Athlon 1.2 Ghz Tbird - CPU/PCI Bus Freq??????

[sammy5gs]

Hey...

I am in the process of o'clocking my Athlon 1.2 Ghz Tbird (A7V333 mobo/Enlight 300W PSU/512 MB PC2700 DDR and have one question.

As I update the CPU/PCI Bus Freq. (starting 103/34 and going upwards) in the Bios, I get Warning Messages during some diagnostics that Sandra runs claims that the AGP/PCI bus is not a)optimal and b) not accurate? I am guessing it is because it is not set at 33 (normal PCI Bus), but am not sure? What potential impact would occur???

Any thoughts? Also, is this the setting that also affects that AGP Bus (mobo supports 4x).

I am unfortunately a noob when it comes to overclocking, but am almost done and just need some final guidance.

Thanks!

you can ignore those messages in sandra (just telling you the pci and agp are out of spec, but thats going to happen if you overclock the fsb)

since you have a 1.2ghz tbird the cpu should be unlocked from the factory

so first thing you should do is use a 133mhz fsb as your baseline (set the multiplier to 9x and the fsb at 133mhz... that will give you 1.2ghz)

from that point you can either increase the fsb some more, or increase the multiplier... for example if leave the fsb at 133mhz you can increase the multiplier to 9.5x (which will give you 9.5x133=1266mhz) or 10x (this will give you 10x133=1333mhz) etc etc.

you can increase the speed until your system becomes unstable (increasing the vcore will help the cpu run at higher speeds and be stable, but it also increases the heat output, so be sure your cpu doesnt get to cold)



but no matter what else you do be sure you at least run 9x133mhz (this isnt an overclock... at this setting your whole system will be in spec and it will perform much better then your current 100mhz fsb)
