My motherboard will only POST correctly and boot when I have one stick of RAM in the first slot. When I have all three sticks of RAM in, I get post code 6A which isn't specified in the manual or online what it is. However, When I only have two sticks of RAM in the first two slots, I get post code "38" which means "Initializes different devices through DIM," According to the mobo manual. I don't have any idea what that means. I've tested all my sticks of RAM in slot one to ensure they are all working.
I googled the problem and only found one person who had the same problem; they said they were able to fix it by downgrading their BIOS to an earlier version. I've downloaded the early version of BIOS from the ASRock website, but when I put it on a flash drive or burn it to a CD, it isn't recognized as a bootable drive/disk. I don't have a floppy drive.
