RX 580 video card - very low hashrate error

[RoyalSpartan]

Hi all,

I have a problem.

I have a rig. It goes with four RX 580 video cards (ETH mining).

Three bring the 32 mh/s production properly. A piece produces just 8-10 mh/s. Phoenixminer and TeamRedMiner - the same effect.

I also attached two pictures to the post.

What could be the problem?

You push your cards to the limits… Thats why u have invalids… Try Core 1150 Vdd 850 Mem 2040 and amd tweak (tref 20 for samsung memory)…
