Your computer takes:

DDR3 1600 MHz (PC3-12800) CL11

PC3 is standard voltage (1.50V) where PC3L is low voltage (1.35V) - A system which requires PC3L cannot support PC3 RAM. PC3L RAM will work in a PC3 based system as it will run at the standard voltage and will inter-operate with PC3 RAM within the system.

computer beeps twice.....pause, beeps twice.....pause and won't boot,

2 beeps means no ram detected. Make sure they are seated properly.

Just install one and see if it boots, then add another...
