Dear all,
I am having issues with XMP profiles on the latest BIOS version 1105 on my ROG Maximus Extreme.
Previous version 1005 (and below) were OK.
When enabling XMP (1 or 2), my RAM OC settings are properly detected, and I can save settings OK.
But after having saved the settings, during each boot before POST, the motherboard powerdown itself and power back up. It does it ~4 times on cold boot (ie: when power is switched off and outlet disconnected for more than 10 seconds). Only after these 4 cycles do I get a proper POST with the "press F2 to enter bios settings".
It's as if the motherboard has issue POSTing properly once XMP is enabled.
When entering bios after these poweron/poweroff cycles at boot, I discover that some BIOS settings are changed from auto to fixed values (such as CPU VCCIO).
Sometimes even my XMP values are overriden (such as the frequency, for a lower setting).
I even tried to manually set in the bios the RAM parameters of the XMP profile (and disable XMP, since I had already punched-in the proper settings in the bios), but the behavior of several poweron/off cycles at boot remains.
I'm a bit puzzled on this behavior, that only occurred a few weeks ago when upgrading to the 1105 BIOS, which claims to feature "Improved DRAM compatibility" in its changelog.
As all was working very fine before the Bios software upgrade, I'm not convinced this is an hardware issue.
Is anyone else also experiencing these issues?
What would be your recommendation?
