What's the definiton of a multiplier locked processor?

[Biggs]

Can do lower than default multipliers but can't do higher than default multipliers. Is this considered an "unlocked" processor?

We can't do anything but operate at the multiplier it design to run at, thats a locked processor. An unlocked processor allows the user to choose the multiplier.

I have a 2.5 x 133 = PII-233@333 default is 3.5 x 66. If I set the multiplier to anything higher than the 3.5 default, the system refuses to boot. Theoretically, I should be able to do 4 x 66 = 264, 4 x 83 = 332, or 4.5 x 66 = 297 since I'm doing 333 right now on a 133 FSB. So now, is this processor I got unlocked or locked?

It is unlocked or you would not be able to change the multiplier at all.

Thats very interesting, it sounds like unlocked, but unlocked processors should be able to allow you to choose multipliers above the default.

Someone told me *all* Klamath processors are unlocked. Any truth to this?

 

[LXi]

Not all, but a batch of them is unlocked.

Just be careful or you'll end up with a P3-133.

Intel has produced three types of processors.

The first one is the unlocked type, where the user can select any mutliplier. Most Pentiums, all Pentium Pros, some Pentium IIs (very few) and Engineering Samples are unlocked.

The second type, covering late Pentium MMXs and Klamath Pentium IIs, were what is known as clock limited. Any mutliplier could be selected, up to its default multiplier, but not beyond. A clock limited Pentium II 300 could use any multiplier from 2.0 up to and including 4.5, but not 5.0 When set to 5.0, it would drop back to 2.0.

The third type, introduced with the Celeron processor, involves what is known as a clock lock where all mutlipliers except for the default are ignored. Only one multiplier can be used. All presently produced Intel Processors are of this type.

 

ROFLMAO!
Nice PIII you have there Windogg
