I have Samsung laptop RC510 with 4GB RAM (2x 2G 2Rx8 PC3). Latelly I wanted to change one of the 2GB for 4GB so I get 6GB RAM in total.

I got 4GB 1Rx8 PC3L RAM Stick but when I put it in my Laptop it stuck on loading Windows 8.1 and crashses...

So the question is: Can I mix 4GB 1Rx8 PC3L RAM with 2GB 2Rx8 PC3 RAM in asamsung RC510 ?

If yes is there a solution to pass my problem?

  • Does it work with only the 4GB stick? If yes, then it may not be possible to mix single-sided and double-sided RAM in that laptop. If no, then either the laptop doesn't work with single-side RAM sticks (unlikely) or the memory may be faulty - you could create a bootable USB stick with MemTest86 on it to test for the latter. – Andrew Morton Jan 26 '15 at 19:26
  • It Does not work with the 4GB 1Rx8 PC3L... It just comes to the loading screen of windows 8.1 and then the screen gets bugged and the pc turn off by it self – xThund3r Jan 26 '15 at 19:34
  • OK, it sounds like the 4GB stick is faulty (you can test it with MemTest86 if you want to be sure), so you will need to get it replaced. Really it is best to get a matched pair of RAM sticks (e.g. a kit with two 4GB sticks), so you might want to consider doing that if your budget allows. – Andrew Morton Jan 26 '15 at 19:40
  • tyvm for your help! Im going to buy new 4GB 2Rx8 to mix it with one of my old 2GB 2Rx8, thats better than going through all of this ^^' – xThund3r Jan 26 '15 at 20:03
