It looks like your motherboard can support up to 4Gigs, so you should be able to go with the 2 gig kit you were looking at to begin with. That way both sets will be running in dual channel.
Nope, because Windows Media Center is only limited to 2GB the rest is a waste, as discovered in previous posts. So I am just looking at that 1GB ram slot or do I need to have x2 512mb so it runs in dual or something? Wich is best?
The new PC2-6400 RAM will automatically slow down to match the PC2-4100 RAM, so it's a waste of money. The only solution would be to overclock the old RAM (ie, make all sticks run at PC2-6400 speed), but I doubt it will overclock that far.
You'll have to get PC2-4100 RAM if you want to be on the safe side.
How about that, is that the best option I can go for. I benefit from the dual channel, I only go to the maxium my PC can support wich is 2GB, and it's specs is pretty near the one currently in my pc now. Will it overclock it's self to the 4100?
That RAM ill be fine. PC2-4100, 4200 and 4300 are pretty much the same thing; they're designed to function at 533Mhz (DDR). The actual number differs from manufacturer to manufacturer.
It does seem to be your best option. I'd go for it. You'll see a remarkable increase in performance with 2GB.
