i7 4770K incorrectly identified as 4771


New Member
My 4770K is being identified as a 4771. It is also showing odd clock speeds (bus clock is only 98 MHz instead of 100, MSI Afterburner correctly reads 100 MHz). Windows 10 and CPU-Z are both correctly recognizing it as a 4770K.

I figured out why, it correctly identifies the CPU if I disable Hyper-V. It seems you have a bug related to Hyper-V.

I didn't notice your post in the middle, but the fix for CPU name will handle this as well ;)
I don't have a fix for the lower bus clock, this seems to be a side-effect of Hyper-V (system running in VM).
