I bought an i5-4570 @ 3.2GHz paired with an Gigabyte H87-HD3 about 1.5 years ago for my gaming rig.
A few days ago I noticed that the PC info, BIOS, CPU-Z, GeForce Experience show up an i5-4670 @ 3.4GHz.

Now one would normally think that they just send me the wrong CPU.
But in the past it actually showed me the 4570.

Does anybody know what could be the cause of this?
Maybe motherboard or BIOS problems?
Should I even worry about it?
