Correct

1.5v - as per the Slot-T instructions. Tualatin processors usually don't
overclock any better as a result of Vcore increases, so I usually test
the system to ensure stability at default voltage, then try lowering
Vcore. Most Tualatins run perfectly on 1.4v, some as low as 1.35v.

I have not done this on a P2B-S, so I don't know which resistor needs to
be changed - but it should be fairly easy to figure out by probing the
board with a DMM while referring to the application circuit in the VRM
datasheet. The formulas for calculating resistor values are also in the
datasheet:

The FSB jumpers on the Slot-T are for overriding the CPU's FSB request.
These jumpers have no effect on P2B-series boards because they ignore
the CPU and use only the FSB jumpers on the motherboard.

Example? I've never seen a Tualatin processor without a heat spreader,
unless it's been removed.

Can't help there.

I've had problems with so-called Universal Retention Mechanisms too. I
find that non-folding types usually work better with the Slot-T, and the
older one-piece types that wrap around the entire CPU slot are even better.

Getting close.... :-)

On a whim, I decided to pull out the box the P2B-S came in to see if
it had any nuts for the board. The box was empty, but while I was
there, I went through some other small boxes looking for the bag of
extra screws that came with the tower. In one box, I found a complete
Asus P2B cpu adaptor kit. Holy smokes. I thought I had not received
them with the board. I guess I missed it in my rush to assemble my
new PC in '98. I was very close to bidding on one of the two correct
adaptors on eBay today. How cool is that.

Anyone need some "universal" connectors?

I'm following your plans for adding a thermister to the heatspreader -
just placed an order with digikey. However, I'm thinking about
drilling a small hole right in the center of the heatsink, allowing
me to place the thermister in the sink over the center of the core
(drilled from the top) for a more accurate reading of the temp of the
core heat spreader. Do you think there might be any issues with this?
Also, any recommendations for a compound that would be well-suited
for sealing in the thermister, would conduct heat well, but not
electricity?

Hi P2B!


It should work quite well with most of the PCI-Cards. 36 and a third
MHz. My most sensitive PCI Card (AHA 2940) ran at 37,5MHz (ASUS T2P4,
P54C200). Over that, it did?nt found any SCSI devices ...

Heatsink is in. Pretty hefty thing.

Has anyone here checked how much they can overclock with serious
cooling? I've got two 70? peltiers that have sat in a drawer for
nearly two years now that I've yet to try out.

Thanks,
David
