X40 overclock ?

#1 Post by Droider » Mon Apr 22, 2019 6:06 pm

Hi everyone,

I have been trying to overclock my X40 with setfsb without success. Is there a way to squeeze a little bit of more processing power ? Mine has 1.2ghz banias board.

I assume that your X40 has an ICS950813YGT phase-locked loop chip? That might be the reason why SetFSB was not able to overclock it.

Yes, by soldering pin 55 and pin 54 together on the phase-locked loop chip. This would give you an effective front-side bus speed of 133MHz (133MHz x12 multiplier = 1596 MHz), but it also has an unintended side effect of overclocking the memory controller hub.

Hello screamer, is there any way to overclock it a little without soldering ? :)

As far as I know, no.

There is no overclocking utility that I am aware of which supports the ICS950813YGT, so there is no way to overclock it via software. I'm afraid that you would have to resort to soldering those pins, if you seriously need the increased performance.

The other option would be getting an X40 motherboard with a CY28346-2ZCT, but it might be somewhat difficult to find.

I bought an X41 with a broken screen and housing for dirt cheap today. Just finished swapping the mobo into the X40. So far, everything is working as it should..Pentium M 1.5ghz dothan, 512mb ob ram, 8 cell battery (holds charge), mint keyboard. Upgraded the ram to 2.5gb right away. I am installing windows xp now just to update its bios. It is still on the initial bios release :)

Lucky me kinda overclocked the X40, one way or another :D

ps : i was so angry and careless after wasting 2 hours to take out 2 worn out screws, i managed to break the x41 fan connector pin while pulling it out. This video helped me a lot to salvage the 3pin connector from x40 fan and put it back to x41 fan properly.
