dual channel query

to know details about dual channel go here *en.wikipedia.org/wiki/Dual-channel
yes it would make a difference if you had 2*256mb rams but only a slight one
i have tried both 2*512 and single 1 gb sticks.but didnt notice any significant increase in performance.in short no huge performance gains.

hi
what is dual channel memory? i have 1*512 ram, would it have made any difference if it was 2*256? does dual channel speed things up?
nd if i make total ram upto 1gb, will it give a huge performance gain over 512mb? i hav athlon xp 3000+ nd asus a8-nvm....

do u want to try or u need exact answer ?
if u want to try then try it yourself or else
go according to ur motherboard ....
if it says that it support dual channel then u should use two memory sticks of same speed with the motherboard .., as u say that u r using AMD then u should go for Dual-channel architecture DDR/DDR2 SDRAM,
and for better result go for Dual-Channel DDR400,

how to know which RAM module is dual channel capable or not ?

i am getting a
UMAX DDR DIMM 512MB module with 8 chips (U2S12D30TP-5) in a single side and the other side is empty ...

is that dual channel not?

A double sided ram,and a set of ram running in dual channel is 2 diffrent things. It seems that you are confusing them

i am not confusing them , for them i had given the reply correctly ,,

but in my second post i wanted to know that how to know if a RAM module is Dual Channel or not?

RAM modules are not dual channel, its the way you install them on your mobo that makes it dual channel. Basically, there are 2 channels on your mobo (provided your mobo supports dual channel) throught which data is transfered to and fro the processor and the RAM. If you place 2 RAM sticks on 2 different channels you are increasing data transfer thoroughput by double. One analogy to this is 1 lane road and 2 lane road. 1 lane road is similar to single channel mode where only one line of cars can move at one time. In a 2 lane road, 2 lines of cars can move at the same time therby increasing traffic throughput. On a 2 lane road you will reach your office faster, similarly your PC will speed up when on a dual channel mode.
