PLL Pinmod Overclocking Methods and Examples

Can you please help me? Am willing to learn
Thanks

 

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

 

I believe T9900 will not work since GL40 maxes out at 800Mhz FSB CPUs. A T2370 is a bit oldish. Leaving then the T7300 and T4200 of which the T4200 is a better OC bet being 45nm tech and tend to run higher VIDs.

The comprehensive details of how to TME-unlock mod your PLL and the special setfsb version to overclock is here.

 

thanks nando4

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.

 

That's true. I just pll pinmod oc my T4400 from 200 to 266 @ 2.93Ghz.
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..

try to give some more voltage to your t2400. also what's your pll and on which laptop. (you can add your laptop to your signature so it will be easier to help)

 

Can you explain how did you do the PLL mod. Did you remove the resistor completely? or just unsoldered one of its ends? What tools did you use for the mod?

By the way thanks for the info regarding downcloking via pin mod. What CPU did you use for your downclock experiments?

 

I removed every resistor leading to fslb and pulled fslb to Gnd with a small IDE cable. A screw driver and a soldering iron.

Tested on PM945 with t7600
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.

 

Once the resistors removed, does the CPU still boot at its nominal FSB? for instance will a T4400 boot with FSB 200 or 266?

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

 

The result depends on the laptop. For example, when I did the mod on my Fsc U9200 nothing happened. This time (lenovo Y550), when I removed the 2 resistors CPU locked to its lower multiplier @ 200mhz BCLK! If I want to undo the mod I have to reconnect the resistors I removed. I still don't understand why this happens but I don't really care. However when I tried to remove resistors leading to fsla it didn't boot! This is probably caused because it is used also for a USB signal needed on boot. However there must be a work around. I can't probably go further because thaiphoon burner doesn't flash my rams so I didn't try it.

I disagree with you on this point. In my opinion the higher the BCLK the better the power consumption. You can very easily make an under volt pinmod and use Throttlestop to avoid using higher multipliers. However it can be used by users who want to oc pci-e bus. They maybe can underclock the CPU and then do the pll pinmod to get back to previous frequency. I didn't test this feature yet but I am soon gonna try since I need the extra pci-e bandwidth for my eGPU.

 

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

 

I did undervolt via pin mod a T5300 and a T2060 a couple of years ago. Because of it's low FSB (i.e. 133), the T5300 was stable with the following voltage:
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?

 

I always recommend a resistor since if the PIN is a high (1) AND doesn't have any internal protective resistors, running it directly to GND would create a shortcircuit.

 

@ 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!!

I used to have a T5450 10x166 @ 1.6GHz. I was able to do a OC pinmod on a gm965 chipset causing multiplier to lock @ 6x. This way I had a 6x200 @ 1.2GHz, running at lower voltage than the undervolted 6x166 @ 1.0ghz. I never however tested undervolting t5450 10x133 @ 1.33GHz so I am not able to make a compare between the three.
You are probably right.

They are not two techniques. The result is the same since you have a low signal to your fsl_b. However the orthodox technique is to use a resistor. I couldn't use a resistor because I was careless removing the on board resistors and there wasn't enough room to connect a resistor. Anyway the physical impedance an small resistor and a small IDE cable is almost the same.

 

If I use a cable only, is there a limit to the length of the cable? I mean what's the minimum or maximum length of the IDE cable to get a resistance of 1k?

 

You won't have 1k but a 2cm of IDE cable will be a few ohms, enough to do the job.

 

Is it okay to have a longer cable? like 10cm?

 

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.

 

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.

 

Cutting the trace and then solder an IDE cable on it which will lead to a resistor would be the safer way to go.

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)

 

That's what I meant when I said not a bios issue. Chipset limitation is beyond bios and you can do nothing to change it. However you can run @200 if you just to the fsla to LOW pinmod. This way you trick your chipset that the cpu is running @ 166 while pll gives signals for 200MHz operation.

RAM won't be your issue unless you are going more than that. (eg 266MHz) (same goes for voltage)
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?

Now that clarifies a lot of things in my head, thanks bro.

 

On my SLG8SP556 the FS_A shares also USB_0 signal. When I removed the resistor that leads from pin 20 (USB_0/FS_A) my system couldn't boot. However all systems are not the same. I mean that there are systems that use PCI signal on boot (my U9200) and other that not ( reference to the 1st page).
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 ?

 

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.

 

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

 

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!

 

Check your PLL vendor (ICS or Cypress) by probing it's details as described here.

 

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.

 

Considering a Vcore of 1.2500v, your VIDs sequence is
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

+0.3v is not possible if the CPU default max Vcore is 1.25v. With 1.25v the only possible volt mods to increase the voltage are VID4 and VID2.
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

Is your max Vcore 1.2v or less? If it's 1.25v like uindauz T9300, then the VID3 + Vss does not have any effect since VID3 is already equal to 0.

1.65v cannot be reached in any Core Duo, Core 2 Duo, or Core i. The maximum for these CPUs is 1.5v. The old Pentium M is a different story since its maximum was 1.708v

it doesn't matter whether you have the i943/i945, i960/i965, or a chipset 4, the VID table is Chipset independent

 

How did it go? I hope everything runs smooth.
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!

As long as I remember max Vcore was 1.2V. I am not sure though cause it has been a long time since I gave away my U9200. I recently use my T4400. (I have the T9300 lying around.) I would test as soon as I get back home (I'm on vacations). Right know I'm posting from my iPod... (damn! it's too difficult to type on glass. )

I wasn't aware of that. I thought max Vcore was around 1.7v. Actually I do the overvolt through trial and error.

 

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?]

 

I find it easier to identify the max Vcore with RMclock or CPUZ, and use the table below to identify the corresponding VID6 to VID0 sequence. This helps knowing what mods can and are worth doing .

The VID table below is the same for Core Duo, Core 2 Duo, and Core i.

 

Another way of doing it is a straight % overvolt can be done by modifying the Kelvin sense feedback lines used with the voltage regulator to use a resistor divider. See example performed with the CQ45 overcock+overvolt.

 

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]

 

^This is highly interesting, thanks for the link! I'll have to take a closer look at this (and my mobo). Maybe some questions will follow

 

My T9300 tops @ 90C and idles @ 34C in a much smaller laptop (FSC 9200 is an 12.1' laptop).So I can't think that it is not a heatsink or paste issue. I don't like arctic so I used a Shin-Etsu.
What's the part No of your t9300. Mine is a SLAYY. Intel may used some different technology between one of the two.
