Evidently if you ground one pin on the 400FSB Dothans it will force it to run at 533FSB speeds. A really cheap upgrade opportunity.

Get this from Newegg

Ground one pin and evidently it can run at 533FSB all day long.

Might be worth some more research.

That chip should have a 16x multi So it would work out to (16x133)=2.128

The mod on the link was for a 715 series processor. So it runs at (15x133) or 1995 Mhz

I think I'm going to attempt this with a 725 processor once my 9300 comes in.

Maybe Ill go ballzy and go for a 735 (17x133) 2261 Mhz

possibility

Actually this has been confirmed by one person so far. The person that came up with the Idea. I am checking the tech docs for the Pentium-M atm

He on an I6000, gronded the BSEL0 Pin of his Pentium M-715 (15x100) it is now running perfecly stable at (15x133) or 1995Mhz a 25% increase.

Ok I have been reading the intel Documents. This looks legit. There is a pin that controls what FSB speed the processor operates at. Its dependent on the chipset. If the BSEL 0 pin is grounded the processor will properly identify as a 533 FSB processor to the 915 chipset. Looks like we have some good overclocking possibilites here. I also found all the info on pin modding the Maximum Vcore for overclocking.

very interesting stuff

shit, i already have a dothan 1.7ghz in my other laptop that I upgrade. Had I known about this I wouldnt have JUST sold it. It ships out tomorrow

I could have tried it

When my 9300 comes in I am going to order a Dothan 1.7 400FSB and attempt this.

If it is sucessful I will make a guide and post if for all to see along with detailed pictures.


2.26Ghz Sounds great to me, especially for $250 bucks.

250 bucks? You can get a one $70 cheaper on ebay. Some are pulled from machines, some are new.

and I think I will attempt this too, just need more info.

Do you have an documents about this spazilton?

Damn good point.
Better to screw up a used one.

I have the intel tech specs. From what I am reading I have enough info to modify the FSB and Vcore if needed.

Hmmmmmm. Wonder if I should try this with my I6000 with it's 1.5. I have done this way back in the day with a celeron 300a - 450mhz and a p3 700 -933 by applying nail polish to the contact. If it doesn't work just remove the nail polish. Do we have to ground or isolate?

that's a 33% increase man

Mad props to your find
I made sure to link to the orginal post so you could get your credit

Which Dothans run at 400MHz & which therefore run at 533MHz (or do they all only run at 400MHZ)?

i'm not too familiar with that myself. i'd refer to intel's spec sheets

but i thought that the 533 dothans were called sonoma or something

I have to find out what processor socket the I9300 uses first then I will be able to post a listing of compatible processors. There are 2 socket types for the Pentium M.
