GA-6BXC Rev 1.9?

I was given a computer with a GA-6BXC Revision 1.9 Board with a 400 Mhz
Celeron CPU. The only manual I can find online refers to Revision 2.0. I
have a PIII 650 Mhz I would like to put on this board but am not sure the
Revision 1.9 board will work with this CPU. I know the voltage requirements
for the two CPU's are different and am wondering if that is a problem with
this Revision 1.9 board. Any help would be greatly appreciated.

Thanks, Larry

Larry,

Gigabyte only shows Coppermine CPU support for 6BXC's at revision 2.0 or
higher.

However, here's where it gets interesting - your Rev 1.9 motherboard MAY
have the chip to supply the lower voltages needed for the Coppermine CPU's.
(My Rev. 1.9 6BXE board does, and it's been running a PIII-750 for years,
despite Gigabyte's list showing it won't work.) The voltage regulator chip
could be marked as a HIP6004BCB, or as a RC5051. It's located near the CPU
slot, and is a 20 pin chip. Also near a pair of coils, two switching
transistors and SW1, if you are into electronic parts.

If your 6BXC does have the proper voltage regulator chip, flash the BIOS to
the latest version before trying the PIII 650. Also, SW1 will need to be
changed from ON-OFF-ON-OFF to OFF-OFF-OFF-OFF to support the 100 MHz speed
of the CPU, up from 66 MHz. SW2 won't matter, since the clock multiplier is
locked in the CPU.

Other changes from Rev 1.9 to 2.0 - the addition of a set of jumpers to
supply more power to the AGP slot for high power graphics cards. (Voodoo3,
for example.) And the connectors for keyboard and mouse went from basic
black, to the more popular green and purple.

Hope this helps.
Bob.

Bob, thanks very much for your response. I greatly appreciate it. I sent
you an e-mail via your Yahoo address.
