My laptop config:
Windows 7 Ultimate 64-bit
6GB RAM DDR3 SODIMM 1600MHz (4GB * 1, 2GB * 1)
1GB Dedicated Graphics /NVIDIA
To upgrade RAM, I've 2 options:
1) Replace the existing 2GB module with 4GB (to make total RAM of 8GB)
2) Replace the existing 2GB module with 8GB (to make total RAM of 12GB)
Which of these 2 options is better?
And does it make any difference (or any impact) to have 4GB + 4GB (same size) as compared to 4GB + 8GB (different sized modules) in the 2 slots of the laptop?
what if I don't get the same brand of RAM as the existing one in my laptop?
