Pinmod dissappeared?? lol

Umm I did a pin mod about 2 weeks ago and now I'm looking at my cpu speed today and I notice it's going from 600Mhz to 1.7GHz as if there was no pinmod?? Could my wire have been too small and it's not making contact anymore?? wtf

I found mine would occasionally do that; I think it was when I resumed on battery, or used the wrong power adapter, or something...
If you reboot, it should be back to normal.

I rebooted...still low speed and I've also hibernated since the problem started, still messed. I'll try shutting down and booting off a different power adapter.

It wasn't working after I rebooted but I turn on the laptop today, and it's working!? Could the wire I used be too thin and only sometimes making contact?

no, i wouldn't think so, the pins are a really close connect with the socket...
like I said, I saw weird things like this happen periodically as well.... :-\
glad it 's back to normal though!

OK I figured out what causes it. If I come back from hibernate off of the battery (haven't tested a straight boot yet), it reverts to 400MHz bus!!! wtf...

EDIT: Damn...nevermind, that's not even consistent! It may have soemthing to do with me SOMETIMES using my busted power adapter.

First thing to remember is that not all chips are created the same and sometimes the pin mods are unstable. Something you may want to consider is trying a volt mod. For a 1.7 chip you shouldn't need too much more but maybe hitting one of the low voltage pins will get you more stable. There is information about doing this all over. It's been a long time since I looked at the layout for this but since you're usually stable, at least that's how it seems, you might be able to get away with just Vid(0), if that doesn't work try try Vid(1).

If you notice its doing it you should try using the battery power of the laptop and seeing what clocks the CPU uses on battery. Defective power adaptors can indeed reduce the FSB of any CPU.

Yes, I don't believe it's an issue of stability of the pinmod...it's not locking up. Just sometimes when it boots it boots as the 1.7GHz.

This is pissing me off. I can't get it to boot at 533MHz even with the good power adapter with or without the battery, etc, i've tried multiple times! I think my little piece of wire is failing... The first 2 weeks, I never had a problem. I grabbed the wire from some old headphones...could it have been insulated all around except the tips?? Where should I get the wire?

BUT if it is failing, why would it only happen between boots (i.e. Why isn't it locking up sometimes or crashing...) UGH I just booted one last time off battery alone and the 533MHz FSB is back...but not for long. Help me figure this out guys, where are the pinmod experts?

The easy solution to find out if it’s the wire, is to redo the pin-mod and see if it helps? I used the wire from a bread wrapper (burned the plastic from the wire), and my mod is rock solid with no problems. Of course, you don’t know if it’s just the chip itself giving you the problem. If you do decide to use the tie wrap from a loaf of bread, don’t use much as it is thicker than the wire from your headset.

Well when I tried pinmodding the 2.0 GHz proc I bought up to 2.67 that's what happened. Mostly would boot to 2.0 a few times booted to 2.67, and many other times hung at bios. And perhaps there's a lack of terminology on my part but if the mod isn't consistently holding I call that unstable.

I still say that you should try doing a volt mod. Back in the day a lot of people that couldn't get the mod to work initially were able to get it working by doing the correct volt mod.

Examining the document further, we find this table describing how CPU voltage is encoded by the pins VID[0] to VID[5]. Since raising voltage increases stability (while also increasing heat and power consumption), this chart will come in handy when overclocking, should the overclock prove to be unstable. If voltage modifications are needed, we can increase voltage by connecting any of the VID pins from 0 to 4 to VCC, the ground pin. Connecting VID[0] to ground results in a small increase in voltage, while connecting VID[4] results in a huge increase in voltage. I suggest connecting VID[0] when modifying a Pentium M 735 and connecting VID[2] when modifying a Pentium M 745. Should you choose to work with a 755 (Which we do not recommend), you will want to connect VID[3] to ground.

Also, the voltages in your sig, does that represent a software undervolt ( ican't remember stock voltages anymore)? If so, I'd at least set it back to stock voltage before doing losing any more sanity.

It has not happened recently. If I'm careful not to boot off the bad adapter, I'm hoping that's it. Will keep you guys updated if it happens again.

Yes, voltmod right now is undervolted :P

Alright, so it kept doing it once in a while even avoiding the fouled adapter all the time. So I decided to redo it with a different piece of wire. This one was thicker and probably aluminum as opposed to the other very thin copper one that I SUSPECT was insulated on the sides cause it came from a headphone wire.

Is the mod more stable now?

If that didn't work, I chopped up a bit of copper 16-gauge speaker wire stripped it and took one of the splinters that comprise the core of the wire. Was a little thick but it didn't bend any of the pins and it worked great.

Yes, so far I have not seen the 400MHz bus. Will keep you updated.

Still stable! Haven't seen the 400MHz bus since I replaced the wire...
