I have the following system:
Asus P5Q Pro - last bios available installed
4Gb RAM (2GB + 1GB + 1GB + empty slot)
5 cards - 4 x RX 480 8Gb and 1 x RX 570 8Gb - all with custom bios with all timings and speeds already written in bios
I tested it and here are the results:
Windows 10: this system is stable and I can mine for weeks.
I am able to boot and mine with only 3 cards
With 4 cards I am able to boot only in maintenance mode+disabled gui. The moment I start mining only 3 cards get hash rate, the 4th has zero hashrate and shortly the miner crashes.
With maintenance mode disabled it will not boot with 4 cards and gets stuck at “Starting agent screen”
With 5 card it will get stuck at “Starting agent screen” regardless of maintenance mode setting.
Do you guys think it has something to do with the odd memory configuration (2+1+1).
Maybe if I buy 4 x 2gb sticks it will solve this problems?
Windows does not care about this and it is perfectly stable mining with all 5 cards.
Or maybe some other reason?
Thank you in advance,
