Memory, also known as Random Access Memory , is an important part of computers and laptops. As you use your computer or laptop, the data is loaded into memory from the programs. This guarantees fast access to these data at all times. Without question, access time and speed play a very important role in data transmission. In the past, many computers were equipped with DDR SDRAM modules. Today DDR3 RAM and DDR4 RAM are standard, which are much faster than the older modules . Thus, an upgrade is also worthwhile – make the practice test with a product from our test or comparison table.
Purchase advice: How to find the right PC RAM in 2019
- DDR4 RAM modules have achieved the best clock rates. A higher clocking guarantees a better speed, even at full capacity.
- DDR4 memory has low power consumption. You can also reduce the energy consumption of your computer with a good cooling system.
- Since the market introduction of SD-RAM, a significant increase in performance of random access memories has been identified. High performance is especially important for games and work-heavy applications.
The RAM, also known as DDR-SDRAM, is a semiconductor product. It is currently available in four different versions: Older computers or notebooks with DDR-SDRAM modules work with around 184 contacts. New computers already include DDR3 RAM, which includes 240 contacts. These chips work at a speed of 8,500 megabytes and are much faster than their predecessors.
1. The properties of a working memory
By RAM definition RAM stands for Random Access Memory and represents a fast and freely usable memory in the computer. The data is stored on this memory for a short time and made available to the processor and the hard disk – hence the term “main memory”. Important: The data size of the main memory is specified in gigabytes.
Viewed from the outside, a memory looks like a flat bar that contains many contact points and is installed on the motherboard . Meanwhile, the new computers and hard drives use the DDR3 RAM or faster DDR4 RAM.
Attention: DDR3 and DDR4 memory are not compatible with each other . This also means that a motherboard has a socket only for DDR3 or DDR4 memory. This point should be considered before purchasing memory.
2. The tasks of the main memory
Memory is essential to the health of a computer – this can be clearly seen in tests for memory. If there is no RAM, the PC or notebook can not be started. Therefore, it is also important that the memory works well.
In most cases, two RAM bars are installed in the system, which is also referred to as dual-channel operation. But it can happen that only one bar stops working. So, if it should come to power drops, you will not always be able to determine this immediately. At least not if you do normal tasks on your computer. However, if you perform more demanding activities, such as gaming or video editing, you will notice the performance hit.
3. types of random access memories
RAM can be found according to RAM memory tests and RAM memory comparisons in different versions . Very widely used are various memory tests according to the DDR3 RAM and DDR4 RAM modules. It is expected that in the near future, the DDR5 memory come on the market. Below is a list describing all types of memory.
|DDR4 memory||This memory is the latest version. It is available in different memory sizes. The clock frequency is between 1,600 and 3,200 MHz.|
|DDR3 memory||8GB RAM DDR3 RAM has been integrated into PCs and laptops since 2007. A few years ago they were still considered the best memory. Meanwhile, the DDR4 modules are better. The clock frequency is between 800 and 2,000 MHz.|
|DDR 2 memory||This memory is often available in 1 GB, 2 GB, or 4 GB memory sizes. These memories are cheap, but the memory speed is low. Motherboards are no longer made for this memory.|
|DDR memory||This memory is cheap to buy. They reach clock frequencies of up to 400 MHz.|
|SDRAM memory||Very outdated and only small capacity. The offer in the market is therefore very small. The purchase is not recommended.|
3. Advantages and Disadvantages of Memory Types
The most common memory is DDR4 and DDR3. Here are the main advantages and disadvantages for all models at a glance:
|DDR4 memory||Is up to four times faster than DDR3 and has higher storage capacity||Not compatible with any processor|
|DDR 3 RAM||Is partially cheaper and available in quite high memory sizes||Is slower than the DDR4 memory|
|DDR 2 memory||Can often be bought very cheap||Often has only a small storage capacity and is too slow|
|DDR memory||Cheap to obtain||Slow, low storage capacity|
|SDRAM memory||Cheap in purchase||Storage capacity very low. Memory is very slow|
4. The largest manufacturers of random access memories
If you want to buy a memory, it may be useful to obtain it from a known manufacturer. This is what the results of some memory tests showed. Because: In general, the memory test winner and best memory come from well-known brands. Good quality has its price, because the original memory modules are very expensive, if for example they come from Samsung or Toshiba. You can therefore buy a so-called Third Party Module . These RAM memories often perform very well in the tests. They are equipped with memory chips from Samsung or other major manufacturers and are attached to their own modules. The following third party module brands are recommended:
- G. skill
- Kingston Technology
5. Purchasing advice for working memory
If you want to assemble a computer on its own, you definitely need a working memory. But even if your memory just should not work properly, it’s worth it if you buy an extra RAM memory .
Important to buy is that you choose the module to match your motherboard, operating system and processor. If you want to replace the RAM in your computer, you should first read the memory. Find out which module is currently installed in your computer.
Very important is also the memory speed, especially for game software. Also, look at the clock frequency. There are many modules that now offer a clock frequency of 800 to 3,000 MHz .
Furthermore, the memory speed is important. Some memory have particularly high memory speeds. If you only need your computer to work , then 4GB are quite sufficient. If you use a gaming computer, then the storage capacity should be at least 8GB. If you want to edit videos or pictures, you need even more storage capacity.
Also the compatibility is relevant : Make sure that you have enough slots on the mainboard to plug in the workloader.
Incidentally, a very good recommendation is RAM from Samsung. But it does not always have to be a top brand. The cheapest RAM memories are sometimes even the best RAM in tests.
The memory must match the mainboard of your computer . Otherwise, you can not install the latch.
6. Installation of a RAM memory
Do you have knowledge in the field of hardware and have you put together your own PC or would you like to upgrade it in general? The installation of a main memory is not particularly difficult.
The motherboard specifies the RAM type and maximum clock rate. Furthermore, it can not hurt to know that two memory bars always work better than just one. In so-called dual-channel operation, the main memory operates much faster. The bandwidth is doubled in this way. So it’s best if you buy two equal memory. In this way you reduce potential problems.
Installing Memory: First you need to turn off your computer and disconnect it from power. Then open your PC and get an overview of your RAM. Next, remove the old memory latch. There is a safety lever on the side or end of the rail. Now you can carefully remove the RAM memory for emptying.
If necessary, clean the new memory and gently push it down until it clicks on the safety lever. Only then is the RAM properly installed and in contact with your motherboard.
Now start your computer and check your memory. You can also use a RAM diagnostic tool. If everything works and the RAM does not fail, you can reboot your PC. Disconnect your PC from the power once again. A download or apps are not required for tuning in the form of DDR4.
The memory of the laptop is similar. To empty, remove the old RAM memory and replace it with a newer main memory . Many laptops are sold with very low memory. It therefore makes sense to expand the memory later. Especially if you are often using your laptop , a large amount of RAM is required. Sometimes it may be that the main memory is soldered. In this case no further slot is available. You then do not have to remove the existing latch. Before you use the laptop fully, check the memory again for errors.
The in-house installation of PC components has advantages and disadvantages :
- Done quickly
- Individual PC tuning possible
- A little expertise needed
- Possible expiration of the device warranty
Questions and answers about memory
Memory only from brand manufacturers?
PC memory can be divided into computer manufacturers, third-party and no-name manufacturers. The computer manufacturers often advertise that their memory is compatible with other devices of the same brand. This may sound very good at first glance, but this is a classic marketing.
Various tests and comparisons of memory have shown that there are few differences between models of brand companies and third-party providers. In contrast, the No Name manufacturers often advertise with the argument that they offer cheap DDR4 memory. But beware: Often the quality is lower.
Should it be 32 bit or 64 bit?
The 32-bit architecture is common on many Windows computers. However, the possible amount of memory is limited. In a nutshell, the available memory size is limited to only 4GB at 32 bits. Also, if larger memory latches can be installed, your system will only work with 4GB in this case. But if you have a 64-bit computer, there are no limits. You can then install much more RAM memory and then use it.
What RAM is supported depends on the processor of your computer . Also, the chipsets, after some comparisons of random access memories, have a significant impact on what type of memory can be installed.
What about overclocking?
It is also possible that you can operate your PC memory at a higher clock frequency than provided by the manufacturer. The overclocking of other semiconductor devices is possible, as with the graphics card and the processor. So if you want to overclock , you have to do this in your BIOS. Many Intel chips use a standardized overclocking protocol, which prevents manual settings.
However, several tests and comparisons of DDR4 RAMs do not recommend overclocking , because if set incorrectly, the entire system may not work at the same time and the manufacturer’s warranty expires – at least tests were for category DDR3 memory, category 16GB memory and lower Memory quality of 8GB before that.
