So I overclocked my 6500 to 4.19 MHz on gigabyte z170 k3, it worked perfect for 2 days and I desided to oc it a little more, at 4.4 after booting in windows error occurred and I rebooted to 4.2 and it showed same error, windows didn't boot at any frequency except base without oc. What do I need to do to oc it again?
