Title: Problem with 3rd GPU Post by: Cereberus on May 14, 2017, 11:18:15 AM Lately I am having a lot of boards with RX 480 8GB from sapphire. In one of them I have a problem now. The three cards were working in Nicehash. Now the 3rd one does not start anymore, only the first two. The third one is on a riser or PCIex8 I don't know how Nicehash count cards but any suggestion how to make it back to work.
Plug out and plug in maybe ?

The 3rd GPU used to work correctly for 2 days and now it stops when mining in Nicehash. I am trying to figure out how to use Claymore 9.3 miner as I am reading it is the best but things are not looking that good so far. I will try to SWAP the cards as you say and let you know.

I would just make sure you have the correct amd app sdk files or just reinstall amd card drivers. im using amd app sdk 2.9.1 because 3.0 wasnt working for me, that might be your problem. if the 3rd card isnt running power wise it might be you psu isnt pushing enough watts or you need to switch out the 6pin pcie power connector.

If the fanspeed could get raised a little? If not, reduce the memory clock values. Temperature on 3rd card higher than those other twos? Place the coolest running card into the most probelematic slot. |
