Buying Guide For 1 GB Computer DDR2 SDRAM Memory Components

The memory in your computer like laptop memory is one of many components that make your computer work. There are different types of RAM available, including those starting at 1 GB in size, and these components insert into one of the memory slots on the motherboard. Selecting RAM can be one way of upgrading the performance of your PC.

What is RAM?

Random access memory (RAM) is used by your computer as a form of short-term memory. It requires power from the power supply unit. Once the computer is turned off, the data stored in the memory is lost. Some memory modules will have heatsinks mounted on the top of the card to aid in heat dispersion.

How do you select DDR2 SDRAM?

  • Gather computer information: You will want to know the processor type and motherboard type to select a compatible memory module for your system.
  • Select a bus speed: For DDR2, the bus clock ranges between 200 and 533.33 depending on the type of card. The bus clock will be measured in megahertz (MHz).
  • Choose a brand: You can select from a variety of branded and unbranded desktop and laptop memory cards. DDR2 is a standard type of memory card that fits a certain style of motherboard.
  • Select a form factor: This will determine the size of the module. Micro and mini motherboards and laptops will use one style while desktop computers will have the standard size.
  • Choose number of modules: Review the motherboard to determine how many channels are available. This information will help you determine how many cards are needed.

What is the difference between DIMM and SO-DIMM

DIMM is a type of card is used for desktop computers and servers. The dimensions of this card is 133mm. The number of pins on these cards range in the standard 168, 184, and 240 pin designs. SO-DIMM is a type of module used in laptop computers, with dimensions of 67mm in length. SO-DIMM comes with standard pins of 144 and 200 pins.

What is DDR2?

DDR2 stands for double data rate 2, which is the second generation of SDRAM. Different modules for these indicate the peak transfer rate of the particular card. The clock speed of these will range between 100 MHz to 266.67 MHz. The DIMM version will have 240 pins and a single notch while SO-DIMM styles will have 200 pins.

What are memory channels?

Some motherboards and processors are compatible with multichannel memory. Dual-channel motherboards will have color-coded sockets, so that you know which slots to insert the memory cards in. In multichannel formats, you want to select cards that have the same speed. Mismatched cards can have the system run the pair at the speed of the slowest card. There are also triple, quad, six, and eight-channel designs as well.
