I hear that duel channel really isnt much better than single

[little_scrapper]

Is it true that running memory in duel channel mode only give you a very small performance increase? I was always underthe impression that deul channel mode gave good performance increases. Someone please fill me and the rest of us noobs in.

Dual-channel mode doubles memory throughput, and is why relatively slow memory (e.g. DDR2-533) can keep up with a C2D's effective 1066MHz FSB. If your software app is limited by memory bandwidth, this will help a lot. If it isn't, it won't.
Typically this is most helpful in apps that process a lot of data into/out of memory (*not* the hard disk). Photoshop is one such app.
