We have here some dual-athlon MP computers, and we're having alot of troubles with them.
My PC (2xMP-1800) hangs after more than 15 minutes of 200% CPU usage. I think it's because the CPU heats the memory modules.
Another one, used as a server, suffered a lot of crashes until we changed the case to a monsterous-looking thermaltake, and now it functions fine, but glows in the dark :) . This one is a dual MP-2000.


Both of the motherboards are tyan-tiger (i don't recall the exact model). One of them doesn't have thermal sensors at all(!!!), and the other one has thermal sensors, but linux has trouble reading those, requiring installing a buggy module. This module is responsible for several crashes on its own...

I've heard that the newer AMD chips produce less heat, so they may be a good choice. But counting on my experience, you don't want to use the above mentioned CPUs AND mobos.

1) I have to say that some of the biggest vendors in Israel are selling junk 
motherboards with their AMD servers, We have here a dual Athlon MP server, which had 
many problems, and it turned out to be the fault of the BETA-BIOS firmware!!!

Who in a sane mind would sell a mobo with BETA bios?

Anyway - I must say I am very happy with the performance since the bios update.

2) regarding overheating - my AMD cpu's usually run even cooler than the Intel 
equivalent, BUT - never remove a heatsink from an AMD... the sysadmin here removed one 
for about 3 seconds, and the cpu core blew up (white smoke and cracking noise) - this 
was with an Athlon-XP+2000

From my experience an Intel would just shut-down... anyone know if this is a motherboard feature or a CPU feature?!
