Dude, just to make sure... you did check all the options that your
notebook's bios has to offer, right?
Just asking.

Ok, this is the last post on this subject.
I finally got around to pin modding the CPU.
I removed the pin completely since it was easier than painting it.

Well, no change. Same speed, no overclock. :noidea:

No matter what I try, NOTHING. I mean, even the *%(#* Pin Mod,
which works with every other computer in the *#($* planet, does
not work with the *$(#@! 9100!!!

Screw it. I'm out of ideas.

Sorry.

I deleted my last 4 posts since they had so many inaccurate comments.

I have used SetFSB and even communicated to the writer on a
few occasions. He send me 2 different prototype programs.
Both failed, He advised mt to resign myself. This computer
is made specifically not to overclock.

So you know what that means?

HARDWARE MOD!!!!!

The Tecra 9100 has a Pentium 4M Northwood core. This means that it
is still a Pentium 4 and it is a 478 pin socket just like the desktops
without the heat spreader. The Pentium M is COMPLETELY different.
It has 479 pins but is really a heavily modded Pentium 3 core and it is
NOT AT ALL compatable with Socket 478 (looks the same but is wired
differently).

Pentium M = Centrino
Pentium 4M = Pentium 4.

Fact of the matter is, a P-M 1.4ghz is probably faster than a P-4M 1.8ghz.

My only other options are:
1. Buy a 2.2ghz Pentium 4M on Ebay
2. Research or discover some sort of hardware mod.

I have NOT given up yet!

I recently found a pinmod to change the FSB from 100 to 133 which
would make my 1.8ghz oc to 2.4ghz.

It may be a month or so before I have the time (and courage) to try this.

I'll report back (as usual) for the final results.

Hm...if its Socket 479 its a Centrino Notebook ?  :noidea: if yes, you can download "SetFSB" for ACER 1692...


-- Veröffentlicht durch MidnightPilot am 13:44 am 25. Juni 2005

It is a socket 479. It's really a heavily modified Pentium3.
They are known to be very good overclockers. I can't seem
to find a way to OC the damn thing. I'm still looking for:
Socket479
1. Pin mod
2. "Wire trick"
3. software mod
4. hardware mod
5. anything else

FSB adjustment by software, doesn't work. Mabie a hardware mod.
I'm still looking for a PLL chip type.

My poor Tecra was dead for a month. a capacitor fell off the I/O board
and killed it. I bought aother Tecra on ebay for parts source so now I
can experiment.

Remember, I'll take ANY suggestions.

Your laptop is definitive one with an pentium 4 mobile.
With socket 478.

Why not OC it, when it is possible?
I OC my notebook with an DESKTOP P4 and it is not very hotter compared to default clocks.
Check out if the degrees stay stable when OCed, maybe you know the toll MobileMeter.

A P-M with socket 479 is NO PENTIUM4!!!

A P4-M is a special version of P4 with lower voltage. The P-M has a completely different Core, mot L2 cache (1 oder 2MB), only 100MHz (the new one 133) FSB an so on .... ;)

Actually, that didn't work. (thanks anyhow)
I DID find the 3rd screw (insert joke here) which was from the bottom
right next to the memory access panel. (who knew?)

Only one chip was visible:

ALPS        3889
3DA3DT336B
222        TO2 (or T02)

Is this a PLL chip. (I'll be looking up info on google)

MP

P.S.

Nope, it's NOT a PLL chip (DAMN!).
Back to the drawing board.

May be you have to push it a little bit down (away from the screen) to get the keyboard out of the chassis but it should be enough to push it only a little bit - be careful, it's a nice notebook ;)


-- Veröffentlicht durch MidnightPilot am 3:48 am 15. Feb. 2005

I tried to take off the keyboard. The keyboard strip was removed and
2 screws removed but the thing didn't want to come out and I wasn't
in the mood to force it out.

More when I find what is holding the center of the keyboard to the
computer. :noidea:

Is there a PIN mod for P4-m 479 Sockets?
Is there a PIN mod Guide for P4-M 479 Sockets on OCinside?

I know the risks of OC'ing a laptop, I know the dangers of OC'ing
a laptop. I posted my sucess with OC'ing a Tecra 8000 to show
that it CAN be done. I know that I can buy a P4-m 2.2 or 2.4GHZ for
$40.00. That is not the point. I overclock so I can get more with what
I have. And I have a P4-m 1.8 GHZ that wants to run at 2.4ghz.

OCinside: I have not had time to open my Laptop and find out which
PLL chop I have. I'll have time in a week or so. i will contact you then.

Thanks for all of the help.

i think what IVI means is, that notebook OC is alway more dangerous than on desktop computers.

notebooks are optimized for low temps and silent cooling and if you raise temps by overclocking it could be that your notebook is going to be damaged and maybe you loose your guarantee...

so think twice before doin' it...


-- Veröffentlicht durch ocinside am 11:44 am 23. Jan. 2005

I've worked a lot with these notebooks, but I don't know the PLL IC of them.
So you have to open the notebook or try all PLLs of the program :blubb:
May be you're already able to see the PLL IC if you take off the keyboard strip, then srew off both screws of the keyboard and take it out.


-- Veröffentlicht durch MidnightPilot am 4:47 am 23. Jan. 2005

I was able to overclock a Tecra 8000 Pentium II 266 to 320mhz
:thumb:

I used the Soft FSB, For the 9100 I still need the PLL chip info.

If any of you can get me THAT info, my problems are solved (?)

-- Veröffentlicht durch IVI am 22:54 am 22. Jan. 2005

notebook-OC? sorry, but this doesn't make any sense.

furthermore (99% of all) notebooks don't have the features to overclock ...


-- Veröffentlicht durch MidnightPilot am 4:12 am 21. Jan. 2005

I have a Toshiba Tecra 9100 with a 1.8Ghz Pentium 4M that I want to
overclock it but nothing seems to work.
I tried Soft FSB but I don't know which PLL file it has and even went
as far as looking for a dead MoBo so i can manually look at the PLL.

I think the P4M can make 2.2Ghz or more but I am at a loss.
Is there ANY software or hardware modifications I can try?

Sincerely.
