RAM frequency has been updated most of the time and we are not able to judge what we need to buy. Here is a list of RAM upgrades and specifications. Plan before you buy one of them.<a href="http://sundararajan.files.wordpress.com/2008/10/ddr3.jpg" target="_blank"><img src="http://sundararajan.files.wordpress.com/2008/10/ddr3.jpg?w=337&h=78" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>DDR1 is the first of the Series of the DDR-SDRAM and comes in the following series. The technology and its stable operation led to the invention of the latter memory modules. This powered the Entry level Pentium 4 series of boards and was a breakthrough from the older SDRAM.DDR SDRAM: Double Data Rate SDRAM (DDR200, DDR266, DDR333 are standard)PC1600 (DDR-200 SDRAM); Clock Speed: 100MHz, Data Rate: 200MHz, Throughput 1600MB/sPC2100 (DDR-266 SDRAM); Clock Speed: 133MHz, Data Rate: 266MHz, Throughput 2100MB/sPC2400 (DDR-300 SDRAM); Clock Speed: 150MHz, Data Rate: 300MHz, Throughput 2400MB/sPC2700 (DDR-333 SDRAM); Clock Speed: 166MHz, Data Rate: 333MHz, Throughput 2600MB/sPC3000 (DDR-366 SDRAM); Clock Speed: 183MHz, Data Rate: 366MHz, Throughput 2900MB/sPC3200 (DDR-400 SDRAM); Clock Speed: 200MHz, Data Rate: 400MHz, Throughput 3200MB/s    DDR2 Memory is Second series of memory developed from the DDR1. The speeds and built technology of these memory modules is much superior to the DDR1. This memory was also launched in a low and affordable cost which led to a great increase in memory sales. The high speed version of this memory boosts performance of gaming and animation related task.DDR2 SDRAM: Double Data Rate SDRAM II (Quad Edge Clock Rate, 1.8v signaling), Second GenerationPC2-3200 (DDR2-400 SDRAM); Clock Speed: 100MHz, Data Rate: 400MHz, Throughput 3200MB/sPC2-4300 (DDR2-533 SDRAM); Clock Speed: 133MHz, Data Rate: 532MHz, Throughput 4300MB/sPC2-5300 (DDR2-667 SDRAM); Clock Speed: 167MHz, Data Rate: 667MHz, Throughput 5300MB/sPC2-5400 (DDR2-675 SDRAM); Clock Speed: 167MHz, Data Rate: 667MHz, Throughput 5400MB/sPC2-6400 (DDR2-800 SDRAM); Clock Speed: 200MHz, Data Rate: 800MHz, Throughput 6400MB/s  DDR3 Memory is the Third generation of DDR memory. It has been launched and is priced low to suit most of the PC consumers. This memory is expected to power the entry level servers, Gaming PCs and High-end Graphics related tasks. Sure this will make ours a high-end desktop PC.DDR3 SDRAM: Double Data Rate SDRAM III (Quad Edge Clock Rate, 1.5v signaling), Third GenerationPC3-6400 (DDR3-800 SDRAM); Clock Speed: 100MHz, Data Rate: 800MHz, Throughput 6.40GB/sPC3-8500 (DDR3-1066 SDRAM); Clock Speed: 133MHz, Data Rate: 1066MHz, Throughput 8.53GB/sPC3-10600 (DDR3-1333 SDRAM); Clock Speed: 166MHz, Data Rate: 1333MHz, Throughput 10.67GB/sPC3-12800 (DDR3-1600 SDRAM); Clock Speed: 200MHz, Data Rate: 1600MHz, Throughput 12.80GB/s</blockquote>
