Hi guys, I have a maybe stupid question. Suppose you are buying 10 of them, then it is $590. Generally you can buy two rx 570 for this price at newegg and ROI is like 6 month if you mine eth or zcash. However, if you use this stick to mine litecoin, the ROI will be like one year. Did I miss anything?

That is exactly what i did except I used a ssd. Everything works fine with 6 gpu. The initial set up is tedious though you need to add card one by one so a lot of reboots. After that, you should be fine.

Even they are the same model, one of them may not be able to handle the overclock. YOu need to set overclock to each of them and find out how high they survive.

It may well be a sick card. well it is not sick, it just cannot handle your overclock. Even they are all the same model, one of them may not be able to survive the memory overclock. Actually this is what happened to my rig.

1. read the log and locate which gpu has hanged first or error first. say cpu 0.
2. what I did is pressing 0 to disable GPU 0 in the rig.
3. watch if your rig is stable. If it is, congratulation, you found the sick card.
4. Try one by one till you find it.

or you can just disable watchdog in your bat file, set -wd 0. In this case, the sick card will stop but your other cards keep working. Now touch the card and feel the temp you will know which one is bad.

If you cannot find a card to blame, then you may need to reinstall the windows and update to the latest.

Hope this helps.

What is your psu? It may cause issue like this if it is not powerful enough.

In windows defender, add your miner folder to exclusion list.

Right now i am using xmr-stak-cpu-notl with no problem.

Makes sense. If watchdog can gracefully end all other thread it can then restart successfully...

I am not sure but when I turn on watchdog, the rig will freeze whenever it detects any issue. It tries to restart but fails and it just hangs there. If i turn off the watchdog, the rig is pretty stable. Maybe it is just coincident? Or there is a bug in watchdog?

Hi sp_. what is the hashrate on a 1070 in eth mining with your miner?

You can find this file in Claymore's miner folder and copy it to your xmr miner folder.

Anyone knows how to set solo mining using xmr cpu miner? or any gpu miner?

Thanks for the information. I used your settings and got same result!

Pool works!

xmr-stak-cpu-notls

458 h/s on 1600x with 6 thread
600 h/s on 1700x with 8 thread at 4gz

the issue is, when first started, run for a few mins, all of sudden all messages are like Result rejected by pool. have to restart the miner. now it looks fine.

Pool stat not align with miner hash rate

These are some very useful information and I totally agree with the windows issue conclusion! Thanks for sharing.

All of sudden my runner kept restarting. It has been stable in the last few days. Here is the log. Please help.

I am using 9.7, 5x1070

Could you kindly point me the direction to mine with one rig using both cpu and gpu? I cannot find any useful information...TIA

Any one can point me the direction to mine with one rig using both cpu and gpu? I cannot find any useful information...TIA

I can confirm that Asrock ab350 gaming k4 can handle 6 GPU. Mine is 4 480 and 2 570.
