Yes, it should be fcpga, but not coppermine. Coppermines starts abaove
600 MHz.

Strange ! either they boot and works flawlessly or won't boot.

It can be that you have bad capacitors as many others have had.

You should check that the slocket is adjusted with a cpu voltage of
around 1.75 volt (not 2.0 volt as for your 566). There can also be
other important jumpers on the slocket.

Further in bios adjust agp ratio to 2/3 and not 1/1 as you use for
your 566. Else your agp card is overclocked with 50%. Pci divider
should be set to 1/3.

Thanks for asking.

No, I hadn't gotten that far into board architecture, have
no idea where mosfets are or what they look like.

Any tips much appreciated.

Cheers,

Congratulations John, you've just wont the prize for wrong answer of the
week. The Coppermine Celerons started (and the Mendocinos stopped) at
533MHz, not 600. Presumably you were thinking of Pentium!!!'s there. Also,
if it's FC-PGA, it *is* a Coppermine, so you've really got yourself in a
twist there.

Puddin': Your Celeron 566, *is* a Coppermine, despite what you may read
elsewhere!

Not necessarily. There are a variety of scenarios that could cause
"instability", from a damaged CPU to overheating to incorrect voltage and
more.

F*ck me John, that's a dangerous comment. You've just implied that the
original poster should be running his Coppermine Celeron at 2.0 volts. Let's
hope he doesn't take you up on that and overvolt his CPU, eh?

 > There can also be other important jumpers on the slocket.

Correct, like the ones that select between PPGA and FC-PGA, and the ones
that preselect the bus speed.

Yay, got that right, at least.

Puddin', if you're already running a Celeron 566, there's no fundamental
reason why you should be able to get an 850 working. In reality the 566 and
850 are practically identical anyway, they even have the same 8.5x
multiplier. In fact, you may well find that your 566 will overclock and run
at 850MHz anyway - many of them do.

If it's not stable, you need to chase down and eliminate the possible
explanations. Make sure, as John says, you've got the AGP and PCI dividers
set correctly. Make sure you've got the voltage set correctly on the
slotket's jumpers, and also that any other jumpers on it are set how they
should be. Also make sure that whatever thermal solution you use is properly
installed and working sufficiently well to vent the heat.

Also make sure that you're running PC100 (at least) memory!

Oh, it's fc-pga, I guarantee.

The thing was, the 566 was *identical* in all ways (same
color pcb, same color chip) as the Coppermine 850 save
the inscription ("850/100" etc).

The OP is no guru, but he knows better than 2.0v.

The Slotket was set all "auto" as it had been for years.
The SS bios was set to the proper (Intel) cpu specs. WCPUID
verified.

That's precisely what I thought.

In fact, you may well find that your 566 will overclock and run
 >at 850MHz anyway - many of them do.

Nix. I OC'd for about 5 years. The 566 was running at
850/100 for the last 3 years. Then it became unstable, did
some damage to my Win2k sp4 (see old thread "BH6 OC: Win2K,
multi-boot, instability." 12/15/04). When I set it back to
566/66 it ran flawlessly. Figure it was an overstressed cpu
due to goosed voltage (1.8, 1.9v.).

I'm controlling everything via the SS bios. This is 100%
practical? I never do anything inside the box without
verifying that all 3 fans are fully functional on boot.

 >Also make sure that you're running PC100 (at least) memory!

Have been since I built the system 5 years ago.

I have returned the Coppermine 850 for refund. It remains a
Grand Mystery as to why it ran unstable. I suppose it could
be the MOSFET (which I have yet to locate/identify), but I
dunno ...

Oh, and, yes, I carefully checked the capacitors on the BH6.
No evidence of a problem.

Thanks,
Puddin'

Here are the mosfets. You need to copy this into your browser. The
square components with the white circle around them are mosfets for
sure. Disregard the red circle it's not a mosfet.

 >> Stay informed about: BH6 and Celeron Coppermines 

Yes there are two of them like in the picture near the capacitors
between ports and CPU. They should be very hot to the the touch. If you
get really close there should be a part number on them also.

There are 2 of 'em, they are between slot 1 and the ser./par.
ports and on top of the long row of capacitors?

If I pull the case and put my po' eysball right on top of
'em, can I tell if they are 55N03 or 45N03 MOS-FET chips??

Thanx,
Puddin'

You are a good, good soul to nurse me thru this.

My education is ever continuing ...

Hi Little Richard !

I hope not you get problems with your nerves or general health in
future !

You should know, that everybody knows, that what one read on the
internet is not worth any reference at any time.

It might all be lies and jokes !

Just to make that clear !

Have a nice weekend

best regards

I wish we could start a new/separate inet and confine you
and a few others to it. Then your Great Prophesies of
Universal Nonsense could, indeed, be realized!!
