Ok I'll give you that much.

But the flip side of that coin is that just because some people are having 
problems doesn't mean that it's defective hardware, or even if it is 
hardware, it doesn't by definition mean it's the chipset.

I remember when the Athlons first came out, and before I ordered my MSI, I 
did a usenet search on "athlon problems" or something to that extent.  I 
picked the board that seemed to only appear in response to peoples 
problems, with the owner saying "well I have an MSI-6167 and I'm not having 
any of those problems."  Soon after the athlons came out people were 
complaining all over the place about stability issues, hangs, crashes, and 
all kinds of problems.  As it turns out, the great majority of these 
problems were -other- cheap hardware used in building the machines and 
other forms of user error such as :

   1. Overclocking without adequate knowledge of how to do so effectively 
(I won't say overclocking in general because a great many people, including 
myself, overclock without any problems.)

   2. An in adequate power supply.  AMD is very specific about how much 
power the Athlon needs to operate, and so is nVidia about their AGP 
graphics cards.  Ignore these -requirements- at your peril.

   3. Incompatible or defective memory.  The original athlons required 
unbuffered PC100 memory.  People using PC66 memory or buffered dimms had 
problems, and they deserved them.

On rare occasions there are incompatibilities, and on even rarer ones they 
cannot be fixed by a new driver/firmware.  One such case I have 
encountered, between the KT133/686 and the Aureal Vortex2 sound 
cards.  This is a known problem, and will probably never be fixed, seeing 
as how Aureal is no more.  Since I wasn't going to be seeing any more great 
chips out of them, or even any more driver updates, I felt no great loss in 
replacing my Aureal based card with another brand.

That's good to know.  I have probably never noticed any of these problems 
because I only have one Athlon in the house with an IDE drive, and using 
the HPT370 I would assume it's not subject to the same problems as the 
non-raid integrated controller; there have been no problems with it, in any 
event.

Well I'm writing this on an Abit KT7, and it will be sent through my 
MSI-6167 smtp server when I click the button. ;)

I did not want to wait for nForce either, but I'm not in a big hurry to get 
more memory bandwidth.. I'm more awaiting more SMP options.  The Tyan 
boards may have a good reputation for being stable and reliable, but their 
current board is a reference design, and I'm sure other manufacturers will 
offer higher performance boards, hopefully with less integrated crap.

If I were to suggest a chipset manufacturer to avoid, it would be the ALi 
chipsets.  The "ALiMAGiCK 1" (they insist you write it that way) has been 
plagued with problems, as was their K6-2 chipset (ALADDiN).  OTOH, my VIA 
based motherboards (KT133 and MVP3) have all been trouble free.

Just seeing your email address made me think of something funny but totally 
unrelated.  At my office, the idiots who set up the internal network 
downstairs used IP addresses that were used as examples in some TCP/IP book 
or another, inside the 130.30/16 netblock, owned by aligent.  Do they 
change it when I bring this to their attention? Hell no.
