I'm pretty new to mining. I just assembled my first rig with the following specs:
- AsRock H110 BTC+ Motherboard
- Kingston 4GB DDR4 2133MHz
- 8x AMD RX 470 4GB
- 2x Corsair RMX Serie RM1000x
- Windows 10
- Claymore Miner v10.0
- Crimson ReLive Edition Beta Drivers
Now I face the following problem: As long as I run the Claymore miner with up to 7 GPUs, everything works very smooth and I get 28MHz on every card. When I start the miner with an 8th card, the whole computer freezes after 1-5 hours. I believe to have witnessed a drop on GPU #7 hash rate before the freeze but I'm not 100% sure.
What I tried before:
- Changed the cards / PCIE slots to make sure I don't have a corrupt card
- Started two claymore miners having each work with 4 GPUs
- Changed from (4 GPUS + motherboard) on one power supply and (4 GPUS) on the other power supply to (3 GPUS + motherboard) and (5 GPUS)
- Reinstalled the drivers and used different versions (16 & 19)
Does anyone have the same problem and found a solution?
