NEW RAM TEST SOFTWARE YAART



Myself being a hardware developer, I have always been sceptical about programs like the "Marpet RAM test" software along with the Atari diagnostic cartridge in finding faults.  I always have suspected faults (bad RAM) where no software would ever seem to report such errors.  These errors were basically impossible to track down and bugged me for a long long time.

I made a plea for someone to write a good fast RAM tester program and  Christian Zietz of CHZ-Soft came to the rescue and created YAART aka  "Yet Another Atari RAM Test".

Don't let this innocent sounding name fool you! It is by far the best RAM test software I have used and really gets down to business in tracing faults!  These days I couldn't live without it!

A quote from the website..

"The storage test programs available so far for the ST disrupt that they are usually very simple knitted. Obviously, you will find obvious problems with the RAM, but not subtle errors that occur only after many passages or with certain test patterns. For the PC, there are Memtest86 software, whose test algorithms have been specially optimized to find such errors.

I have now decided to implement some of these algorithms in a test program for the Atari. YAART ( Yet Another Atari RAM Test ) was developed. From the test depth I think it is already better than many other RAM test programs for Atari TOS.

YAART is available in two versions: YAART.TOS is intended exclusively for (mega-) ST (E) computers, but it can also test memory that is already occupied by the operating system or other programs. YAARTTT.TOS, on the other hand, tests only unoccupied memory, but runs on all Atari-compatible computers (eg TT and Falcon) and tests TT-RAM as well as ST-RAM."


I have being using it for some months now and it really does find errors which no other RAM tester program has even been able to find.  It's not often I get excited about such things, but YAART has to be one of the top software essentials to have!  

So HUGE THANKS to Christian for creating this fantastic program!

  1. I used MemTest86 for years, I have had that say there are errors even due to the slot configuration of the dimms sometimes good to have it though, much more useful than a £1000 ram check thing.

    Glad to see such a app for the ST. I had a Amiga one which only tested the memory on the board it came with and did not test the Amigas own internal chip memory or other memory expansions so a bit useless :/

    1. I really like memtest86, it showed RAM errors when no other program would. Then they made memtest87 and changed all the tests and made it totally useless :( I thought I was going mad, 86 would list faults and 87 would never find any.

      So really glad I now have a ST version of memtest86! A serious bit of software which is exxos approved ;)

    2. I had another version Memtest 86+ cant remember why I needed it, it does something different but I cant remember what :p

      Oh I think the text is a dif colour :p
