Title: 6th GPU not working (Radeon RX 580) Post by: jere on January 04, 2018, 10:58:37 AM Hi,
I have 5 Radeon RX 580 GPUs dual mining mining with claymore on Windows 10 using the blockchain driver (17.30.1029). The cards been stable for many days. However, if I add a 6th GPU (I have tried with a RX 480 I have) windows only detects 5 GPU:s (one of the 580:s that works, is not detected). I have tried with a couple different risers. I have decent quality 2 PSU:s (1000w corsair + 750w seasonic). I have measured my power usage from the wall, and the PSU:s are not close to maxing out (at about 60-70% load). All the PCI-E risers are powered from the 1000w PSU) The motherboard I'm using is Gigabyte H110 D3 A. Using 4gb RAM. Any pointers to what I might be doing wrong? |
