Here in desparation !

I don't mean you have to be desperate to be here, I mean that I am desperate for an answer I'm hoping someone here can give me.

I heard that overclocking a Duron was easy, with fairly major results, so off I went and spent hours on the net reading everything I could get on the matter. Unfortunately every article I read revolved around a BIOS with the ability to set the FSB and multiplier in it (and usually an A-Bit mobo). My problem is that mine doesn't. Here's what I've got, and I want to know 1) if it is possible to overclock and 2) how to do it (I'm guessing it'll involve more than a 2HB pencil)

AMD Duron 700MHz
Lex BN780 KT-133 mobo
Pheonix Award Bios ver 663ASA14
250W PSU
Various flavours of RAM, ie both 100 & 133
Chunky heatsink + fan
Sufficient case cooling

I really would like a nice positive responce like 'Bridge the CPU to the CD-ROM lens with a crowbar, then tie a piece of string round your big toe and sing Humpty Dumpty backwards 3 times.', but if it can't be done, I'm a big boy and can take the truth.

Thanks, Sensillium

First of all, Welcome to the Forums !!! :D

Then, concerning your motherboard, it's a KT133, which only supports about 112MHz of FSB (front-side Bus). so you'll need to unlock your CPU (connect all the L1 bridges on the CPU). You'll then have to look in your motherboard manual see if there is any jumper for multiplier or FSB settings. if not, look on your mobo itself, and try to find a little diagram that shows which jumpers do what (as I saw a picture of your mobo, and the has jumpers a little everywhere, so you need to find the correct ones if your mobo supports overclocking). After you unlocked and found the jumpers for controling the VCore, the FSB and the Multiplier, try different combinations. just don't get crazy with the vcore, as it controles the voltage that goes to your CPU. And be sure to have sufficient cooling, as OCing increases the temps. Just be sure that the settings you put are stable and everything. If instability comes, just increase a little the vcore, see if it does any good. Watch out, as increasing the vcore increases temperature.

BTW, if you haven't done so already, I suggest you go and read the beginners guides on the front page, it tells alot of what to do, and how to do it, for being sure everything is allright.

Hope this helps, if you have anymore questions, just post them, we'll all do our best to help you solve them ! :D Keep us informed

I'm sorry :eek: I forgot to tell you that my mobo is virtually jumperless as regards the black plastic chunks, but as for the info I am greatful, and shall be drawing little lines in but a short while :burn: !

Thanks again, If this works there shall be big celebrating :beer:.

I have studied my mobo for hours (well about 1/2 :o ) and can find no sign of any FSB or Multiplyer jumpers anywhere on it, not a bean! A link to a pic of my mobo and directions overlayed would be good, though somehow scarce I think :rolleyes: .

here's the pic I found, if you look a little everywhere you can see some black spots that I belived were jumpers : http://www.linden-computech.com/images/larg/bn780.jpg

If there isn't anything, you could try using software OCing, check this thread : http://forums.overclockers.ws/vb/showthread.php?s=&threadid=51669

if not, then I don't know what you should or could do ...

looks like there may be some jumpers next to the ide connector.

if not looks like you may be in some hurt.

if at all possible try to aquire on on the newish esc or shuttle boards.
ive heard good things and they arent ovrely expensive.
