Here are modified bioses for Crosshair VII boards, which include the new SMU 46.49.0 release that improves boost behavior / margin on 3000-series CPUs.
Do note that these are totally untested, rebuilt bioses. Despite I fully expect them to work, there is no guarantee what so ever that they actually do.
Also since the bioses have been rebuilt, their original signatures allowing them to be flashed using official software (e.g. EzFlash) tools are invalid. Because of that, they can be only flashed in using the Flashback feature
In case they do not work or introduce some kind of an issue, you can revert to original bios by using Flashback function.
Also note that these bioses ARE NOT based AGESA 18.104.22.168ABBA code revision, as the whole code base has not been upgraded (only the SMU firmwares).
Therefore the behavior might not be identical to true 22.214.171.124ABBA bios builds.
Naming: Official bios build, M = Modification, FI = 4649 (ASCII)
Crosshair VII Hero 0002M-FI

Please let me know if they work or not, so that I can take them down if they're not working.
