Got a very similar slotket, that works just fine with Coppermine. IIRC the socket connections had some waxy residue on them though, perhaps flux, or some kind of electronics grease that had dried up. Mine was new in box.

Rubbed the residue off and got it working by installing a CPU in the socket, and open/close the lever 30 times or so. Easy enough to try at least 😀

It is a Shuttle HOT-C003 - see attached info.
It supports Coppermine but in the lower half of page 1 it reads:
"max. 100MHz fsb, max. 800 CPU-frequency"

🤣 it worked, at least to some degree. I took out the slotket and CPUs dozens of times already and did not seriously believe in any remaining contact problems anymore. This time, I flushed the whole socket with WD40 and closed/opened it a couple dozen times with a CPU inserted. And voila: The Celeron 566 posted first try. It never did before no matter how often I inserted it. I also tried all other 370 CPUs mentioned above but still none of those work (they do work fine in a 370 CUV4X board). The 566 continues to work now even after unplugging/plugging the slotket or the CPU. So it seems your trick did indeed help!

@PARKE
Thanks! I'm tempted to believe that there has to be some headroom above the 800MHz to make the Celeron 900 run. And the EB800 should run with 100 FSB. Maybe I've got more contact problems.

@kaputnik, you made my day. Even though I have blisters on my fingers now.

Using your technique and making a mess with WD40 eventually brought all my 370 CPUs to life on the P3B-F. Even the Cyrix III 600, which never worked in any of my boards and thus I thought was dead, runs fine not only in that slotket but even other boards now. It was about time that I can finally enjoy the worst CPU the world has seen 😉

I'd never had thought that these shiny gold plated pins could have this much problems making proper contact.

Cool !
One more proof that you can never rely on what manufacterers say about their products 😉.

Ah, cool, glad to hear it worked 😁

You might want to clean that WD40 off with some electronics cleaning product, IPA, etc, that leaves no residue, though. Don't think WD40 ever evaporates completely, it might leave residues itself. There's no telling how it could affect the PCB substrate and components over time.

Yeah it does go sticky after a year or so.

I've got this exact slotket AND a P3B-f (and I'm not sure but I'd guess it's also 1.03). I'm currently running a coppermine P3 933 @140MHz fsb. Latest official BIOS from the Asus website. Rock stable.
