Gentlemen, I need some expert advice. My two mobo are biostar A55mh and A85S3 both with Kingston HyperX 1x8gb 1333 Mhz ram Non-ECC. I changed the 1x8gb ram with a Corsair 2x4gb ram 1600 MHz Non-ECC and both started blue screening during normal PC use. Per Biostar both mobos support 1600 and 1333 Mhz speeds. Bios updates were done. What would be the cause?
