- Vaio SVE 11135CXW Laptop
- 750GB HARD DRIVE
- 4GB RAM Samsung 2GB 2Rx8 PC3-12800S-11-11-B2 DDR3 1600
I wish to upgrade to 8GB, I have found a similar Samsung card, Samsung 2GB 1Rx8 PC3-12800S-11-11-B2 DDR3 1600. The difference being that the existing card is 2Rx8 and new card is 1Rx8.
Are they compatible and if used together will they cause any instability or other problems?
