PLL Pinmod Overclocking Methods and Examples

can anybody point me to what needs to be done?

I would really appreciate help with this

This is a picassa album explaining how to do a 200-->266 oc. which means changing the fslb from H to L. it is for SLG8SP556V but they look alike a lot. If you can find your datasheet is safer to go on.
In your case you have to turn fsla flsb fslc from L to H. That way you are going to have H-H-H instead of L-L-L and overclock from 266-->300. I would suggest that if it is possible (no soldered cpu) you underclock with a pinmod from 200-->166 (L-H-H) and you only have to hardmod fsla from L to H. In that way if you have a succesfull oc at 300 you can remove the pinmod underclock and go further at 333MHz.
If you need further help ask. Be careful a small mistake can cost you, from no overclocking, to motherboard replacement .

Hey fellas,
Just posting a new message, Im not new to overclocking but I am new to FSB overclocking, Ive rescued a acer 4310 laptop from the bin and have been doing it up as a project and I want to see if I can get an overclock out of it. It has the 943gml chipset can support a max of 2 gb and has socket m. running a celeron m 520 atm but have a c2d t7200 on order which should be compatible.

I pulled it apart and checked my pll (rtm865t-433) and it is in setfsb and as far as I can figure based on the first post it is not tme locked.

While Im right at home overclocking on my rampage extreme Im not real sure what to expect from my current laptop setup.

I tried to install 2x1gb 800mhz sticks into the 533mhz motherboard thinking they would downclock and give some overclocking ability but I dont think the bios/motherboard is compatible with CAS 6, however I can run one stick at a time as long as I run it with one of the 512mb cas 5 modules that I have.

really this isnt a matter of if I should be doing it, Im just trying to figure out how to do it, Im an IT student just screwin around.

I also have some 667mhz samsung modules coming so I can run them. was hoping to get the 800mhz modules flashed with spdtool but they are hynix and as far as I can see they seem to be write protected (does this sound right or should I try to get around it).

What is a realistic overclock in setFSB, (maybe you guys already have some decent info on a page I havent seen yet that you could link me to.) I just gave it a go and tried to change it from 133 to 166 and the screen just went white straight away... maybe its not going to happen but I read the celerons overclock really good but I guess it could have to do with the ram. Anyway not too sure just looking for educated opinions.

Thanks for any help running 64 bit win 7 at the moment but thinking of going back to 32 bit because Im running under 2gb at present and shouldnt be able to run more than 2gb... Should I keep playin around or is it never going to work??

**got an overclock out of it but not much might be better once I get new ram**

how da f**k i GND this, its soo small 41pin.
here 2 pics bigger and smaller.
Green circle its just paint? maby to try broke this line with needle? and gnd somehow to this skrew hole?

Just disconnect the right leg of the resistor it leads to and connect this to gnd.
I think it will work this way.
You better not touch the pll legs or the line. I destroyed a motherboard this way.

Currently trying to overclock my Area 51 m17x

i found the ppl

ICS9LPR362AGLF

and i can succesfull overclock my T5550, 215x11 stock vcore no problems.

but..... my wireless and lan die the second i touch the pll setting, even if i put it at 166mhz

I guess the pci-e bus has no lock on it! Anything i can do about this? Would be a nice boost till i get a decent cpu!

[FragZero]

Got it working! if i use a different ppl first to read the clockspeeds and then the ICS9LPR362AGLF my wireless keeps working! Wired still stops works but that's not a real problem since my wireless is pretty stable. I'll post the pll which i use first when i get home.

Currently at 205x11, seems 215x11 wasn't stable in the end. Primed 1.5h at this speed.

I probably need more Vcore, currently at 1.25v and can't seem to raise it with throttestop, is there any other way or will i have to pinmod to get some more?

[moral hazard]

I dont know of any other way to increase the voltage apart from a pinmod.

[hw360]

I tried "setpll -read" on my ThinkPad Z61t (Intel 945GM/E Rev 03 chipset). It reports:
SMBus Read: Mode=BLOCK, Address=0xD2, Start=0x00, End=0xFF
SMBus error

Does it mean it cannot identify the PLL?

Thanks!

Update!

Seems it's not using another ppl first but going in standby - powerup and then using the ICS9LPR362AGLF to set the overclock.

That's with a T5550

Friend gave me a T7500 and i tried it, the ICS9LPR362AGLF doesn't work anymore.

Have to use the 9LPR363DGLF. Standby does not fix the network problem, network dies regardless of what i do. And it doesn't seem very stable - Sudden performance drops while benchmarking etc at anything over 200 fsb! No idea why it's this different with a 166 <> 200mhz fsb but fsb overclocking is totally worthless like this.
