[ale] how do I test 4 GB or more of RAM

[Brian Mathis]

You can go right to the source and get memtest86+:
    http://www.memtest.org/

I use this on servers with 32G RAM and it's works fine.


P.S. This is not a special Linux kernel; it's a completely separate thing.

I booted the Ubuntu 11.10 alternate 64 bit cd and selected memory test.  The CPU is an AMD Athlon 64 chip.  Apparently, though, the MemTest86+ is running in 32 bit mode.  It's only reporting 3.89 GB being tested.  I need to know how to test all the RAM, although it's unlikely that the last .11 GB has an error when the other didn't.  But, what if I had 8 GB, etc.  I want it all.
