issues that I have with this board right now:
1. when legacy boot is disabled it is not possible to use the optical drive in windows. You also cannot boot a UEFI install from it.
edit: needs more investigation. it seems booting is possible sometimes but I am not yet sure what triggers it. it not showing up in windows could also be a windows problem but all solutions I've found and tried so far have been unsuccessful.
2. in UEFI boot mode no display port is available ,there do not seem to be DP drivers or so in UEFI.
3. sata boot drives get populated with UEFI capable drives but you cannot boot from from those. I currently have 3 entries in the list for only 1 ssd, it seems that as you move the drive from sata port to sata port the old, now defunct entry stays and a new one appears, there is no way to purge that list
edit: I found a way to clean the variables. Use bcdedit in windows to edit the nvram variables: Remove Duplicate Firmware Objects in BCD and NVRAM
4. when a DP to dual-link (active) convertor is connected to the thunderbolt/DP port, the computer shutdowns randomly. (This is also a problem with ivybrige but there the display (driver) only crashes and the screens goes blank no shutdowns.) this effectively makes this the second cpu from which I cannot use the integrated graphics. Once again I have to use external graphics.
edit:
it seems this also happens when the hdmi output is used and with a lower resolution (1920x1080) however the shutdowns are further apart.
I'm thinking there is some incompatibility with my monitor ? It's a HP LP3065, was quite a good and expensive monitor when I bought it. Never had issues with any ext GPU or laptops etc. only the iGP of ivybrige and haswell have this problem....
5. no option to go into the classic (AMI_TSE) bios, not really a bug but surely a big nuisance.
6. RAM timing cannot be configured, only a slider available that allows you to set every possible speed this board supports irrespective of the actual capabilities reported by the dimms.
7. memory speed slider cannot be set to default (jedec) speeds. Slider's left most value is 1333, when moved to the right then back to the left the lowest speed is now 1600
7. memory speed slider cannot be set to lowest available speed. if the slider is set to the left the speed should be 1333. It's on that speed after loading defaults. when the slider is moved to the right and then back to the left most position that position now corresponds to 1600. The only way to get 1333 back is to load bios defaults and then not touch the slider.
8. extreme voltages are enabled by default. also if this setting is changed manually to not allow extreme voltages and then the memory slider is touched, this setting is enabled again. Although the latter is not really a bug ( I assume it's b design) this is an unsafe action. At the very least a waring should be given that the extreme voltages will now be unlocked or even better the slider should not allow speeds that need extreme voltages and instead give a message that to get higher speeds the user should first enable extreme voltages.
9. cpu (thermal) protection (throttling) is disabled after loading bios defaults.
10. secondary sata controller when disabled in the bios still shows up in windows but devices connected to it do not.
11. dimm's embedded (JEDEC/XMP) profiles are not selectable
12. full dimm timings cannot be set manually
13. when UEFi is enabled and external graphics is used you cannot enter into the bios screen. (also not the efi shell)
edit: ok, so this is not a problem with the mainboard. The graphics card I'm using does not have a GOP vbios, only a legacy bios. I recently bought a R9 290 and it to seems to not have a GOP vbios. Mind boggling that this is not standard yet, it's a brand new design...
