I'd save the settings in a profile and try to switch to the secondary UEFI and see whether or not that solves it (there is an option for that)

it is sorta a good thing/bad thing, the overclock i use is using lower voltage with new bios, i am fine with dongle for now

So what BIOS 4901 does on my Hackintosh is to kill wake (Monitor stays black). With BIOS 4804 all is fine. Any ideas what it could be? Quite difficult to find out when you do not know what actually changed.

So some more elaborate release notes would be quite nice 😉

Please, can anybody tell us what actually has changed? Quite hard to debug a problem when you have no clue where to start looking ...

Like HiVizMan says, do not flash unless there is a real need.

And if I get issues, which is the best BIOS for the 3930K?

Should I stay away from the ones after the 4xxx series CPUs were released or would they be OK to use.

I stay with 4206 on the RIVE because any BIOS above that introduces issues such as I cannot access the RSTe OROM using cntrl>I. Also as you say, I believe all the newer BIOS are aimed at Ivybridge (4xxx series CPUs). I'll stick with HiVizMan's axiom: "If it ain't broke don't fix it". So, yes I stay away from all those released when Ivy became mainstream.

I'm not sure what you mean by "Does this work on R4EB?" With the exception of cap conversion on any NON RIVBE MB, all BIOS updates are cummulative-install just the latest one or whichever BIOS suits you for that board, but, flash only that BIOS released for that board.

4206 is the latest bios for SB-E processors after 4206 the bios's are optimized for IV-E processors. what he is saying is the newer bios for IV-E doesn't play nice with SB-E processors and the turbo mode while overclocking may not go past 4.2 GHZ when you have it set higher than 4.2 in the bios, which bios is best for you may be 4206 or 1404 or another version we can not tell you for sure. Some early bios versions were better with some types of memory modules, in my personal experience 4206 is a very good bios for 3930K or SB-E processors, 4901 is very good with a 4930K or IV-E processors but your experience may be different. You can flash back to an earlier bios on the RIVE using a USB stick and bios flash back method by renaming the bios file to ERALL so all is not lost if a new bios does not work well for your particular system
