I tried from 2301 to 2603 bios versions but the same error comes up everytime with all bios versions. When I try to update it, it gives me a popup (in the bios through EZFlash) 'Security verification failed', and it wont update. SO here is the 'MAIN' problem, I tried to update/downgrade the bios to check if the memory checking bug remains or not, but guess what, I cant! To me it looks like it has a modded bios on it, because if im right then this is NOT a ROG Asus motherboard, but it still has the Asus ROG logo when it boots, I reseted the bios through bios and with the cmos pins as well just to be sure it is reseted, and it still has the ROG logo (I thought it is just a modded logo but it turns out that it isnt).Īlso when I set something in the bios, like the ram frequency, it every time resets it to its defaults because of the memory check I guess (other settings remain to its modified values if I remember correctly). When it boots it ALWAYS checks the memory, meaning that it is always needed to press F1 to go to the bios (It does not checks the memory after reboot, just when the PSU switch is flipped for the first boot) and then to leave the bios otherwise it wont turn on.Īnd it also starts as soon as I flip the PSU switch on! (this is very odd, there is no setting in the bios that indicates to boot right after it has power.) Hi all, I have bought a 'new' motherboard for my sister' pc, (Asus M5a97 evo r2.0)
