- Changed default value for Round Trip Latency to Enabled (does it mean “RTL Optimization” back to Enabled???)
- Improved electrical overstress protection in the voltage regulator circuitry. (whatever this means)
- Updated processor support. (whatever this means)
I would like a steer from Intel as to whether it is safer to upgrade BIOS now to prevent WHEA (if this is what is included in the BIOS release - still not clear - it sounds related but the release does not mention WHEA at all).
We do not know the potential risk of running an older BIOS - if Intel can advise under what circumstances WHEA is likely to occur we can at least try and make an informed decision to either change some configuration on our current BIOS to limit the potential for WHEA damage and upgrade once the dust settles or upgrade now, if there is nothing we can do to under an older BIOS to stop WHEA damage.
Since Intel has said in FAQ for SY.pdf that they are working to solve the WHEA problem I guess that this BIOS is a step in that direction.
I jumped at the possibility to update to BIOS 42.
Hope to see soon an update also in the above mentioned document.
NUC6i5SYH running for more than 5 hours on BIOS 42
I upgraded to 0042 from 0039 this morning via Windows EXE upgrade method. I've installed every BIOS update this way.
Upgrade went fine. It seems like it boots up a little quicker now, but that's completely anecdotal. I haven't actually timed it. I've rebooted and shutdown about 6 or 7 times here to test, no POST errors, boots up great every time.
They did re-enable Round Trip Latency (I had it disabled).
My NUC has been pretty stable, I've only had one bad system crash and I think it was due to a Windows update.
Will post back if I start to encounter any issues.
I have an NUC6i3SYH running 24/7 since 15.03.2016 without any problems so far.
I have it at balanced mode with "cool" preset. its quiet enough

I use ethernet only, dont need the wlan, but i have it on in bios and tested it in ac mode.
Windows 10 Pro and always up to date drivers. I check the intel page every few days.
On day1 i installed Bios 36. Upgraded to 39 when it came out and today i installed the version 42.
Until now, all is good. And i really hope it will be so in the future. Then i like this little, enegy saving cube.
Yes. Grab a blank fat32 formatted flashdrive. Copy only the SY0042.BIO file to it. With the NUC powered off, plug the flashdrive into any port (I generally use the front blue port, but shouldn't matter), and power on. Don't touch anything for 10 minutes! It should only take about 5, but better to be safe. If it doesn't reboot on it's own, you can go ahead and power-cycle it yourself after the 10 minutes and you should be good to go!
Linux is not a supported environment for BIOS update. Without going into a long, exhaustive explanation, the trick that is used to support BIOS installation in the Windows environment does not work in the Linux environment (nor will it ever). Your choices are to use Windows, DOS or the BIOS (F7).
