Best DDR2 main memory

Random access memory (RAM) plays an important role and is the short-term memory of a computer. The more RAM there is in a PC, the faster it can work. If too little RAM is available, the operating system must store data and program parts on the hard disk (long-term memory). The hard disk is considerably slower than the RAM and this slows down the PC. Therefore, the user should upgrade the RAM from time to time.

Computer, Notebooks & Tablets: DDR2 main memory Video Guide

Fortunately, buyers no longer have to worry about the design (DDR2). The main memory is still offered in the trade in the designs DDR1, SDRAM, DDR3 and DDR4. Thus, the design does not play a role in the purchase. For this, buyers have to pay attention to other things and these have an effect on the price and performance of the RAM. As with other products, the DDR2 memory plays an important role. RAM from lesser known manufacturers are available at cheaper prices than the branded products. DDR2 memory from well-known manufacturers such as Corsair, cost by their name more money, hardly bring further advantages. Both the warranty and the performance are almost identical. In addition to the price, the performance of the RAM plays an important role. The different RAM modules can be divided into 3 categories: RAM for beginners, RAM for mid-range PCs and RAM for high-end PCs. For a normal computer that mainly works Office programs, the inexpensive entry-level memory bars are sufficient. These have a clock rate of 800 MHz and are offered in the trade under the designation DDR2-800 PC2-6400U. DDR2 memory for mid-range PCs is faster and has clock rates of 1,000 or 1,066 MHz. Therefore the RAM costs also more money than the models for beginners. The mid-range RAM is sold under the designation DDR2-1066 PC2-8500U. Users who have a powerful computer for current games will definitely need high quality memory. This RAM costs significantly more money than the other two memory locks, is much faster. The clock frequency is between 1,100 and 1,200 MHz and the DDR2 memory can also be overclocked. The RAM is sold under the designation DDR2-1200 PC2-9600U.

When buying, computer owners should pay attention to many things. First, they should open the computer case. The available RAM is directly on the motherboard and should be checked out. How much memory is available and how are the slots on the motherboard used? Based on this information, the user knows exactly what kind of DDR2 memory to buy. If, for example, 2 gigabytes of RAM are available, it can be upgraded to 4 GB with a 2 GB latch. If it is an old memory bar with a low clock frequency, then it makes more sense to replace it completely and buy a fast 4 GB RAM bar. Should the DDR2 memory come from a well-known manufacturer and can therefore cost more money or is a no-name product sufficient instead? How fast should the new RAM be? It makes little sense if the existing RAM is upgraded and the new RAM does not match the built-in memory. For example, if the existing RAM has a clock frequency of 1,000 MHz, then the new DDR memory should be just as fast. If it is an office PC, the inexpensive 800 MHz RAM is sufficient. For a powerful PC, a DDR2 memory with 1,000 MHz or more should be purchased.
