Everything about DDR

Many people know only what they want to build a new system or upgrade an existing system. To enter into perfect harmony with the CPU, motherboard and graphics card combination of their choice, but when it comes to memory, simply have no idea, much less what is DDR. If you are one of those people, then here is all about the DDR, you need to know.

Because DDR memory?

DDR (Double Data Rate) memory technology is an evolutionarybased on SDRAM. The DDR SDRAM is accessed twice as fast as SDRAM, as for the transmission of data at both edges of the clock. It's quick, to transfer data at up to 2133MB / s. It also consumes less energy than conventional SDRAM or other memory types, with an operating Vcc instead of just 2.5Vcc 3.3VDC SDRAM.

Which DDR buy?

Depending on your needs and your system, you can trade in one of DDR memory (DDRII, DDR2 or DDR3). The selection ofLegal DDR variant is a very important factor in determining overall system performance.

DDR1 Memory

DDR1 is available as a registered or unbuffered. DDR1 has buffered its address and control lines to reduce the load signal, and is more expensive than DDR1 Unbuffered. DDR1 Unbuffered feature not address the line of control buffer, so that costs less. be installed in opposition to the registration DDR1, DDR1 may only unbuffered on a motherboard to a maximum of 4 *1GB.

DDR2

This is the second generation of DDR memory. While the 400MHz is the highest speed for DDR1, is the lowest for DDR2. This means that DDR2 pick where DDR1 leaves off. Because of different latencies, we can surpass DDR1 400MHz DDR2 400MHz, DDR2 but the advantage back to the vehicle speed when you reach the next level (532MHz), can not reach the DDR1.

DDR3

This is the third generation of DDR memory. It starts with a speedLevel of 800Mbps (400MHz) to the lowest available. Today, the highest speed DDR3 is popularly available to two billion data transfers per second.

DDR memory, compatibility

It is not advisable to just go into a shop and buy any DDR available to the system. You must consider the compatibility of DDR memory. You can find the switch compatible DDR, DDR2 or DDR3 memory upgrades or all of the system to the new scanner system for the appropriate DDR-ScanMemory.

What is the selection of DDR memory

In addition to compatibility, you must check the different latencies on the market to compare different brands and prices and other factors which are preferred shares to you.
