hash from Cast_XMR.  If the hash rates are lower than what you set, it will kill the miner and restart it.

I posted it on GitHub if anyone wants to have a look or try it out.  It's written in VBS so it's pretty straight forward to step your way through the code and see what it's doing.

Let me know if you have any comments or suggestions, I'm willing to spend some time tweaking this if anyone finds it useful.

Best to PM me directly or comment on GitHub.

i'm having some good luck now with longer campaigns with un-modded 56 bios.

had 48 hours+ with afterburner at:

1464 core
925 mem
+30 power (linked to temperature)
fan on auto

problem is, I have one gpu very sensitive to too much temperature and i'll lose hashrate so, i had to downtweak that one a bit.

I fooled with another one:

1464 core
950 mem
+30% power
55 maximum temperature unlinked to power
65% fans

this was pretty awesome, I was doing 1970 per gpu. However, again that one gpu sensitive to temperature lost hashrate after about 1 hour. I suppose if you got lucky and didn't have any offending gpu this would be good. or just downtweak the one that is sensitive. fans were loud tho.


Now, I'm going to start another campaign with settings that should feasibly be very stable:

1269 core
925 mem
0% power
50% fans
55 max temperature unlinked to power

1800 h/s for all 3 cards and very stable at about 155-160 watts per gpu at the wall. I like this one. The fans are on the quieter side and core throttling is nil. that was about as low as i could go on the power with this one or else the core would throttle.

Just wanted to say thanks to the cast-xmr team, great job on the miner!
I just started mining with Sapphire PULSE RX 570 - 4 GB, Modded bios, GPU 1350 Mem 1950 running under 100W, i get ~890h/s on Monero with cast-xmr miner.
The best i could do with sgminer and xmr-stak was around 800-820 h/s

1045CPU or 1405CPU ?

some parameter to lower the power to a gpu? I have 4 rx 480 and G 1,2,3 work fine but G 0 hangs less than a minute

thanks for your suggestion but I'm looking for something in the miner to lower power as in claymore the -h and -dmem is used.

yea soz im confused from test settings, took a pic of them including cast waterfall prints here:

I ran into the same issue with using 5 rx 580s. The fourth GPU always hangs. Try the previous version of cast and report back (version 7).

This is a typical riser issue.  Flakey risers can cause some very odd issues.
