Celly 900 really 600?!?

[takiwa]

Sandra reports my CellyII900 as a 600 on a 66FSB...could this be an example of Intel o/c'ing there own chip at 100FSB, because it was capable of the higher speed? Do I really have an o/c'ed 600? Has anyone else noticed this, and what are your thoughts on the matter...I'm sure Intel has other chips that fall into this catagory as well...

Sandra has a tentency of misreporting any number of things. What does it say at boot-up?

[takiwa]

I know I have a 900...that's what was on the box, and what it says at boot up is based on the FSB...what I am pondering is if the internal workings of my chip were at one time designed for or sold as a 600, and then Intel said, "Wait, this thing'll do 900 at 100FSB with no problem...let's mark it and sell it as a 900..."

That's my question...did Intel o/c this chip from the factory?

[LutaWicasa]

I wouldn't think Intel would be remarking their own procs and then not have enough sense to update the microcode to show what they want it to. If ya let the mobo set the speed what do ya get?
Besides, I see you've had it up to 1.2 GHz aircooling......haven't seen too many Cel II 600's capable of that :)

These chips of different speeds are all made from the same wafer. They are tested for stability at certain speeds, then given a massive amount of leeway, are labeled and neutered to a certain speed.

It is very well possible that a 600 and a 900 came from the same wafer, but chances are in your case, it's just Sandra flaking out. But there is the slim possibility that that chip may very well have been cut for a 600.

What's the default voltage? The Celeron 900 was only produced in the cD0 stepping or 1.75v default. Other than being a newer stepping, in a way, with it having a 9X multiplier the 900 is sort of a factory overclocked 600.

the best proggy to tell you is one from intel to "identify your chip" it noticed that my cpu was oced even though it wsa at 133 fsb for 800mhz.....gave me a little warning "you cpu is in a state known as overclocked, this may cause stability and other problems, and may shorten the life of your chip"....

[takiwa]

here's the thing...Kingslayer hit the mark I was aiming for...and so did batboy. It is a cD0 chip, at 1.75 voltage...but I think that Intel does batch these chips together and then decide after testing what it should be labeled...would certainly save on production costs from chip to chip...especially when you have the technology to make a 600 that will perform safely in the 900 range! funnyperson1, I have that Intel program, and here's the kicker...when I UNDERclock to a 66FSB, it says I have a 600 with no warning of underclocking...hehe...I don't know why Sandra picks it up as a 66FSB 600, but someone else has posted that in this forum before...I read two posts like that, actually...makes you go, "hmmmmm....", don't it?

[funnyperson1]

well the problem with that is that there are no Celly 600 cDos....intel does not make them as they are outdated (a 100% oc would vbe nice though :))......there is no reason for intel to make a 600 anymore, noone is buying these chips....

[Lancelot]

That would be a 50% OC

Anyway letting the mobo set it at default won't work. My boxed Celly 800 defaults to 533a (8x66 instead of 8x100) even with a BIOS update for the new 100FSB cellys. The update only makes sure that 8x100 is indeed listed in the BIOS when you're not manually setting up things, but you still have to point it out in BIOS setup yourself. Intel has caused this scenario themselves, cuz the Celeron2 is and acts just the same as a P!!!, same microcode, same multipliers, an now same 100Mhz as earlier P!!!'s. Most software just recognizes it as a coppermine P!!! with SSE. And basically it is, but not quite...ehh!

That's what I was saying...it's like with the 100FSB, Intel has "o/c'ed" the Celly, in a way...maybe? I'm lacking the technical knowledge or language I need to describe what I am saying, so if I confuse anyone, I am sorry...
