Upgrading memory with best RAM

With new technologies, novel techniques are cropping up which is giving rise to smaller, faster and better PC’s. The requirement of feature rich web, bigger and better applications and faster & intense games, the two things one looks for in any PC is speed and its performance. We all know that RAM is one important unit in a computer which helps the computer in its functioning & performance. The question that arises is which RAM is considered to be the best for your computer?

Once you take a decision of upgrading your computer, the two things you necessitate to know is, what type of RAM – SDR, DDR, DDR2 or DDR3 is already installed in your computer and secondly, how much bandwidth can your computer’s motherboard can accept. Different types of RAM which are available are :

SDRAM : This is an old generation RAM and has become obsolete today as we have much faster, better and more efficient ways of storing memory.

DDR2 RAM – This RAM is faster than DDR and is more commonly used today, specially in desktops PC’s. It is physically different from DDR1 memory RAM and cannot be used on computers that do not come with DDR2 technology. It has 240pin sets. The lowest level speed in DDR2 RAM type is 400Mhz and goes up to 800Mhz. DDR2 RAM can function at a faster speeds and also adjust greater data bandwidths, which helps in browsing the internet much faster. This RAM not only consumes less power but with enhanced thermal performance keeps the computer cool for a longer period. People who are still using old computers at home and offices, still prefer DDR2 RAM for up gradation.

DDR3 RAM - This RAM is considered to be new generation RAM and is used for super fast processing by users. Since, DDR3 is the latest version of RAM in the market today, it has boomed the market that works with ‘Triple Data Rate’ system. DDR3 is much faster in speed and performance due to the doubling of the data bus speed and also takes less amount of power supply. The technique used in DDR3 RAM for low power consumption is so neatly grouped with the memory module that it uses less power compared to the power used in DDR2 RAM. Most of today’s laptops & desktops are being manufactured with DDR3 technology. Today, various sizes of computer RAMs are available in the market which are ranging from 512MB to 16GB modules.

In this prosperous marketplace of memory today, it is difficult to stay away from cheap deals and imitations. We require to be aware of dealers who are providing outstanding deals on duplicate products to attract customers. These products may contain defective pieces which on use can spoil your computer and you end up dropping more money on its reparation. It is constantly advisable to stick to branded shops which are keeping branded memory modules and have a good after sale services.

One such manufacturer, exporter and trader of branded memory RAM is Om Nanotech Pvt Ltd, who is not only selling quality products but also passing on full after sale support.

DDR2 More Efficient Than The Original DDR

DDR2 is a type of an SDRAM, this computer memory stores its memory in memory cells. These cells are then activated at according times to correctly operate with an external data bus. Although the DDR2 shares many similarities with the original DDR, as in the case with data transfer happening with the rise and fall at the edge of the clock, it is different in that the DDR2's bus is clocked at twice the speed. This basically allows the DDR2 to be twice as more efficient than the original DDR.

The key behind the high bus frequency with DDR2s is the coalition of electrical interface improvements, prefetch buffers, and various off-chip drivers. This is because DDR's prefetch buffer is twice of the DDR, which is 2bits deep. Also, its read latencies are between four and six cycles; again this is twice that of the DDR. Thus, twice as much bus speed is necessary to achieve an equal latency.

Also, the DDR2 is packaged relatively more expensively and more complicatedly than the DDR SDRAM or the SDR SDRAM, in exchange for a more blazing speed.

Backward compatibility with DDR2 DIMMs are quite limited. In fact, they are not designed to be compatible with DDRM DIMMs at all. This is because firstly, the notch positions in the DDR2 and the DDR are different along with the pin density slightly higher on the DDR DIMMs. Although not much of a "backward compatibility," but faster DDR2 DIMMs can be used with slower DDR2 DIMMs. However, in such a situation, the faster one would run at the speed of the slower DDR2.
