as far as the different brands, in theory yes, though the PC will run at the lower rated ram stick. as far as dual channel is concerned, some motherboards require the ram be installed in sets of 2s, others dont, even if they dont you will lose the dual channel performance boost you would get from using 2 sticks when only using 1 or 3 slots. generally, for best performance, you want an even set of memory sticks, all running at the same voltage, clock speed, and timings. I would recomend finding memory of the same type as the memory installed, and instead of just installing 1 gig, buy 2 sticks of similar model ram. if the OS is 32 bit, it will only recongnize somewhere between 3.25-3.75 gigs of it, but you will get the performance boost from dual channel. either that or finding a 2 x 2 gb set of it, you can pick up 4 gigs of generic ddr2 667 mhz from wally world for around 50 bucks, and since the memory you have is generic to start with, it should still give you a good performance boost.
