As per title, I have an old Dell Precision M4300 laptop with 2 identical
sticks of Crucial CT25664AC800 16 FHZ 2GB DDR2 SODIMM PC2 64 RAM.
Running the RAM test from the Ubuntu 16.04 64-bit grub boot option, each
stick passes individually in Slot 1 (under the keyboard), but together
one in each slot they fail, and the PC won't boot with a stick only in
Slot 2, behind a cover on the base of the laptop.

A Google search didn't find much that was useful. Any suggestions as to
what may be wrong?

TIA
I assume that your laptop claims that it will work with
4GB ram?

I once had an issue with a bad bit in the high memory area of
a ram stick. Turned out that the bad section was used for
display frame buffer and memory test didn't test it.
