The speed of the computer largely depends on the type and amount of RAM, so the easiest and most affordable upgrade is to add a memory module if there are free slots on the motherboard. For correct operation of the computer, it is better to use modules with the same characteristics. There are several ways to determine the type of installed memory.
Instructions
Step 1
There are many programs that determine the configuration of the computer and the types of components. Many of them are distributed free of charge. Download SiSoft Sandra and install it on your computer. Run the program. In the Information Modules section, find the Summary Information icon and click on it. After a while, an information window will appear, which contains information, including the installed memory. Please note that only older versions of SiSoft Sandra are available for free download.
Step 2
The CPU-Z program, which allows you to determine the configuration of your computer, is distributed free of charge. After installation, the configuration is analyzed. The result is displayed as a window. Go to the Memory tab to find out the type and characteristics of the memory installed on your computer.
Step 3
If for some reason you cannot use the first two methods, disconnect the computer from the electrical outlet. Unscrew the tightening screws and remove the side panel. Find the memory module slot on the motherboard - this is the smallest external card. Pull down the plastic latches that secure the module in the slot and remove it.
Currently, computers use three types of RAM: DDR SDRAM, DDR2 SDRAM, DD3 SDRAM. SDRAM memory is a thing of the past and a suitable bar, most likely, you have to buy hand-held. Find the manufacturer's name and type of memory on the module.
Step 4
If the memory type is not indicated in any way, try to determine it yourself. Modules differ in the number of contacts:
- SDRAM - 168;
- DDR - 186;
- DDR2 - 240;
- DDR3 - 240.
And by the location of the keys (slots on the contact pad). This is because DDR, DDR2, and DDR3 are not compatible. A DDR memory module, if it could be inserted into the DDR2 slot, would not work and vice versa. There are 2 slots on the SDRAM bar.
