Piii-s

[DDR-PIII]

Whats the difference betwen the P-III, P-IIIEB and PIII-S ?

 

[D2DM]

PIII name is used for the following..

Coppermine core chips from 450mhz upto 1100mhz with 256kb L2. (briefly there also was a 1133..)

Where - EB means it is a coppermine core cpu with a 133mhz front speed bus (and 256kb L2 as all coppermine P3's have).

Also PIII name is used for Tualatins with 256kb L2 cache and 133mhz FSB. This kind of P3 is not for SMP.



PIII-S means a PIII with Tualatin core and 512kb L2 (full speed)
This kind of P3 is for SMP.
SMP = dual (or more) cpu systems.

The main difference is that cumine and Tualatins differ in pin function layout and in operating voltage.

 

[DDR-PIII]

PIII-S means a PIII with Tualatin core and 512kb L2 (full speed)
This kind of P3 is for SMP.
SMP = dual (or more) cpu systems.

But you can just use it as one right ?

 

[D2DM]

yes it can run solo.

Seem to oc good to..

check the cpu database for:
Pentium III 1260/133 512K Results....

 

[DDR-PIII]

Total Entries in Database for Pentium III 1260/133 512K - 7
Average overclocked speed - 1600 Mhz

I think if one tried they could get the PIII tualtin 256k chip to go smp as also the cel-t. So far few to none have tried.

i2fast4u had dual celly tualatins running on a modified Powerleap adapter....

 

[TASOS]

PIII name is used for the following..

Coppermine core chips from 450mhz upto 1100mhz with 256kb L2. (briefly there also was a 1133..)

A small correction here...
The coppermine core started from the :
500E (100mhz) and 533EB (133mhz)

 

[D2DM]

ah yes.. thx
I shouldve stayed with my first entry/thought

P3-450 is the Katmai core with 512kb L2 at half speed.



Btw. DDR-PIII if you're thinking about a 256kb L2 PIII look at the Celeron 1.0a..

With no trouble at all it can be turned into a virtual PIII 1333..
and it's cheaper because you have the same chip but don't pay for the "PIII" name/image.

Yep, they made those Katmai cored PIII's up through 600MHz though, as well as making the CUmines starting at 500MHz.

I'd recommend the Tually Celeron 1.0A or 1.1A as well. Those things can fly, even if you need a Powerleap to do it.
