Hello,
On my Tyan S1830S "Tsunami" (a venerable AT mainboard, with AMI BIOS
V2.00.02), I recently replaced an Intel Pentium III 600E processor (Slot
1) with a PIII 1GHz (FCPGA Socket 370, product number RB80526PY001256).
Each of these "Coppermine" chips is of the 100MHz FSB variety, which is
the fastest the S1830S's 440BX chipset officially supports. (I also
needed an adapter, so I bought an inexpensive "Super Slocket III," off
eBay <http://www.ebay.com>.)
Anyway, everything seemed to go smoothly, except for the fact that the
new CPU only runs at 900MHz! The BIOS and various utilities [including
the latest version (7.1) of Intel's own "Processor Frequency ID"] all
agree on this issue, too.
The RB80526PY001256 is using a 9x multiplier (i.e., 9 x 100MHz =
900MHz), instead of the proper 10x, apparently. I've tried different
BIOS settings, such as temporarily increasing the FSB to 112MHz, which
results in approximately 1GHz (9 x 112MHz). Alas, that causes system
instability (e.g., AVI files always crash).
As all PIII's are "multiplier locked," how can I >safely< get the full
1GHz out of my purchase?
Incidentally, according to an Intel Web page, the RB80526PY001256 is
"for existing embedded applications using the Intel® 440BX chipset
only." Could this have anything to do with my current problem?
Please, reply to the newsgroup, exclusively; thank you, in advance, for
any helpful information.
Cordially,
John Turco <[email protected]>
