Hello, I have a Lenovo G550 with motherboard NITU1 and chipset PM45 rev07. The BIOS version is 18CN44WW (V.2.53) dated 19.04.2010

My question is , can I install M471B5173Qh0-YK0 4GB 1Rx8 PC3L12800S-11-12-B4 RAM in it? (I have 2 x 4gb of the same)
I'm asking because when I install them my screen is black ?

Can I have a link to a good BIOS update in a modified version please?
Tomek.

PC3L is the problem. This is an old motherboard that supports standard DDR3 memories with 1.5Volts power supply voltage. The newer DDR3L or PC3L are powered by 1.33V. "L" stands for Low voltage.
Find DDR3 1066 or 1333MHz memories (not 1600MHz), and they will work.
