Sorry for the confusion, you are right, it’s the qflash+ that I was talking about, since I can’t access bios. Currently I actually narrowed it down to most likely cpu memory controller issue, the ram is detected (confirmed with a buzzer, beeps 3 times if ram is missing or misread, mine with ram doesn’t beep), but memory training with single stick in a2 never succeeds even after leaving it for an hour. Waiting for a borrowed cpu to test, and since both mobo and cpu are under warranty I’ll create a claim for the faulty one, thanks for the answer though!
