DRAM modules and its significance

DRAM stands for dynamic random access memory. DRAM devices usually use capacitor charges on an integrated circuit to store the digital information. The capacitor must me recharged frequently, so that the information is retained. So, DRAM is a volatile memory.

DRAMs are generally manufactured in different formats. Some of them are DIP which is Dual in-line package and SIPP, SIMM, DIMM and many other formats. The RAM memory cards used in present day computers are a type of DRAM in DIMM format. DDR3, DDR2 , DDR and SDRAM are synchronous DRAM modules.

DRAM is made to be in sync with the clock of system bus. DRAM chips may contain information after the power supply is removed for longer time at lower temperatures. Under proper conditions, a DRAM is found to contain data for several minutes after power off. This data can be used to break in to encrypted systems and steal private information.

Is DDR3 faster than DDR2?

DDR2 and DDR3 are the memories of the motherboard. Is ddr3 faster than ddr2? The answer is yes but not all the time and it still has its disadvantages too. It’s faster and has more bandwidth and produces less heat but when dealing on the price of ddr3, it’s two to three times more expensive than ddr2 memory especially when choosing a 4GB kit. Ddr2 memory has very tight timings therefore, even at its lowest range of speed, it can still outperform ddr3 memory to its highest speed. Bandwidth and memory latency are the factors that affect the speed of performance by both memories.

DDR3 SDRAM and its advantages over previous versions

DDR in DDR3 stands for Double Data Rate. It is the latest memory standard for hispeed SDRAM that we use in our computers. DDR3 is a improved version of DDR2 in many aspects. DDR3 Ram is a type of DRAM. DDR3 shows a lesser power consumption of 30 percent and also a lower operating voltage when compared to DDR2.

Lesser power consumption means less amount of heat generated. So, the cooling needs of DDR3 are less than DDR2. DDR3 Ram is not forward or backward compitable with any type of other RAM as the operating voltages, clock speeds, timing and several other factors.

DDR3 memory has a high bandwidth interface. In addition to all these advantages, DDR3 memory type also provides the facility of having up to 8 Gigabites of memory on board. DDR3 RAM modules have different notch positions to DDR2 to prevent accidental insertion of DDR3 memory in to DDR2 slots.

Types of Computer Memories

We have come a long way from the days when heavy tape drives were used to store information to hand held little devices available today. Computer memory is nothing but the collection of data on physical devices in a digital format i:e 0's and 1's.

To classify memory, there are two types broadly, one is volatile and the other is non volatile. As their name suggests, volatile memory can store information only till it is supplied with electric energy and non volatile memory can retain the information even after the supply is disconnected.

In present day computers, RAM is a volatile but high speed memory, while Hard Drives are non volatile but low speed memory. There are many types of volatile and non volatile memories that have been developed. Among them, Different types of RAM like SDRAM, DDR, DDR2, DDR3 etc stand for volatile and flash drives, hard disks and optical storage devices are a few types that come under the non volatile category.

DDR3 Memory for Super Fast Data Transfer

Computers are one of the greatest inventions of all time. We cannot think of our daily lifes without the magic touch of a computer. A few years earlier, the technology used for the computer was not so updated. The device that acts as the primary memory of the computer is known as RAM or, in other words, random-access memory. Different types of memory modules are now available such as DDR1, DDR2, and DDR3. However, DDR3 is the latest addition in the realm of primary memory for computers. It stands for Double Data Rate 3. This means; it transfers data at a doubled rate than DDR2.

The DDR3 memory module enables the computer to perform faster for any kind of tasks like gaming, video editing, parallel copying, civil or architectural designing, and many more. So, if you want to feel the super speed of a rocket within your computer, get a DDR3 memory module and feel the difference instantly.

Want To Buy DDR3 SDRAM?

DDR3 SDRAM is the latest technology or model of RAM. It reduces heat and power consumption. Its clock speed is higher (faster) than that of DDR2 memory and other DDR memory products. Since DDR3 RAM runs at a higher clock speeds as mentioned previously this will make all components within the processor and graphics card run faster and benefit from receiving information at a faster rate. Therefore DDR3 RMA memory works more efficiently, giving a boost to frame rates while gaming. It also transfers data at twice the rate (eight times the speed of its internal memory arrays). It can enable higher bandwidth. DDR3 SDRAM gives a transfer rate of (memory clock rate) × 4 (for bus clock multiplier) × 2 (for data rate) × 64 (number of bits transferred) / 8 (number of bits/byte). Thus with a memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of 6400 MB/s. In addition, the DDR3 standard permits chip capacities of up to 8 gigabytes.

Should You Switch From From DDR2 to DDR3 Memory ?

Many motherboards support using both DDR2 and DDR3 memory, but the only problem is that the processor used can dictate which type of memory is acceptable to install. For example, using an Intel Core i7 or i5 processor means you're going to have to use DDR3 memory, no matter what your motherboard supports. On the other hand, some processors only support DDR2. So be sure to read your motherboards instructions carefully, otherwise you could end up wasting your money.

Now, with that being said, if you find yourself in the position of having to choose between both types of memory - and there are no technical hurdles in the way - then this becomes a question of price versus performance. DDR2 is very economical. Well, to put it bluntly, DDR2 memory is cheap. DDR3, in comparison, is pretty expensive. While you do get a slight performance advantage with DDR3, the real advantage is your ability to upgrade. DDR2 is old technology, and it's slowly being phased out (slowly being the key word here). In the future, almost every computer will use DDR3 memory, and upgrading from DDR2 is going to be a hassle. On the other hand, you can get a lot more memory by buying DDR2 now. In fact, you can get almost double the amount of RAM by buying DDR2 memory instead of DDR3. For those that recall the transition from DDR1 to DDR2, the move from DDR2 to DDR3 will be much the same. It will take years for DDR3 to become main stream.  Lastly, those with a DDR2 motherboard have nothing to worry about as DDR2 production will continue with even improved parts still on the drawing boards.
