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

[Calvin Harrigan]

It's very possible that the video card is using the 
remaining/unaccounted memory.
You didn't detail what brand of PC it was, but if it doesn't have a 
dedicated video card, chances are memory is being used for video.
When the  system only had 2GB did you see the full 2 GB?
In 32 bit mode usually less than 3.89GB is available,  but it's all 
hardware dependent.  Some memory space has to be left open for peripherals.

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.
