He is getting both rated at 800Mhz speed. So there would not be lowest gets dominance.
Though if I am not incorrect the total population of the DIMMS would be:
DIMM 0: 2GB Kingston
DIMM 1: 2GB Kingston
DIMM 2: 2GB Nanya
DIMM 3: 4GB New Company
This way you will loose the dual channel architecture cause all DIMMs are not of equal density.
He won't loose dual channel even if he don't has same density ram sticks .
@mailme.manju, yes. the ram sticks should be in even number & should be of equal capacity irrespective of clockspeed.
Well, it depends on chipset.
OPs mobo has G43 chipset which supports Flex Memory Technology so he can use memory modules with different size/capacity and still remain in dual channel mode.
no problem provided your mobo has 4 slots. but you can get g.skill, adata from here too. ask for a mushkin or patriot if you want from outside
I think he should bring Crucial Ballistix
