X99E-ITX/ac BIOS version for Windows 10

   Just following up, the point of the P1.20E BIOS is to provide PCIe bifurcation, so you could split the 16x into two 8x lanes if you wanted to run multiple GPUs.  I'm curious as to whether this feature made it into the 1.40 BIOS

	The Clock Watchdog Timer is really an Intel service that runs in Windows. It is related and used with the Intel Extreme Tuning Utility, and the Intel Management Engine software. I noticed that the Clock Watchdog Timer was not running on my Win 10 installation on a different ASRock X99 board, but I don't think that is a UEFI/BIOS issue. IXTU tells me that the Clock Watchdog Timer is not running, which must be a failure caused by an interaction with Win 10. But I see this as being a purely Intel issue. The beta UEFI for you board is NOT the one in the Win 10 list. Given the minimal description of all the UEFI versions, how can we tell what changed? Since I don't use your X99 board, I have no way of trying the beta UEFI, or explaining any special settings it needs. I can't believe it is very or at all different in the options and settings available, but the underlying changes seem to be affecting your system. If you're using any Win 7 drivers or ASRock programs with Win 10, don't. Try the Win 8.1 drivers and programs if a Win 10 version is not yet available.

	As a follow-up to my earlier post, I made myself the guinea pig and installed the P1.20E BIOS version. I do not recommend it. My computer became unstable and it was hard for me to get it to start consistently. I had to do a CMOS reset at one point to get it to post. I would not be comfortable installing that BIOS version again unless someone can explain what it does and if any special settings or procedures are required. I reverted to the P1.20 BIOS version and after going in the UEFI I see that version 1.20 is also labeled P1.20.

	I have the X99E-ITX/ac and have upgraded to Windows 10. I have had a few crashes due to Clock_Watchdog_Timeout or the WHEA BSOD. I have my CPU overclocked and it was stable in Windows 7 at the same speed. I have increased the vcore a little and have not yet had a crash since doing that. I found this page on the internet today listing BIOS versions for ASRock motherboard for Windows 10: http://www.asrock.com/microsite/Win10/ It says to use BIOS version P1.20. I currently have version 1.20 installed and I see P1.20E on the 'Beta Zone' part of ASRock's website. Does anyone know if P1.20 is the same as 1.20 or if it's the same as P1.20E? I'm tempted to update the BIOS version to P1.20E but I don't know if that will do anything and also it's a beta so it may be less stable. On another note, does anyone know if BIOS version P1.20E may address the wifi issue people have been having with the Broadcom wifi/BT module? It says "Improve PCIE compatibility" but I'm not sure what that really means.
