email cleo see if there any updated bios for windows 8. pull battery and power from the unit and swap dimms or take out 1/2 the dimms and see if the error# stops or switches. use cpu-z see that both dimms are the same speed and type. vendor could have mixed dimms timmings in the laptop. if the dimms are 1600 speed check in the bios that intel xmp profile is turned on. wiht cpu-z read the spd info and see that the mb setting the ram timing up right.
I have the latest BIOS installed. I have 4 dimms the all are the same.. I'll try swapping them tomorrow..
