    Z690 a-Gaming D4 strange cold boot behaviour

    Hello. Here is my problem - when i switch my pc on after it was completly turned off it double boots, i mean it starts for a sec then shuts down, then starts again and then works fine. When i reboot, it reboots normally. Here is what i found, whats causing it - first i thought its smth with memory oc, but no its not - setting all settings to auto (I mean loading with jedec Profile) still double boot. Then i set SA voltage to auto still double boot. So only Dram voltage left - i changed it to auto - and pc boots normally. I found out that if i put dram voltage higher then 1.35 (all other settings set on auto, and memory loads with jedec Profile) double boot happens on fresh start, only fresh start not restart. So the question is what can lead to such strange behaviour or maybe is it normal?

    Small remark - if my memory is overclocked double boot doesnt reset it to default values it boots and works and passes all tests at oced settings. Also i should mention that the same behaviour stayed after i updated from 0807 bios to 0901.

    P. S. Sorry for my english.
    P. P. S. Have a great holidays!
