RE: Ethereum AMD GPU Mining Tutorial Ubuntu 16.04 LTS
Unfortunately, I ran this miner and it creates a lot more heat than my Windows miner. I shut it down when my cards were hitting 85° C - I was researching a method to undervolt the core clocks and overclock the memory. The only ways I found were rather cumbersome. So if you figure out a way to tweak the GPU settings in Ubuntu, let me know. Granted, I was running this miner on an inferior test circuit and I did not have a fan directed at it... but the difference was noticeable just placing your hand behind the GPUs. It kept my tech room warm this morning that's for sure!
I have not had that issue at all. I have rx 580's with the hardware bios switches on the physical gpu and im running the btc gold motherboard so that offers me the ability to OC everything from the bios on the motherboard. I knew that the GUI software for OC functions weren't going to work on Linux. (they work well on windows though)I even tried to use wine to open the overclock GUI software that comes with the AMD GPU's but that didnt work. Hence the motherboard Overclock feature. I actually threw my first one out because of this issue... I am going to have to switch over to mining on windows though... Im prepping for the swap using my test rig now... Bye Bye linux! you were there for me back in the day but.... hahahaa
That's for that tip, I'll have to try that! However, with all the old Windows 7 pro licenses I have sitting around, I'm probably going to go that route with this rig too, but I'm not done with Linux yet - this machine just needs to be up and running as soon as possible!
UPDATE
Windows 7 is a no-go on the ASUS B250 motherboard. The only image I have, however, is the 48-in-1, Windows 7 with many versions (it's always worked well for everything else in the past). So Windows 10 it is... and I was able to get a W10 pro key for just 5 Euro ($6.38 in the US). It activated no problem and was instantly emailed to me... gotta love eBay. So we'll stick with Windows due to its versatility to easily switch algorithms as Ethereum mining is becoming less profitable by the day!
Made a video based on this write up if anyone wants to check it out:
This is a fantastic video man! You did well! great setup! all the undervolting haters can kick rocks! theyre just jealous!
Thanks man! Linux builds are fun - much more involved. It seemed to get better hash rates as compared to Windows running Awesome Miner. Think they might be skimming a little too much off the top as our pool never shows the rates that they miners are reporting. Not sure what's up with that, should only be 1-3% at most.
I dont mind skimming if the percentage is low... I like the dev's to make their money but gauging is a whole other thing. I haven't had a chance to test windows on the test miner. I'm moving back to seattle at the end of the month from texas... so i have my hands pretty full at the moment but as soon as i get settled in im gonna get the workshop up and going!
Look forward to seeing it, man! Honestly, the build in the video I made was for a buddy of mine. I have another 13 GPU mining motherboard but need to wait until more funds are available for another miner.
I'm running my rig on Ubuntu server with 5 Sapphire Nitro+ RX580's, trying to locate longer PCIE power cables but not easy to find in my area. As I do have one more RX580 not mining at the moment. Anyways back to my thought. So does this mean it is better to mine with Windows over Ubuntu? I am also getting roughly 19.38 Mh/s per card. Does flashing the GPU bios help with the hashrate in Ubuntu? Or is this mainly a Windows thing to do only? I could flash each card in my Windows machine but will those setting then work when I move it back to the Ubuntu rig? I'm using the AsRock H110 Pro BTC+ board. I also read somewhere where don't remember where but will look for it again that I can undervolt with a command in Claymore. Can you confirm this?
I have found more info and it appears that I cannot use Claymore in Ubuntu to undervolt or control the GPU too much. All I can do is flash the bios and get a better hashrate. But if I was to switch over to Windows well then that is another story. I'd be able to use software to oc more and control more. I'm not sure if I want to change over since it is working now and I am not sure if using Windows will really give me a much better hashrate than I am getting now. Currently getting around 29.XX per GPU, but read can get about 30-33 in Windows. Is the extra hashrate going to make a big difference in mining?
That depends on how man cards your running. if your running six cards its an extra 18 mhs. which is pretty good! but this is why i mine with RX 580's... the have a bios switch on the card specifically for mining. that eliminates the need for all the undervolting and overclocking messes... longevity is the name of the game here and ive found that these types of things dont do well for the cards... it can fry them over time... super stoked you found all the tutorials helpful. Post back and let us know how your rig is doing
I am running 6 GPUs with the bios switch as well. And so far things are running pretty good! I have only had one blip but not sure what was the cause. Had to do a restart and that was about it. Since then it has been running pretty good. At the moment it is still cool in my area but once it starts to warm up I have to think of how to deal with the heat! I do have a few fans mounted on the rig to get some better air flow but I am not sure if that will be sufficient! I guess I will deal with it when the weather gets warmer!
I got my first rig going in texas and the heat didnt bother em too much. I wouldn't over think it. Now taht im in washington it is going to keep my office warm in the winter hahahaha
I recently rebuilt my rig and now everything mines at 0.00MH/s. Everything has been installed and configured the way it was before. I tried moving the video cards onto difference PCIe slots and difference cables etc. but nothing seems to work. Sometimes I get one or two GPU's to work but the rest are always at 0.000 Mh/s any ideas what is causing this?
