• Above 4G Decoding: Essential for multiple GPU setups
• SR-IOV support configuration
• Memory timing optimization

Performance Optimization Techniques

Achieving peak performance requires careful attention to several critical factors:

1. PCIe Lane Optimization:
   • Direct CPU-attached PCIe lanes for primary GPUs
   • Proper lane width configuration
   • Load balancing across available lanes
2. Memory Configuration:
   • Optimal DIMM population strategy
   • Memory frequency and timing optimization
   • NUMA awareness for multi-socket systems

Real-world Implementation Cases

In practical deployments, we’ve observed significant performance variations based on configuration choices. A recent implementation at a major hosting provider demonstrated how proper optimization can yield up to 37% performance improvement in GPU-intensive workloads.
