Downgrading Crosshair VIII Hero

Can I do this using USB bios flashback? I upgraded to 4201 or whatever that doesn't seem to be on their site anymore, now I see they have 4402 security fix bios, but when I upgraded the bios I didn't know about the performance loss past bios 3801.


If I put 3801 on a flash stick and name it C8H.CAP will I be able to downgrade with bios flashback?


I'm hoping I could get better bench scores and possibly get my fclk to run higher on the lower bios. Though I wonder if I should upgrade to this new security fix bios...

you should. sometimes in patch notes it'll say that you can't downgrade once updating but I don't see anything specifically mentioned.
