How to identify and fix a malfunctioning RAM. Why the RAM is warming up Why the RAM on the laptop is warming up

But in any case, this is only a temporary solution to the problem and either you do not value your data, or you are lazy. Therefore, the most correct decision is to disassemble and remove dust.
If you do not know how or are afraid, then it is better not to poke your nose. Because after that, it may not turn on at all.
On my own behalf, I will add only what I disassembled and cleaned the laptop the other day. Replaced thermal grease and cleaned the "passage" in the vents. As a result, the laptop became much less hot (before the hand was already "burning" near the "air outlet") and became almost noiseless (well, still, the poor cooler (fan) tried its best to spin as fast as possible to push hot air through this layer of dust).

Oddly enough, but the RAM is also overheating. The RAM node is also capable of overheating, so it is worth considering the causes and consequences of this process. When the RAM heats up, this can cause a number of malfunctions and errors in the operation of the device.

If the RAM overheats, then it burns out and can no longer be used, since it simply will not work.

For this reason, overheating of the RAM should be combated and prevented. RAM cooling is achieved different ways, from installing a cooler to using liquid cooling. It all depends on the model of your computer and how modern it is.

To begin with, you can consider the option of installing a radiator in the case when the RAM is warming up. Heat exchange occurs between the parts of the device and thus the operating system is cooled.

I would like to note that heating is not always worth fighting. It is best to deal with overheating of the device in order to avoid unpleasant consequences.

RAM has a rather complex device and therefore we will not consider its structure in detail, since this is not the topic of the article. If you have problems with the RAM, be sure to take your computer to a service, where they will carry out diagnostics and establish the problem of overheating.

Self-repair or installation of a cooling system in order to eliminate overheating usually does not end well. Therefore, without professional skills, you should not even think about self-repair or upgrades.

Reasons for overheating of RAM

When the RAM heats up, you should think about whether something broke for you for an hour. In case of detecting overheating of the RAM, it is worth knowing a few important points... Firstly, the RAM has several contacts, when displaced, overheating can occur.

If the voltage flows are uneven and plus goes to plus, then of course, the RAM will warm up.

Also, the reason may be that the case is poorly ventilated, the air flows in it do not circulate, and the warm air is not cooled. In this case, you should check the entire cooling system of the system unit and make sure everything is in order. Otherwise it is worth contacting the service to troubleshoot RAM problems.

The RAM is heating up, is the radiator a way out?

Heating the RAM to a critical temperature for us, for example, 85-90 degrees is sometimes normal. If the RAM heats up to such a temperature and functions adequately, then it is comfortable for it. Heating the RAM is not always a flaw.

In this article, I will go into detail on how to diagnose memory problems. We will also figure out how to fix and replace RAM using the example of a PC, laptop, and on Windows examples and Linux.

I will try to describe everything in detail and clearly. Therefore, beginners will be able to figure it out, and experienced users will find something interesting for themselves.

Terms:
RAM is the official name for random access memory.
RAM bar - a microcircuit, which is a random access memory.

How RAM can go bad

Random access memory is a microcircuit inserted into a special slot in your computer or laptop. Naturally, there is more RAM in a computer, and less in a laptop. The RAM bar is the most reliable piece of hardware in your computer or laptop. According to statistics, they are the least likely to break, and therefore the warranty period for them is longer (on average - 4 years).

This is due to the simplicity of the microcircuit. It practically does not heat up, and therefore it does not need a cooler (fan). In rare cases, a radiator is put on the operating room for cooling, but this is usually found on powerful gaming computers... In addition, the heatsink makes the RAM bar structurally stronger.

RAM can only be physically damaged. Those. not a single virus or software problem has yet been able to taint the RAM. Therefore, the causes of the problem are most often:

1) Manufacturing defects.
2) Problems with the power supply.
3) Mechanical damage to the RAM strip or connectors.
4) Static stress.
5) Simple wear and tear.
6) Overheating / hypothermia.

Manufacturing defect is rare. In 1% of cases, and this does not greatly depend on the manufacturer. This is due to the fact that all microcircuits are checked by the manufacturer. In addition, the warranty period for RAM is long. Therefore, it is enough just to go to the service center and change the RAM bar under warranty.

Power supply problems are rare. In power supplies and maternal memory there are controllers that do not allow the output of a voltage greater than expected. However, there are times when it is a voltage failure that spoils the RAM. Unfortunately, this can only be checked with a voltmeter, which most people do not have at home (but in vain). If the problem is in the power supply, then you will have to replace it too.

Mechanical damage- the most common case. This usually happens when you try to force the RAM stick in. Sometimes it is not the microcircuit itself that is damaged, but the connector.

Static stress is extremely rare. In my practice, I have never encountered such a thing. System unit the computer and the laptop case are always closed, and therefore static electricity is excluded. Moreover, in modern devices there is an antistatic mesh under motherboard... However, static electricity can become a threat. For example, if you walk on the carpet in rubber slippers, and then climb your hands into the "insides" of the computer.

Simple wear happens over time. Nothing in this world lasts forever. The RAM bar can deteriorate both after 4 years and after 15 years. It all depends on the operating conditions and the manufacturer.

Overheating or hypothermia can also ruin the RAM. But this rarely happens, since absolutely exorbitant temperatures (+ 100C, -45C) are required to ruin the microcircuit. Clean your computer and laptop from dust and everything will be fine.

How to fix corrupted RAM

No way. If the RAM bar is damaged, then it is almost impossible to fix it. If the matter is in the connector or worn out contacts, then you can do something else. However, the microcircuit itself cannot be repaired in any way, it can only be replaced. Fortunately, they are inexpensive. 2GB at 1600Hz cost around 1,500 rubles, which is quite a bit considering the warranty period. Just try not to buy RAM with less than two years warranty.

However, don't be intimidated. Problems can be solved.

What signs indicate a defect in RAM

Common signs:
1) The system does not start. Or it starts to reboot itself endlessly, trying to start normally.
2) The system does not start at all. Usually accompanied by beeping. This means that the RAM was not detected at all. This means either a very severe damage to the RAM strip, or damage to the connector.

Windows:
1) crashes blue screen of death. Blue screen with technical information... The error code is most often different. That is, it makes no sense to google the error, because the codes are always different and always show a different reason. Sometimes this happens due to the fact that the RAM bar is not fully inserted.
2) System malfunctions. This is usually associated with programs and games that use RAM heavily. A vivid example: programs, browser and games crash with a system error. Sometimes accompanied by a crash into a blue screen.

Linux:
1) System malfunctions and program crashes. Sometimes it's funny. You go to the browser, it crashes with an error, you try to view the error report, but it also crashes with a system error. Even if you look at the logs, it is still not always immediately clear what the problem is. It is common for all debian-derived distributions.
2) The system does not boot. Crashes to the console or writes an error. Although it may be for some who use Arch or LFS, it is intended :)

How to check RAM for defects

The easiest way to check the RAM is to download and install it on a USB flash drive or CD (does anyone else use them ?!) special utility Memtest86.

There is Memtest86, and then there is Memtest86 +. The difference between them is small, so you can download any on the official website: www.memtest.org

This archive contains an automatic installer for a USB stick. Those. insert a USB flash drive, run the program and follow simple instructions... Then you insert this flash drive into your computer or laptop, boot from it and check the RAM.

If you are on Linux, Memtest86 comes bundled with images for Debian, Ubuntu, Fedora and a few others. And also the utility can be launched from the grub menu at startup. If you don't know what grub is, then it's too early for you to start using Linux :)

But! Before running the program from a USB flash drive, you need to do the following.

Step 1.
First you need to find the microcircuit. This is easy to do. The RAM looks like a rectangular microcircuit. It is longer for a computer, shorter for a laptop.

The microcircuit is clamped on the sides (tautology, yes). The clamps are easy to open, and then pull out the RAM bar. But before pulling out the microcircuit ...

Step 2.
Reset BIOS settings. When you start the system, press Del and exit BIOS menu... Select the Set to Default option (by default F9 or F10). Then save and reboot.
This step is optional, but the hardware repair philosophy suggests this step. In some cases, resetting the settings helps the system to work.

Step 3.
Pull out the RAM chip and look at its condition. If the contacts are dirty, take an eraser and gently wipe them along.

Step 4.
If you have one bar, put it in the slot and run Memtest from the USB flash drive. If you have several RAM chips, then leave one and take out the rest.

Step 5.
By running Memtest, it will immediately start checking the RAM. It looks like this:

In the image, I marked the program zones with color.
Green - the characteristics of your processor (CPU).
Purple - the stage of verification and the percentage of verification.
Yellow - the model and characteristics of your RAM. Remember them or write them down, because if you want to buy a new RAM strip, you will rely on these characteristics.

If the program detects errors, it will mark them in red. Even one mistake is already a reason to replace the RAM.

Step 6.
After checking, turn off your computer or laptop. Then take out the RAM again and insert it into another slot. Run Memtest again.
If the errors appear again, then you need to replace the RAM bar, tk. it can't be fixed anymore.
If no errors appear, then the point is in the connector.

If you have multiple RAM chips, check each one in turn. If the matter is in the connector, then simply do not use it, or take it to the service - to fix it.

Problem solving

If Memtest gives red errors, then your RAM can no longer be cured. Buy a new one.

Of course, if there are not many errors, then you can continue to work with this RAM bar. But as soon as some program stumbles upon a damaged sector, glitches and crashes will begin. If you use Linux and can compile the kernel yourself, then relying on the data from Memtest86, you can build a system that would not use the specified areas of memory, avoiding errors.

However, remember! If Memtest86 has detected errors in memory, then the wear process has already started. This means that over time, there will be more errors until the RAM finally deteriorates.

Replacing the RAM is simple. You pull out the damaged microcircuit and carefully insert the new one. In laptops, the RAM bar is inserted and pulled out at an upward angle. Those. you insert the RAM diagonally, and then click on it from the top, until it clicks. And if you squeeze the limiters, then the microcircuit itself will "jump" upward.

If you have a laptop with non-working RAM, then it is better to take it with you to the store right away. There, you can ask the consultant to install RAM in your laptop yourself, if you yourself are afraid. In addition, you can immediately test the operation of the new memory strip by taking with you a flash drive with Memtest86 +.

conclusions

If you do not understand something or have any questions, then leave them in the comments to this article.

But, in general, it is not so difficult to test and replace the RAM. It's just that ignorance scares away, and therefore the main thing is to cope with fear. After all, computers and laptops are arranged as logically and simply as possible, surprisingly.

Laptop, simple games, online games, browsers, etc. at startup, the laptop hangs on dead and does not respond to any commands except to turn off, what is the reason?

Hello. Turning on the computer this morning, it beeps long and repetitively. Is it RAM? thanks

When I start the computer, the blue screen "Eror: 0x0000007E" crashes, I think that this is a problem with the RAM, although I installed it half a year ago

Hello, at startup it beeps 3 times .. All the contacts are believed, the video card is working .. RAM planes 2, included one at a time and the slots were changed ... Before that, it started normally without problems .. What could be the problem, the screen does not react in any way ..

Hello, I have such a problem, I was playing in a laptop, he was without a battery and accidentally pulled the power cord out of the socket, it turned off and does not turn on, the Caps lock key flashes three times this is a malfunction of the memory module I replaced the RAM but there is no sense all the same tell me what to do ?? ? Many thanks!!!

The second RAM slot in the lenovo g505 laptop does not work, I insert the RAM, I turn on the laptop, the laptop turns on the black screen, what is the problem, explain who knows

The text is quite bearable, only the RAM bar itself is not a microcircuit, but a circuit (or board), and the microcircuits are those square black things on it.

Good day. I have such a problem: Nout Toshiba - when starting games after some time (10-30 minutes. It happens even more) the system just gets up and does not react to anything. The same problem when you watch movies online. Tell me what could be the reason

Dude, you are awesome, helped out

Good day! Such a question has matured. I have 4 bars for DDR2, 2 for 1 gig, 2 for 2 gigs, despite the fact that one manufacturer and one frequency. if you put them separately (2 to 2/2 to 1), everything plows, but only on the yellow slots of the mother. and when installing in different slots or installing 4 strips, some kind of failure occurs at once, the system engineer beeps incessantly and does not load the system. What to do?

Thanks for the answer, just a situation arose, we are doing repairs, people came two months later and claim that we allegedly changed the RAM) so I'm trying to figure out what's what))))) the laptop was flooded))

Paul, no, this is hardly possible. The volume cannot change that way, even if the sectors are damaged. It is possible that your equipment reserves part of the memory. Go to Task Manager - Resource Monitor, and see how much is reserved by the hardware.

Hello, such a question, can the RAM partially fail and show 1 gig instead of 4 gigs, for example, is it possible at all ???

Hello! Please tell me, my RAM is working properly, as it was tested on other PCs (intel), but when I insert into my PC (intel), I have a black screen and one long squeak repeating, which indicates a malfunction of the RAM. I put the dice one at a time and different slots, the same 1 long squeak. Also on the motherboard there are 2 swollen capacitors near the processor socket above it and on the left, can this be the cause of the malfunction? Or is it the RAM slots? I hope I explained it clearly! Thank you in advance!
