answer this simple thing about p3s really fast pleasee

[starcraft_azzkikr]

just wondering if a socket 370 p3 500 chip will run correctly at 66 mhz bus? it's a 100 mhz bus chip. Thanx I'm upgrading an hp. i know about multiplier locks and stuff just need to knowe if it'll run.
Thanx

of course it can, CPUs can work lower and higher. http://sysopt.earthweb.com/forum/smile.gif

my friend ran his slot 1 PIII 500 katmai at 200MHz, hehe, just asked him to do it, and he did

[Eli]

To clarify, it might run. But understand that it would not run at anywhere near 500MHz. If it works at all it would run at 5x66 which gives 333MHz. You might as well try stuffing a cheaper, yet in this system faster, Celeron in there.

[starcraft_azzkikr]

It does have a celeron it in but it's only a 266. well were putting it in there cuz it's the only thing avalible right now.

As long as you're sure about the voltages, and you already have the chip, then by all means give it a shot. If you're buying a new chip, a fast Celeron would be a better bet.

You must check if it can run @ 1.6v
Not just that...if its a Socket board, you MUST make sure that it can accept FCPGA processors. If yes to both, I would suggest getting a new Celeron FCPGA processor at 533 or 566.
If not, I would suggest a Celeron PPGA processor, at 466, 500 or 533, which will be just like the 266 in it, cept over twice as fast with 128k of L2 compared to the 0k of L2 u have now.

Id say almost 99% sure you CANT run the new P3 FCPGA S370's, or the new Celeron FCPGAS.

--EDIT
I almost forgot...You may want to find the biggest multiplier on the board, and multiply it by 66, and get that Celeron (as long as its no higher than 533, just to avoid any problems as far as an incorrect multiplier goes.
You may also want to flash the newest BIOS from HP for your board, to ensure maximum compatability for the CPU swap, and optimal proformance.

Is that C266 up for grabs by any chance??

[Virtual Infinity]

Hmm I think alpha is looking for 400+

[starcraft_azzkikr]

well the p3 is not a fcpga thingy that you are talking about i think it's a ppga. not to sure but were getting one of those adapter boards for it it's a slot one celeron. so is another comp that is a 333 celery that we are upgrading here and that will go to 500. well you guys tell me what socket it is. i know it's socket 370 but it's odd it's only on a silicon square thingy. the L2 cache is on the bottom w/ the pins and the main die is alone on the top. it has two sides that are "keyed" as in the pins don't go all the way out to the corner.

No, there isn't any L2 cache. It is a slot one chip - you will need an adapter board or "slotket"

[starcraft_azzkikr]

i'm sorrie i made a mistake i meant to say that the p3 chips are socket chips but both celerons are slots. so we need an adapter board for them. that's right the stuff on the chip is l1 cache right? forgot that for a min there.

SA

[AuraEdge]

Ohh its slot 1??
okay
Well you still have to make sure of the Voltage tolerances of your board (Optimally, 1.5, but you can have up to around 1.8v and a FCPGA celeron will still run)
Then you have to get a Slot 1 -> FCPGA Adapter.
If you get a P3, your going to loose 1/3 proformance right off the bat, because of the multilock.

P3's are either Slot 1 or FCPGA.
There is no PPGA P3. The only thing ever made in PPGA were celerons.

[alpha]

No, L1 would be part of the cpu core.

[AuraEdge]

If the celeron 266 is built like the Celeron 366, then the core is on the bottom (along with the ALU, control unit, L1 and every other part of the core), and the top is just a metal slug to protect the back of the Core.

FCPGA will fit in S370, but you have to make sure u buy an adapter thatll recieve FCPGA processors.
