What Are Some Memory Types?

As you shop for memory, you will likely see that there are a few types available and thus wonder what the difference is between these types of RAM.

• One type of memory is called SDRAM. This stands for "synchronous dynamic random access memory," which means that the pin interface of the RAM works in conjunction with the external clock signal. It's a common type of RAM that's been used since the 1990s.
• DDR3 RAM features added bandwidth from previous types of memory, and the bus speed is increased as well.
• You can also check into RDRAM, which a type of memory module that stands for "Rambus DRAM." It's a type of SDRAM that is used for high-bandwidth operations, making it an efficient upgrade for your laptop.

Which Form Factors Are Available?

When you are selecting compatible computer memory, you also need to consider the form factor, and here are some specific types to choose amongst.

• DIMM (dual in-line memory module) denotes the number of chips on the board that connect the piece to your model's motherboard.
• Another form factor to select from is SO-DIMM, which is an acronym for "small outline dual in-line memory module" and offers a smaller design than DIMM does.
• ECC and non-ECC are two other terms you'll see when purchasing memory. What do these mean? ECC stands for "error correction code," and this type offers extra security at a high level that's not necessary for everyday use, which non-ECC works just fine for.

How Do You Choose Dell RAM?

You'll want to keep a few considerations in mind as you select RAM for your laptop or other computer models, and there are a few things to factor into the decision-making process.

• You'll need to know how many modules you need.
• The number of pins, such as 144, is crucial to know because this helps to ensure that the module fits into your motherboard the way it's supposed to.
• Verify that the module fits your computer series and your specific model, as matching the memory with the machine ensures a custom fit. Options to consider from this brand include the Inspiron series, the Precision line of devices, and the Latitude line of laptops.
