I'm trying to OC my i5 2500K to 4GHz but the OC doesn't seem to show up in Windows.
In previous BIOSes I was able to OC by changing the CPU ratio and disabling Turbo Boost (as that tends to interfere with overclocking). With BIOS 3203 I can change the CPU ratio but I get no change when I boot into Windows (both AIDA64 and CPU-Z report that my CPU is running at the stock speed of 3.3GHz).
Am I doing something wrong or is the BIOS a dud? I notice that there's a new BIOS version out (3304) but haven't updated yet.
