The last few days I've noticed that my clock speed does not decrease with voltage even on stock settings. I never used fixed OC so anytime I OC I always use dvid to set offset and it all worked flawlessly (vcore decrease and so does clock speed).

Now, any setting I use doesn't decrease clock speed when the CPU is not underload and voltage is decreased. Can anyone explain this?

p.s. Im on GIGABYTE Z77X-UD3H rev1.1 with F18 (latest non-beta)

Windows power settings. Board used and BIOS don't matter.

Also, enabling XMP can cause this as well.

Also check the usage of the CPU. Low voltage does not mean that your CPU is not being used. Some background process(maybe a virus) might be using the CPU which prevents the CPU to go to the low frequency states..
