I have a 2 gb kingston ram 800 mhz single channel and i want to buy a new 4gb transcend ram 1333 mhz single channel. What performance will it provide to my desktop.
ok... for dual channel both ram need same speed.. means both ram should run at 1333Mhz or 1600Mhz whatever it is..

also for triple or quad same speed needed...
dual channel will add little performance improvement and everyone will recommend to you for getting dual channel or triple or quad setup...
