I'm hoping someone could help me. I received my 8GB (2x4GB) DDR3 PC3-10666 today to upgrade my HP DV6-2154ca from 4GB (2x2GB) DDR3 memory.
I installed them successfully and even the BIOS did show 8129MB of RAM and showed the RAM modules placed (note: showed serial numbers as 00000.. and empty manufacturer), but as its booting up it gets to a black screen with 8 blue dashes at the very top of the screen, and holds there. I chose Startup Recovery several times, takes so long, and still doesn't fix the problem. I switched back to the 4GB, got the same screen, then a BSOD (blue screen)
