What Does 512Mb DDR Memory Mean?
Memory can make or break how fast a computer system runs programs and applications. Upgrading memory can often be the most inexpensive and simple road to better computer performance. It is widely held that computers function at an optimum level with as much memory installed as the processor and motherboard can handle.
The Facts
512Mb DDR memory refers to the amount in megabytes of double data rate random access memory available in a computer. DDR memory is also known as DDR RAM. DDR RAM is a type of computer memory that transfers twice the data by utilizing the clock signal differently to deliver the data in a shorter interval of time. 512Mb of DDR RAM is considered an upgrade for use with high-level graphics programs.
Function
DDR memory serves as a go-between in relation to accessing data from the hard drive. Data is transferred to the memory for an interval of time so that the hard drive does not have to be accessed with each call for data or an application. Accessing the hard drive repeatedly would slow down computer processing speeds to a crawl.
Features
DDR RAM comes in a dual in line memory module (DIMM) that is 184 pin. The module is distinguishable from others by having a single notch in the access point that is off-center.
Benefits
DDR memory has the purpose of boosting a computer's performance relative to data transfer. The faster the memory can accept and transfer data, the faster applications and processes can receive and use the data. This leads to better performance and the ability to multi task using more programs at once.
Considerations
The amount of memory on a computer system must match the amount of memory that can be handled by the motherboard and the processor. If this is not matched, adding extra memory will have no effect on processing speeds.
