F21a feedback - messed up overclocks

[treadpool]

Hello - I made the mistake today of moving to the F21a from F2f bios on my Gaming 5p. Until now, I've been overclocking at 4.25 and 4.37 very well at fairly low vcore - around 1.2. Now, with the same settings as before, I can't seem to get stability unless I bump up vcore long with a few others up a bit. Anyone else having similar issues?

That is right the first mistake was updating some thing that you didn't need too. The best thing to do is ask the people over on the OC part of the forum. You could go back to a older bios but you have to do it with boot-able USB drive. Put the bios on there and boot from it. You can't do it in the bios now. I think tells you that you can't go back.

Thanks. Tried booting from a USB to flash it like normal but no go. It's protected.

Apparently my board has DualBios, but there's no instructions on how to activate the backup. Anyone know how? When the backup is activated, does it replace the primary bios?

The thing is you can try this not saying it will work. But when you updated the bios by any chance did it do the backup too?

Here is a link on updating it back to the older bios.

Thanks for linking those. I'll give them a try later for sure, although I have a feeling the Rufus/bootable USB still won't work. Regarding if the backup was also flashed with the new Bios, I really hope not as that would defeat the purpose of a backup I think?

Called Gigabyte support and spoke to someone, which was nice. However, he suggested I should send the board in and have them re-flash it. Not gonna happen.  He also mentioned that using Qflash Plus should work, which seems to be a last resort. There's a special white USB slot in the back that takes a FAT 32 stick with the bios on it, does the work for you, and can be done without a CPU or memory installed.

I found some instructions here: http://gigabytedaily.blogspot.com/2014/09/gigabyte-x99-new-function-qflash-plus.html

Seem straight forward, but the video says to take out the memory but the written does not. The Gigabyte rep said to unplug the CPU power from the mobo - didn't mention memory. So, three different ways to do it I guess - will just have to pick one.

Nothing worked. Surprised the efiflash tool on a bootable usb in freedos mode even stopped the flash - telling me to get a newer bios version.

Looks like this bios screwed someone else also.
