I'm having an issue with a new Z87 Extreme3 that i just purchased. It is not applying any changes that I set in the OC Tweaker section. I have tried setting the multi/vcore manually and I have tried using the preset profiles, but once I load Windows, the settings are not applied and my cpu is still sitting at 3.5ghz. Other settings in the BIOS are applying though and stick, like setting my HDD to IDE and no numlock on boot. I have been searching to no avail for what is causing this. If anyone has an idea, I'd appreciate it.
