I have a Toshiba Satellite C855 with two RAM slots and one 4GB Ram.

I bought a new RAM but it will not fit in slot 2. I took out the old RAM from the slot 1 and put the new one and it fits without a problem. Both the old and the new RAM will not fit in the slot 2 though. I tried with 30 degree angle as well.

I am afraid to push the RAM with a lot of force because I might ruin it.

Here is a photo of my RAM slots with one RAM installed.

EDIT Here is a photo with the RAM place in the socket. I can not push the RAM more "inside".

  • Please edit your question to add the exact model of Toshiba laptop you are attempting. Also, we see a picture of the slot but no picture of the RAM that supposedly won’t fit in the slot. So a picture of the RAM and maybe the exact model number of that RAM would help as well. – JakeGould Jul 23 '16 at 19:33
  • The Laptop is Toshiba Satellite C855x I am not sure about the model of the RAM(it is a Kingstone DDR3) but it fits in the slot 1 (and the computer is working without a problem), but it does not fit in the slot 2. – John.Doe Jul 23 '16 at 19:36
  • So since it fits in the slot 1 and works without a problem the RAM should be correct. – John.Doe Jul 23 '16 at 19:36
  • First, like I say in my comment you should edit your question to add details like the make and model of the laptop. These comments are not the place for stuff like that. And if the RAM fits in the other slot, this is all about carefully forcing the RAM into the slot. Try pushing the connectors in a bit more and then pushing the whole thing down to click it into place. – JakeGould Jul 23 '16 at 19:39
  • Add photo with not fitting, but placed in socket module. – Mikhail Moskalev Jul 23 '16 at 23:21

As in used SO-DIMM socket, module slide in place (in up direction on photo) almost itself by own weight.

For new socket, some reasonable insertion force must be applied (about 4 kg) in up (related to photo direction) in 30 degree until it fit in socket and then easy push it down to click.

As example, look how deep inserted module fits in socket.

Don't push it down with force to make it parallel to board and click before it go up in socket!

Sometimes necessary manually open latches to click module in place.

    I pushed with much more force and it went inside, thanks a lot for your help! – John.Doe Jul 24 '16 at 12:37

Normally ram in laptops is slotted in, at around a 35-45 degree angle, and then it'll 'click' down into place - on the second slot this angle can change hugely too - so just try wiggling the ram in place gently to see if you can see a way it'll fit and then click down into place.

  • Tried it but I cannot make it fit. I uploaded a new photo that better shows the problem I have. Please take a look at it. – John.Doe Jul 24 '16 at 11:41
