Dual Channel and Overclocking

[INGlewood78]

I've heard that when you are running in dual channel, its harder to increase ram speed when overclocking. My setup is a 1700+ DL3TC, NF7-S, and Geil pc3500. I can't get the ram past 200mhz. SO i have it at 11 x 200, in sync. Many people have gotten their 1700+ past the 2.2 ghz mark. Do u think this is whats holding me back?

I am unable to run dual channel and get past 190. I can run my 2 sticks of hyperx pc3500 in single channel and get to 215 though. From what I have seen and read, dual channel takes more juice and with my 8RDA+ I would need to do a voltage mod. Not sure if that is the same issue with your set up or not.

But I ran benchmarks on my system with dual channel at 190 and with single at 215. My memory scores are much nicer with 215 so I am not bugged my not running in dual.

Try a single stick and see how high it will go. Make sure you are'nt running your cas levels too aggressive.

I am more concern with performance than a Ghz rating. Therefore, do you think is better for performance if I run in Dual Channel @ cas 2-3-3-6, single channel @ cas 2-2-2-6, or something like 433mhz but with looser timings?

Thats interesting...sites (i.e. Tomshardware) have benchmarked both dual channel and single channel and dual has always been faster...maybe they didnt take into account the fact that you can overclock better in single channel???
