can these chips be used in motherboards already running a p3?
my motherboard support a max of 150 fsb and 10x multiplyer giving me a max of 1600
because this chip is only 1.3 does that mean i can use it on my board?
check sig for mobo details

Not sure if I understand the question. It sounds like like you already have a PIII 1 GHZ. Are you talking about getting a new one. If so, what are you talking when you mention 1.3 above?? Intel will shortly be releasing a new PIII 1 GHZ which will run on 100 MHZ FSB and has a multiplier of 10X.

If your talking about a Tulatin [maybe spelled wrong] then yes you will need a new MB, if its the CPU the above post mentioned i'm not sure. I do know that Intel made a few 100 p3 1g's but they did not overclcok that well i hope these new CPU's will do much better, i think Placid should know the answer to your question.

goodluck

Well I am not sure what cpu you mean as intel dosent list any 1.3ghz cpus yet.
They list a 1.133ghz cpu thats a tualatin cpu that would require a different motherboard.
They also list a 1.1ghz cpu that is a coppermine that you would need a bios upgrade to run because its a 100fsb cpu so you would need a multiplier of 11.
Other than that your board should be able to use the 1.1ghz cpu.

I think Placid is right as near as I can tell. Check out the official Intel S-spec chart at the below listed link. Why didn't I hear about this 1.1 gig 100 FSB P-III before? The 1.13 gig chip listed is the Tualatin which is not a direct upgrade. I had predicted the first stepping version of the Tualatin would probably be TA0, but looks like Intel is using TA1 stepping instead. Sure Intel, anything to make me look bad. LOL.

Other than that your board should be able to use the 1.1ghz cpu.

Multipliers are locked. Therefore they are irrelavent. It really doesn't matter whether your Bios knows about an 11.0 multiplier of not. Nor does it matter whether the board has a jumper setting for an 11.0 multiplier because it will run at 11.0 whatever the bios says or thinks. Now, if you were to get ahold of an unlocked engineering sample then it might become relevant and the CPU might not be able to run at it's full speed because the motherboard wouldn't be able to set the multiplier that high, but for a locked cpu it really doesn't matter what the bios thinks about the multiplier. It's hardwired inside the chip.

Of course, that's not to say that this CPU would work in an older motherboard or that a new bios might not be needed to run this CPU, but if a bios update is needed it's not because of the multiplier. It would more likely be because of some change in the way the CPU needs to be initialized or because the CPU wasn't properly identified by the bios or because of a necessary microcode update. However, microcode update usually are not absolutely required for the CPU to work, but there could be stabiltiy issues without them as microcode updates are sometimes used to fix bugs in CPUs. Of course if your willing to modify your bios and know how to use CBROM ( for Award bioses) or AMIBCP (for AMI bioses) you can actually extract microcode updates from another bios and add it to your own.

My Tyan Tiger 100 doesn't have a 10.0 multiplier. Nor does it have the CC0 stepping microcode update in it's bios, but none the less it will run a pair of cc0 100Mhz FSB 1000Es just fine.

I think your talking about the new Tualatin chip from intel, they are supose to only work in fc-pga2 sockets, but dont throw away your fc-pga boards JUST yet..

I'll have some more news for ya'll in mid augest, so hang ten :)

thanks for the posts guys, what i meant was that i have a 1gig and i want the new 1.13 gig
hope this helps

The 1.13 is, I believe, a Tualatin and would require a new motherboard because the input/output levels of the bus signals have changed. The 1.1Ghz 100Mhz Fsb chip may be a coppermine-T. This one supposedly might work in existing motherboards in a single CPU configuration. I'm not sure about whether it would work in a dual configuration or not. I believe the coppermine-T is based on the same process used to manufacture current coppermines and is suppose to kinda bridge the gap between coppermine and Tualatin. Based on what I've heard it is supposed to work at either the old bus signal levels in older coppermine motherboards or the new lower signal levels in Tualatin boards.

Of course the bad news is that the coppermine-T will probably not overclock like the Tualatin may. Since it's based on the same process as the older coppermines it's probably already running almost as fast as it can already. The Tualatins on the other hand may go higher. I've seen a few sites that claim to have tested the Tualatins and gotten them upto somewhere between 1.3 and 1.4Ghz.

I might also add that there should be an adapter out by this fall that will allow the Tualatin to be used in older P-III mobos. It might be a bit expensive at first. There is a persistant rumor that some older BX boards can support the 1.13 gig Tualatin, but I have yet to see a reliable source for this information. The main reason that the Tualatin will overclock better than the regular P-III processors is that it has a new 0.13 micron core with lower default voltage, thus it runs cooler. The maddening thing is that Intel could of easily made the Tualatin CPU backwards compatible to fit the regular socket 370 mobos. Why they didn't is anyone's guess.

Intel has released 1.13 PIII samples to OEM's. However, it seems that these parts will not be offered for sale.

Here (http://www.watch.impress.co.jp/akiba/hotline/20010707/newitem.html) are some pics of the 1.26Ghz version. I'm not sure but i've heard that the 1.13s may already be available in japan.

As for slot 1 1.13Ghz PIIIs. I think you may be thinking of the ill fated cc0 slot1 1.13Ghz chip that was recalled before it was ever actually released because of stability issues. That was not a Tualatin.

the tutalins will work with the bx440 chipset because of its voltage management, it will also work with the i815 chipsets

same with the socket370 ones, i doubt they will come in at 1.13GHz, buy that time they will allready have better competition from amd
