Hello 

 

I have E5450 with default 8GB of RAM. I wanted to extend it to 12GB with my old 4GB from Kingston. Problem is that each time I insert the new 4GB - no matter which slot I choose, or if I insert it together with the 8GB, no matter if it's 8GB in slot A and 4GB in B, or the other way - laptop runs for a few seconds, the fan runs at very high speed and then the laptop turns off. What is the problem? Below are specs of the 4GB RAM.

Kingston 4 GB SO-DIMM DDR3 1600Mhz CL11 ValueRAM (DDR3, SO-DIMM, freq.: 1600 MHz, timing: 11-11-11)

My regards. Thanks for any help!
