My 11th gen Intel Core i5-11400 2.70 GHz keeps on getting between 0.78 to 1.14 GHz and I’ve tried MSI Afterburner I’ve tried turning off BD PROCHOT using ThrottleStop, but nothing is helping it get to higher speeds which also with turbo (which is built into the CPU) it can reach 4.50 GHz
MSI afterburner has nothing to do with CPU.
What are your CPU temps at?
