[SOLVED] How do these memory tests work?

[Aspect13]

So I was wondering what do these tests actually do and what are the differences. Which one is the slowest and why and which one is the fastest?

1. MATS+

1. Stride38

1. WSCHKR

1. WStride-6

1. CHCKR4

1. WCHCKR3

1. ERAND

1. Stride6

1. CHCKR8

What do you want to test?

 

[Aspect13]

My memory

Use memtest86

 

[SamirD]

Yep memtest86 is the best and can be found on many boot cds/usb too.

i see where these come from - https://sourcedaddy.com/windows-7/how-to-use-windows-memory-diagnostics.html
memtest is better idea

You should have gone to source

How To - How to Test your RAM

How to Test Your RAM Before testing your RAM, you need to know what type of firmware is on your PC. Either BIOS which is usually on pre-2012 PCs or UEFI which is usually on newer PCs. You can find this information in your motherboard manual. Or, run msinfo32.exe and look for BIOS Mode...

For physical memory test memtest86, for in place (under windows) testing https://www.techpowerup.com/memtest64/ which also tests how system is handling memory (including IMC) etc. because even perfect memory can be unstable in real work.

I don't know what each of those test apps do exactly, but most memory test applications will do a pattern fill of some sort (like all 0s, all 1s, or alternating), do a read back, and compare what the RAM gives them.

As far as which one is faster or slower, it's sort of irrelevant in the sense that it depends on how confident you are with the results. A faster test usually means the RAM wasn't tested as much than a slower test. For example, one app may do a single pass over the entire memory space, but another may do it multiple times for confidence. Obviously doing multiple passes is slower, but if it comes back with no errors, then you can be more confident that the RAM doesn't have a problem.

i would love to tell you what each test did but that seems to be hidden knowledge

no where spells out what all tests do, at least Memtest shows you a description of what its doing.
