If there was a 1.60 Beta UEFI/BIOS, it no longer exist in the Beta download area. Besides the 2.30 Beta version, the only other Beta version is 1.70a.

Not long after several mother board manufactures, including ASRock, added the non-K over clock capability to some of their Intel chipset boards that did not normally support over clocking, Intel asked them to remove that capability in later UEFI/BIOS versions. I'm sure none of those manufactures ignored Intel's request, since Intel could choose not look favorably on them in future business dealings.

I don't know if the 2.30 Beta maintains the non-K over clock capability, but my guess would be that it does not.

If you value the non-K OC capability, I would not risk losing it by flashing to another, newer UEFI/BIOS version. As I recall, if you flash to a UEFI/BIOS version that removes the non-K OC capability, it also makes changes that permanently lock out the non-K OC capability. Meaning if you flash to a newer version and afterwards the non-K OC feature is gone, flashing the version that added that feature again will not bring it back.

Since I have never done this myself, I may be wrong. But given what I know about this situation, I would be very reluctant to try a newer UEFI/BIOS version.
