I bought a replacement supermicro motherboard off fleabay that has
dual Opteron 250 @2.4GHz. B The cpus have passive heatsinks, it is in
a supermicro 2U chassis with 4 front fans.
do you have the air shroud? this plastic thing that forms a "tunnel"
over the heatsinks? it is required.
No, the motherboard didn't come with that. B If I can find one will that
mean I don't need the active heatsinks?
Thanks!
As a followup, here's what I have done to try to alleviate this:
I bought and installed the plastic air shroud using the passive heatsinks
that came with the motherboard. B System still overheats and shuts down
within a couple of B minutes.
I bought 2 AMD brand active heatsinks, specific to this processor, and
installed them. B That meant I had to ditch the plastic air shroud, but the
motherboard manual says that active heatsinks are suggested for 2U chassis
and the air shroud was only $10. B I also used new heat sink compound when
I
put everything together.
System seems to run okay at idle. but make it work a little--like compiling
a kernel or tar-ing up a big file and the temp indicator comes on and
sysctl
reports
temps (on both the kate and lm sensors) finally exceeding 100 degrees C on
one processor, with the other is not that far behind at over 80 deg C.
At that point the system shuts down.
I'm at a loss as what to try next. B If I've read the AMD specs correctly
these processors should not exceed 71 deg C but I see temps near that at
inear dle.
Did I just get a lemon motherboard/CPU combo? B I still have a couple of
days
on my 30 day exchange if this is the case.
I'd get it all swopped out, something's very suspect there.
I've got 8 Opteron 250 servers at the office that I regularly pound
the heck out of (dist-cc cluster for bulk and repetitive building of
software) and the hottest we've ever seen the CPUs go was 42deg.
Thanks--that is exactly what I was loooking for.
I've e-mailed the vendor. With luck I'll have replacement or at least my
money back before long.
