VID PIN modifications... question.

[Pinky]

OK. Think I found the pins on page 61 here (ftp://download.intel.com/design/celeron/datashts/29859602.pdf) (thanks for saving me the trouble to find it Placid), but based on the information on page 21 I think I have to 'jump' VID2, VID1, and VID0 since VID3 and VID25mv has to be 'open.' I'm still learning about this, it's only been 20 minutes :p !!. I am confused as to how jumping in series is going to cause the chip to run at voltage X.

What's the best way of going about this. I have no soldering iron/equipment, though I'm thinking to get some, I don't think I need it. Is it possible to place wire (very thin gauge wire) between the holes or do I actually have to wrap the wire around the PINs? Any other suggestions and double checking my 10 minute investigation of the specs sheet would be helpful too, hate to have to pull my old 1ghz form the shelf and lose $134 on this one (if you know what I mean :p).

Pinky,
Here is a link to the cusl2c forums that will hopefully give you some more background: http://www.asusboards.com/forums/showthread.php?threadid=7009

Here is a quote that I made in that thread. The page numbers I referenced may be off by a page or two because I was looking off the PIII Tualatin data sheet and I would guess you're referencing the Celeron Tualatin data sheet. Hopefully this will help

"The voltage chart is on page 19. If you look at the 1.475V setting you will notice that only pins VID0 and VID1 are connected to the VSS pin(it's done internally and there's no way to change it). If you then take a look at 1.675V you will notice that the only additional pin that is connected to VSS is VID2(all the other pins are the same). You can indirectly connect VID2 to VSS by actually connecting VID1 to VID2.

To see where the pins are located, you can get a diagram on page 59. Notice that VID1 and VID2 are both pretty close to the edge and easy to get to. There's probably no way to wire VSS to VID2 directly since they're not next to each other. Once again, connecting VID1 to VID2 does the same thing."

I also read the same exact thing from a link to anandtech's forums... I think it's worth a try :D.

Now to connect them, is it necessary to wire them or can I connect the PIN holes on the socket with wire?

[Placid]

You can put a wire in the socket holes but it has more of a chance of moving around.
Here is a link on how to wire the pins.

Uh, thanks.

I wrapped them, using a little of my common sense.

At 1.725 (which is actually like 1.750) vcore my temps are solid around 42C (idling or not)... case temps about 28C, ambient around 26C. Not too shabby, I think with some good thermal goop (yes, I concede it might be needed in this case) and a louder fan (like my case needs another of those ;)) I can probably get the temperatures down...

But really, by the time I need to worry about a heat wave, I'll be running dual AMDs :D.

Thanks for the help. I'm gonna tweak some more. I am a little concerned with raising the voltage any higher, especially with those temps. I will see where she plateaus and check back here.

If you choose to wire the pins ive found it best to wire them in a figure 8 pattern, looks better as well as gives you a little better chance of keeping the wires close together in case one breaks when you put the CPU back in the socket.

[Placid]

Good job Pinky:)
Those temps are well within reason, most amd athlons idle around 45c at 1500mhz with a good heatsink.

[Pinky]

Awesome results, she doesn't go any higher but who cares? I got a faster P3 for the same price I'm reselling my old one :p.
