DDR2 or DDR3 for Toshiba Satellite laptop C655-5082



Dear Bob,

Each DDR has its own specifications and modules, and the every module cannot be used on the same pattern as there is the difference of speed and processing of each RAM modules. First thing, if the Laptop has the slot of DDR3 only than it is not possible that you can insert a DDR2 RAM in the slot. ALL DDR3 modules cannot be used in your laptop. The reasons are:

  • Different processing power even within DDR3 of different kinds.
  • Compatibility Problems.
  • Speed.

So I would prefer to take your laptop with you to the authorized dealer and then they will check and know which DDR3 would be compatible with your Toshiba laptop. Hope this will help. Thanks.

If you want to upgrade the physical RAM of your Toshiba Satellite C655-S5082 laptop, you need first to verify what version of Microsoft Windows is running to check if you are using 32-bit Microsoft Windows. This is because 32-bit operating systems have memory restrictions when upgrading the physical RAM.

If you are using a 32-bit operating system, the total amount of RAM that can be utilized efficiently is only around 3.25 GB. So, if you have around 4 GB RAM, 0.75 GB more or less will be wasted. If you want to upgrade the physical RAM to more than 2 GB, you must upgrade your operating system to 64-bit because it can support up to 17 billion GB.

Upgrading to 64-bit Microsoft Windows is hardware dependent. This means, both your motherboard and processor should support 64-bit. 64-bit motherboard can support 32-bit processor but it will not work at full speed. If you have 32-bit processor, you can only install 32-bit OS. But if you have 64-bit processor, you can install either 32-bit or 64-bit Microsoft Windows.

For your Toshiba Satellite C655-S5082 laptop, the maximum supported memory is 4 GB and it also supports DDR3 memory modules.
