Picture of the 3 RAM memories

The laptop is a Toshiba Tecra A11-110 with an intel i5 processor.

I replaced the first RAM with the second one. The Windows begins to boot but ms later shuts down and the computer restarts again. Maybe the reason was that the second one was 1,5V. An analysis on Kingston website says these are the compatible ones, 1,35V. So, I bought the third one you see in the image. But the same thing happens: windows can't boot, it begins but quickly dies.

What could it be? Thank you.

Mixing ram voltages is not a good choice as in some cases it won't work, depending on motherboard. You will have to either undervolt the 1.5v to 1.35v or overvolt the 1.35v to 1.5v. You can do that in the BIOS in some motherboards, or maybe you can get another 1.35v memory instead.

  • I am just using the new one. – André Da Silva Dec 7 at 15:34
  • That's strange. Does the boot really begins? Does the Windows really starts to load? – Enrico Dias Dec 7 at 15:40
  • Yes, it does. The windows loading animation begins but instantly the whole thing restarts. – André Da Silva Dec 7 at 16:59
  • Have you tried the memory in another machine to make sure it works? Maybe it's a hardware problem. You can also insert a live cd and try to boot another OS to make sure the problem isn't with windows. – Enrico Dias Dec 7 at 17:54
