Please share your experiences and issues with these bios versions. Most likely identical but with different settings with the beta driver having all cores synced (although you can't tell due to the bad descriptions and naming schemes).

ROG STRIX Z370-E GAMING BIOS 0605
Improve system stability
I'll share myself once I am done testing.
For the Z370-F, this is what you can read under this new 0605 (I wonder what is the logic for the numbering) BIOS:
ROG STRIX Z370-F GAMING BIOS 0605
Enable Intel(R) Speed Shift Technology.
Speed Shift Technology is supposed to be the replacement technology for Intel Speed Step Technology (EIST), that allows the CPU to adjust its frequency according to what the OS requests based on the load. With this new approach introduced with Skylake and Windows 10, the CPU can set its frequency itself, determining the right value for the need. The advantage is said to be the speed of the frequency switch (1ms vs 25ms says Intel) and the unparking of cores (35ms vs 100ms), making the system more reactive. I have never read any proof of the reality of this assertion, but if it is properly managed and does not induce any issue (even more audio popping for instance...), it cannot be bad.
Maybe someone from Asus (Mr Raja, please) could confirm ?
I would have tested by myself, but the current BIOS version (0420) of my Z370-F runs fine (except for audio crackling) and I am afraid to lose stability (such as RAM XMP compatibility). I am not sure it is possible to revert to an older BIOS version, some people on this forum indicate that no.
