Simple Question --- plz read

Hey I was wondering if FSB overclocks dont go as high as multiplier overclocks
I have my duron 850 at 10x100
and it has problems going 7.5x133.
is there anything i can do because i really like my fsb at 133, and maybe higher :)
maybe even 6.5x154! but thats just a wish hehe
thx in advance

I actually had the reverse happening, I could get the FSB up to 150 but then my RAM started flaking out, but to get the multiplier to 10+ I had to up the VCore to 1.85 whereas I could have it at 9 x 145 @ 1.70V

basically:
10 x 133 @ 1.80V or
9 x 145 @ 1.70V

Though thats not what I'm running at now anyway... ;-)

sometimes motherboards and cpus don't like to run at a lower multi. than the default and may be what is happening here.

Assuming that you have a good hsf and cooling, not to mention PC 133 RAM have you tried upping the voltage of the CPU ?
To run my Duron 800 @ 1050 requires me to use 1.85 v

So, what we are saying here is that it doesn't matter how you get to the higher speed, the CPU still considers it the same and requires a higher voltage.
And which method would be better for the CPU, or does it really matter??

HAPPY 4th of July everyone !!!

Yeah my Vcore voltage is at 1.85, the max for my motherboard, unless there is some mod out there, im not too sure i feel comfortable doing those anyway.
I'm running at 7x143 right now!
My temps are 46 C full load Prime95 running all night. But thats with all 4 of my case fans running, if i turn my 2 120's off i think my temps shoot up to about 50-52 and I'm comfortable with this.
Ya think If i got rid of the stock fan on the northbridge and maybe got a blorb or something i could get a higher FSB?

The ideal solution when overclocking is a fast as possible FSB as this also increases the speed of your cards and thus gives a greater overall performance.

Well, I can agree to a point. It is my understanding that there are issues with some expansion cards with regard to the higher buss speeds.
When the FSB gets to 133, the divisor switches to 4 instead of 3 and the PCI buss starts out at about 34 again.
But aside from that, the temps seem to go up when the CPU speed increases, regardless of the method used.
What I thought would happen is that since I could get the speed to the same point using a lower multiplier AND a lower Vcore, the temps would stay down.
I must of missed that day in class because I can't get it to work that way!!

yes there is a voltage mod for the a7v133.....it's somewhere on tomshardware.com also, it's the same thing for a a7v, at least that's waht i think,....corrrect me if i m wrong
