I'm going to upgrade my
Fujitsu Lifebook A512 (
Intel Core i3)
4GB 2Rx8 PC3L-12800S-11-12-F3| Works fine
4GB 1Rx8 PC3L-12800S-11-13-B4| With this
RAM(alone or with the original) the computer doesn't start, with all the lights turned on except
HDD, Num & caps lock
Basically the new RAM should be compatible with the motherboard (
Where is the mistake?
13-B4 instead of
12-F3 or the new
RAM is broken?
