Help!Could someone tell me how to find the 9LPRS325 datasheet?

Hi,Everyone
I want to overclock my Toshiba Satellite M100,T2350,133x14=1.86MHz now.
I googled several days,couldnt get any info about the PLL but here.
Could someone help Please?
My PLL:
ICS9LPRS325CKL
72-pins
Pic:
I just wonder which pin should be mod,or Someone has a similar datasheet.
and How to avoid Intel Chipset 6x multipler lock?

Thank you for any advise!
:smile:

 

You could ask them directly for datasheet, fill the form here.

I did get partial datasheet because it is customer specific according to them but its good enough for me for overclocking. Ask them politely, with luck they will reply you back

 

You must disconnect the pin from it's track to the MCH so that the chipset wont know that the value has changed. Usually there is a resistor comming from the pin, removing that resistor would do the job.

 

Thank you!
I submit my request,but it reply he was on Annual Leave now.

 

Thank you for the explain!
Here is 2 questions comes:
1.)In some cases,Is the FSLB pin same as the pin which link to the MCH?so cut it off,Everything would be OK?
2.)Where can I find the MCH specification?in the PLL's datasheet?or Mobo circuit diagram?

 

Yes, the FSlB, FSlC and FSlA pins are linked to the MCH, so if you change any of them, make sure that they are cut.

Should be in the mobo circuit diagram. You may also find a datasheet on intels website (if you have an intel chipset).

 

Get it!
It's hard to find the mobo circuit diagram.I've tried.
Otherwise,Is the TME pinmod related to Set FSB in "SetFSB software" only?
In my case,a TME pinmod is No need at all?
Thanks for your answer!

 

Yes, you are right about the TME pinmod.

 

Many thanks to you!moral hazard!
Have you ever pinmoded a 72-pins PLL?Share some experiences please.
I'd like to have a try......

 

I do have a 72-pin PLL in my notebook (ICS9LPRS113AKFL), but when I asked IDT for the datasheet they didn't respond. Later I found a guy who modded the same PLL and emailed me the pinout:
Google Translate

I was going to try the FSlB mod, but then I upgraded my CPU to one with a 266mhz FSB (thanks to Ayle, he sent me the SP9400 for free).

This meant I had to do an FSLc pinmod, but the FSLc pin was also used for something important if I remember correctly. So it's a bit difficult for me to do the mod.

TME is disabled so I can use setfsb or the MSI turbo button to OC.

I was still thinking about the pinmod, but my motherboard is failing (my screen goes pink/green and it looks like I will need a new notebook soon).

 

Some info (unverified) ICS9LPRS325CKLFT. Use at your own risk.

Code:

Pin
41 FSLA USB CLK
45 FSLB TEST MODE/24Mhz
23 FSLC REF0/TEST SEL

ABC
100	133MHz
110	166MHz

 

That seems to fit this table:

oh,Only a FSLB mod is needed in my case,i guess.
So the most important is getting the datasheet.

 

Thank you very much for this things!
Could you please send me the ICS9LPRS325CKLFT's datasheet?

 

Yes!
I've seen that miracle. Great job!True Man!

 

Fortunately,I got the Mobo circuit diagram!
Thank you!My friends!

How could I do?Cut off the 45 pin?and get rid of the R588?
Thank you very much!

 

I would just get rid of R588 and r587, then I would also connect the FSlb pin to GND.

I'm not 100% sure though, you might be better off lifting the pin and connecting it to GND without touching anything else.

 

Thank you!
First,lift the 45pin and connect to GND.===>change FSLB from 0 to 1.
then,remove the r587&r588.===>hack the 6x multipler lock.

Is this right?

If I just only lift the 45pin from the pad,Does it work?

 

When you lift the pin, you disconnect it from the MCH, so you avoid the 6x lock.

You dont have to do this if you are going to lift the pin.

lift pin ===>hack the 6x multipler lock.

It's has a good chance of working.

 

OK,I'll do it at once!
Thank you very much!

 

Help!
After I CUT OFF 45pin from the pad,(so tiny that I cant lift it.)My notebook is black screen and not boot.
If I cut it off,and connect it to GND or 41pin,the notebook is starting as usually.
Why?Is the 45pin wrong?

 

So you have connected fslb to GND?

What do you mean by "notebook is starting as usually"?
Do you mean it's working fine or are you having problems?


When you disconnect the pin, I thought your notebook would either boot or it would give you a black screen. And if you got the black screen the right thing to do would be to connect it to GND (which it looks like you have done).

Everything should be fine after you connect it to GND, unless the overclock is not stable, maybe you need more voltage or better ram. Or maybe flash the ram to a lower frequency and increase the timings (use thaiphoon burner or SPDtool)


A similar thing happened to me, I needed to disable TME on my toshiba notebook, when I disconnected the pin the notebook just gave me a black screen. But after I connected the TME pin to GND everything was fine.

Some people have reported that they did not need to connect to GND, maybe they had an internal pull down resistor or something.

 

Yes,FSLB connected to GND(a little circle dot nearby the PLL,and I tested that dot is conduction with the screw.)
The notebook ran normally without any error.

I cut off it,not lifting.then I got a black screen.

I dont think so.Because When I got the black screen,The power led turn red(should be blue)and flashing. maybe some ERROR CODE?

Sorry,I cant find the TME pin in the datasheet.

Thank you!

 

So it ran normally, then what happened?
What is the problem now and what do you think caused it?

Sorry I am having a hard time understanding what went wrong.

 

Thank for your patience and Sorry for my poor English.
The problem is:
1.)I cut off the 45pin,the notebook give a black screen and the power led turn red,It should be blue when it run before.
2.)I cut off the 45pin,and connect to GND,the notebook run like before.(at 133*14=1.86GHz)
3.)I cut off the 45pin,and connect to 41pin,the notebook run like before.(at 133*14=1.86GHz)
Do I mod the wrong pin?

 

DimRacker I don't have the datasheet, if I did it wouldn't be unverified. You might possibly find lifting the pin puts the PLL in TEST mode and that you need to use something like ~1V to enable FLSB high but not engage Test mode. Perhaps you can make a resistor divider to give you that.

 

Yes, now I see what is wrong.

Originally FSB = 133mhz, so:
FSLc..FSLb..FSLa..CPU-MHz
L.......L.......H......133

You want to connect FSlb to 1v as Dufus said, not GND.
You will get:
FSLc..FSLb..FSLa..CPU-MHz
L.......H.......H......166

166 x 14 = 2324mhz.

You may even then want to try connecting FSLa to GND to get:
FSLc..FSLb..FSLa..CPU-MHz
L.......H.......L......200

200 x 14 = 2.8ghz.

Sorry about the mistake yesterday.

If you wanted a really high overclock (not sure if this will be stable), try connecting both fsla and fslb to GND:
FSLc..FSLb..FSLa..CPU-MHz
L.......L.......L......266

266 x 14 = 3.724ghz (I think this is unrealistic and probably would need a lot of voltage, but you should be able to pinmod the CPU or the voltage regulator for more voltage if you wanted to try this).

 

Thank you!
I think the L.......H.......H......166 is enough.
Where can I get the 1v?

 

Well you could try connecting fslb to fsla (fsla should already have the correct signal, 1v).

I'm not 100% sure that will work, but it's an easy thing to try.

 

I've tried it yestoday,but it was running at 133*14=1.86,as before.

 

Do you see any pin in your datasheet that is 1.05 to 3.3v pwr?

I don't know how to make a resistor divider though (which I guess you need).

 

Agree!
Would you please help me?I'm a beginner in circuit.So Sorry!

Ok thanks I've downloaded it.

 

I'd be most grateful!
I'm waiting for you.

 

I'm not exactly sure how to do it. I think the VDDREF pin should be 3.3v, how to get that to 1.05V I don't know. Maybe Dufus can tell us?

 

Maybe add a 2K resistor between 45 and 18?

 

Someone told me that connecting two diodes between 45 and 18.
Is that right?

 

The best way to do it will usually depend on the layout of your board but basically its connecting 2 resistors in series between 3.3V and 0V to give ~1V.

For instance using a 1k8 and a 1k resistor connected in series and between say 3.3V and 0V with the 1k connected to 3.3V and the 1k8 to 0V will give ~1.2V where they join assuming high impedance of FLSB. I'll try to do a quick sketch if your not sure.

DimRacker, do you read Chinese?


Edit: The attached below should be okay to use without a buffer resistor between the PLL and divider. If 1.05V is enough you could try using just a 10k resistor between lifted pin 45 and +VCCP. That would be easiest to test.

 

Thank you very much!
I've tested that the VDDREF 18-pin is 3.3V,When the power button was pushed instant.
So I using two diodes(IN4007) connected in series between 18 and 45,I still got a black screen.
I am Chinese.
Thank you for all you’ve done for me!

 

Thank you very much!
Where is the nearest +VCCP from the PLL?

This is my mobo circuit diagram:

I found the positive pole of the battery which is +3.3V to GND.
And I used a 10k resistor between lifted pin 45 and it,but it's still black.

 

VCCP is 1.05V. You can see it on your earlier post


If your lucky R587 will be somewhere near the clock gen but without a component layout drawing you'll have to search for it.

 

I found the R587's place in the reverse side of clock gen,but there is no resistor in this place.
It's hard to connect,I'll try again.
Thank you!

 

If it's awkward try looking for something else with vccp that's easier, there will be more than just that one resistor using it.

 

Thank you!
I've tested VCCP with a universal meter,It is connecting to GND.0V


Nearby the PLL,I found some points that connected to VCCP.


So I conected a 10k resistor between VCCP and 45pin,the notebook was running at 133*14=1.86.

Also I found some points who has different voltage:0.6v,1.1v,1.2v,1.5v,1.6v etc.
Could I connect a proper one to 45pin?

 

I've tried 0.6v/1.1v/1.4v connecting to 45pin,all of them wont work.
What's wrong?
I dont know why there isnt TME pin in the datasheet.
Maybe this PLL could not be overclocking?

 

Okay, maybe 1.05V isn't the way to go, try the resistor divider between 3.3V and 0V to give 1.2V. The PLL supply is 3.3V so you should be able to find something close by.

If you only have 10k then you could try 2 10k resistors to give 1.65V. If it boots at 133 still double check that is the voltage you are getting on pin 45 with your meter.

 

Thanks God!You still online!
I'll try it now!
