This is probably a question that would have been better asked in the "memory" forum section. They deal with memory questions far more than this Cpu forum section does. It is generally not suggested to mix ram brands and most often it is suggested to never mix ram speeds.

1. Not much DDR667 ram would run at DDR800 speeds. Generally never without a voltage increase.

2. You need to remove the 1 gig stick and see if the DDR800 stick will run when placed in the slot where the DDR667 was used. If it will not work then seems the DDR800 maybe bad.

3. It is always recommended to clear the CmOs after changing some hardware component like ram in order to have the bios take a hard look at the newer hardware.
