Hello.
I've bought a G751JY with 16gb of ram pre-installed (M471B1G73DB0-YK0)(Samsung 2Rx8 PC3L-12800S-11-13-F3).
I added 16 gb of G-skill F3-1600 CL 11-11-11-28 1.35v PC3L-12800 8Gx1 SO_DIMM).
The first mounth all was quite ok, then I began to have blue blue screens every 20 min of game. It got worse and worse, till a point I could not access to windows anymore. I tried to pull out the new rams, and now it's all ok, no crashes anymore, never.
Why are this ram incompatible? They seem to be the very same as the ones pre-installed...
