Celeron Tualatin Voltage Pin mod(?)
yep, they should be connected. I think, it should be enough to connect both of them to VID25mV, this one is also connected to VSS.

Hello,
I'm in the same position as ncdesign; my German's a bit rubbish (despite a German mother!), and I just need a little confidence before I do this mod on my processor.
One little confusion is that the specs on the Intel site for my CPU number suggest it is a tB1 1.13 :unwuerdig: P3-S with a 1.5V vcore, but the CPU itself says 1.45V. The online manual for the :unwuerdig: P3-S suggests there are three versions of the CPU at each speed, but all of them have 1.45V vcore- the difference in the tB1 version is in the icccore.
I'm trying for a 1.25V vcore, so if I were to assume my CPU is 1.45V and connect the VID1, VID2 and VID3 pins, if it actually were a 1.5V vcore CPU, would I simply end up with 1.2V rather than 1.25V, which should be OK as well? (the chart in the manual is the same as for the celeron in this thread).
Also, is there any wire that is better to use for this; I have some fuse wire at different thicknesses; should this work well?
Thank you very much for any advice,
Frazer

If you have a 1.45V-processor, you only have to connect VID3 and VID2 to one of the others - so the mod you suggested is right. And as far as I see, you are also right - you should get 1.2V when you do this mod to a 1.5V-processor.
I don't know whether there are any wires better for mods. I just used a ribbon IDE-cable I cut off a wire. Then you have to take one of the wires in this one.
I don't think there are any dangers for the wire, so you can take any wire, don't care for the "thinness". You only have to care that it is not too wide between the CPU and the socket.

Thanks for the advice- and sorry for being so long in replying. Anyway, I tried the mod with very thin fuse wire, and it worked, giving me 1.25V, which confirms it as a 1.45V CPU I presume.
I'm now wondering though whether I could do the same mod on the pins of my Lin-Lin Tualatin adapter as well. Should that work, and if so, would you leave the CPU unmodified; in other words, would you treat the pins of the adapter as if they were the pins of the CPU, and only modify them?
Thanks again,
Frazer
