Hey guys
new to the cryto game;
i managed to build my rig as follows:
GPU's: 4 x MSI RX570 4GB & 2 Gigabyte RX570 4GB
OS: windows 10 home
HDD: 128gb Kingston SSD
Motherboard: MSI H270 gaming M3
CPU: Pentium G4560
RAM: 8gb g.skill ripjaws DDR4 2400
PSU: Corsair HX1200i platinum
The situation is this:
I have 4 GPU's firing with a combined hash rate of 105 MH/s running relatively cool.
I have been stumped as to why i cant get the other 2 cards visible in Display Adapters.
After a bit of googling it i came across a post stating that it might be the OS so i decided to give Simplemining OS a try;
After mounting it on the usb and booting it it up i keep getting a frozen colourful screen; anyone can help me?
Many thanks

Have you flashed the latest bios to your mainboard? Have you changed the bios settings to support 4+ cards? (4g decoding, etc)
I also had problems with these boards, and I should allow IGP and use the integrated videocard to work fine.
