The DIMMs were bought at the same time, are the same size, type and
manufacture, so I suppose the the DIMMs are identical
I only reinstalled the OS because I was playing with apt-proxy, and its a
new box so I'm messing around with it's configuration.
Anyway, I ran memtest86. It showed ERRORs:
- when I ran in dual channel arrangement
- when I ran memtest86 after doing "memory sizing" and "BIOS-All"
It did NOT show errors:
- when I ran each DIMM individually
- when I ran both DIMMs together in single channel configuration, BUT it did
seem to hang up at 97%, after running ~8hrs (maybe it had already looped
over the whole test suite)
