I built the gpu mining. Used RogStrix Z490F Gaming Motherboard (because difficult to find out in local) and 4 GPU (all RTX3060).
The Motherboard have 2 slot PCIe 3.0 x16 and 2 slot PCIe 3.0 x1.
Note : I put the pcie riser usb x1 to x16 on the PCIe 3.0 x1 slots
The result:
Slot No. 1 (PCIe x16) hashrate 47 Mh/s
Slot No. 2 (PCIe x16) hashrate 47 Mh/s
Slot No. 3 (PCIe x1) hashrate 25 Mh/s
Slot No. 4 (PCIe x1) hashrate 25 Mh/s
Why the RTX3060 performance only +/- 50% on Slot No. 3 and No. 4? compare the No. 1 and No.2 performance
Please advise me for this bottleneck
Thank All of you

What’s your CPU?
Bottleneck could be the number of PCIe lanes supported by your CPU. Try setting your PCIe slots to x1 gen1 in your bios, which will still provide enough bandwidth for mining.
Important Sidenote
You should not be mining ZEC with GPUs. At current difficulty levels you will not break even on electricity costs, as the network is dominated by ASICs. Try mining ETH or another GPU-friendly coin instead.
