Understand the Basics of Memory in 3 Minutes
|
|
|
| Building a computer can be a very rewarding—sometimes frustrating—experience, since there are so many specifications to figure out. Take memory for example, can you tell the difference between DDR3 and DDR2? What do numbers 1066, 1333 and 1600 mean? Will upgrading to higher level memory necessarily result in higher computer performance? Now, let Dr.T help you find answers to these frequently asked questions. |
What is DDR?
DDR stands for "Double Data Rate," an advanced computer memory that can transfer data twice as fast as regular SDRAM chips. In today’s PC world, DDR3 shows the potential to replace DDR2 as the mainstream memory. It is because DDR3 memory delivers much lower operating voltage yet higher frequency compared to its predecessors—DDR and DDR2, and makes the memory much more suitable for the ever demanding requirements of today’s advanced computers. |
◎ What is Memory Clock?
Memory clock means the clock speed of the memory. It is measured as a frequency in hertz, and a megahertz refers to one-million cycles per second. For instance, if your memory clock is 1333MHz, it runs 1333,000,000 cycles per second. The higher the clock speed, the faster the data transfer. |
| Additionally, those specially selected and engineered memory modules, such as DDR3-1600 and DDR3-2000, are called overclocking memory. They feature higher clocks and voltage, providing overclockers and enthusiasts with the best overclocking potential for their high-end computer systems. |
◎ Better Coordination, Better Performance
It`s important to remember that all of the system components must be supported by the motherboard itself. If you were to upgrade your memory, you can`t just search online and buy whatever falls into your price range. To help your computer run as quickly and efficiently as possible, you must make sure the type of memory you buy, and the size is supported by your motherboard. |
