Dual channel memory and max cpu fsb

Missed the bottom question... DDR means double data rate, so you set the ram to 333 in bios, it really runs at 666. Dual channel is something different, and deals with bandwidth, not speed per se.

If your going to keep a 1:1 ratio, you will need more than a FSB of 666mhz in order to go over your rams rated speed. That means you will literally need to double your overclock, before the ram becomes the limiting factor. I don't see that happening

according to the thread i posted in the beginning, for ddr3 you take the mhz its rated at and divide by 4(divide by 2 for ddr2), mine is 1333. so divide that by 4 and I get 333. he is very specific when he says not to exceed that number for your ram unless you are trying to overclock it. This leads me to believe that ddr3 memory is supposed to be fsb x 4 = ram in mhz.

Not trying to be a pain in the ass, really trying to understand. cpu-z and everest both have me at 1:2 fsb ram so i'm assuming you are right, just having trouble understanding why.

awesome, thanks! so now I guess I have the options to increase my cpu and/or reduce the clock on my ram and try to reduce its latency timings. just for ultimate clarification, it would be pointless to increase my dram speed as long as my cpu fsb is 333 right.

You can try tightening the timings a bit or try overclocking the ram a little. I wouldn't kill yourself tweaking your ram as long as it's running at or near spec. Real world apps don't show a whole lot of difference with lower and slightly higher ram speeds. But in my opinion, can account for a good majority of system instabilities.
