Socket 370 P3 / Celeron overclocking WIRE TRICK???

[Vette73]

Is there a way to change the FSB or Multiplier with a wire trick or soemthing else for the 370 chips, esp the Tualatin ones?

I have a 370 board that has NO overclocking functions but supports the latest 370 chips from VIA and Intel. I like to see what I can get out of one, but the P3 Tualatins cost WAY to much, so looking at the Celerons in the 1-1.4Ghz range and changing the FSB to 133, instead of 100.


Thanks

What board?

 

[TStep]

Try Setfsb or CPUfsb.

This board


It is a Flex board so I doubt it was intended for overclocking at all. But I like to get a Tualatin 370 chip at 133Mhz FSB but the P3's cost as much as some Athlon64's. So I was hoping for a way to change the FSB and get a Celeron and set it to 133Mhz FSB.


I will look at those TStep, but I don;t want to change the PCI/Video Mhz. Not sure what the onboard Uni-Chrome can handle.

Thanks

its not a wire trick so much, as a break a pin off and hope the cpu can handle it.

You got a link to what pin to cut/cover to do it?

I have done the wire trick to P4 Xeons, so I thought there has to be a way to do soenthing like that to the 370 chips.

What speed Tualatin is it as not all can do 133 FSB?

 

[Vette73]

Well I am looking at 1 - 1.2Ghz Celerons. I think most Tualatins hit around high 1.5 to low 1.6Ghz.

How would one use that to change the multi in a 1.0A cely?

I don't think you can. BUT there is a way to change the FSB setting from 100 to 133 with a Pin break or cover. I juts don;t know which one.

Too bad tually motherboards with AGP slots seem to be MIA...

Best bet with Tualatin Celerons are the 1.0A or the 1.1A to hit 133MHz FSB. 1.3 and 1.4 are REALLY tough to 1.73GHz and 1.86GHz respectively. That's like running a P4 at 5+ GHz. Sure, a few people have shown that it can be done, but don't go out and buy one expecting that kind of speed. 1.2GHz is an in-between. Lots of success stories at 1.6GHz overclock, plus lots of failures. I personally had two failures, zero sucess. My 1.0A and 1.1A were pretty much 100% success. With those, you'd get 1.33GHz and 1.46GHz overclocks. You'll probably need to do two things to it, first break off the pin for 133MHz bus detection (either BSEL0 or BSEL1, forgot which). Second, do the "wire trick" for a bit more voltage. I've made a web page detailing the BSEL0/1 pin mods, but the site is temporarily down. Perhaps someone else has such a site.

As you already know, multiplier can't be changed.

Good luck on this and let us know your results. If you can't find information on the BSEL pins and the wire trick, PM me and I'll dig up the info.

Alright, I moved my web page from my work computer to my Clan of the Bloody Fist web site. New URL is:

http://www.bloodyfist.net/computer/fsbpinmod.html

I don't have voltage info on there, but the pin mod for FSB detect is valid for all socket 370 and socket 478 chips.
