| RISKS & WARNINGS | |
| Bricking Risk | ⚠️ HIGH – Flashing modified BIOS can permanently damage or “brick” your graphics card |
| Warranty Void | ⚠️ Modifying BIOS typically voids manufacturer warranty |
| Hardware Damage | ⚠️ Incorrect voltage/clock settings can cause permanent hardware damage |
| System Instability | ⚠️ Can cause crashes, artifacts, system instability if configured incorrectly |
| Recommended Precautions | • Always backup original BIOS • Research thoroughly before modifications • Have dual BIOS switch available (if equipped) • Start with conservative settings • Use appropriate flashing tools (ATIFlash/AMDVBFlash) |
| COMMON USE CASES | |
| Cryptocurrency Mining | • Optimize memory timings for better hashrate • Reduce power consumption • Improve efficiency (especially Ethereum mining) |
| Overclocking | • Push GPU beyond factory limits • Achieve better gaming performance • Fine-tune voltage/frequency curves |
| Undervolting | • Reduce power consumption • Lower temperatures • Quieter operation |
| BIOS Modding | • Convert mining BIOS back to gaming BIOS • Cross-flash similar GPU models • Enable locked features |
| Troubleshooting | • Fix corrupted BIOS • Restore factory settings • Repair bricked cards (with hardware programmer) |
