Asus P2B-F and P3-800 in slocket

[RS]

Asus's website says the P3 800 should work in "socket 370 with S370-DL"
with BIOS since 1013.004
I have flashed the latest bios.

So far the system is not booting. No BIOS on screen. No PS fan.

jumpers have been set to 133 X 6 (P3 says 133 on bottom)

Should a 133MHz bus speed P3-800 Socket 370 flip-chip work in Slot 1
adapter that was previously funcitoning in a different system with a Celeron
400 ? No name is visible on the slocket. Jumper has been left at "Auto" (as
to bus speed)

Thanks !

Probably not. You'll need a slotket with Coppermine support.

Thanks,

I did manage to get hold of a newer, "PIII, Coppermin/Cyrix/Celeron to Slot
1 Adapter" , and set it up for "Auto" ; Single CPU; and Intel.

Same result :-(

Any other ideas as to why the PS's fan is not turning? The case's front
LEDs light up till I kill the power.

Another question: Coppermines take a lower voltage than the older chips,
right ? How does the mobo know what voltage to send to the CPU ? Or is that
covered by the kind of leads it senses via the Slocket adapter ?

I have had no option to go into the BIOS. In any event this BX mobo had no
voltage settings in the BIOS that I know of.

Thanks !

Load on +5V too low (SPSs need a certain minimum load). I guess your
P2B-F still uses an old voltage regulator chip that cannot deliver
voltages below 1.80 V (and gives out 0.0 V instead, i.e. no load on
+5V). If your adapter allows setting the VCore, try 1.80 V.

Another question: Coppermines take a lower voltage than the older chips,
right ? How does the mobo know what voltage to send to the CPU ? Or is that
covered by the kind of leads it senses via the Slocket adapter ?

There are a number of (VID) pins to choose the core voltage.

I'm not familiar with slockets, but that's a 100MHz (max) FSB
motherboard, so you're apparently overclocking it. I don't know
whether that's causing the problem you're describing, but it could be
a problem at some point.

OK, I have put back my previously working combination: a Celeron in a
slocket from another system. This was working fine in the P2B-F a couple
of weeks ago when I tested it. But now, even with this CPU, the PS fan gives
a small sign of turning and stops !

Everything else is as before: CDR, Floppy, and test HDD are plugged into
the PS, as is the motherboard.
Video card, NIC, and modem are the only cards in the system. These were all
in their slots when testing the Celeron, which worked.

But not nothing works ... even with the previously working configuration.

What does that sound like ?

Thanks !

Unplugging all drives (one by one, with attempts in between) does not
improve the situation ... still no BIOS, no fan turning ... except a small
fraction of a turn when the power switch is pressed ...

News Flash ! Plugging in another PS ... just to the mobo so far ... has
allowed the Asus's BIOS screen to come up !

I see that it is Rev. 1010 ... and I need 1013 to use P3 800's. Whether
even that will work with the 133 bus version, I don't know. I'm fairly sure
they made a 100 MHz version of the P3 800 at that time (since I know for
sure the 1GHz P3 was made in both versions), as well. Since it's a BX board,
probably only the 100MHz bus speed is certified ... but the P2B-F has bus
speed jumpers going all the way up to 150MHz !

P2B-x boards typically support 133Mhz FSB pretty well, but you need
133Mhz sdram and a agp graphic card which can handle 89MHz AGP clock.
So, before you try with 133Mhz FSB, try running at 100Mhz, that P3
800/133 certainly doesn't mind running at 600/100.
Some early p2b-f boards can't supply voltages lower than 1.8V, thus you
need a slotket which allows to manually set it to 1.8V.
Latest beta bios is highly recommended.

Thanks ! Fantastic site with oodles of info. I see I have a board that has
the " HIP6019CB" ... and therefore can only supply down to 1.8 volts. But I
also read there where it may not be a problem ?

My coppermine slocket has no provision for voltage adjustment ... and I have
no idea where to buy one these days that does. They are not an item stocked
much anymore.

Existing memory is most likely PC100, since it dates from a time when that
was the norm and PC133 was more exotic and expensive.

Running the P3-800 as a 600 would be acceptable ... hopefully the voltage
thing would not be a problem ?

Will have to read that site more closely to see if there is any way to run
the non-Flipchip Celeron 400 and older slocket that I first intended to use.
It is not mentioned on the Asus site, but I could see no reason why the
jumper settings available would not cover it's range (66MHz and 6X ...
which I gather from reading that site, it is not necessary to set the
jumpers for mulitplier anyway ... unless it is an engineering sample).
Anyway that chip and slocket would not boot.

Any idea why that Celeron 400 would not boot ? It was tested in another
system, and passed.

Thanks !

You could pick up an Upgradeware slocket.

You need to do hardware modification either on the slotket or the board
to get this to run. A good idea would be to get a different slotket.

I can't see a reason why it shouldn't work. Maybe the slotket didn't fit
quite right in the board, those slots can wear out a bit over time. Some
really cheap slotkets also make problems even with ppga celerons afair
(signal integrity issues).

Thanks,

Right smack in the Knowledge Base for the P2B-F on Asus's site, an ealry
question speaks of 66MHz bus Celeron's not booting .... and some patch ...
