Compatiblity issue, you may try to tweak the voltage in bios, may or
may not help.
I would rather run 2x1 gig of ram in dual mode than 3 gigs in single mode.
Filling all the RAM slots on the Mobo is not advised.
Try the new RAM by itself to determine if the RAM is good.
Running the 2X1 and the 2X512 should still be Dual Channel.
I didnt catch the 2x512, your right, but still doubtful it will work mixing
the brands..Even if same brand, and type its a crap shoot whether it
will work or not in dual mode..
