Hi there bros,
I have an Intel T2400 core duo processor running at 1.83 GHz (original) with a bus speed of 166 MHz. I´m willing to overclock following your method number 2 or 3, via the PLL Pinmod.
The PLL in use is the SLG8LP465V (opened the laptop to see it), and I have the datasheet. In there i found the pin that I need to separate from the board (FS_A, #41) in order to set the frequency from 166 to 200 (following the table #1 of the datasheet).
I would then connect such pin to a ground pin (with a resistor?), maybe pin #42, is that correct? I realize that there are many ground pins with different descriptions, does it matters in which I connect it to?
Also, do I necessarily need to overclock ram speed as well?
Am I heading the right direction?... just trying to follow your instructions, but I want to make sure I´m not doing anything wrong.
Thanks in advance.
My specs:
Toshiba Tecra A6
Intel Core Duo T2400
2x 2 Gb Kingston DDR2 PC2-5300 667 MHz (333 MHz)
Chipset: Mobile Intel Calistoga-GM i945GM -
Hi
My Compaq nc4400 has CV161PAG and it is not recognized by SetFSB and so on...
The datasheet is not available but I got CV174C's and CV183A's.
Those are partly similar to CV161.
Then I tried pin modding to change 166MHz to 200MHz or above, but I think FS_A (pin 10?) is tied to USB_48 and it maybe needed...
Do you know any suitable OC tool or pin modding?
Thanks. -
Can any one capture the creator setting for D510MO ? I have stuffed up the creator setting. Thanks -
I have a laptop with the Realtek RTM875t-606 clock generator, and an Intel GL40 Chipset.
When I select RTM875T-606 in SetSFB 2.3.166.131 (trial version), I get a "PLL ID Error"!
When I select 'PLL Diagnosis' in the 'Diagnosis' tab (Clock generator drop down menu) and clock on 'Get FSB' nothing really happens. Also the 'PLL Control Register' is empty like in the picture below.
Questions:
1- Would you recommand the PLL mod?
2- What would happen if I do the mod? Would I gain access to FSB1066?
3- What Pin should I ground? is it pin 4 like described here?
4- Assuming that the mod would enable FSB1066, which of the following CPU I should use for the mod? T2370, T5500, T7300, T4200, or T9900?
I already own all of the above CPUs.
Thanks

The comprehensive details of how to TME-unlock mod your PLL and the special setfsb version to overclock is here. -
Edit:
I've read the content in the link(s). What I'm confused about is the fact that SetFSB is not displaying anything in the PLL Control Registers (see picture in my previous post). There are no hex values!!?
Edit 2:
There 3 examples in the first page with the RTM875t-606 clock generator. All 3 have TME-lock enabled. Can I assume that it is the same for mine and that I would need the pin mod too? -
I'm looking for some information about a voltage pinmod for the first gen i7 CPUs, does anybody now something about this, or maybe tried it already?
All I found so far was a mod with a core i5, posted on a russian site, here. Unfortunately it's not very informative.
Any information would be appreciated. -
I am trying to copy what has been done here with the dell 1525. I read the previous posts, but am confused about cutting and grounding the pin. How do i cut the track? is it from the top or underneath the board where the pin sticks down? Once it is cut correctly can i use a radio shack 10k ohm 1/2 watt 5% resistor? where to ground it.
If i get the physical part done right i should be good to go.
I have a t9300 and read that people have these OC to over 3ghz! awesome.
I am also dual booting osx and trying to find a setfsb mac version if anyone has any recomendations.
Thanks, i will post back with progress and pics. -
It is way cooler (tops @ 69 C) than my t9300 @ 266 and very energy efficient. (No extra voltage needed)
I think it is the R0 stepping that does this. I am gonna keep this and use the t9300 only for benches
Does anybody know what's the chipset pinmod for a lane reverse on a GM45 chipset?
I found my answer thanks to nando.

Hey...
I have BSEL pinmoded an Intel T2400 from 166 --> 133 (the 166 --> 200 wont boot, 945GM chipset) just to see if the multiplier looked and it didn't. So, if by any case I would be able to mod the Bios to accept the 200 MHz, will it lock the multiplier then? I mean, if the downclock didn't lock it, will the overclock lock it? -
It is probably not a bios issue. and yes. It is not on the first page but I have done a research on the matter and for 945 and 965 (I am going to check soon and 45) downclock pinmod does not affect the multiplier. Only overclock does..
-
By the way thanks for the info regarding downcloking via pin mod. What CPU did you use for your downclock experiments? -
Tested on GM965 with t5450 from 166 to 133.
______________ with t8100 from 200 to 166.
______________ with QZOL from 200 to 166.
Test on progress on GM45 with t4400 from 200 to 166. -
In your case can the mod be removed?
being able to pin mod to downclock is very interesting since one can have his own home made UVL CPU -
-
I'm looking to bring up the fsb from 133 to 200 on my compaq c762nr (c700 series for search indexing purposes), bringing my t2370 from 1.73 to 2.6.
I have 2 different sticks of ram, both rated for 333 5-5-5 operation. Hopefully, it will be able to run at 400 6-6-6 or better.
It uses the slg8sp512t:
Uploaded with ImageShack.us
The frequency select table is the same as posted on the first post:
CBA
001 133fsb
010 200fsb
011 166fsb
I figure I'll get to 166fsb, so I can change the spd of my ram (runs 266 4-4-4, so hoping it can run 333 4-4-4..)
I see fs_b is shared with test_mode. Did I read right that 3.3V would put the pll into test mode, and I need ~1V?
I'm hoping to do this without lifting any legs on the pll.
Sorry for the lousy picture, but if you can follow it, it looks like I'm removing at least the first resistor (1kohm). The second one seems to have no resistance. I suppose I could cut the trace on the pcb at the double silkscreen lines, and always be able to reconnect it on the surface if need be. That'd allow me to simply use the first test point to obtain 1V somehow.
The resistor connected to fs_a seems to be 40ohm, and the one directly next to it seems to be the only one connected to fs_a. I may be wrong though; I am using a $2 multimeter.
Anyone have any suggestions on the best way to approach this without lifting legs? Will the fact that fs_a is shared with usb be a problem?
I can try to take a better picture if it'd help.
Thanks -
x06 ---> 0.7500v
x07 ---> 0.7500v
x08 ---> 0.7625v
x09 ---> 0.8000v
x10 ---> 0.8375v
x11 ---> 0.8750v
x12 ---> 0.9000v
x13 ---> 1.1250v
I had to go high with x13 because due to the mod I lost access to all the VIDs between 0.9000v and 1.1250v.
I had a Pentium M740 (FSB133) running on a laptop with an Intel i855 chipset. Since this chipset supports FSB100 only, the M740 was automatically downclocked from 1.73GHz to 1.3Ghz. As I result I was able to set all the VIDs in RMClock to below 0.9v. The CPU was so cool that the CPU fan never kicked in. In a sens I created a ULV CPU.
Based on the above I assumed that:
1- dropping the FSB via pin mod will allow enable the CPU to run stable at lower voltages.
2- a CPU that uses lower voltages is a ULV CPU.
3- Lower VIDs means a lower DTP.
4- Lower DTP means the fan will spin less or not at all.
5- Fan that does not spin often or not at all means power saving.
6- Lower VIDs means a CPU with a lower power consumption.
7- 5 and 6 means a better battery live.
Please feel free to correct me on the above if I'm wrong
Back to the PLL mod.
I'm slightly confused. I see that some (like yourself) removed the resistors and made a connection with a wire from the resistor pad to the ground, when others (such as nando4) connected the pad to another resistor before connecting it to the ground.
Why two techniques? and what's the difference between them? -

@ ziddey
You better start the 133-->166 by removing the leading resistor and pull to a VDD point (3.3V) with a small (1k) resistor. After that you should remove the fsa leading resistor and check if it boots. pls make sure that you provide enough voltage.
Good lack!!
You are probably right.
-

-
-
Question: Why don't you just use an 1K resistor and extend it with an ide cable? It's easier and safer. -
any advice?
the pll on my board has very small pins on it. pin 11 follows a very short trace and then goes into a whole. I cant imagine cutting the pin and then soldering a resistor to that pin. maybe if i removed the chip pushed and pushed the pin up. is there an easier way? i checked for continuity on the back of the board, but could not find any direct connections.
is it possible to cut the trace and then solder a resistor to it.
i am on a dell 1525 with a t9300.
thanks. -
nando4 has an amazing thread for Inspiron 1525 and he recommends to cut the track and add a 10K resistor to Gnd.

According to Intel 945 datasheet, the 200 MHz FSB is not supported, or at least not listed in the table, so I figured that I would need some kind of hack to make it work. Are those datasheets as exact as it seems to be?
I undervolted my pc (via RMclock) several months ago and it is running stable and at peak performance at 1.1000V, where the default voltage for my T2400 is 1.2625V. So I´m not sure if I´m missing some voltage for the overclock. What I mean is that if I can boot stable with 1.1000V @ 1.83 GHz, I guess that for higher speeds, say 2.00 GHz, 1.2625V should be alright. Please correct me if I´m wrong.
Also, I was thinking that maybe the problem was related to RAM?
Thanks for your suggestion about the signature, but I´m still not qualified to use that feature (need 5 quality posts...etc), but I will post my specs right here:
Toshiba Tecra A6 (PTA60U)
Intel Core Duo T2400 @ 1.83 GHz (default), FSB: 166 MHz
Chipset: Mobile Intel Calistoga-GM i945GM
PLL: SLG8LP465V
2x 2 Gb Kingston DDR2 PC2-5300 667 MHz (333 MHz) -
I run a kingston PC2-5300 @887MHz without any issues.
Only issue you may have is with your intel graphics but the oc is small (667-->800) so I don't thinks you will have problems there either. Msi U100 users with intel 950 are able to oc their processor (and their ram) from 667-->800 (N280) so I don't think you'll have any problem. -
Oh, so it still possible to overclock my system, that´s great news xD I was thinking that the chipset limitation was a closed door. Bro, if you don´t mind, you can go here:
http://forum.notebookreview.com/har...locking-methods-examples-101.html#post7584835
which is post #1003 of this forum (my first post), and there you can see what I was planning to do, with pics of my PLL and some tables. I can see that you are telling me to do the same thing. But, in one of your previous post you mentioned something about that "48M_0 USB clock output" being in the same pin as the "FS_A", that you couldn´t boot because of that? maybe that´s a big trouble?
-
Disconnecting the resistor leaving from the pll would give you your answer, unless your pll exists on SetFSB list. This way you can change the appropriate bit and check the results before you change anything else on hardware. In any way reconnecting the resistor you removed will provide a bootable system again.

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 ?
-
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. -
.
By the way this is not the first time I used a soldering iron.

@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
-
. The bright side is I gathered all the info I need to do the mod
.
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] -
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

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! -

How exactly can I do that if I get the "PLL ID Error" for most PLLs, for others the values don't match up with the real ones.
Update:
I decided to open up the laptop again, and after I scratched the sticker on top of the chip I found something like this (see photo). I don't think it's the PLL chip. Its datasheet indicates it's some sort of flash memory. The only other IC chip is 88SA8040-TBC. Dam, why is so hard to locate the PLL?
I only want to know whether overclocking my 1.87GHz (533MHz) is possible at all. If not, maybe paying $10 for a 2.26Ghz CPU would be a better idea. Cheers. -
VID 6 5 4 3 2 1 0
--- 0 0 1 0 1 0 0
You can do a VID2 + Vss for +0.05v or VID4 + Vss for 0.2v. Note that +0.2v means that you max Vcore is 1.45v. I think this is too much for a mobile CPU.
You can also try VID4 + Vss plus VID3 + Vcc for an increase of 0.1v.
Please note that there is a down side to volt modes, as after doing them your CPU will lose access to some of the voltages in the Vcore table. For instance, all the voltages between 0.85v to 0.9v will be replaced with voltages in the range of 1.05v and 1.1v after a VID4 mod. This means that a CPU that uses 0.85 or 0.9v in SuperLFM will use a voltage of 1.05v or 1.1v after mod. As a result, the CPU will run hotter and the battery will last less than before
VID4 + VID2 + Vss = 0.25v. So the maximum after mod is 1.5v which is the maximum Vcore a Core Duo and a Core 2 Duo Mobile CPU can attain
it doesn't matter whether you have the i943/i945, i960/i965, or a chipset 4, the VID table is Chipset independent -
Nando4 provides a great free tool setpll which I think bypasses you problem. But I think only ics9lpr113aklf ics9lprs355bklf ics9lprs387bklf ics9lprs397dklf ics9lprs501pglf rtm875t-606 plls are available. Maybe 355bklf is like yours. Give it a try!

I already coded the setpll myself to make it work, but I wanted to be hardware mod, not software[bglf is no go for bkl, I uploaded the bkl on my temporary server as well]
the mod worked well, 266mhz fsb is ON... HOWEVER:
normal voltage: 1.1375 > VID_4mod = 1.3375 on CPU
/-/with my standard 4gb 800mhz, after bios> windows blocks to 0x000008E [ram problem]
/-/with my 1GB 800mhz moded to 677mhz and CL6> from five power on of the laptop, only one is go go, else just siting there, cool and black screen [however still in windows I get error in memtest]
12.5x266 when prime torture to max temperature it hits the wall and underclocks until it cools down - I think I have heat pipe problem, I put my finger on the heat pipe and is not the same temperature at both ends [I knew heat pipe has the technology to instantly transfer heat, so the temp on one end is ~equal to the other end of the pipe]
so the main problems:
the cpu is way to hot -I'll take a look again at the heatpipe, I think is problem with that [Arctic Silver applied]
powering on is not equal to successful boot
ram can't go to 1066 from 800 with CL6
ram isn't stable from 800mhz cl6 to 677mhz with only cl6 [others mem tags are as from 677, I only modified the cl]
... IDEAs?
should I get 667Mhz and flash 800 to it ? [will it run at 667 with 800mhz settings and cl6?] -
.
The VID table below is the same for Core Duo, Core 2 Duo, and Core i.

with VID_4 and fsb 266, the processor is stable but unusable, the temp is going to the max wall... I checked again the heat pipe and doesn't appear to be something wrong with it, it's placed well on the pad but still the temp is more than max. the temp of gt240m is like 35 celsius when the cpu is like >90 and the cooler is going away
)
I then did the VID_3 but is unstable... any ideas ? if not, I will reverse the FSLx mod and leave just tme-unlock
Can I voltmod/raise ram voltage ? [maybe from software with SPDtool ? I saw someone that attract attention by forbidding to make modification to voltage from SPDtool]
in idle I have ~40-45 on processor but when I benchmark it, once it reaches high temp, although the vent is working at max speed, the temp doesn't lower very much >60 [if I do slow-asking tasks, the temp proc stays at ~42] -

What's the part No of your t9300. Mine is a SLAYY. Intel may used some different technology between one of the two.
