- **--cpu-memory-pool=32**: 14,000.1 H/s
- **--randomx-1gb-pages**: 14,612.1 H/s (failed to allocate 1GB pages)

### GPU Mining Attempts

#### TeamRedMiner (AMD GPU Miner)
- **ROCm container**: Failed - "Failed to list OpenCL platforms"
- **AMD OpenCL container**: Failed - "unknown device name: 'gfx1151'"
- **Issue**: RDNA 3 GPU (gfx1151) not supported by TeamRedMiner v0.10.21

#### lolMiner (GPU Miner)
- **AMD OpenCL container**: Detected GPU but "Unsupported device or driver version"
- **Vulkan containers**: No OpenCL support
- **Issue**: RDNA 3 GPU not supported by lolMiner v1.82

## Optimal Configuration

**Best performance achieved**: **14,728.4 H/s** (22.7% improvement over original)

**Recommended setup**:
- **Container**: `amd-strix-halo-llama-rocm`
- **Threads**: 32
- **Memory pool**: Default (no memory pool parameter)
- **Command**: 
```bash
./xmrig -o pool.supportxmr.com:443 -u bc1qjn4m6rmrveuxhk02a5qhe4r6kdcsvvt3vhdn9j -p NUC --tls -t 32
```

## Memory Allocation Analysis

### Current GPU Memory Usage
- **Allocated**: 96GB VRAM
- **Actually used**: ~1.6GB
- **Wasted**: ~94GB

### Impact on Mining Performance
- **Reducing GPU memory allocation**: Would free up significant RAM for CPU
- **Current CPU memory usage**: ~12-13GB during mining
- **Potential improvement**: Could potentially improve performance by 5-10% with more RAM available

### Recommendations for Memory Optimization
1. **BIOS/UEFI Settings**: Check if GPU memory allocation can be reduced in BIOS
2. **Kernel Parameters**: Consider adding `amdgpu.gttsize=32768` to reduce GPU memory
3. **Current kernel params**: Already has `amdgpu.gttsize=131072` (128GB) - could be reduced

## Notes

1. **GPU mining not viable**: Current GPU miners don't support the AMD Strix Halo RDNA 3 GPU (gfx1151)
2. **CPU mining optimized**: Container environment provides better performance than native
3. **Thread optimization**: 32 threads provides the best performance for this CPU
4. **Memory usage**: ~6.5GB RAM used for mining with 32 threads
5. **Memory pool**: Default settings work best - manual memory pool configuration reduces performance
6. **GPU memory waste**: 96GB allocated to GPU but only 1.6GB used - significant optimization opportunity

## Future Considerations

- Monitor for GPU miner updates that support RDNA 3 GPUs
- Consider trying newer versions of miners when available
- The ROCm container provides the best environment for CPU mining
- **Memory optimization priority**: Reduce GPU memory allocation to free up RAM for CPU operations
