Challenges and Solutions
1. PCIe Lane Allocation
The X99 platform’s 40 PCIe lanes enable efficient distribution across 7 GPUs. Bifurcation settings in the BIOS are critical to avoid bandwidth bottlenecks.
2. Power Delivery
- Use a 1200W+ PSU with 80+ Platinum certification.
- Split loads between dual power supplies if necessary.
3. Thermal Management
- Open-frame design reduces heat buildup.
- GPU undervolting lowers power consumption without sacrificing performance.
