Problem:
Computer always display cmos checksum error and the code is c1-c3 being displayed


Solution:
Most of the solutions describe here are valid for most cases, but i think there is a case where i dont see anyone mentioning it: not enough voltage for ram. Some brand of ram require more voltage than most and if they do not received enough, cmos will complaint and display the error code. By default, most motherboard voltage come preset around ~18. If you go into bios and change the voltage to 19.5, then it should stop complaining

hope this help
