I have been mining since Sept. Currently have 4 rigs and this 5th one that I'm trying to get stable. Current farm consist of 36 GPUs 24x 1060 6GB split between 3 rigs running about 550Mh/s on ETH, 8x RX 550 doing about 3.4kh/s on ETN and trying to make this 4x RX Vega 56 Rig stable, so i can have a total of around 10-11kh/s on ETN. The 1060s are super stable. 1 of the rigs has a TDR problem, but that is solved by a reboot by windows and then everything comes back up and starts mining like nothing ever happen. sometime Nanopool doesn't even register the drop on there site since it happens so fast.
I'm currently trying to get 4x MSI Vega 56 Air boost stable. Purchased EK watercooling equipment, but I'm thinking about sending it back if i can get this stable. I can't seem to get it working more then 4-8hrs at a time now. It ran for about 3-4 weeks with only one reboot in between and after that it was never stable again. I couldn't care less if the thing rebooted every 4-8hr as long as there was a way to automate the restart disable the cards, re-enable the cards start Afterburner and then start XMR-Stak. My other rigs which mine ETH just restart once in a while with a TDR error (did DDU and reinstalled drivers but still not fix dont really care about this since the restart takes care of it), but at least this rig just start up the miner starts afterburner starts and it back to business like nothing ever happen it takes a total of 1-2 mins tops. I don't even notice when it happens. I tried that Guardian software (from vega.miningguides.com), but it almost felt like the developer made it to reboot every 10 mins, so he gets his 5min of mining. i put most of the values at a ridicules rate like 2000hs and for it to wait 7 mins if the miner doesn't hash before it restart and it just kept restarting every 7 mins. I also have a RX550 x 8 using XMR-Stak and that runs for days before XMR-stak either stops responding or the whole computer just freeze and does nothing, but with that Guardian software it just kept restarting every 10-12 mins, so i stopped using it and it back to normal. I have tried using that Dev software, but it a hit or miss. Cast-XMR does the same thing, just reboots. Temps say at around 41-47c (fans are cranked up to 4k). so i know it not temp problems. Any idea what it can be. I have tried switching risers, power supplies since i have 4 other rigs and trying other drivers you lose about 2.5k hs. This is really frustrating. I mean has anyone figure out how to automate this. I cant care about monitoring. Just a way to cut power to the rig let it restart have it disable enable the cards start the OC program then start XMR-Stak or Cast or Claymore. Reason why i want to stay with XMR-Stak is because CPU miner never seems to work together with Cast-XMR together or at least it has never worked for me or i don't know how to set it up. Is there anyway you guys have figure out how to make the computer reboot and just automate the disabling enabling the cards this is the parts i don't know how to make happen. everything else is easy for me. If i was to have this ability i would just reboot the Rig every 4hr. i wouldn't mind losing 5 mins every 4hr. better then it randomly rebooting and nothing happening till you realize it or are sleeping and the machine just took a dump and you restart everything up ran for 10 mins you went to sleep and 10 mins after everything took other dump and wake up to realize you just lost like 6-8hr of mining because something went down. There is no logs or anything for you to look into either.
Here is my XMR-Stak Set up
2 thread per card (
at 1932 intensity (i have tried going as low as 1600 on both threads per card with the same results), Also which there as a real explanation for this intensity thing.
I also Mining with my CPU all the even numbers cores and every tried to assign the odd numbers cores to each video card with the same results. but for the most part i have it set up for core 1 to handle the GPU's which is the default value.
I use afterburner since very time i use overdrive the cards won't say running longer then 20-30 mins. AB settings
-10 Powerlimit
85 tempature
1407 Core clock
900 memory (tried 825, 850, 860, 875, 900) Left it at 900 because it almost feels like it doesn't matter)
75 Fan
Total watts at the wall is 920w

I have used this guide
http://vega.miningguides.com and i know most of you on here us a 64 and not a 56, but I'm very well aware that i can't run the card at this crazy number. I even tried the setting someone mention on here a couple post back. One thing at least with my other rigs that no one seems to mention is the Memory manufacture. does it make a difference for this HBM2 chips. just in case it does my cards all have Hynex and they are not modded. I tried some power play settings for power savings, but same things.
