Have you tested the CPU's and adapters separately?
Time to do some bench-testing I'd say 😉

And be sure your PSU is up to the task, though with a Virge or something similar, a 250W quality PSU should be enough to get the bugger booting up stable.

PSU is a 400W number (no name), but delivers 16A on the 12V rail. It should be plenty. I've swapped CPU's between the adapters but I don't have a tualatin board to test the chips themselves.

I also just tracked down a bios for the SE440BX that supposedly will allow me to make this work. That will be hot if so. I'll know tomorrow morning if it's successful or not. So it's now looking up again 😀.

Wish I could help but the only machines I could try mine in at the moment are my Dell GX1's and they require a special version of the PL-IP3 T which I don't have.

No dice on the bios revert on the SE440BX-2. It won't let me flash it 🙁

Also, I picked up a P3V4X, which I think I killed with a short. The weird thing is it sort of worked before the short, at least with a 1.4ghz celly (I think, didn't get to windows 98 to check it). Moving to a 1.4ghz PIII and it succumbed to the short I think.

There's a reason Powerleap is out of business. I think I've learned that the hard way here.

I once tried installing one of my Powerleap adapters into an IBM Aptiva tower I had laying around and it wasn't so successful, either. It wasn't seeing the P-III 1400 at it's correct speed. It was only seeing it at something like 450 or 466mhz. I figured out that the motherboard in the Aptiva only supports 100mhz bus and that the only 100mhz bus socket 3 CPU that would work would be the Celeron 1400, so I bought a couple of those but that was as far as my slocket experiments went. So I have two Powerleap adapters with P-III 1400-S chips in them, two loose Celly 1400's, and the Aptiva, or my Dell GX1's I can try to use them in. The Dell's need a special power cable that you can hardly find anymore, but you can convert the Dell to use a standard ATX using a special wiring harness and then you don't need the special Powerleap power cable anymore which is what I think I am going to try next.

Also, IIRC, the Dells had a special BIOS available.

The SE440BX-2 should work, but only with an older bios (it appears Intel modified the newer bioses to specifically fail with a Tualatin on a slotket). I'm not having much luck trying to go back to an old bios. Maybe they made it so that wouldn't work either, heh.

I've had more problems trying to make any of this work than I think I've ever had with hardware before. Usually it can take a long time and a lot of patience with non PnP stuff, but it's at least possible. Here, I keep hitting stupid road blocks that make it impossible.

And Yay!

P3V4X isn't dead. It had a short. Man that board is fussy. Still no dice with the PIII-S though (which is bad as I want the PIII-S not the Celly). At this point I'll settle for getting the Celly working and verifying that the board isn't screwing things up with CPUID. The board has an 8x multiplier limit in the BIOS, but I think it ignores that nonsense. I'll know more tomorrow hopefully.

That is good news 😉

I never knew Powerleap had such problems with their hardware, I always kinda regarded them higher. I thought they went out of business because the upgrade market they specialized in was disappearing.

The fact that the P3-S doesn't work but the Tualeron does either means the P3-S is dead (though easy to check by testing it in another board) or it may be some problem with the board not being able to correctly identify it?
The max 8x multi should indeed not pose a problem, at least not if you get your processor to work 😉

What you could try: If it's possible to set your board to manual settings, perhaps you could get it to work by setting the BIOS first with the Tualeron, then swapping CPU's. Try the P3-S first underclocked to 100Mhz FSB as I think it slightly increases your chance to at the very least get the board to post. If it does, you can continue from there 😉

If yuu keep having troubles with the board, then I'd suggest first trying to "test" the functionality of the board with a standard Slot 1 CPU. This will help you to tell if the problem definitely is with the CPU+Adapter, and not with the board itself.
