Pinmod safe for Z75 Pro3?

Had stable OC for years, got a wild hair on my ass and went to go change memory timings and found bios was a bit fucked up. It got ‘stuck’ on the OC settings it was set for, couldn’t even revert to defaults! So I reflashed the bios in attempt to fix it and lost all OC options.

Googling finally got me here, but nothing I’ve tried has worked at all, absolutely nothing from This Thread nor this thread has worked.

Finally stumbled across this thread, guy had similar issues and possibly fixed it via pinmod. The chip on my board (ALC892) has the same pins (1,5) as the ALC269 pictured in the thread but I am unsure if the procedure is the same for the 7-series chipset as the 6 series…


[Edit] Also if it is “safe”, can I just leave a jumper there in case the fuckup happens again?

The procedure has been the same since 2010 so yes it works and it is safe. The lock bypass applies to one boot only (the one with the two pins shorted) and resets back after the next restart. No you cannot leave the two pins shorted all the time. Instead, if you really want to leave the system in a Manufacturing state, you can rewrite the Flash Descriptor with the locks disabled at offset 0x60 - 0x70 like this:

Thanks, issue fixed and now I can OC again.
