I've been really curious about this for a long time. havne't found much (ok anything) on the net of why dual channel is faster (searched google, etc). Anyone know?

I guess next time I shouldn't assume that programming knowledge = hardware knowledge next time.. and you don't go assuming the opposite.. because i'm proof of that part...

are you saying because I'm a programmer I dno't know my hardware? I fix, build, maintain computers all the time. I was just trying to learn a little more.

right.. well since dual channel has been out for what.. 2 years? and the fact that you "fix,build and maintain computers all the time" that you would know..

but like I said.. we all have our specialties...

I know dual channel was faster, but I didn't know the specific details of it. and bTW thank you Cik for providing them. alot of people know about dual channel being faster, without knowing the exact details behidn how it works

Heck, I'm the same way. I didn't know the specifics behind Dual Channel either. :P

i dont know much about dual channel but i do know that its like 2 streams of data being piped to mem controllor and then to cpu at a time

128 bits (dual channel) instead of 64 bits (single channel)

in theory, it is suppose to double the performance
but of course in real life, there are too many bottlenecks for dual channel to become truely effective

its still a nice thing to have as it does increase the performance by maybe 10~30% when you have low amount of memory

but from what ive seen in benchmarks, when you get up to like 1GB, dual channel isnt really effective anymore as compared to 1GB single channel

btw
3 sticks of ram works as well
as long as each channel has same amount of ram

that means for example bank 0 (channel 1), has 512mb of ram
bank 1, bank 2 (channel 2) have 256mb of ram in each bank on this channel so 512mb total in this channel

then voila
dual channel
its what i have my system setup in now
