If you ever wondered whatRAM, how it works, what function it performs in the computer, how to clean the RAM, how to set the RAM bar, what types there are, then you will find answers to your questions in this article.
What is RAM?
Оперативная память (ОЗУ – оперативно-запоминающее device) is an integral volatile part of the computer in which the executable machine code is stored during system operation. As well as input and output data processed by the processor.
At the present time, we are accustomed to seeing operationalmemory like a small green bar with microchips. But she did not always look that way. Initially, these were vacuum tubes. But then the Bell Labs lab opened a new era - transistors. It is they who in all modern types of memory have become the main component. In further development, the memory was improved by combining the transistor and capacitor, which allowed it to become smaller and more dynamic.
Dynamic and static memory
RAM is divided into two types: static and dynamic.
Статическая память – это схемы, которые use a parallel registry as a storage cell. The memory stores temporary information and uses two operations: writing and reading. The advantage of static memory is its high speed. Among the shortcomings, it is possible to emphasize only the high price compared to the dynamic memory and the large size of each memory cell.
Dynamic memory combines the transistor andcapacitor so that the cells have a minimum size. The speed of this memory can not be compared with the speed of static memory, but it is compact in size, which gives it an advantage in places where compactness is required, and not speed. Modern element base will allow to accommodate millions of pairs per square millimeter of memory chips. The main disadvantage of it is the need to regenerate the charge of the capacitor due to its fast self-discharge.
DDR generation
Also, RAM is divided by type Double Data Rate (DDR). There are 5 generations of this type of memory: DDR, DDR2, DDR3, DDR4, DDR5.
Consider three types.DDR is the oldest kind of memory. To date, it is difficult to meet in the computer, but you can still buy. In order to install memory, you will need to find an outdated type of processor and motherboard that use this memory. DDR requires the most electricity compared to other DDRs. Operating voltage - 2.5 volts, if the processor is overclocked, it requires more.
DDR2 is the next version of memory.It is more common, and to meet her in the computer a chance is higher than DDR. DDR2 is faster than DDR. Consumes 1.8 volts. When you overclock the processor, you will need more - just like DDR without overclocking.
DDR3 is not the newest, but not the old type of memory.At the present time, the most common type. It works several times faster than DDR and DDR2. Electricity consumes even less. It takes 1.5 volts for the memory to work and a bit more for overclocking the processor.
The following versions of memory evolved at the same pace. But DDR3 is still the most common.
How to install and how to clear the computer's RAM?
Before buying RAM, you need to make sure thatThat on your motherboard slots fit the type of memory you want to buy. For example, if the memory type is DDR3, then the slots on the motherboard should also be DDR3. If you buy RAM, which is not suitable for your motherboard, then the module simply will not enter the slot.
How to install the module in the computer? It is necessary to do the following:
- Turn off the bolts and remove the computer cover.
- Next, on the memory connector, turn the jumpers.
- Make sure that the memory fits the slot. To verify this, it suffices to see if the cut-out on the memory fits under the tab in the connector.
- We insert the module into the slot and press down with two fingers on the memory until the jumpers themselves click and close.
- Next, check whether the memory is holding tight. If the memory does not move in the slot, then you did everything right.
- We twist the cover of the case.
- Turn on the computer and go to the "System Properties". If opposite the line “Installed RAM” indicates the parameters of the installed memory in the computer, then the modules have been successfully installed.
Now consider how to clean the memory of a Windows computer. To accomplish this task, there are several ways. Let's sort the simplest.
How to clear the RAM of Windows 7? The first method of cleaning is manually:
1. Open the "Task Manager".
2. Go to the tab "Processes".
3. Close the suspicious, unnecessary processes that use the most memory.
The second way:
- In the line "Open" type msconfig. Click “Ok”.
- Go to the "Startup" tab.
- On unnecessary programs, remove the check mark and click "Apply".
You have disabled programs that start immediately, with the computer turned on.
Conclusion
In this article, you learned how to clean the RAM, how to choose the right module for your connector. Now this question will not cause difficulties for the reader.
