[SOLVED] CPU bios update f4 to f15

[eurotruck1516]

Hello everyone, I uppdated my bios from f4 to f15. I was wondering is f15 better or worse than f4? Should I change it back to f4 or stay with f15? Will it do bad something about my hardware or won't?
PC Specs:
I5-8600k
Geforce gtx Msi 1060 gaming x 3gb
kingston hyperx ddr4 8gb 2666mhz (1 ram)
Gigabyte Z370 aorus ultra gaming rev 1.0
cooler master water cooling ml-240
650watt psu
Mostly I play games and watch movies on this pc.

Well given a newer bios version is usually better than the older version, i would see it as a downgrade to go with an older bios version.

If you are not having issues with this new bios version, i would leave it.
