DDR or double data rate memory is said to be a memory technology (evolutionary) based upon SDRAM. The access to DDR SDRAM is twice the amount fast when compared with the SDRAM. This is because transfer of data is done over two clock edges. The transferring data is very quick. The consumption power is also lower when compared to the conventional type SDRAMs or any other memory types. DDR memory 1GB is now becoming the smallest memory capacity module deployed inside the computer systems as now many require computer systems with high capacity RAM memory. This is because the applications are big and the next reason is for enhancing the system’s performance.
DDR memory 1GB can be got based on the system type and preference of the user. DDR memory can be normally got as DDR1, DDR2, or DDR3. The right choice of DDR variant determines the whole performance of the computer system. DDR1 memory 1 GB can be got in the unbuffered or registered form. Its buffered control lines and address are meant to lower the signal loading that they are found to be costlier than the unbuffered DDR1 memory 1 GB. Unbuffered DDR1 memory are not the like the registered types that they could be installed only on a single mother board and to a maximum of four 1 GB memories. DDR2 memory is the second generation memory with a lowest speed range of 400MHz which actually happens to be the highest speed range of DDR1 memory. This would the idea of the speed of DDR2 memories. The DDR3 memory starts with the speed of 400 MHz. The DDR3 memories found today run at a speed of nearly two billion data transfers in one second.
DDR memory 1 GB memory need to be got based on the compatibility of the computer system. Memory selector can be used for finding out the compatible memory upgrades or you can even use the new scanner system to find out the compatibility of DDR memory 1GB with the computer. Identification of chips using part number is now possible. The modules every chip size need to be identified and then have to be multiplied with the chip numbers on the module with the size for determining the memory capacity. Various RAM manufacturers have come up with various identification methods that it is now hard for identifying the chips without having a look at the actual part number given on their websites.
