question re: kt133 overclocking/ 1.85v too much for an athlon?

i'm curious to know if anyone has had any success in overclocking their processor on the kt133 chipset by dropping back the multiplier and raising the fsb. i've heard that the kt133 motherboards are notorious for not being able to hit high fsb speeds. i was thinking of unlocking my 1gig and changing the settings to 133x7.5. before i do that though, i'm curious to know if anyone else is doing that.

also, is the kt133a any better at overclocking?
 
I have an Asus KT133a, and it's stable at 146 fsb with highest memory timings, and is stable at 150 fsb with "system performance" set to "normal". From what I've read, KT133 chipset is lucky to do 110 fsb.
 
i have an asus a7v with the kt133 chipset and i never got the fsb to run very high (102mhz but if i had a better psu maybe 105 to 112 which seems to be the highest)
the higher you make the fsb the more unstable you system is
basically the kt133a chipset is much better
you will never get a 133fsb with the kt133
your best bet is to just unlock your cpu and put the clock mult higher and leave the fsb alone
 
thanks for the input guys. i unlocked the processor and sure enough, i could not get it to run at 133mhz. i did post at 117mhz, but it froze in windows. the nice thing about the asus a7v is that if you go too high in overclocking it will revert back to the standard settings in the bios so you don't have to clear the cmos or anything. the epox 8kha+ is a pain that way. i love this motherboard though.

i did get it to run stable at 1200 as long as i have the vcore up to 1.85 from 1.75. is anyone else doing this? i know it won't fry my cpu or anything as i have a nice big taisol heatsink on it, but will it shorten the life of the cpu too much?

opinions?
 
I did the voltage mod to my board and ran mine at up to 2.0v
wouldn't suggest going any higher than that though
i ran mine at 1.25ghz but that was basically cause i needed a better psu the 5v rail was droppin a 300watter just didn't work
search around on google.com you'll find several voltage mod howto's for the a7v but you'll need a really small soldering iron and a steady hand, much light too,
well have fun again
