I've got 16mb installed they are 4mb each and this 486 I'm working on has crash problems that look like bad ram from a garbled screen while gaming, I'll adjust wait states later but for now how do I test the ram, I'm betting there is no memtest86+ for dos or is there?

There is, you just need to use an older version.
See here: memtest86 that works for 486
Thanks JJ I was trying to use version 5.01 but I got it working from your above topic with version 4.10
For a quick check you can also use SpeedSys. It tests memory before doing memory benchmarks. I guess it's not 100% accurate.
Requests are also possible... /msg kixs
Not to be pedantic, but either way it's not "for DOS"
All versions of memtest86 are bootable images that do not use DOS, version 4.x supports 386/486 and later versions require pentium
Max I tried version 5.01 as a bootable from a floppy that I had to make in Windows but it kept getting to the "Loading.........." screen then rebooting the pc but it might not be working from bad ram as when I used 4.10 it detected heaps of errors just before it crashed so I'm now up to testing one stick at a time

Right, that's because version 5.01 is not compatible with a 486. DOS has nothing to do with it
I didn't remember in facts how it booted the program and it make sense it's not a msdos boot but probably a more minimal way of loading itself. 😉
