Overclocking Duron 1.2GHz

Hi, I never overclocked a PC but I know a lot about it. I know about the
FSB, multipliers, all that, cooling, voltage, ... But I would like to hear
some experiences and advices about how to OC a Duron. Also what is the
problem I have when I put FSB to 133MHz (by a jumper on MoBo)

I am interested in OCing Duron 1.2GHz(100*12.0). Since I can not change
multiplier of the processor on my mainboard, I would like to overclock by
upping the FSB from 100MHz to 133MHz. That would make nice 1.6GHz. . I
will first write my configuration (I'll try to put it in as many details as
possible) and then I will have some questions for you.

Configuration:
AMD Duron 1.2GHz (i don't know any of the numbers on my processor, if you
need them, i will open the case and post them later)

Matsonic MS8137C (yes, very cheap mainboard, but i had a very tight budget).
Mainboard has a jumper for changing the FSB from 100MHz to 133MHz, it is Via
KT266 chipset, has a 2 DDR and 2 SDR ram places (dont know the word ).
Doesn't have multiplier jumpers, ... I upgraded the bios maybe half a year
ago.

Cooler is Thermaltake, i dont remember the name but it says that it can cool
processors to 2400+. I have one problem with cooling, my case is pretty
small and relativly old so my power supply is right in front of the
processor and cooler. Distance from PS to cooler is maybe 1cm, maybe a
little more so I think that the cooler can't pull in the air normally, is
that a problem?. I have one PCI cooler that is blowing the air from the
case. Idle tempeture is 51?C, under load is no higher than 60C because I
have autoshutdown if temperature exceeds 60C.

Graphic card is Manli GeForce 4 MX440 with AGP 8x (runs on AGP 4x, MoBo only
AGP 4x).

Monitor is Phillips 104E (ancient almost)

HD Seagate Barracuda 7200.7 80GB

PS: Some cheap PS, 200 or 220W

OS: Windows XP

Hmm, I think thats all about configuration.

OC try: I tried to OC my PC by upping the FSB. This is what I did. First I
shutdown the computer and then I opened the case and put the jumper in
position for FSB of 133MHz, then I tried to start my computer, the computer
starts normally, everything sounds normal but the screen wont turn on, it
just stands in standby like there is no signal from the graphic card. I then
thought maybe I need to up the voltage, I set +0.05 V (to 1.8V) and it was
all the same, then to 0.1V (1.85V), the same thing. I thought maybe the PS
isn't strong enough so I disconnected CDrom drive, I took out all the cards
but graphic, even the PCI cooler. Then I started the PC and the same,
computer starts to boot, but the screen wont turn. What could be the
problem?

Questions:

51C idle for a Duron 1.2GHz, is that high?

Is it a problem if my PS is in front of processor cooler (1cm distance)

Is it possible to up the multiplier? I am prepared to work on processor
(connecting bridges, ...)

What is the best way to OC this system?

Would it run on 12x133?

Any advices are welcome.

Thanks to all

Yes, also my memory is 2X128MB DDR ram, one stick is DDR266, other DDR333,
that should work on 133MHz?

As long as you have the ram bus set to 133Mhz, it should. But for tesing
the overclocking of the Duron I'd pull the slower module out just in case
your board/bios tries running the ram bus higher than 133MHz when
adjusting FSB.

your fsb will run fine at 133Mhz with those memory modules.

The cpu won't run at 12x133 (1600MHz) without a lot of voltage and a lot
of luck.

If you want to run with a FSB of 133, then you'll have to lower the
multiplier. First, you'll have to unlock the cpu by closing the L1
bridges, then you can use this to change the multiplier.

10x133 might work. 13x100 might work. You may need to raise vcore. It all
depends on how good your cpu core is. Don't look anywhere close to 1600Mhz
though. It probably won't go that high. If I were you I'd start at 14x100
with max vcore (1.85v) and go from there. Well, actually I wouldn't even
mess with it. The gain isn't going to be worth the effort IMO. Better off
just replacing the cpu with a Tbred B core XP.

Cooler is Thermaltake, i dont remember the name but it says that it can cool
processors to 2400+. I have one problem with cooling, my case is pretty
small and relativly old so my power supply is right in front of the

case. Idle tempeture is 51?C, under load is no higher than 60C because I
have autoshutdown if temperature exceeds 60C.

This is also a major problem. Buy a new cheap ass case and PS for about
$20. Or figure out some way to move the PSU some. I'd also replace the
cpu cooler if you change cpu's. An $8 TR2-M1 will work with any AMD cpu
just fine. Assuming you move the PSU or get a new case.

OS: Windows XP

While overclocking, boot with a memtest floppy or cdrom until you are sure
your system is stable. Otherwise you may corrupt your HD data.

51C idle for a Duron 1.2GHz, is that high?

Very much so.

Is it a problem if my PS is in front of processor cooler (1cm distance)

Well that, and maybe case ventilation, and maybe the CPU cooler, or all.

Is it possible to up the multiplier? I am prepared to work on processor
(connecting bridges, ...)

Sure, but you don't want to do this until you know what you need to set it
at. Use the pinmod, it's much easier.

Your response was very helpful, I have some new questions

If I put my voltage higher, does that affect other cards or drives in the
system? Or is the voltage that I choose in BIOS or by cutting and connecting
bridges just for the CPU?

If I cut my bridges, is it important that any connection between parts of
bridges is lost?

Can you tell me anything about my overclock try, I think it should atleast
give a signal to the monitor so I would see it is starting, then it would
shutdown or similar.

You're reaching for the sky there. There's not much chance that you CPU will
go as high as 1.6GHz, not much at all. Almost none. Miniscule even. Next to
no chance. ;-)

Buy an Applebred Duron, they're cheap.

Just the cpu voltage if you only adjust vcore.

of bridges is lost?

Sorry, I don't understand this one.

If it won't post, you get no screen. If it works, you do.

Your cpu won't run that fast. If you can get 1400Mhz out of that cpu,
consider it good.

Well, I'll try to explain what I mean (im not a native english speaker so
maybe in english it doesn't mean what I meant )). If I am going to change
multiplier of the CPU by connecting and disconnecting bridges, do I need
when I cut the connection between the parts of bridge (or bridges), is it
necessery to remove any connection between the parts? Or just most of it.
Some more explanation , lets say a connection is 100 lines, do I need to
cut all 100 or just most of it (lets say 90 or 95).

I was asking why doesn't it turn on the screen? By your response I guess
that CPU probably can't send the signal because it is running to high.

The monitor isnt coming on because at the speed you have the cpu set at its
failing and isnt working, as said before the multiplier of your cpu is "12"
and running the fsb at 133 is trying to making the cpu work at 1600mhz and
its not going to have it. Lower your fsb to 110 and see if it works. As
said by Wes you will be very very very lucky if you get even 1400mhz 12x116
fsb.
