I have a weird behavior with the PHI algo mining the LUX coin.

Mining with 8 1080 ti I get 250 Mh/s hashrate

And mining with 9 1080 ti (adding one) I still get 250 Mh/s hashrate...

All of the cards got a lower hashrate with the 9th around.

Does anyone have any advice ? Rig is TB250 PRO, 4Go DDR4 with 64 Go swap, Intel G4400 and 9 MSI 1080 ti.

Did you run 9 GPU on Windows?
