kt7e+duron750=no overclock?

[Whoelse]

it seems like i really don't have any luck. a bought a kt7e and duron 750. of course i wanted to overclock the duron at 750 to about 1g or more. preferably more. :) i colored the pins (about 6 times, have stopped counting). the result is that now i can UNDERclock it, but not oc it. wheres the problem? could it be that mobo doesn't support durons over 800 (i think it states in the manual that supports durons up to 800mhz). i really don't now anymore.
although it seems that bios might be the cause. when i oc it, it reboots and when it supposed to show the result, i get a note: award boot block and checksum error. i cleared the cmos, i don't have any jumpers or whatever. i think that either is the mobo or the salesman gave me a crappy duron (will check if it really is a duron 750).
and one last thing. the other day when i was moving max payne from one partition to another (it was veeeery slow, don't know why), i ran wcpuid. what suprised me the most was the speed of my processor. it was just under 800mhz. this was very odd, so i ran the wcpuid a few more times. so i got reall interesting results. duron was oc a few times and one time even underclocked.
maybe this is a case for the x-files? :)
can anyone please help me? i'll get watercooling in near future, so i would like to oc my duron. the only thing that stands in my way is that i cannot oc the damn thing.

!?!?

Have you tried upping the fsb?

the kt7e will do 133.

i don't think so. either you are mistaken or my mobo really sucks. this motherboard doesn't support 133 fsb (266 ddr). only the new ones do. i think. anyways, my motherboard doesn't suport fsb up to 133 (it won't even work on 106mhz).

The KT7e does not 'officially' support a 133 mhz FSB and likewise the Duron does not 'officially' support it either although both can usually obtain it quite easily, however to achieve this will very likely depend upon the memory you have.

When you state that you "colored the pins (about 6 times, have stopped counting)." what do you mean, are you refering to the CPU bridges and if so did you ONLY join the L1 bridges and if so with what?

[Whoelse]

okay. it goes something like this:
i colored the pins, but it didn't work. so i erased it and colored it again. 6 times, because i couldn't overclock nor underclock duron (some clock frequencies worked, but only the ones lower than 750mhz). i did that with ordinary hb pencil. i cleaned the bridges (i colored the l1 bridges only) with alcohol.
these few days i had problems with my computer. i got stop screens in win 2k pro and blue screens in win98. i thought that was modems fault (it's a 56k motorola modem, that doesn't work as it should). so i blamed the modem for consistent crashes. i managed to log on to the net, but only for few minutes. than i got errors from iexplorer and stop screens (i was mostly in win 2k pro). the hard drive shut down and there were errors in ntoskrln, powervr.sys, win32.sys (i think) etc.
i haven't had the time to reinstall the windows and fix the problems, 'cause i had and i still have some exams to pass.
the other day i underclocked the duron to 600 (6x100) and it looks like it works perfectly fine (the system doesn't crash, games work, i can get to the net).
so now i really don't know what is the cause of this. when i will get some time to spare i'll try to fix the problems, until then i can only hope that duron will overclok when i get water cooling.
so many problems, for what? previously i had a celeron 2 600 oc'ed to 900 rock stable with goldenorb and it would overclock even higher with water cooling.
the one thing i know for sure is that if i will continue to have problems with this piece of #### i'll throw it all away and smash it a few times with jackhammer. and then maybe, just maybe the whole thing will just once work as it should.

i have a kt7e and a duron as well ... i have some probz with it as well but im not sure if they are mobo related
i tried unlocking my duron but it didnt work well :(
but then i oced my fsb to 112 ... ROCK STABLE at nice temps
the only prob im now facing is that it wont go over 112 ... but im still checking into that
i think my sound card is the little ******* here ... but im testing my system and im going to find out ... cya
hope ive helped you

my fsb works fine oc'ed to 110, probably could get higher, but i have two diferent (from another manufacturer) 128mb rams.
the problem i have isn't fsb related, because my system isn't stable at 750 mhz (7.5x100), which is the default speed of my processor. neither i can overclock it via changing the multiplier (i can, but system hang's up). my goal is around 1ghz (with water cooling even higher), but clearly i can't overclock the duron due to some unknown problems. if i only knew what is a boot block error. i get this message every time i oc it over 750.
i have still one exam to pass and when i'm thru with that, i'll get down to the bottom of this mess. 'till then i can only run my sytem underclocked, 'cause, like i said, the duron won't even work on default speed at 750.
i'll get water cooling up and running in about 2 weeks, i still have to get some parts and buy some stuff. if i don't solve this problem by the time i get all the things needed, i'll take it all back to the store and buy a good old celeron :).

First of all, Welcome to the forums!

If you guys are getting to 110/112MHz FSB and hitting a "wall" it's probably the PCI bus. At that FSB you are running the PCI bus at 36.6 / 37.3MHz (1/3 divisor). You may be reaching the limits of the nics, video card etc. If your chipset will support it you should go to 133MHz FSB, at 133MHz the PCI bus is running at the spec of 33MHz (1/4 divisor), thereby eliminating potential problems with the PCI / AGP cards.

If you are going to run the PCI bus at an elevated level, you may as well run a FSB of 140 yielding a PCI bus of 35, still closer to spec than running the FSB at 110. But at that speed, expect problems from your USB devises.

My $.02

Good Luck!

Via released a patch for USB and FSB > 140Mhz.

I closed my L1 bridge with silver ink on TB 850 and got only
6.5 / 8 / 8.5 multiplier avalaible
7 / 7.5 / 9 / 9.5 doesn't work.
So my system is running stable with 148 FSB and will try FSB > 150Mhz.
Did you try 6*133 / 6.5*133 ? I can't imagine an Abit mobo that can't do more than 100 FSB.
Do you have FSB plus option in Soft Switch menu ?
