I gave you the exact JEDEC specs the 4x 1GB DIMMs need to be, and you
didn't respond to that.  Post the part identification number and density
information located on the sticker on each of the 4 DIMMs.

Either the board has a problem or the DIMMs are the problem. Apparently
the board worked fine for years before you added RAM, correct? That
makes the DIMMs the likely suspect.

I am going to try running sysbench on the memory and see if that
uncovers anything. I know that it is primarily for bench testing but may
uncover something.
Sysbench can't tell you why the BIOS doesn't see all of the RAM.  It
might reveal a timing problem, or bad cells, but such issues won't cause
the main problem you have.

I found memtest86+ in the debian package list. It tests memory before the kernel loads. It only found 2.9GB of memory and didn't find the 4th memory slot on the board. i installed lm-sensors for other reasons and all of a sudden I have the full 4 (3.9 shown) GB of memory. I have no idea why unless lm-sensors effected the reading of SPD info from the memory modules. What ever, I hope the fix holds.

Thanks everyone for your help

Cancel that last message. It's just plain wrong.
