I have bought a 2 sticks of memory 2GB each DDR3 PC3-10600 DIMM/1333MHZ 2Rx8 1.5v. It's identical to my current memory stick for one exception the voltage is slightly higher. The one I have now is 1.3v. When I swap the memory sticks for new ones I hear a long continues beep and have to shut down the computer to stop it. I have read that I clearing CMOS might help with that, but don't know where CMOS is. Thank you for help and attention.
