I just bought a new memory ram(TwinMOS,2GB,DDR3,1333 MHz),I tested it using memtest and it passed the test without any error
but I have another memory ram (GEIL, 2GB,DDR3, 1333MHz) which I used it for 2 years and is kind of broken,I tested it using memtest and it contain a lot of errors but the thing is it also work standalone(but sometimes I get bluescreen in windows and I can not install any linux distro )
now the question is Can I use both of them on the same PC ? I'm afraid if I use them together,old memory broke new memory too.
