Memtest86+ 5.01


Memtest86+ 5.01 does not have an interface in the classic sense of the word. It is a small software utility that starts before Windows boots and once it does so it will present you with an interface that strongly resembles a DOS program, like the ones we used to run 20 years ago. This is good news though because thus Memtest86+ 5.01 can really focus on your RAM memory with no chance to be bugged by Windows processes thus giving out inaccurate results. As to the interface itself – expect to see a blue screen that can be divided in two major parts – the one on top lists some basic information on the version of the software and then it presents you with some information regarding your processor, its speed in MHz, the speed of the L1 and L2 caches, the chipset and the memory. The bottom part of the program is left to the results of the test that will be performed.

Basic Operations

There are two main ways in which you can start Memtest86+ 5.01. The first one is by using an ISO image burned on a CD. Just boot from the CD and then follow the instructions. The second way is to have the program decompressed on a flash drive as a binary file – then you can boot from the flash drive. Once you do you will see the interface of the program. Run it and leave the PC to get the job done but beware – the process may take hours. The results will be listed in the program interface and if you don't see text in red your RAM memory is all fine; if you do you should change your RAM sticks promptly as they have problems and can't keep information with no errors inside.


Memtest86+ 5.01 is an excellent utility that can tell you a lot about the current condition of your memory chips. It is small-sized, it never gets installed on your Windows PC and it shows accurate results right in front of you – and it is also free! So if you have problems with your PC download and test your RAM memory with Memtest86+ 5.01 – it never hurts to know how your RAM feels inside your PC.
