So-dimm 4GB SDRAM DDR3 de Ordenador

Switch Tabs and Windows with Ease Using SO-DIMM 4 GB DDR3 SDRAM

As the speed and power of communications technology grow, so must the capabilities of your laptop computer. Websites will only continue to require more memory of your system that keeping up will require a decent upgrade. Luckily, SO-DIMM 4 GB DDR3 memory with decent MHz frequency rates is easy to come by and install.

What Is SO-DIMM or SODIMM DDR3 SDRAM?

• SO-DIMM: This term stands for small outline dual in-line RAM that uses integrated circuits to store set amounts of data at relatively faster speeds compared to traditional hard disk drives. These modules are designed in such a way that they lay flat on the motherboard in order to maintain a slim form factor that is necessary for modern thin and light laptops and all-in-one computers. Depending on the manufacturer, you can find 4 GB, 8 GB, and 16 GB options for these DDR3 with various data rates described in MHz.
• DDR3: This acronym stands for double data rate 3, which refers to a type of RAM standard that uses a high bandwidth interface, which allows the DDR3 SODIMMs to perform two operations in one cycle. These modules have a 204-pin configuration as opposed to 240-pin on regular DIMMs and have a key along the contacts at the bottom of the module to prevent slotting into incompatible laptop memory banks. This is key because DDR3 SDRAM is not backward nor forward compatible due to different signaling voltages wherein the stock voltage of DDR3 is 1.5 volts and other standards use higher voltages. When you see something like "DDR3-1066," the number indicates that the module puts out 1066 MHz using the DDR3 standard.
• SDRAM: This means "synchronous dynamic random-access memory," which is a type of memory where an externally supplied clock signal coordinates the operation of its external pin interface. SODIMM versions of these non-ECC memory modules are widely used in laptops and notebooks for their speed and comparable frequency output (in MHz) to desktop counterparts. 

What Is 4 GB of SODIMM RAM Good For?

• Budget Builds: SODIMM DDR3 sticks can benefit a laptop that has seen its days of use but can still pump out a few more years. Many laptops have dual-channel motherboards which allow for two memory modules to be inserted into the 204-pin laptop memory banks, so you can have two 4 GB modules or two 8 GB modules depending on the amount of RAM your laptop can handle at max. 
• 32-bit Systems: Laptop and computer operating systems can limit the amount of usable RAM it can accept. For 32-bit systems, it only uses 4 GB of memory, so it is pointless to add more unless you want to reinstall a 64-bit version of the OS to get more use out of a large RAM module.
