Laptop Memory

There are lots of people who always in a conscientious effort to upgrade memory in laptop to increase its effectiveness. In desktop systems, you are normally given three or four slots for memory modules but this scenario is not seen with laptops as they only come with two slots.

Normally, laptops don’t use SIMM and DIMM memory which is used in case of non portable machines. When you will delve more into the details, you will find that following are the basic types of memory used in laptops;

• 72 pin SODimm

• 144 Pin SODimm

• SDRAM

• DDR SDRAM

Certainly the more memory in a laptop PC the better but there are other concerns regarding memory in laptops. Laptops are generally more restricted when it comes to terms of memory that can be installed into a system. More often access to that memory can also be a headache if you plan a future upgrade.

Most of the laptops are now using the DDR2 memory technology, but a number of new laptops use the DDR3 standard.

We generally find two ways through which the memory speeds can be designated. The first one is by the memory type and by finding its clock rating, like DDR2 400. Another r method is by documenting the type along with the bandwidth. In this instance the same DDR2 memory would be listed as PC2-3200 memory. Below is a listing in order of lowest to fastest memory types in both formats:

• DDR2 400 / PC2-3200

• DDR2 533 / PC2-4200

• DDR2 667 / PC2-5300 or PC2-5400

• DDR2 800 / PC2-6400

• DDR3 800 / PC3-6400

• DDR3 1066 / PC3-8500

• DDR3 1333 / PC3-10600

• DDR3 1600 / PC3-12800

In addition to the type of memory installed in the laptop, the speed of the memory can also make a difference in the performance. When it comes in terms of comparision, it is of outmost importance to check both of these pieces of information to evaluate how they may impact performance.
