single vs dual channel nforce2

I seem to have hit my limit at 221mhz on the ram, so would running in dual channel give me more performance even though i would likely have a lower overclock? or should i stay at this speed and work on ramping up the cpu? (which i'll need better cooling for. either put my delta on, or buy a watercooling setup, and that's not cheap!)

suggestions anyone?

dual chan gives u a better performance check this link for more info

heres a thread some of us did to compare the differences between single and dual channel as well as different FSB speeds on a nforce2 board http://www.ocforums.com/showthread.php?s=&threadid=267160

so basically the difference is really small and its probably better to go with one overclocked chip than two running at stock. in fact, it looks like the performance gain from running two overclocked chips isnt really worth the price of one.
