Hey everyone, just tried upgrading my HP Pavilion G6T's RAM, and Windows refuses to start now. The laptop is running Windows 7 Home Premium 64-bit, and currently has 4GB, so I went to Crucial.com to get 8GB, used their scanner tool, which recommended this memory to me. Part Number: CT3326415 Module Size: 8GB Kit (4GBx2) Package: 204-pin SODIMM Feature: DDR3 PC3-10600 Specs: DDR3 PC3-10600 • CL=9 • Unbuffered • NON-ECC • DDR3-1333 • 1.35V • 512Meg x 64 • All the numbers seemed to match up, so I bought it. Said "Guaranteed Compatible" too. :confused Here's the scan results as well: http://www.crucial.com/systemscanner/viewscanbyid.aspx?id=4C62335431D926C3 After a bunch of failed attempts, I just threw my old RAM in, and after a Startup Repair, the laptop loaded up fine. Any ideas as to what happened or how I can successfully upgrade the RAM?
