How to diagnose the state of your RAM on Windows, Linux and Mac

Sudden reboots, programs that fail randomly, windows that close apropos or blue screen. The problems caused by the malfunction of the memory modules RAM can be as generic and random that sometimes costs relate RAM itself. Although other failures are much less subtle, and you can find screens reporting that the memory system fails.

Whether because you are convinced that the RAM goes wrong, or because you are simply by detecting small glitches and want to discard it by your memory modules to give with error, it will come in handy to have on hand programs to diagnose the state of your RAM . Today we will show you some that you can use in Windows, Mac OS X or Linux.

Windows Memory Diagnostic

Windows takes time taking a simple but complete tool to analyze your RAM called Windows Memory Diagnostic. It may not be as thorough as other alternatives, but at least it will serve to give a first step before Liard to downloading software, and all you'll need is to restart your computer.

To run you just have to open the Start menu and type mdsched.exe or the full name of the program. You will see a window like the catch with only two choices, scan your computer immediately restarting the computer or to schedule scanning of RAM for the next time you restart appears.

the circumstances in which you do your next reboot (maybe you hurry) You never know, so it is recommended to immediately analyze the RAM. In doing so the computer will load a screen that shows the progress of the test. Will warn you of mistakes, so if nothing happens maybe your memory is good and the problems you are giving the other component or application

Memtest86 +, the most comprehensive Windows and Linux

 But if you prefer to leave behind local trials, Memtest86 + is the most complete and popular tool you can find for Windows or GNU / Linux. It is open source, and gives you the option to download a simple installer for Windows that create a USB or download an ISO image that you can burn on any removable drive regardless of your operating system.

Once you have created your external drive, to run the program will have to shut down your computer and start the USB or CD from the BIOS by pressing the assigned on your computer to choose the drive from which you boot key. Usually the F8, F11 or F. If not atinas enters directly into the BIOS setup and alter the boot order by first choosing the USB or DVD in which you have the test.

Memtest86 + has up to eight different tests to analyze your memory, and if you're going to do them all to locate a possible problem will have to spend a few hours. In addition, it is advisable if you have multiple memory modules is to go by analyzing each separately to optimize results. By the way, the results of this test may not indicate failures in RAM only, but also on your processor or motherboard.

Two more options for Windows

 If you only use a Windows operating system you have two more options. The first is Memtest. Yes, it is exactly the same open Memtest86 +, with the difference that is only for Windows (from 9X to Win 10), and do not need to restart your computer to use program.

Just download it, unzip the file and run it. But of course, in doing so you'll find yourself with Windows' own limitations, and the program will alert you that you have a limit of 2047 MB of RAM used by program, so you have to open several times the application and run the test with all to while if you want to analyze more than 2 GB. The free version is useful but basic, so you also have an option to purchase two advanced versions with more features.

Another program you can use is DocMemory. To do also have to burn it to a CD or USB and run at system startup, and with it you can analyze up to 64 GB RAM or CPUs from Intel and AMD. Supports DDR, DDR3 and DDR3 modules, and if it seems very simple also has a PRO version with advanced features.

If you are a Mac user you have several options

 Quiet, because if you're using Mac OS X also have several options to determine if RAM is the cause of these annoying errors giving your software. Two of the main options are the internal Apple Hardware Test tool and some third-party programs like veteran Rember.

And of course, the open source tool Memtest has also found its way to Mac OS X. Memtest The application is automatically installed in the / applicatons / memtest, and to execute will have to restart your Mac while holding down the Command-S key . a console It will run automatically, and it will only have to write the / Applications / memtest / memtest all NUMBER -1 command.

Linux also have another option

 If you are too lazy to restart or for any other reason you do not want to use Memtest 86+ to analyze your memory having an operating system based on GNU / Linux, you have another option that can be run directly from the command console and without restarting the computer. It is called memtester and has versions for Debian, Ubuntu, Fedora or NetBSD.

I will explain the steps to use Ubuntu because it remains the most popular distro. Enter the terminal and type sudo apt-get install memtester. Then type sudo memtester XGB, with XGB the amount of memory to be tested. You can also put MB instead of GB. The problem with this application is that it can fail because having to run with a running operating system can not analyze all memory.

Once located the problem

Once located the problem touches change RAM. In this video from Engadget TV in which we are taught to assemble a PC by saving money pieces you will see how you insert or remove your RAM to the motherboard. Also some other tips you have to keep in mind when changing parts of your computer.

But if you are going to be unhappy having to change the RAM and want to do a deeper physical analysis or try to solve the problems, some companies offer professional solutions pay for it. Some of them are physical or Memory Testers analyzers and other solutions that can become quite expensive as PC-Doctor, PC Diagnostics or Ultra X. Several of these tools are also used to analyze other physical components.

This system will monitor glasses and contact lenses and diabetes drugs supply

It's funny how some conditions continue to use treatments that are based on techniques used for several decades, the best example is diabetes, where sufferers need to regularly monitor their glucose levels by pricking, an invasive technique and annoying for most people, but today, except for some development projects, remains the most efficient way.

Two years ago unveiled a project between Novartis and Google consisting of a "smart" contact lens, which would be equipped with a sensor to measure glucose and send the information wirelessly to a smartphone. But now we find an interesting twist to the idea of Google as just presented a system of lenses and glasses that together would measure glucose, but also be able to release small doses of medication if needed.
Improving the quality of life of diabetic patients

Sae Kwan Hahn, a professor of materials science and engineering at the Pohang University of Science and Technology of Korea (POSTECH), has just presented the project at the World Congress of Biomaterials, which has attracted attention because it could not only help diabetic patients, but could also be adapted for other diseases and their treatment, as the case of glaucoma.

The system consists of a lens made of two layers of hydrogel soft silicone, the circuits are installed on the lens ring where we have a sensor electrochemical glucose, a microcontroller chip, a delivery system of drugs and an induction coil, which it is responsible for providing power for wireless communication. On the other hand, the glasses will be connected at all times to the lens, as they will be carriers of the drug that would accommodate a dose month.

When glucose levels increase, the chip sends a wireless signal to the glasses to release a dose of medication, plus the glasses will have a small LED will light if glucose levels are too high and require user intervention.

 In the first demonstration system, drug release was not automatic, the illumination of the LED the user has to use voice commands to deliver the drug, but it is expected that in the future this can be done automatically, so that the patient forget for a moment your treatment and try to lead a normal life.

In the first tests a solution of artificial tears to know the behavior of the system was placed, and the three people carrying a prototype for three weeks, not accidental drops of liquid were presented, the dose was precise and without any damage. Its creator is sure that there are companies interested in its development and it could see the light during the next year, and that thanks to that could take up to a month dose glasses could be used in a wide range of treatments.

More evidence of a future Apple Car

Technology that focuses on an electric car charging looking for specialists

Apple continues his career, relatively quiet, to enter the world of transport. The course Apple Car remains departure but begin to leak details of its commitment to electric power. After almost a year of rumors, Reuters has unveiled the plan to have power stations. Having a reliable network is one of the keys to the adoption of the product against the established network of gas stations worldwide. After the decline of iPhone sales, its most successful product, and stabilization of the iPad, the tablet, Apple seeks a new bombshell to remain at the forefront of innovation.course Apple Car remains departure, but begin to leak details of its commitment to electric power.

Having a reliable network is one of the keys to the adoption of the product against the established network of gas stations worldwide. After the decline of iPhone sales, its most successful product, and stabilization of the iPad, the tablet, Apple seeks a new bombshell to remain at the forefront of innovation.

According to information from the agency, Apple has had approaches with manufacturers of car charging systems and are working closely with employees who already use an electric car to find out what needs improvement and should take into account. Arun Banskota, whose company has a charging system, Reuters has confirmed the interest of Cupertino.

Another indication of this interest is in some of its contracts: BMW signings and a Google specialist, Kurt Adelberger. Before they were done with Ijaz Mujeed services, technical director A123, a company in Massachusetts that has denounced Apple for its aggressive hiring. Johan Jungwirth, director of research and development of Mercedes-Benz also joined the block, and Ford came Steve Zadesky. Internal security, in the form of seat belts and airbags will be the role of Robert Gough. A Tesla they took to David Nelson, John Irelan and Peter Augenbergs, and Lauren Ciminera, a sensible loss, since it was responsible for hiring more specialists.

The challenge of charging stations is one of the keys to succeeding. In California, it is estimated that it will take 20 times more stations than the current 8,000. Tesla already has more than 600 fast, able to completely fill the battery in half an hour. It just unveiled that Mexico will also have an amazing these stations of the future in Cuernavaca.

From Detroit, Chevrolet is the firm whose effort to adapt to this new environment will soon be on the market.
