.my question is this that to what extent can i overclock a duron 1.3 ghz and 1.2 ghz WITHOUT THE UNLOCKED MULTIPLIER LOCK,i've heard AMD has locked it's processor multiplier on the new duron.My last question which athlon xp can be overclocked the most and from what price does amd's lowest xp start from [retail edition].PLZ HELP

You can probably overclock the FSB, but personally I can't get my FSB above 105 without the whole system locking up :( and even if you can Ocing the FSB more than about 10% doesn't usually work because of the strain it puts on the whole system. Rather than unlocking my multiplier (I have an older duron) I just turned to OCing my gfx card, and got a 30% performance boost from just that :D

Yes they are locked....there are several articles out that give good instructions on how to unlock em. On the older models it was a s simple as using a graphite pencil. The newere models have some laser cuts and locks that must be bypassed before you can use conductive material to do it.

Hmms, i've got a duron 1.2Ghz (morgon ofcourse) that has been unlocked with the old penciltrick :) no laser-cuttings here :)

Though there are 5 "bridges" instead of just 4 to connect...

The motherboard and memory are the most important in overclocking the FSB.

However the latest Durons (>1G) are not great overclockers as they reach the limits of their manufacturing process.

Same for the XP's.

For the 1.3G Duron (13x100) I wouldn't expect anything higher than 1400.

The best thing you should do with the duron is unlock it (pencil trick works fine) take the multiplier down and set it to work to 266FSB at the same MHz.

So the 13x100, could be run at 10x133. As long as your motherboard/RAM support FSB266 (for XPs) your are still within specification (apart from the CPU) and you are not overclocking as such but you get a nice 33% increase in RAM speed (and general interface speed).

Thats a good point. But on my duron sys. I have the 1gig at 10x 100mhz fsb with 133mhz ram timeings. How would it effect mine. Don't I already have the advantage you speak of. Maybe his board is the same! Just curious.:D

Yes, async is the default mode to run PC133 RAM with a 200Mhz based processor (so the RAM runs asynchronally with the FSB, former at 133, later at 100). This is within spec and gives the max performance within spec.

However the CPU only has a 100Mhz defined bandwidth available to talk to all the other hardware. Getting it to 133 (and thus 266Mhz, which is out of spec for the duron) is a 33% increase in bandwidth, that really shows nicely.

So your 10x100 CPU can run at 7.5x133 and while the Mhz are the same (no need for extra cooling/voltage etc) you get a nice performance boost.

In such case you run FSB and RAM synchronously.
