BSEL Mod on a socket P explained with photos

[tianxia]

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.

woah! that's some beefy cooling!
asus says it has the x38 chipset, but who knows('part from asus). maybe have a look at the ich?

Weren't pin mods also possible with Pentium M's?

yes they are. There is a tutorial in the forum explaining how to do it.

[moral hazard]

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.

can you please provide more info?
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?

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

Hmm can i do this on my t5800 2.0 ghz intel c2d. Its rated fsb is 200

That was all the assurance I needed. Now I'm running my CPU at 200FSB, 2.6Ghz

Thanks!

Well done. My T9500 is running 200/800FSB and 2.6GHz as well, but it's a T9500 and that's its native speed.

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.
