Just went through the entire thread, great read. Wanted to ask this without starting a new thread. I think I already know the answer but I would like to get a few recommendations from phenomII users with ddr2. My ram is advertised as 1066mhz 555-15. If i run my NB 2400-2600 would I benefit a lot by running 800mhz 444-10. Would you suggest going any lower on timings if I can get it stable? I'm not home right now and I forgot how low my bios will let me set the timings at 800mhz. Also, how important is bank cycle time (tRC)? And what should I set it to? Thanks.
