Is not a question of amount of memory used is a question of *how* the memory 
is used!

I really doubt it, perhaps NT can detect kernel corruptions, but it doesn't 
mean it can detect RAM problems.

Here is my experience with RAM problems:

1) There is no way to detect the problem in a consistent way. I tried to make 
a program that allocates ALL the memory and then uses it in various way 
(linear access, random access, butterfly) making various things (shifts, bit 
patterns, etc). The test needs about 40 minutes for 32 Mb in my system. 
Result: NO even a bit failed.
2) Windows 95 works ok with these RAMs. No more hangs than the expected ;-).
3) The only programs that really show the problems are: gcc compiling an 
intensive thing or tar/gzip uncompressing a huge file both under DOS and 
Linux. 

The rest normally works OK.
