I am overclocking my Q9450 on a Gigabyte X38-DQ6 using OCZ's 2x2gb ddr2 PC8000 platinum rams. My CPU seems to have reached it's limit at 3.4 and the motherboard doesn't seem to cross an FSB more than 1800Mhz. So the only way I could run my memory at 1Ghz was to use a 5:6 divider, I tested the setup on prime95 and everything seems to be stable. Am I getting anything out of the higher memory bandwidth rather than running it at 830Mhz?
 
Yes you are. Do some rendering or simple Pi tests and you'll see 5:6 is better/faster than 1:1. That's what I'm doin'.
 
Reading across the web. most of people still recommend 1:1 which leaves me confused as higher memory bandwidth should perform better and reduce any bottlenecks.
 
1:1 can provide better stability in certain situations, but if you can run 5:6, you may as well.
 
I ran prime95 for 7 hours without any issues, with the FSB working at 1680Mhz and the rams running at 1000Mhz @ 5-5-5-15.
