amd xp 1900+
asus a7v400-mx mobo
ok now the temp on the cpu is not stabilizing at all. It keeps rising until
about the shut off at 65c not even while under a load. The cpu has a good
heatsink,fan,arctic silver 5 and a case fan. This only seems to happen when
the dip switches are set to 133mhz.
Although when it's at the default 100mhz it stabilizes the cpu temp at 55
but the processor is running at 1200mhz. any ideas?
The processor table I've got, lists two 1900+ processors. The Tbred
runs at a Vcore of 1.5V and the Palomino runs at 1.75V. I expect
the Palomino runs a lot hotter.

If I had to guess, my guess would be the DSW setting you are
using isn't 133MHz. After all, you claim to have a good
heatsink, properly installed, with fan on in. And, in my readings
of other people's experiences, your symptoms remind me of an
accidental extreme overclock. Check to make sure the DSW pattern
is OFF-ON-OFF-ON-OFF for 133MHz.
This isn't going to help you (immediately), but perhaps you could
tell me what clock gen is used on the board. The clock gen is
the big chip next to the floppy connector, and Asus likes to
use
www.icst.com chips. The part number starts with ICS and can
have a five or six digit number after that. Some of the parts
Asus uses are custom, and no datasheet is given on icst.com for
them. Sometimes they are members of a family, and using another
datasheet from the family is good enough. You can see a list of
all the clock gen chips they make here:

The only reason I want this info, is to try and figure out what
happens for the 28 other patterns of the DSW switches that aren't
listed in the manual. If you get your ONs and OFFs mixed up,
I'd like to read what the complement pattern of the setting
would cause the clock gen to run at.
The info is also useful for overclocking, in case you want
settings intermediate between the four major settings listed
in the manual.
Your problem could also be caused by a heatsink that isn't
sitting flush on the processor die. Athlons are very demanding
of the fit of the heatsink, and a slight tilt will cause them
to overheat in no time. Especially the ones that draw 60+ watts.
This is one of the reasons I like to fit the CPU heatsink while
the board is outside the case, so I can look around the edge of
it after it is fitted. Some heatsinks are easier to see than
others.
