Okay, I keep hearing how everyone wants 1:1T, but with a quad and a x9 or x8 multiplier you're not gonna be getting very high FSB frequencies. Is it better to run 1:1T at the lower speed or some other ratio at a higher speed on the memory? Thanks.
I'm not sure what you mean by 1:1T. It appears that you may be combining 2 different things. 1:1 refers to the ratio of speed between the CPU and the memory controller and seems to be what you are asking about. In a nutshell, NEVER sacrifice CPU speed only to get a faster memory speed. If you are interested in OCing or tinkering, I suggest you find your fastest CPU OC. Then, you can look at getting faster memory speed from that point. Your MOBO/chipset will play heavily into this.
As far as 1T, this is not a critical setting and usually 2T is more stable and allows for more OCing on Intel based systems. 1T is faster in benchmarks but the difference is not detectable to the naked eye in real world usage.
You are absolutely correct, I did have two things combined that should not be. With regards to the ratio, you are saying that if I can push my RAM further than my CPU, I could see performance gains, correct? So, there's no reason to leave it at 1:1 if I can push my RAM further than my CPU.

"SOME" applications will see a benefit from running the memory faster than the CPU but not all. And, I did some testing a while back and it was about a 2%-5% benefit at most, depending on the app. That's why I say do not sacrifice CPU speed in an effort to get more memory speed as the results are not worth losing CPU cycles.
However, if you are a pure benchmark junkie this does not apply.
Okay, I have my Q6600 stable at 356. I'm using Ballistix 6400 which I can push further. With 2.2v I can run it at 445 (4:5) 4-4-4-12. With 1.8v I can run it at 356 (1:1) 4-4-4-12. I haven't tried to tighten either of these timings, but I know I can do either of these. Which would you advise? Thanks.
