RAM problems. Problems with RAM Added RAM computer does not start

Question: The computer does not work with new RAM

Good day to all.
Please help me figure out what's wrong. A week ago I bought myself two Kingston KVR16N11S8 / 4-SP RAM sticks on 4Gb in the online store (Brand Star). I was very “lucky”, on the day of ordering they were in the store's warehouse, to celebrate, I dropped all my business and went to the store as soon as I bought it, flew out of the store with a feeling of euphoria and almost ran home with them. With this feeling of joy, he quickly disassembled his computer, pulled out the old slats, carefully put them on the shelf and decided that I would take them to the dacha in the old computer. I put new ones, assembled the computer, set it down, smiling from ear to ear, settled comfortably in a chair, pressed the power button ... and then the feeling of joy immediately flew into oblivion, the smile slipped from my bewildered face, somewhere on the floor. The computer rebooted cyclically, preventing the entry into the BIOS. Not understanding what it was, I disassembled the computer and installed only one new bar, with one bar the computer boots and enters the BIOS, the computer boots only up to the Windows logo and again, and again rebooted in the same place. Having decided that the problem was in the OS, I found my old USB flash drive, for such cases, and began to reinstall Windows, set all the parameters in the BIOS, boot from the USB flash drive, the boot logo and bam! Reboot. I set the timings (11-11-11-24) ... Nothing comes of it. He spat out of anger, set the old standards. Turned on the computer, saw the desktop, turned off the computer. Dear friends and comrades, tell me how to start this damn new RAM?

Any problems with RAM are not as common as with other computer components. But all the same, they do happen and you need to be prepared for this. When problems with RAM make themselves felt, it can manifest itself in different ways: again - "BSOD" (English Blue Screen of Death), spontaneous computer restart, "freezes", etc.

Note: "blue screen of death" looks something like this.

It can appear not only during problems with RAM, but this is one of the sure signs that unambiguously "speaks" that something is wrong with the computer and requires the intervention of a specialist, ie. - US! :)

If RAM does not work, then there can be two options:

1. The RAM is completely burnt out. In this case, when turned on, all the fans of the system unit rotate properly, but the system does not give further signs of "life".
2. The RAM is partially out of order (malfunction of one or more of its chips). In this case, the situation is not so obvious, the Computer can successfully load the operating system and even work stably for some time, but when trying to run any resource-intensive application it will restart, freeze or show BSOD.

In the second case, it is necessary to conduct a full test of the RAM for errors in its operation. This is done using special programs and today we will talk about one of them. Personally, she never let me down. Meet! A wonderful utility - " Memtest».

Here's how the testing process looks like in it:

To identify problems with the RAM, the program sequentially runs eight tests, each of which loads different parts of it, writing different values to them, reading and checking against the standard. We can see the progress of all these tests in the upper right corner in the screenshot above.

If during testing errors were found in the memory, they are displayed in red in the middle part of the window.

The screenshot above shows that this memory module is no longer alive! :)

Problems with RAM are solved, as a rule, by replacing its unstable module (normal operation with it will still be impossible to achieve). Although we continue to use some of them successfully in our work. How? In terminal clients, which we talked about in the article "". In this case, there is no active exchange with memory, and if no access to its faulty pages occurs, then it can function properly for quite a long time.

As you can see, the program "Memtest" is very easy to use (testing starts automatically after loading), it does not require any additional settings and configurations and does an excellent job with its task.

I want to give you some tips on how to fix problems with RAM:

1. Always test memory only from the boot disk of the program. If you run "Memtest" from under Windows, it may happen that, trying to access the faulty memory section, the program will cause Windows to restart. Do you need it once more? :)
2. If you have several RAM modules installed, then by testing all of them in a complex, it will be impossible to determine which particular module leads to failures. Therefore, we need to test them separately (remove all "unnecessary" ones from the slots and leave only one testable). And so it will be with everyone! ... a module :)

That's all I wanted to tell you today about problems with RAM. By tradition, I give a link to download the program itself "".

Note: after downloading the archive, unzip it. You will receive a "memtest" file with the "iso" extension (this is the image file of the program itself). Now it will need to be written to disk in the image recording mode.

After that, insert the CD into the computer under test, put the boot from it in the Bios and test the RAM.

I recommend that you always test RAM only from under DOS, since it itself uses no more than one megabyte of memory for its own needs and we can freely test the rest of its space. If we start diagnosing RAM problems from under Windows, then a certain part of it (occupied by the system) will be inaccessible to the testing program and the procedure itself will not be as effective.

I would like to say a few more words about the "blue screen of death" (BSOD). It makes no sense to stretch this material into a separate article, but here this information will be appropriate. So, what useful information for ourselves can we learn from this blue screen? Pay attention to the photo below:

We are only interested in the alphanumeric value after the word "STOP". It is this designation that can tell us in which direction to move when determining a particular malfunction. This applies not only to problems with RAM. The values of the STOP error codes themselves are a great variety (depending on the specific malfunction), but according to them you can approximately navigate and save your time when diagnosing.

How can we sort out such a large number of error stop codes? Do not keep them all in your head! This is not necessary. Everything has been done for us a long time ago :) For example, there is one wonderful program "" (you can download it from the link), which contains their database and explanations of errors (in Russian). You just have to specify a specific STOP code and the program will give you all the necessary information.

Let's specify our value: 0x0000007A

In this case, the code indicates to us problems with RAM. I know this for sure, because this is an example from my recent practice :) The program can update the error base from the manufacturer's website, so pay attention to the "Updates" item.

I would also like to tell you about this moment: is it possible that during the installation of the operating system you saw a message similar to the one shown in the screenshot below?

V 99 cases out of a hundred (we will still write off one of the fact that the installation disk is really dirty or scratched) we are dealing with the same RAM problems. Naturally, the name of the file that the system cannot copy can be absolutely anything, since it is at this stage of installation that a large amount of data is copied into memory and some files are trying to write to its faulty cells.

Now - a few general recommendations so that problems with RAM do not bother you, remember that memory, like any other node to which voltage is applied, heats up and its overheating can negatively affect the stable operation of the system as a whole.

Personally, I decided for myself this way: a couple more small fans in the system unit - it doesn't matter! :) What am I leading to? There are various systems for cooling RAM on the market. These can be either slip-on heatsinks that are attached to both sides of the memory chips, or they can be small prefabricated cooling systems that are equipped with fans and are fixed directly above the memory slots.

Here, for example, I use such a "Kingston HyperX Cooling Fan" cooling system in my.

In the disassembled state, this is an elementary children's designer, which must be assembled and fixed on the white latches of the slots by sliding apart (in the direction indicated by the arrows) the aluminum fasteners of the device. The device is connected to one of the fan turn-on connectors on the motherboard.

In addition, the device has a nice LED backlight :)

The situation looks like this: very often, when assembling a computer, RAM modules are installed in the nearest (to the processor) slots. If I see this, then, if possible, try to immediately rearrange them away from the processor (third or fourth slot). Why am I doing this?

According to my numerous observations, it is the first two RAM slots that are most susceptible to dust. This is due to the active cooling system of the processor (fan), which evenly distributes dust within a radius of 5-7 centimeters from it.

More than once, all the "repair" of a seemingly seriously inoperative machine for me boiled down to reinstalling the memory in another slot (with preliminary clearing of the latter).

Dust is the enemy of any electronics! Sometimes it can accumulate inside a lot and - nothing, and sometimes - very little on the contacts and the complete inoperability of the entire system. Cleaning can be done with a soft brush or paintbrush. As shown in the photo below:

Take a good look at the grooves in the connectors, because this is where the electrical contacts are located. So that problems with the RAM do not annoy you in the future, also clear the "tracks" on the module itself.

Personally, I use an ordinary rubber band for this.

Thoroughly wipe all leads with it (move the rubber band parallel to the copper contacts in the direction indicated by the arrow) and you will notice that the contacts immediately become lighter, and therefore the electrical contact is better. Install RAM away from the CPU cooling system and let your computer run for a long time and without failures :)

P.S... I thought about it and decided to supplement the article a little more. The topic, it seems, is not directly related to RAM problems, but, I hope, it will be useful to readers. What program will you write the "iso" image that I posted above? If you answered - "Nero", then - read the text further :)

Previously, I also used this software, but then I began to notice that its distribution with each new version is increasing and increasing in size. And it came to a paradoxical situation: in order to simply burn a disc, I had to install a 300 megabyte software package on my computer!

Realizing that this could not continue, I began to look for an alternative for myself. I found it in the form of a wonderful crumbs called "img itemprop =" image "Burn". Its size is just under two megabytes. She perfectly writes discs and I had a case when she (no questions asked) burned me a CD image in 800 megabyte to DVD, while our "folk" three-hundred-meter package needed some additional plug-in for this "complex" operation :)

So, without further ado, I sincerely recommend you this little helper "".

Question: Does it make sense to add RAM

Good afternoon, I want to ask a question about whether it is worth adding RAM to a computer with the following configuration:
Pentium G840 Box Processor
Motherboard S1155 MSI H61MU-E35 (B3)
RAM DDR3 2048Mb DDR1333 GoodRam 2 strips (4 GB of RAM in total)
Video adapter PCI-X GeForce 450 GTS 1024Mb MSI DDRS (N450GTS-MD1GD3)
The computer has 2 slots for operational memory, I want to put 2 4 GB strips for more efficient processor operation. Will the performance of the computer increase if I change the RAM from 4 GB to 8 GB ???
Thank you in advance for your response.

Answer:

Message from Danil6

Will the performance of the computer increase if I change the RAM from 4 GB to 8 GB ???

No. The amount of memory will not improve the performance of the processor.
Are you using resource-intensive applications (photo / video editors and the like) worth increasing.
There is never too much memory.

Question: After replacing the RAM, the laptop began to reboot (I could not find a solution on the site)

Hello! Please help me in solving this problem, which has already managed to shake my nerves. So:
Notebook - Emachines 732ZG

A kingston sodimm ddr3 kvr13s9s8 / 4 ram was purchased with the following characteristics:
Memory capacity 4 GB
Memory type SODIMM DDR3
Memory frequency 1333 MHz
Supply voltage 1.5 V
Effective Bandwidth 10,600 MB / s
Memory Timing Scheme 9-9-9
Tobish, as it seemed to me, should have become like a native.
The system was preinstalled with Windows 7 32bit. I immediately inserted a bar without replacing Windows, 2 slots - in one 2GB, in the other 4GB. Everything worked, but as we know the 32-bit will not use this volume in full. Then I started trying to reinstall Windows and came across a freeze of the OS installer at the start, I thought the image was broken. I downloaded a couple more three and none of them were installed, it just hung. Ok, I inserted the old bar instead of the new one, put in a 64-bit, disassembled the laptop and inserted a new one (for 4GB). The laptop just began to reboot when trying to load Windows, took out a new one, started the OO. I tried to bet in different combinations and in different slots, it didn't help. Then, in the impudent one with the system turned on, he took out the old one and inserted a new one, oddly enough, but Aida and cpu-z identified it, but the Windows showed only the old RAM involved. Rebooted, it gave nothing.
ps Help please. I really hope for you =)
zyy Thanks for taking the time for a lot of letters)

Answer: Delete94,

On your topic, we made a very good zemyak.
I also do not understand the dependence on the chipset, because the memory controller is in the processor. But, hike, yonis78 right!
Intel figs will be interrogated: "Maximum memory size (depends on the type of memory)" - it would be better if they did not write anything.

P.S .:
Why the personal doesn't work, you can't write everything here.

yonis78, look in a personal, what do you think about it?

Question: Computer does not start with new RAM

Good day. The other day I decided to add RAM to my computer. But after installing an additional RAM module, the computer stopped starting.

Here are my ingredients:
Motherboard: ASUS P5P43TD PRO (iP43) S775 PCI-E 4xDDR3 6xSATA2-RAID 1xIDE GLAN 1xLTP 1xCOM 1xPS / 2 1xESATA 1x IEEE1394 SOUND ATX RTL
CPU: CPU INTEL Core 2 Duo E7500 2x2930MHz-1066 3072Mb LGA775
RAM: DIMM DDR3 2Gb PC3-10600 1333MHz Kingston

I bought an additional DIMM DDR3 2048MB PC10666 1333MHz Kingston Retai
The shop assistant said this board should work well with mine.

I ask for advice

P.S. When paired, these two boards do not work, I put a new one separately, it also does not start with it.

Answer: and i have the same problem. Mother ASUS P5P43TD PRO works fine with KVR1333D3N9K2 / 4G memory, and does not work with KVR13N9S6 / 2 memory. And in the store there is no other memory. We'll have to look for a used one.

Question: Optimal amount of RAM

Hello!

I have the following configuration:
Motherboard: GA-P55-UD3L
Processor: Core i7-860
Memory: 2x2GB, DIMM DDR3, 1333MHz (PC-10600).
Video card: Palit GeForce GTX960

In connection with the transition from x32 to x64 windows 7, I am considering the issue of increasing the RAM.
The computer is mainly used for games.
Does it make sense to increase the volumes to the maximum possible in my case 16GB (motherboard limitation) or is 8GB or 12GB enough?
Is the difference between 8GB and 12GB big from a user perspective?

Sincerely,
Sarger

Answer:

Message from quwy

So look in the system requirements of your games, how much they need, and then multiply this value by two

+
I also want to add that for toys, and indeed, there is never a lot of memory. I already had 8 GB of memory 3 years ago. Right now this is not enough, you need to add up to 16

P.S .: when choosing the amount of RAM, it doesn't matter what the rest of your hardware is. Well, unless you need to take into account the limitations of the RAM controller in terms of volume, which can be located either in the motherboard chipset or in the CPU.

Question: Replacing RAM with x79-UD3

Hello Dear forum users!

There was a need to replace the RAM.
Motherboard Gigabyte x79-UD3 rev. 1.0

Memory kingston khx 1866c9d3 / 4gx - 4 x 4GB (16gb in total)

I want to change to hx324c11srk2 / 16 - 4 slats of 8GB each (in total 32gb)
Change, dies and siblocks after 3-5 seconds. goes into reboot, I can't even get into the BIOS.

Tell me what is the problem?

Answer: Today I set the bar.
First one, and then the rest.
It started, only the characteristics (timings and voltage) set in the BIOS parameter do not start the computer.
The same problem, restarting in 2-3 seconds, and does not start up in the BIOS.

I also tried setting up through native profiles, only they overestimated the last timing by 2.
2133- 11 13 15
2400- 11 13 16

Tell me a way to overclock, can I try it through xmp?
It had a sticker "Intel XMP Certified"
Only I didn’t run it through it even once.
Can this be done through Windows?
The computer won't freeze?
Or will it automatically detect the optimal settings?

I ordered Kllisre ddr2 2gbx2 RAM from China. When you try to install memory in both slots, the computer does not boot. Once hung on the BIOS screen. If you remove the memory from slot B, the computer starts successfully. When you move the memory to slot B, the computer does not boot, but if you insert a 1 GB plate into slot A, the computer starts successfully. If you insert one 1 GB bracket into slot B, the computer starts up. Mother ASUS M2N68-AM PLUS. AMD athlon 64 X2 4600+ processor

Answer:

Message from Momadin

The memory worked at a bus frequency of 333.

Thank God. It's good that it started up.

Message from Momadin

I have one more question - is there a big difference between 800mhz and 667mhz in performance?

How can I tell you? If you perform processor-dependent tasks, then there will be a difference, of course. Maybe 10-15 percent. And if the processor is not heavily loaded, then the difference will be small.

Message from Momadin

And it turns out that my memory is now running at a frequency of 667 mhz, although the CPU-Z says that 300.

This is a feature of the work of RAM. On one signal pulse, it transmits two pieces of information. Therefore, the frequencies there in different programs are shown different. In some - the number of physical impulses is shown (300 in your case) and in some - the number of transmitted pieces of information (multiplied by two, it turns out)

Answer: She's not damned, but one-sided. On your 4 GB system, only double-sided strips will work (memory chips are located on both sides of the module, 8 pieces on each side).
