+# Mining Performance Tests in Containers
+
+## Test Results Summary
+
+### Original Performance
+- **Original xmrig performance**: ~12,000 H/s
+
+### Container Performance Tests
+
+#### 1. ROCm Container (`amd-strix-halo-llama-rocm`)
+- **28 threads**: 14,084.2 H/s
+- **32 threads**: 14,728.4 H/s ⭐ **BEST PERFORMANCE**
+- **31 threads**: 14,233.6 H/s
+
+#### 2. AMD OpenCL Container (`amdopencl`)
+- **28 threads**: 14,020.0 H/s
+
+#### 3. Vulkan Containers
+- **amd-strix-halo-llama-vulkan-amdvlk**: No OpenCL support
+- **amd-strix-halo-llama-vulkan-radv**: No OpenCL support
+
+### Memory Allocation Tests
+
+#### Current System Memory
+- **Total RAM**: 30GB
+- **GPU VRAM allocated**: 96GB (only ~1.6GB used)
+- **Available for CPU**: ~21GB
+
+#### Memory Pool Optimization Tests
+- **Default (no memory pool)**: 14,728.4 H/s ⭐ **BEST**
+- **--cpu-memory-pool=-1 (auto)**: 14,679.9 H/s
+- **--cpu-memory-pool=16**: 14,059.0 H/s
+- **--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
