How does intels multiplier work?

Hi
How does intels multiplier work?
Is there any way to unlock it?
Do they use a simular way to lock there cpu´s as AMD?

All info is helpful.

Thanks from a newborn overclocker.

All Intel's Pentium 3 chips are locked, and cannot be unlocked. Therefore they are overclocking by raising the front side bus on your motherboard.

Hi Snowpatrol
I have a C2 566@850Mhz (waiting for pc133 ram)
100mhzfsb*8.5 GoldenOrb(26-43C)

But does intel lock it?

Sorry forgot how.

But how do they lock there chips?

To the best of our knowledge, it's on the die itself, or at least inside the final processore core. Nobody's been able to crack it yet. Why bother, though, since they overclock so beautifully with FSB manipulation.

Hi Viper GTS
I´m whit you on the fsb.

Ok so it´s in the core but does it not have to send out the multiplier setting to the motherboard as the AMD duron?

To answer your question, the Intel chip does not send the multiplier to the chipset. Intel uses internal fusable links, which are 'blown' at the factory, to set the multiplier.

I've heard industry talk about Intel wanting to lock the clock speeds next, in addition to the already locked multiplier. Any comment on this?

I can't count how many times the Intel multiplier question has been asked. I can get really sick of it, especially when people don't believe me when I say you can't get around it.

I've studied pics of P!!!'s that are online and also my own C!!. I am pretty sure that Intel uses simple micro-bridges on the FC-PGA, just like the Durons/Thunderbirds. If only I had a high-intensity laser to slice and dice the bridges for a test. 🙂

I seriuosly dought that Intel will go to the trouble of Locking the FSB. What do they have to gain ?? the reason they locked the multiplier was to stop remarkers ripping the public off. When it comes right down to it the Athlon is locked too just not as cleverly done( this maybe to allow its users a way to do it and relieve them of the warranty in the process) But still it has to be physically modified to unlock the multiplier so I call that locked. The true unlocked processors were the days when you change the jumpers on the M/B and Bam the overclock was done. If you ask me the FSB overclock has more bennies anyway's as in more banwidth.

Yeah... increase fsb 🙂 dont worry so much about the clock lock, although I wouldnt mind having that option too.... 🙂

Thanks to all.

Good luck and no problem dude.
