X31 Overclock?

[kryptonpwx]

Is resistor mod applicable for X31 overclocking?

My X31 comes with Banias 1.3 and only supports 3:4 for host/memory speed, so DDR400 will be more than enough.

If it is applicable, where is the resistor and where to move it? Anyone has tried?

Did you try using software called setfsb? I'd think overclocking using software would be safer than doing hardware mods.

Here is a link for it.

And it really works.

X31 is using CY28346 PLL, which only supports fine tune in CPUcool. It means AGP/PCI freq will increase with FSB since the dividor does not change, and it might leads to PCI and IDE device working improperly. setfsb is similar to CPUcool.

Resistor mod only overclocks CPU FSB and accordingly memory (since X31 only support 3:4 memory clock, most DDR333 SO-DIMM will sustain @ 354), and does no changes to PCI and AGP freq. It is safer assuming the mod is successful.

Wow!

If you ever do it please!!!!

Post a tutorial with pictures, as a X31 owner i found this very interesting.

If that's what you've used on your Z60t, then it looks like it does indeed. I'm playing around a little bit with it right now on my T40 to see how much I can safely overclock my 1.5 - am running it at 1.7 with hardly any difference in my NHC temp readings (if that means anything), but I'm not sure whether the Banias would cope with as big an increase as you've done with yours.

Kristian,

No what i did to my Z60t was something different, it's called pinmod.

[KristianJ]

Yeah, I typed overclocking into the search engine and found that out after I posted. I think I'll stick with the software solution for now, because I've spent a fair bit of dough booking holidays in October and I can't afford any more hardware mods for now.

Hello,

A little up for this thread.

I've tried SetFSB, and my PM 1.4 GHz can run stable @ 1540 MHz.

I've downloaded SetFSB for the X31 here :

http://www13.plala.or.jp/setfsb/downloa ... ad-X31.zip

I've installed it in my Program Files folder. (C:\Program Files\SetFSB)

Then I've edited my registry, to add a start entry.

KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
"SetFSB"="C:\Program Files\SetFSB\SetFSBu_ThinkPad-X31.exe -s110 -w1"

I tried this resistor mod on my x31 Y1Y 1,6ghz.But no success.System starts without bios battery only and wont start past F10 (save changes)
