Can P/III really work with 6BB?
tne...@cs.uah.edu
I know that Soyo claims that the SY-6BB motherboard
supports the first-generation of Pentium III CPU (at least up to
550 MHz) on 100 MHz bus. Has anyone out there actually
gotten the 6BB to run stably with a P/III? If so,
please post or email experiences. I'm interested in
which version of the BIOS you used and what size power
supply and what type video card you were able to use.
Is this board stable with P/III as CPU?
Thanks!

celeron 466 (370 with adaptor). When I install a PII 333 everyting run
ok, and when installed the celeron 466 and its adaptor in an IBM PC
it also run ok.
I tried with several video cards, and AT cases, and allways the same
problem.
Which are the acceptable celerons socket 370 for a 6bb v 1.0?
Thank you,
Bruno

work (or even fit into the socket) on a IBM PC (that would be an 8088 or
8086 CPU). If a Celeron 466 wont run then I'd suspect the CPU or your
Slocket (recommend using a Soyo). Any non Coppermine core Celeron will work
(that's up to 533MHz), Coppermine core should work, but I've not tested.

I have a 6BB V1.0 with Bios 1A6. With Cel400 it runs fine.
With a P3-550 it crashes some seconds after starting a 3D game.
At 83x5,5 = 458 MHz it runs stable. I tried a bigger
power supply but it didn't help.
The P3-550 CPU works fine in an ASUS board.
Next weekend I'll test a P3-500....

I am a little confused concerning the compatibility of the 6BB V 1.0 with
Celeron II chips. Chips like the Celeron 533A and up are based on the
Coppermine core and I believe at least partially support the SSE instruction
set. The tech notes on your web site (from Soyo) state that the 6BB's BIOS
is not compatible with the Pentium III E/B series (Coppermine). Therefore
while it is safe to assume that this also applies to the Celeron II, have
you tested this yet? Your comments below seem to imply it might work.
Thanks

With a P3-500 I had the same problems. I discovered
that the Bios doesn't contain a microcode update for
the P3 CPU.
BTW: Windows NT makes microcode updates when it boots.
I found the inoffical tools and the latest mircocodes
in the web and added it to the Bios. This works fine
but it wasn't the reason for my problem.
Then I made experiments with different RAM configurations.
It works fine when I put RAM into DIMM1 and DIMM2, otherwise
it runs very instable. It dosn't matter what size of RAM
I use but it must be two modules and they must be in DIMM1
and DIMM2.
The manual says at 100MHz use DIMM3, 3+2 or 3+2+1.
Very strange ...

Without a new Bios it will definitely not run with any
CPU with Coppermine core.
Chuck Andersen
Which new bios? I assume from your prior comment
"the inofficial and latest mircocodes" you found
were not needed. So you are using a released bios
rev, which one?
Thanks!

A bios that we all hope for but I think we will never
get it from Soyo.

Using the tools I found you can add and remove
microcode updates to or from the bios resp.
I could add updates for coppermines too but
before the bios updates the CPU it checks
the list of supported CPUs and this list I cannot
change.
If you put a coppermine to a board whose bios doesn't
have it in this list, I would expect that it will stop
booting immediately.

follows:
Soyo 6 BB V 1 MB with latest Award BIOS from Soyo
192 MB Ram (Dimm 2/3; 64 MB + 128 MB)
PIII 550-100/512Kb L2
The PIII 600-100/512kb L2 CPU was not compatible with my motherboard.
One possibly important aspect of stability is the layout of internal
peripherals, memory, etc. to allow better air flow, reduce heat
stress/contact between parts, etc. Embarrassingly, another factor that may
have been causing instability in my system (hard drive boot failure related
to the function of the on-board IDE controller) was the presence of a left
over case screw making contact with the motherboard. I don't know if this
was creating a short or if the problem resolved as a result of some other
action I took coincident with the screw's removal. In any case, given all
the gyrations I have gone through with my system lately, I am thankful it is
finally stable and I can reap the performance benefits of my upgrades.
Actually the system is now more stable than when it had a Celeron 300A (not
overclocked) and one 128 MB Dimm (Dimm 1). The PIII chip seems to run cooler
(or again, perhaps this is a byproduct of a better heat sink).
