I have a strange issue on dz77ga-70k (bios 0063)
here is my specs:
windows 8 x64 as uefi boot
crucial 2gb XMP-1600-8-8-8-24 *4
MSI geforce GTX670 o.c. (as default video)
The problem is in bios behavior: if I uncheck the "legacy boot" and remain UEFI boot and then save and reload, the system will reload 3 times and then it shows black screen and after that monitor is switching on and there is my windows 8 start screen.
On system prefs I can see that the intel hd graphics 4000 is enabled (but i've disabled it in visual bios)
Then i reload and can't get into bios (Because of black screen!!!)
If I use back to bios button or jumper the system will reload 3 times again, then in bios I can see that legacy boot is turned on, intel hd 4000 is turned on, and memory XMP disabled!!!
We will proceed to escalate this issue to our research department for investigation and any updates will be posted in this forum. Thank for your patience and understanding.
