you can try upping the voltage of the ram by 0.05V. I had a stick that threw
errors unless I gave it a bit more. After that the system was stable and none
of the memtesting apps found any errors.

no, not entirely true. There is a problem with Phenoms and DDR2 1066 when for
modules are installed. You can get that configuration stable with an high
quality board and some voltage tricks.

If you have problems at lower speed and 4banks, you have a crappy mainboard.
Maybe increasing voltages a bit (0.05 to 0.1V) will help you. It did for me
with one certain Asrock board.

This is the first I've heard of adjustable voltages. Where/how do you make
the adjustment?

Mine is in the BIOS.
