View Full Version : is there a limit with the multiplier...?

hey the new tutlatin celerons run at 100mhz fsb right? and a 12X multiplier right? so that gives us 1200mhz. if intel is going to create a faster chip will they just raise the multiplier higher? is there a limit to how hight the multipliers can go? or will they have to bump up the fsb speed? and are tulatins socket 370?

I believe they will just bump the FSB up and the newer motherboards will probably have newer functions such as setting your PCI as much as you want etc ..

And yes it is ran as a Socket 370.

well i have a abit vl6 with a max multiplier of 12. so why cant i run the new tulatin?

I believe your motherboard is designed for the chip of P3 and Celeron only and the Tualatin uses more advanced technology thus it won't be compatible with old motherboards.

Unless you get a PowerLeap adapter.

Actually, one of the ICs is different on Tualatin boards. I think it's the voltage regulator. You might check with Pinky or some of the others running those chips. The T chips require a different voltage than P3.

This has already been done. P4 - 400 MHz FSB. If the "newer chips" mentioned meant P3, as I understand it we're near the end of the road for those.

I think we will see a 13x100->1300 mhz Celeron 3.
And maybe even a 14x100 and 15x100.

this shouldn't matter to the mobo because the multiplier is locked. And the mobo settings will be ignored by the cpu.

And.. older 370 boards don't support the Tualatin because of pinlayout differences (and voltage perhaps)..
But the new tualatin capable boards are backwards fcpga 370 compatible I think.
Meaning a Coppermine based cpu will run on it.

how will they be backwards compatible if the pin layout is different?

I guess it could be different pins..

But you can get a Powerleap and hook it up :)

the number of pins are the same and the placement is the same, what the pins do however are completely different....

oh ok thanks ppl

If I'm not mistaken, the Katmai and Coppermine have different pinouts, also. Current boards also support both of these. They just make the boards "smarter". :)

I knew it :P

That's what Abit did with the VH6T, took the standard VH6-II board and made it 'smarter', enough to know what the changed pins could do that weren't being done with the regular P3/celeron coppermine chips... which it also runs way down the scale as well as Tualatins up to 1.53ghz,

Isn't it the voltage regulator IC that was changed? VRM something? I remember looking at some spec sheets a while back, but can't remeber if that was all.

They changed the regulation to .025V increments, which makes for smaller overall voltage increases over default... but this is primarily due to the efficiency of these chips. To do this they needed more pins to be used for voltage regulation, so instead of the 3 pins the original P3/celeron coppermines had, they've assigned 5 pins on the tualatin to set voltage values since there are more possibilities/steps of voltage that can be made form 1.05-1.825V in .025v increments.

I think I confused myself, I'm going to lay down now until the dizziness goes away :).

Since were gettin into the FSB thing, I gots a question. P4s run at 400 mhz, thats 100mhz QDR. AMDs run at 266 mhz, thats 133 DDR. Does the base FSB degrade performance? Also, would it be possible to integrate QDR technology into AMD's? (that would be sweet, hmm... 133x4=532mhz fsb, thats fast!)

Maybe you should start a thread on this... it's getting quiet in here ;).
