Had a strange issue with this board. When I was in Windows I noticed the BBIOS and MBIOS LED's were alternating. Everything was running fine and no issues anywhere. So I powered the system off via Windows and when it booted up it booted using the backup BIOS, this time the BBIOS LED was solid while the MBIOS LED was off so that was ok.
As the backup BIOS was still on F2 instead of F3 I flashed that to F3 ok and booted into Windows. Again no issues, but just doing a simple restart via Windows caused the BBIOS and MBIOS LED's to alternate again
Again shut down via Windows powered up and this time it booted from my main BIOS and all my settings were where I left them and even the RGB LED colour settings were still saved.
No idea why this board will randomly decide to boot from either BIOS when there appears to be nothing wrong with either of them.
No issues otherwise and everything is running fine and is rock solid.
Can't seem to find what it means when the BBIOS and MBIOS LED's constantly alternate when everything is running just fine.
1800X is running stock and my RAM is also running stock at 2933Mhz via the XMP option.
Also coming from an Asus Z97 with a 4790K I have noticed my Samsung 850 Pro 1TB SSD performance in deep queue 4k is very bad on this chipset compared to Intel, plus doing a IOPS benchmark with Samsung Magician the performance is around 55k reads, 38/40k writes. The Z97 chipset did about 80k reads and 70k writes everytime without issues.
I am running all the latest drivers and even Windows 10 Pro has been reinstalled.
Here is a benchmark on my Z97 and 4790k system, check out the SSD performance, it's very good overall.

So looking around it's looks the the poor 4K SSD performance looks like it may be a chipset issue
http://www.tweaktown.com/articles/8073/amd-ryzen-ssd-storage-performance-preview/index4.htmlIntel, as expected, has the advantage across the board. The Intel platform, once again, lays waste to the Ryzen platform at 4K QD1.
