Re: Serious UEFI issue with DZ87KLT-75K

update:

 

for now this is the updated bug list for this board:

 

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.

 

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 defunc entry stays and a new one appears, there is no way to purge that list

 

4. when a DP to dual-link (active) convertor is connected to the 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.

 

5. no option to go into the classic (AMI_TSE) bios

 

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 most left value is 1333, when moved to the right then back to the left the lowest speed is now 1600

 

8. extreme voltages are enabled by default

 

9. cpu (thermal) protection is disabled by default

 

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 profiles are not selectable

 

12. full dimm timings cannot be set manually
