Z77 Extreme 4 + 3570k stuck multipliers

@wes93 - Great to hear you sorted it out yourself already! Is your Ethernet LAN still working OK? This (LAN MAC ID), and sometimes UUID is all Asrock puts in BIOS, so those would be all you possibly need to carry over into the stock BIOS.
Beta is OK to use if you want * edit - Ohh, hey, so this also fixed your 2 missing memory slot issue too? If yes, Great to hear! I’ve never heard this cause that issue too, but maybe others did not notice it when they had same problem

@Lost_N_BIOS
Thanks again for your reply!! :slight_smile: I love this forum!! :slight_smile:
1. Yes, no changes in my MAC address or UUID(Windows 10 remains activates and the MAC is the same, I have the rules in my router referred to the MAC address.)

2. Yes again after I have installed the bios in my mobo everything works again (I doesn’t have touched the RAM or CPU, just unplug the bios flash with CH341A and put back in the mobo)
