 **Known Limits:**
 - **1000 MHz:** Minimum safe frequency on stock kernel
-- **2000 MHz @ 1000mV:** Safe for all boards
-- **2175 MHz @ 1025mV:** Safe for most boards
-- **2230 MHz:** Maximum with kernel patch, requires cooling
+- **2000 MHz @ 1000mV:** Safe starting point
+- **2100-2175 MHz @ 1025mV:** Works on many boards, test thoroughly
+- **2230 MHz:** Maximum with kernel patch, requires good cooling
 
 !!!warning "Overclocking Risks"
     Overclocking can cause instability, crashes, and potentially hardware damage. Always monitor temperatures and test thoroughly.
