Which version of the P2B-S provides voltages down to 1.3 volts?
I seem to remember reading somewhere that it is rev 1.04 boards
that can do this. Is this true for all 1.04 boards?
Thanks

In the time it will take you to check the PCB revision and the
PCBA assembly number, you can just as easily check the top
of the voltage regulator chip. (I think it is above the 20 pin
power connector, and to the left of the slot 1 connector. The
numbers on chips like this typically have to be read with
reflected light, and it can take a lot of fiddling with a
flashlight, to get the light to reflect off the chip
exactly right.)
I found a HIP6004A chip on my board, which I removed and soldered
a HIP6004B chip instead. Not recommended unless you have nothing
to lose - I ripped one pad off the board in the effort, but
fortunately the pin in question doesn't do anything. I ordered
the chip from newark.com if you are looking for one. (I'd check
their website, but it is down for maintenance right now. I
modded my board in Mar. 2003, so it have been a while since
I looked at it.) My motherboard runs a Tualatin on an Upgradeware
slocket. I had to add microcode to the BIOS, using CTMC. And
use the latest beta BIOS before starting the mod.
