I have seen people refer to Memtest for memory testing. What exactly is this
test? Is it free? Can it be downloaded? How does it work and what results
are expected etc?

The truth is out there. You just have to look in the right places and ask
the right questions.

Not to dig on the OP or anything, but sometimes I wonder why people
don't use google more. Neither one is difficult by any stretch of the

than posting a usenet message. Certainly much less typing!

My favorite part is where they get pissed off at you for suggesting it.

A software Ram test program.Not very useful in real world testing

Seems to have many instances where 'false' errors could be observed, also.
If I needed to test memory, I'd take it to a local shop with a DIMM tester.
Either that, or do it the old fashioned way :)

I agree or if I have known good sticks of RAM around windows itself is
pretty good(or bad if you like) at detecting faulty RAM e.g Registry
fault calls are a dead give-away.

It's available from www.memtest86.com, and
www.realworldtech.com/page.cfm?ArticleID=RWT120901222920 said it was
great, with only one cheap diagnostic receiving higher marks, Gold
Memory (www.goldmemory.cz). They also said that DocMem (free from
www.simmtester.com) was pretty bad. In my limited experience, I've
found all of this to be true. MemTest86 has found dozens of errors in
memory that DocMem said was fine, and most recently with a Kingston or
K-byte 256MB PC2100 module, every one of MemTest86's cached tests
found tons of errors, but only one of DocMem's tests found anything
wrong. However it's important to run any diagnostic for a long time
because MemTest86 once ran for 4-5 hours before it found any errors,
but Gold Memory always detected the same errors in less than two
minutes (full pass takes 20 min for 256MB PC2100 DDR).

It used to be that all the name brand memory modules I bought worked
and tested perfectly and the only modules that ever gave me problems
were the cheap generic ones from Fry's with chips that had no markings
(or just the size, i.e., 32M x 8) or funny markings (mystery module
maker's name on the chips), or funny brands (Spectec, LEI, Mystic).
But more recently I've found chips like them on Kingston and K-byte
modules, and I've heard that even PNY is using them. So it's probably
a must to run MemTest86 or Gold Memory for 24 hours in a row on any
new memory before putting it into regular use.
 
I was suspicious about some memory recently (2 lots of 256). I seemed
to be having too many BSODs. I checked with memtest and docmem. Left
them chugging away for some hours. No faults reported. later, I tried
to install linux (Mandrake 8.0). It kept failing with Sig 11. I found
out that this could be caused by faulty memory. So I tried again with
each memory module in turn (trying different slots as well). It
consistently failed on one module and succeeded on the other.
So, in my experience, trying to compile a linux kernel is a good test
of memory.

As per my post.Software RAM testers aren't really worth the download
in my experience.

I've seen both -- passes testing but fails real life, passes real life
but fails testing. You can't rely on only one method, but real life
programs are likely to leave large parts of the memory untouched for
long periods. The best software memory diagnostic would probably be
one that does both regular reads and writes and also uses the DMA.

I have used both memtest and MS memory tester:

to find various ram problems in the past.
