Except 2x cold boot with additional loading time everything works fine of course.. After i tried almost everything including clearing cmos with battery removal, changing all possible bios options and trying different hardware(memory, psu+ front panel) and etc and etc... now i can be 99% sure the problem is motherboard sending voltage to ram too early (when its not enough or too much) which cause second boot with full memory testing (voltage, frequency, timings...) - if you set manually frequency,voltage in uefi it loads fine in hot reset but not cold one.. yes i tried few different memories (and they are compatible with this board on their official site) !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! which means board is ignoring "power-good" ("PWR_OK") signal from psu... (i tested with few different psu (even pricey one) - and they all worked fine with more than 5 different motherboards+memory before) the question is can you fix it via new bios/uefi (i think even simple additional ~1sec wait before memory POST test should work) and how soon , or its completely hardware problem - and all your apollo lake boards are that faulty??? and yes maybe there is some memory which will work better - but fix should be pretty easy for almost all memory, right??? PS: please send it to your bios/uefi coder... bcs your official support is.... |
