Intel multiplier locked

[elec999]

Is it true that all p4 are multiplier locked, can only be overclocked by changing the fsb. Theres no tricks at all.
Thanks

All production P-4 CPU's are indeed multiplier locked. No way to unlock them either. But don't worry, it's not needed. Get a motherboard that allows you to lock the PCI bus and you can O/C the FSB to your heart's content. It really is not a handicap at all. There are a few Engineering Sample (ES) P-4's that have unlocked multiplier, but those are not available to the general public.

I get you now, so instead of runing per say my p4 cpu stock 12x133, I could try 12x200.

I've got a 2.4C that will do 3.5ghz at 295 FSB, and a 3.0C that will do 3.75ghz at 250FSB. Who needs an unlocked multiplier?

Yeah, except there is no desktop P-4 that has default settings of 12X133.

Didn't the P4-M's default to a 12x multi at 133FSB when placed in a desktop board?

 

[batboy]

Oh sure... great... go ahead and prove me wrong.

HAHAHA, love your edit punk

I was using these numbers as an example.

Basically there is no need for multi adjustments with now-a-day hardware because of ram deviders and PCI/AGP locks.

Kinda of a shot to intel's non overclocking plot. Ha.
