Memtest86

I downloaded Memtest86 and extracted the zip file. There is an .img inside the extraction. I believe I can change the .img file to .iso file then extract that to reveal the .exe file.

Is that how it works?

Try
MemTest86+ - Test RAM

Bree · 21 Aug 2019

Are you confusing MemTest86 and MemTest86+. There are two, The '+' version is a fork of the original and is available in a form that can be used by Windows.

MemTest86+ runs under Linux, but for Windows users you can make a bootable USB that contains the OS and MemTest. The link you should download From Memtest86+ - Advanced Memory Diagnostic Tool for a Windows system is called 'Download - Auto-installer for USB Key (Win 9x/2k/xp/7)'.

This contains just one file called "Memtest86+ USB Installer.exe" which will make the USB when you run it.

Bree I did not know there two or more versions of Memtest86. I want to be able to test my RAM on my Windows 10 Home 64bit PC.

So what do I need?

download from Memtest86+ - Advanced Memory Diagnostic Tool by clicking the link called 'Download - Auto-installer for USB Key (Win 9x/2k/xp/7)'.

This downloads a file called "memtest86+-5.01.usb.installer.zip". This contains just one file called "Memtest86+ USB Installer.exe" which will make the bootable USB when you run it. Boot from the USB to run the tests.

@huffman -

There's really little point to testing if the ram slot is damaged or the memory stick cannot be seated.
The tolerances for proper contact are extremely close.

Just a suggestion -

Remove the RAM and get a good flashlight and magnifier.
Check to see that each pin is evenly spaced and not bent in the memory slot.

It's delicate.

If OK, then you have to deal with the clamp issue to ensure that the module is properly seated.
Need to check the memory module, too.

FWIW.

OK I download the Memtest86+ USB Installer. I ran the exe file and it indicated it had installed on a new thumb drive.Here is what I see on the thumb drive:

Which of these will run Memtest86. Any of the files selected ask what to open them with. I have no idea what to use to open any of them.

What am I doing wrong?

The USB contains Linux boot files and the Linux executable for MemTest86+. You must boot from the USB in order to run MemTest86+ under Linux. Just boot from it, MemTest will run automatically on boot.

Exactly how you do that depends on which make and model of PC you have. Many have a one-time boot menu you can get to at start up by pressing a function key, often F12, as soon as you see the OEM logo. Then you can choose which device to boot from, if the USB is plugged in it will be one of the available devices. It has to be a full start up from cold, so if your Windows has fast startup enabled you'll need to do a Restart rather than a Shut down.

On some PCs you have to go into the bios at start up and change the boot order to put the USB before the hard drive.

What make and model is your PC? The manual should give instructions for booting from a USB. Tell us what you have and we may be able to find the manual for you.
