SOLVED FINALLY!!!

[dave]

Well guys, I finally did it, and boy am I glad I did. For those of you who didn't know, the new Celeron II's have a default voltage of 1.65V vs the older ones at 1.50V. So, needless to say the standard method of connecting the pins on the processor won't work. You need to connect the VID0, VID1, VID2, VID3, and Vss pins. So what I did was the standard wrap around VID0, VID1, VID2, Vss. Then I used the "staple" method to connect VID3 to the whole shootin match. The staple method won't work because in one of the holes of the socket you'll end up with three wires which won't allow the pin to enter, no good. The straight wire wrap doesn't work to good because of the configuration of all 5 pins makes it hard to get em all tight. So I used the combination, put the chip back in, with a minor amount of help....pushing, and booted up, doubtfully. Boy was I surprised to see the default voltage at 2.05V!!!! So I went into the menu of available voltages and when I saw that it ranged from 1.30 to 2.40V I damn near had an orgasm!! So now I'm running at 1.90V, 950Mhz, at 27 degrees C. I can boot at 1000Mhz and at 1045Mhz, but I'm still waiting for my Peltier cooler to get here first, don't want any extra heat. Good luck to you all.....WOO HOO!!!!

Well I decided since you had such good luck I would try. The od went very well booted up core V 2.05 (sigh of relief that I did not mess up and fry my chip) tried 2.05,2.10.2.20.2.30. Still can not get 100Mhx FSB not matter what I do no viedo no nothing going to try pc133 ram to see if that makes anydiff but I doubt it I even dissabled my L@ cache to see if that would help nothing . Thats it i am picking up a celeron 600 tomorrow

ya its a cool trick ..I usually just wire the vid3 to the vss and get 2.0vcore ,,seems like the celly 2's dont mind the voltage ,,my 566 has been there since may ai think ,or maybe april!

I am thinking about getting peltier but afraid of the danger of overheating my chip. Is there a really good website that talks about Peltier? The ones that I found were not that well explain. Anyway, where did you get your peltier and how much you pay for it?

If you need complete instructions and tips for insulating your peltier, then head on over to http://www.octools.com .. Octools have an article called "Total Peltier Condensation Prevention," which should do the trick! If your going to follow Octools instructions and do this from scrap (I find this the best way), then head on over to http://www.tedist.com and pick yourself up a peltier -- make sure you get a potted one. Depending on your processor, the Frost-74's work excellent for P3's, while AMD processors may require all the way up to a 172W Drift -- eek.

Have fun!

Where can I get a visual of how to do this and will it automatically raise the default? My Tyan board (in a secondary pc) has no voltage settings whatsoever, so I can't overclock my 533 to 800 where it was on my Soyo board.

Another question I might as well throw out is if there are any slockets that will let you manipulate voltage settings despite none being available on the board via jumpers nor in the BIOS. The one I use now is generic and only has jumpers to force the type of CPU installed...66, 100, 133, Auto, Single or Dual processors, Cyrix or Intel. This thing ran at 800 at default voltage on my Soyo but won't even post on this Tyan and it's bugging me.

Here's an article about wiring the pins:

The Abit slotket III has voltage jumpers to allow you to change the Vcore- most of the name brand ones do, I believe.

Hey dave...specificly which c2 were you using when you did this, and which MB? All the 600 cBo' are 1.5v, while all the 600 cC0's are 1.7v base core. I got shipped a 633 cBo by mistake instead of a 600, and indeed, it is 1.65v core default. I've beat my head totally against the wall trying to vid pin it. Before you get the wrong idea..heh, I've wire tricked probably 30 - 50 of these thus far (600cB and cCo) so i'm fluent with it. I initially thought I wasn't tying the wire off tight, but hey, after 9 trys, still nada. I searched the messages here and found your post, and tryed it too. No go. All it did was give me the vid3 - vss 2.05v default, which isn't a prob for me, but this cpu is for a customer. You can give it the 2.05v default without wiring all the pins, just the normal vid3 - vss, without wiring all the pins, i'd done that in and amongst all the attempts with the normal tricks to make sure I wasn't losing my tiny mind, just don't want my customer getting that type voltage as a base. Maybe i'm getting rabid in my old age, dropped to much acid as a kid, or whatever, but I can't for the life of me figure it out. I've got flat spots all over my melon from beating it against the wall. This 633 is a pretty sweet chip to, boots up 950 right out of the box, no prob, at 1.65v. I just want to see how far I can take it up. I'm currently up to 1093mhz/115FSB with a CUSL2 and 512 Kingmax TinyBga at 1.95v, I think I can pop prolly 118-120FSB with another volt.

I'm just a stumped puppy...

You may end popping more than 120FSB with another volt- the Design Maximum for the Coppermines is 2.1v. With the limited thermal contact area on these cores if you increase the dissipation that much it probably couldn't begin to cool itself under load!

Good luck, but keep the fire extinguisher handy...

 

[geek]

If you set the jumpers on a ASUS socket adapter for maximum voltage, then you have the full range of voltage adjustments in your bios setup. Most boards you have to set the voltage down in the bios because the socket adapter adds on to the setting (ie setting at 1.50v in the bios may yield 1.85v actual). The abit sh6 (intel I815 slot board) however expands the range in the bios so that what you set is what you get. My CII 566 (cCo) will boot and run good at 1066Mhz (2.1V). However, I can't get it to use the 4,4,1 setting so that the PCI multiplier is 1/4. As a result, the onboard sound doesn't work due to the pci bus >40Mhz. Any suggestions?

Agreed tim, but i've ran these c2's without a hitch at 2.2v. I'm just looking to hit 2.05v, within the 2.1v limit. Can't get that volt in the BIOS of a CUSL2 mb without doing the vidpin trick to it. I'm baffled by this, even after studying the pin array layout and reading the spec sheets at intel...i'm gonna figure it out yet.

Look this over-

I have done a lot of research into the PIII pinout lately for another project, if I can help drop me a line.
