    BSEL Mod on a socket P explained with photos

    Hi guys.

    I succeded on upping the FSB on an Acer AS 4315 laptop from 133 to 166 and to 200MHz via pin mod :). The mod is simple, and can be done in 3-5 minutes if you can access easily to the CPU in your laptop.

    You can use electric wire to do the mod. I used a wire from an IDE cable.

    Note:
    BSEL / FSB mod doesn't with Intel Chipsets
    Undervolting mod works with all chipsets.

    UPDATE: 27/07/2009
    I updated the photos below because:
    1- The undervolting values of the T2060 were wrong. I was showing the T5300 values twice.
    2- There was a mistake on the photos showing the pin connection for Socket P.
    3- I added Photos to show FSB mod for both Socket P and M

    UPDATE: 04/08/2009
    I copied the content of post 81 here.
    UPDATE: 23/07/2010
    The BSEL mod will only work if you have:
    ATI GPU + SIS Chipset
    SIS GPU + SIS Chipset
    nVidia GPU + nVidia Chipset

    If the Chipset is an Intel one the cpu will be locked after the BSEL mod on its lowest multiplier

    Enjoy!

    UPDATE 15/02/2011
    I added a few diagram to show the following mods:
    FSB 133 -> 266
    FSB 166 -> 266
    FSB 200 -> 266

    Wow - you're the first person to actually pull this off, if I'm not mistaken.
    +rep and kudos, you've got guts, kid (2.6 GHz Celeron!).

    Does the Celeron feel any better/more responsive at this speed?

    Pin mod on PM965 will only via PLL possible. Intel MCH now has a intenal check of FSB. If the CPU FSB isn´t the same like stored in MCH then the Multi will locked to lowest. So if mod the PLL and cut the connection between PLL and MCH then the OC is sucessful.

    I played the same game with and without the pinmod and the laptop feel faster. I didn't run any benchmarks yet.

    Thanks for the info

    Guys

    1- Does the i965 chipset suppot 266 FSB?

    2- Can anyone donate a Celeron T1600 CPU?

    3- Is the T2370 faster than the T2500?

    I run some benchmarks and the Celeron M530 pin modded is as fast as a Core Duo T2300.

    UPDATE: 04/08/2009
    Benchmark photos removed

    If Tinselworm's running a Core Duo, it's got to be the 940/943/945 chipset series - they weren't released for anything else. Which is interesting, because I didn't think there was a 200 FSB setting for the 945.

    And no, the 965 chipset can't support 266 FSB, AFAIK.

    Just because you overclocked to it doesn't mean it can be pinmodded to that speed, nor that it's officially supported.
    That being said...DAMN.

    I'd be interested in trying this out on my Socket P T9500 (2.6GHz/FSB 200), PM965 chipset. If I could get the FSB from 200 to 266, then I could be running this at 3.4GHz.

    Nop
    I think he has an ATI Chipset (x200) but I need him to confirm that. If he had an intel chip his CPU would have been locked at it lowest multiplier

    What Chipset do you have in your laptop?
    Any photos of the mod?

    not when you have a celeron :rolleyes:
    I think this is because of the amount of cache on the CPU.
    Less cache = less voltage = less heat

    yeah maybe. When i ov my X9000, the temp gets 90°C in a few seconds. But that also depends on how many volt you give it. ;)

    Hmmm not sure, I will have to figure out what it is tonight, but it can definitly handle the heat.

    My Q9000 under 100% load on all 4 cores wont even hit 70c when overclocked to 2.8ghz via setfsb.

    This is max temp on a sustainted test with no additional cooling.

    how do you cut the connection to the MCH, is it just a pin on the PLL?

    @ naton
    Props to you for sharing about this cool mod :)
    I tried the pin mod with my AS 4315, Celeron M530, and I was successful with a 166FSB. However I was considering going for the 200FSB, but I would like to know what temperatures I might be looking at first. Is it a huge increase from the original 1.73Ghz?

    Also, what memory sticks are you using? - Mine are 2xPC2-5300 (333Mhz designated at max, according to SPD in CPU-Z), would it still work with a FSB of 200, or is entirely dependant on what your memory sticks can cope with?

    /Regards, net

    Memory frequency and FSB are completely independent. You do not need to match memory to FSB frequency (1:1), although it is nice.

    Hey everyone i have a GM45 chipset and a T4200 socket P cpu (2Ghz,800FSB,1Mb L2) I did see the mod for socket P but i didnt know if the chipset diffrence was a big deal? also does this mod change the FSB or the cpu multi.

    I'm not sure about how it works with the 45 chipset, but pin modding changes the Front Side Bus. The multiplier is constant, and except in the cases of Extreme Edition processors, cannot be increased.

    Do you think that it will work the same bc of the socket being the same? do i fallow the mod to a t or do i have to do anything diffrent? I really want to try this out even if i have to buy a new cpu or mob.

    yes, follow it to a t.
    the only difference is how your chipset would react.
    my chipset would force the lowest multi, so making this mod useless.
    your chipset may be different but since it is also intel like myne I wouldn't get my hopes up. the best pin mod is a PLL pin mod. pretty much always works, but it's difficult because the pins are small. I will do it to my laptop soon, just wanna know how to cut the connection from my PLL to the MCH.

    I have the same type of memory as you (i.e. 2 sticks of PC5300). The Acer AS4315 Bios will set the memory multiplier to he right ratio when the FSB is upped to 200.

    Temperature wise, between 42c and 60c depending on the load. The cooling system in Acer laptops is very good.

    There no risque on doing the mod. The worst that can happen is that your laptop would reboot itself every 5-10 seconds. This usually happen when the wires are not in the right holes or when they are in contact with CPU pins that they should be in contact with.

    Resetting the wires will solve the problem.

    Try and let us know if it works

    Question:
    I thought that the GM45 support only 200 and 266FSB?

    The pin mod for 266 is done by using the short/small wire only.

    Could voltages be modded with a pin mod? I know its probably unlikely but im just wondering.

    just tried with my setup in my sig
    changing fsb to 166MHz, it wouldn't boot at all.
    try to vmod VID4, it will hang when entering windows and rmclock run.
    After disabled it on safe mode, can enter normal mode, but no changes on its voltage.
    So now revert to original.

    intel chips are bit funny and the FSB mod won't 100% work unless your using a CELERON M

    I think the VID4 worked in your laptop and this why you had trouble booting in Windows.

    What makes you think tha there are no changes on the voltage?

    After VID4 the voltages on RMclock should be read - 0.2v

    read the thread below and download the PDF in the first post. It explaines in details what happens when you do the volt mod

    because after done the volt mod, when starting windows,
    rmclock is set autorun, the windows just freeze without anything can be done.
    So I try to go safe mode and disable rmclock autorun, and reboot.
    This way I could enter windows, using cpuz, there's no difference voltage, still 1.263v, the same without volt mod and rmclock is not running.
    When I tried to run rmclock, windows instantly freeze.
