PLL Pinmod Overclocking Methods and Examples

[uindauz]

Fujitsu Amilo Pi 3560 upgraded
Intel T9300, nVidia GT 240M, 4GB DDR2 800Mhz CL6 Samsung, ICS9LPRS365BKL

I TME-unlock'ed it and now I want to FSLx mod it.
having TME-unlock, when using SetFSB, I get black screen [when seting SRC Main = PLL3 (B0b2)]
informations and details
do I need to make some volt mod ?
FSLA and FSLC are both 0, to get FSLB from 1 to 0 I cut the 64pin and connect to GND directly OR via 10k resistor ?

My T9300 to go from 2.5 to 3.33GHz with a fs_b to gnd pinmod it needs voltmod. Actually I followed naton's perfect guide doing a VID_4 to VSS pinmod adding to my CPU 0.2V volt more. Your motherboard may need more or less than that so try it out.

You'd better use a 10k resistor. Using direct connection might be harmful to your hardware.

Also great job you have done here informations and details. I would recommend using Kizwan guide to mod your bios so you are able to disable EIST in your bios and gain one extra multiplier with Dual IDA using Throttlestop.

The longer the cable the bigger the impedance. Just make sure you keep the skin on the cable so you don't short-circuit something else.
Question: Why don't you just use an 1K resistor and extend it with an ide cable? It's easier and safer.

I'm not sure that I will do the mod after all. I did some soldering work two days ago. I'm okay when the wire and the components to be soldered are of a decent size, but as soon as the components are small I have a tendency to make a mess .
By the way this is not the first time I used a soldering iron.

I got used to it removing resistors on a dead old motherboard I had lying around and then put them back again. Doing this for a while will build your confidence on soldering small components.

@timohour thanks for your answer
I've just made the VoltMod + 0.2 by connecting AE3 to AE4 {VID[4] to VSS}and tomorrow morning I will do the FSLB pll mod [now in Romania is 16:28]
Is there any way, software of checking the voltmod worked ? because cpu-z shows the same voltage [as I know this voltage mod is kind of internal and won't show up except if you know exactly what temp you had before =if temp goes up, so did your voltage]
and my 4GB ram can't be flash so I am using now for testing a Samsung 1GB DDR2 800Mhz which I flashed from 400 to 333 [667Mhz] and only CL6

now is VID_4 +0.2, if 266 is ok, I will to try to switch to VID_3 +0.1 and test again, by the end of the week I will make a topic about this because I made every mod to this machine

I won't be able to get my hands on a faulty laptop motherboard to play with until September . The bright side is I gathered all the info I need to do the mod .

I'm not sure if you're aware of this but depending on your CPU max Vcore, the VID3 or VID4 + Vss might increase the voltage by 0.1 or 0.2v as it might leave the max vcore unchanged, like this.
A quick way to check if the volt mod worked is to stress the CPU with orthos or a similar software. If the mod worked there should be a significant increase in the CPU temperature, I would say an increase between 5 to 10c.

I'm sure the tutorial would be instructive. I can't wait to read it

timohour maybe you can help me, you have the T9300...
using RMClock, can you say what is your maximal VID ? it looks like mine is 1.2500 [although I made the VID_4 mode, as you did]
[my laptop is Fujitsu 3560, T9300, chipset Intel PM45, DDR2]

Voltmod won't show on any software (at least of my knowledge).
But how will you understand the difference?
The answer is simple.
Before the voltmod and after the pinmod on my pll, my t9300 wouldn't boot not even to bios (black screen). Doing a VID_3 to VSS (adding 0,1V) would boot to bios but OS would give a blue screen. A VID_4 to VSS would boot both bios and OS and pass every bench asked.
The actual Vcore would be Voltage shown on your software + voltage you add (eg VID_5 to VSS + 0.4V, 1.25+0,4=1.65V).
At least that's what I understood reading socket p papers (pm45, pm965).

I am also adding the info that you can also "combine" voltmods, meaning that if you need for example + 0.3 you can do a VID_3 to VSS (+0.1V) and VID_4 to VSS (0.2V). I haven't tested yet though if this works if you need +1.75V and you can do VID_4 to VSS (+0.2) and VID_1 to VDD (-0.25). There is no reason it won't work.

@timohour thanks for your help because you are crucial for my steps +1
it's strange because on some motherboards [I will test my desktop and my girlfriend laptop, as well as many I can get my hands on with RMClock] the maximal VID is reported by RMClock, but passed... ?!
now it's 00:30 in Romania, I did an appointment for 8:00 for moding [doing all hardware mod with pro tools], and we will know for sure until evening exactly how the ICS9LPRS365BKL work... the needs taught me how to program setfsb using pll diagnostics and make setpll definitions [manual bits calculation and representation]
normal vid is 1.138 [1.1375], VID_4 moded is as calculated 1.3375
using Fujitsu is hard for bios moding because they use some specific extension to their bioses, I will investigate that laterI did contact abo [SetFSB creator], I already donated him, he replied a few times, however I explained all about *BKL problem with PLL3 but no interesets from him with updating the SetFSB [too bad] -I think because FSB-PCI beeing locked to each-other /as I said, if everything goes smooth, I will make some topics about it
sorry for my english if any mistaked, I'm from Romania and it's not my 1st language :P

I have a Dell Inspiron 6000 laptop with a recently upgraded 128MB mobility X300 OC'd to 418/301 from 297/216.

It has a Pentium M 750 1.87GHz (533MHz) and as I'm about to spend $10 to buy the 735 1.7GHz (400Mhz) for a pin mod to 2.26GHz I stumbled upon the subject of software OCing CPU in laptops. I have tried some default PLL settings with both clockgen and setfsb, but I can't seem to get it working (i.e. change the clock speed of the CPU). I even tried ICS954201BGLF available on setfsb since ICS954201BG is what's shown on the schematic. I heard people have OC'd their P M750 1.87 to 2.26~2.5 stable on their non-Dell laptops, so that's what I would like to do. However, some have said that overclocking Dell Inspiron 6000/ Dell laptops is not possible in software, is that true? If so, I will just spend $10 and not need to spend time learning the various things related to this thread.

Here's the schematic for the motherboad I found just now. Notice on the second page the clock generator is said to be CY28411ZCT whereas on page 6 it's ICS954201BG. I don't like to open the case again unless I know it's the last time (because too many times already) for checking the PLL model or replacing 1.87GHz with the 1.7GHz. This would be the final upgrade after many things I have done to it, from 512MB ram to 2GB, 64bit 64MB hypermemory to 128bit 128MB dedicated, as well as spray painted it black. It works great after 5.5 years, I can even play F2P Combat Arms and A.V.A and watch HD X264 videos on it. I would like to squeeze some more power and a few more years from it before I let it retire (10 years altogether would be nice, LOL), and hence the CPU mod/upgrade.

I hope someone here would enlighten me on the subject by either telling me what I need to do or at least pointing me to the right direction. Perhaps simply a quick short reply would be great. Thank you!
