Hey everyone, I'm trying to squeeze more performance from my I5 750 as a final delay before considering a new machine. I swapped the original OEM CPU fan for a Cool Master Hyper 212 cooler and applied Arctic MX-4 thermal paste. Everything is properly installed and functioning. Following these recommendations: My configuration looks like this: I5 750 Gigabyte P55A-UD4 12GB DDR3 RAM GTX 780 Ti Cool Master 212 Hyper CPU Fan Arctic MX4 Thermal Paste I managed to reach 3.15GHz (170 BCLK/18x CPU ratio) with stable temperatures—average around 35°C during idle and 50°C under load. My settings are: Load-Line Calibration: Disabled Vcore= 1.264V (CPU-Z idle) QPI/Vtt/IMC= 1.149V PCH= 1.10V PLL= 1.85V RAM= 1.5V Power saving states disabled The issue begins when I attempt to push it higher to 3.2GHz, which causes constant restarts and BSODs. Increasing the voltage didn’t help. It seems 3.15GHz is the optimal sweet spot, but all the guides suggest anything below 3.8GHz should be manageable. I’ve tried adjusting voltages further: Vcore=1.40, Vtt=1.155, Vram=1.575, PLL=1.89 with PCH=1.10. But even with those tweaks, at 3.2GHz I still encounter BSODs. Any suggestions on how to proceed or whether staying at 3.15GHz is the best choice?

I tried to boost my I5 750 to higher speeds as a final option before buying something new. I swapped the original OEM CPU cooler for a Cool Master Hyper 212 and applied Arctic MX-4 thermal paste. Everything fits properly and is working. Following the recommended guides, I managed to reach around 3.15GHz with stable temperatures. However, when attempting to push it further to 3.2GHz, I encountered frequent restarts and BSODs. Increasing the voltage didn’t improve things. It looks like 3.15GHz is the optimal setting, while anything below 3.8GHz seems manageable according to the sources. I’ve also experimented with higher voltages (up to 1.40V, 1.155V, etc.), but they didn’t help. What should I do next?
