Laptop ram is the memory that your laptop uses to function. There are different types of ram: DDR2 DDR3 and DDR4. These two types of ram have a lot in common, but there are small differences between them as well. DDR3 is still being produced but it will begin to diminish over time because it does not have what it takes to keep up with the newer technology around us today. The main difference between these two types of ram is speed which can be measured by Mhz or MHz (megahertz). The higher this measurement goes the faster the computer will run and process information at a much more efficient rate than if you had lower speeds on your machine. If you’re in need for some new laptop RAM then I highly recommend looking
DDR4
I mentioned earlier, DDR4 may be a little more expensive than DDR3 but it will be worth it in the long run. The prices on this type of RAM have decreased substantially over the past couple years which is why many people are now choosing to purchase new computers that include DDR4 ram instead of DDR3. Laptop ram comes typically comes in pairs of 2 sticks, so you’ll need to replace both sticks if your computer memory has become too low or broken. Make sure that when you are purchasing your laptop ram that you always get compatibility information from whomever or wherever you are buying them from so there are no mistakes made with what parts actually go where.

DDR 2 DDR 3 DIFFERENCE
DDR2 was one of the first types of laptop ram to come out. It has now been phased out because it is not compatible with most laptops today.
• Bus Width : 64-bit bus width
o 66 MHz o PC1600 & PC2100 have a transfer rate of 1,066 Mbps o PC2700 & PC3200 have a transfer rate of 2,133 Mbps
• Bus speed : 266MHz o 400MHz for dual channel mode
• Transfer Rate : 800Mbps o 1250Mbps in burst mode BUS SPEED BUS WIDTH TRANSFER RATE – The number of bits that are processed per second by the computer’s memory controller . Also referred to as data “rate” or “speed.” As of 2011, PC1600 and PC2100 and PC2700 and PC3200 were the most common RAM speeds. – The bus transfer rate is also referred to as the effective memory clock speed . – A set of parameters that define how fast data can be transmitted between computer components, such as CPU and memory modules .
DDR3
DDR3 offers many advances over its predecessor DDR2. Some of these improvements include more bandwidth for high-end computing applications like gaming and streaming HD Video , lower voltage requirements (1.5V compared to 1.8V), improved performance at higher frequencies (up to 1600 MHz), optimizations for low power operation , enhanced signal integrity and other refinements that translate into superior overall system performance with less power consumption DDR3 memory modules.
DDR2 vs DDR3 RAM comparison
Speed, size and compatibility are major factors in deciding which type of laptop ram to use when upgrading a computer. Here we will go over the differences between these two types and provide you with some information on how to tell them apart so there aren’t any mistakes made in buying incompatible parts. The main difference between these two types is speed. They can both be measured by Mhz or MHz (megahertz). The higher this measurement goes the faster the computer will run and process information at a much more efficient rate than if you had lower speeds on your machine. When it comes to compatibility; almost all laptops that were manufactured after 2006 use3 DDR3 ram.
Most likely use DDR3. If you’re looking to upgrade the RAM on an older laptop (or desktop for that matter) then you should look into DDR2 RAM instead. However, don’t make the mistake of purchasing a higher speed than your system can accommodate! This WILL cause problems and I highly recommend against it. When purchasing laptop ram you should always check what type of motherboard and processor is already installed on your machine before making any purchases. It does not make sense to do otherwise because replacing parts with ones that are incompatible could cost you time and money to get everything running smoothly again .
Always verify that the size of the memory modules you are purchasing match those that are already installed on your machine. Here is a standard list of the sizes and dimensions for desktop ram: DIMM Sizes Length (in inches) Width (in inches) Chip organization Chip capacity 8.5 1 2 171 pins 512MB 10 1.27 2 184 pins 1GB 12 1.2 2 240 pins 2GB 13 1.44 4 240 pins 128MB 16 1.6 4 240 or 244 pins 256MB 18 1.8 4 278 or 288 pins 512MB 20 2 4 312 or 314* pins 1024MB 22 2 4 400** pins 2GB 24*** 3*** 420*** bytes 8192 MB * Pin holes range from 248 to 371 ** Pin holes range from 977 to 1085
