It's a known issue and seems like Gigabyte fixed the issue with F51 BIOS for Hynix version.
The problem is, flashing utility will not flash to F51, spitting out errors.
It's frustrating that fix is right in front of me, but I cannot flash it. I followed the guide, but wouldn't work. I tried to open up a ticket but the website wouldn't let me.
It's driving me nuts!
