1) Are all thermal grease compounds the same? Is there any real
difference among them in terms of thermal performance (thinking about
picking one up for the BX). Is it worth greasing the celerons *and*
the BX? The BX currently gets a little over ambient temp, not cold
2) When 366's run at 550, Q3A dies with "Received signal 11, exiting"
and I'm trying to figure out how valid it is to blame the non-ECC
PC133 256MB SDRAM in the machine.
3) On a freeze after 2 hours up @ 550, the bios had the temps at
33 and 31 C for the 2 CPU's and 37 C for system. Since it doesn't
look like the temps rise during running, are the lock-ups still
heat-related (possibly)?
4) ISA soundcard... is it really that big a deal (in terms of lockups)?
Will taking this lone ISA card out of the system help uptime?
5) Why do I get APIC errors even booting with "noapic" option?

(these are diff ones, just note how many of them bunch up in time)

Note that I'm not stressing the machine *at all*. Load average
around 0.08, no kernel builds, etc... the machine locked up after
3 hours of nothing of load (not even Q3A, as I can't get the DRM/DRI
stuff working right under 2.3.42 yet)
