Multi-GPU Mining Setup: Tips for 2, 4 & 8 Card Rigs

Building a multi-GPU rig requires careful planning. Here are the essentials:

• Motherboard: Needs enough PCIe slots. Use risers for spacing.
• PSU: Total wattage = sum of all GPU power limits + 150W for CPU/mobo. A 1250W PSU handles 2-3 high-end GPUs.
• Cooling: Leave space between cards. Open-air frames work best.
• Software: Use CUDA_VISIBLE_DEVICES to assign each card, or run separate miner instances.
