One thing that I have learned about fsb overclocking is that the cpu does make a difference. I started out with a T-Bird 900 and I could only get the fsb to 104 with it. It would go to 1200 with the bus at 100 and the multiplier at 12 though. I gave that one to my son and bought a T-Bird 1200 and this one will go to 113 fsb. I run it at 12.5x112 with my ram maxed out. I am using the same setup with the 1200 that I used with the 900 so it has to be the cpu. Same ram, video card, mobo, bios, cooling, etc.. In the past I had always thought that the fsb limits were due to the chipset on the mobo, but now I know different. The chipset does make a difference comparing a KT7A-Raid to a KT7-Raid for sure. I think the people who can get the high fsb overclocks have good ram for one and also good processors. The people who cant that have good ram probably have a processor like my 900 that just will not overclock that much with the fsb. I dont think there would be a large enough gain in performance for me to step up to the KT7A-Raid mobo right now with my current setup so I am going to try and hold out until some newer technology hits the streets.
