RESEARCH - 2022 163 Another important information. If you connect 2 RAMs running at different frequencies to one board, the total operating frequency will be related to the lower frequency. For example, you connect 1000 MGS and 600 MGS of RAM on the same board, so that the RAM runs at 600 MGS. Below is a screenshot where you can see the main features of DDR memory modules. However, it should be understood that these values relate to only one module row. But still, of course, now the chipsets installed in the computer support the dual-channel mode of operation of DDR RAM. How to get the maximum performance of your computer BEST SCIENTIFIC RESEARCH - 2022 164 The highest performance of the computer can be achieved only when the bandwidth of the processor and RAM are compatible. Therefore, in order to achieve the highest performance of the computer, you need to understand which RAM memory is suitable in the optimal configuration for a particular processor model. For example, we have a Pentium 4 processor with a bus frequency of 800 MHz. This example is more relevant to the mid-2000s, but in principle it can also be applied to modern computer models. For one cycle, this processor transfers 8 bytes of data. But its operating frequency is 800 MHz. So we multiply 800 MHz by 8 and get the number 6400 Mb/s. So we dealt with the processor. Now select Ram. Since DDR memory works in dual channel mode, we need two PC3200 memory modules. The data transfer rate of one module is 3200 Mb/s, and two modules multiply 3200 by 2, equal to 6400 Mb/s. In this case, fully synchronous data exchange is carried out between the processor and RAM, which prevents delays in the operation of the computer. Thus, we considered the main features of DDR RAM and its main differences from SDRAM memory. They learned to choose the right RAM and processor of the computer for optimal system performance. In the next article, we will look at DDR2, which is another link in the evolution of computer RAM development. REFERENCES: 1. W. Stallings Data and computer communications. Pearson Education, Inc.
