Never said he was wrong, I didn't know the motherboard in
question is
limited to a 100 mhz bus. I just checked it out on the Asus
website, and
that particular board isn't compatible with Thunderbird 1400 C
(10.5*133)
processors, it only works with the 1400 B (14*100), which is
quite weird
since it allows to manually raise the FSB to 133 in the BIOS.
He may have to
set all his memory timings to the absolute minimums to do so
though, no
Optimal, or turbo mode etc.

The problem is the KT133, or in this case the KM133 chipset.
Even though
the bios of my old KT133 chipset board list FSB speeds all the
way up to
147MHz, they didn't work. The KT133A chipset fixed that. I
wasn't sure if
it was fixed in the KM133 or not. That's why I asked him to try
it.
Apparently it isn't. Not having tested the upper multipliers of
the
Thunderbird core cpu, I'm not sure if it has the 5th multiplier
bit to
allow multipliers up to 24x. It doesn't have an external bridge
for the
5th bit like the XP's do but it still may be a valid bit inside
the cpu.
If it is, then unlocking the cpu and using the pin mod would
give him
access to all the multipliers up to 24x. Of course 14x is
probably as high
as he'd want to set it, although uping vcore to 1.85v and 15x
might work
too, but I think they were pushing the core at 1400MHz even
though some
have claimed to get over 1500Mhz from an Athlon 1000 tbird. I
know I got
over 1300 or 1400Mhz easily out of mine, but don't recall which
it was and
that was on the old Kt133 chipset board limited to about 116MHz
FSB. That
was over 2 years ago so don't recall specifics.


Hi Wes and everyone else who replied,

Just to clarify;
The FSB control in the bios only goes to 110MHz, it can be
jumpered to 133MHz but is only stable at 103MHz maximum. The
memory is definitely running at 133MHz and is stable.

I'm going to try closing the L1 set with a pencil, but I think
I'll have to fill them first, because the cuts/burns look too
deep. Can I just use car body filler or something else like that
to fill them?

You're right Wes, the KM(T)133 chipset was released to run the
memory at 133MHz but the FSB was only stable at 100MHz and so the
speeds are set separately. The KT133a was the next release with
both FSB and memory bus being stable at 133MHz.

Wait a minute, I wasn't aware of any tbird 1400's produced with organic
packaging. What's the part number on the cpu and how many L1 bridges do
you see 4 or 5? The 1400 tbird should be a ceramic package and does not
cut down through the ceramic material. The part number should start A1400
if it's a tbird, and AX1400 if it's a palomino core XP. On XP's with
organic packaging I used super glue to fill the laser cuts. On ceramic
parts you should never have to fill anything ever.

I don't have the system here at the moment, please bear with me it
might take a few day but I will post back with the codes.
