Would suggest for anyone 400FSB * 9 which is 3600mhz and 1:1 ratio for 800mhz ram with tight timings.. This exact setup really flies and it's usually not worth going any farther. I'm trying to get 450FSB *8 .5 just so i can run my ram higher and it's complaining :/
That makes sense. My q6600 can get to 3.3ghz (9 x 370) but it needs 1.31v in bios and memory voltage must be raised o 2.05. I chose to go with 400fsb x 8 (3.2ghz), 1:1 ratio, 1.2875v in bios and 1.95v for ram (4,4,4,12 timings).
It passed OCCT 30' stress test with core 1, 2, 3, 4 highest at 57, 59, 56, 56C respectively. Room temperature is set @ 76F. My application works floawlessly for hours!
