My miner started generating wrong shares

Posted: 12 Aug 2018 07:20 AM PDT

Firstly I have little miner based on H61 Motherboard with Pentium, 4gb ram, usb stick and Ubuntu. With it I have 3 Rx550s. I'm using and gpu pro drivers newest and I checked older too. My miner is xmr-mining crypto night coins.

Recently my miner started generating a lot wrong shares on miner side. It's about 75 percent good shares. On a pool side it's just lower hashrate.

I lower oc of my cards and gave them stock voltages. OC is really low.

I reinstall my system, driver, test older drivers, switch from WiFi to lan, and nothing helped.

On all my cards I used Polaris one click timing patch.

I don't have any more idea to what can i do more. But on my main pc nothing wrong happend it's hashing like it supposed.

How to clean mineral buildup on GPUs

TL;DR: I live near the ocean and have a window fan blowing onto my open-air mining rig. It appears that mineral deposits have been accumulating on the fins of the heatsinks, and I'm wondering how I should clean this off. I was thinking 90% isopropyl alcohol and scrubbing with a soft toothbrush, but suggestions are welcome. Thanks! Imgur Imgur Imgur Imgur

the power cable coming from wall to psu if its touching a usb riser cable, the gpu shows up as error or missing in both b250 menu & OS.

move the cable away... and it works. Im spend a good 6 months a day figuring out what was wrong and it was because of this... don't know if its relevant that its 240v or not.

Im learn it for u a First. So get to writing this down!
