- using Memtest86+
Re: using Memtest86+
On the contrary, someone who doesn't know what/how to set
their memory to anything besides the default, should defer
to the combination of memory manufacturer's SPD programmed
timings, as read (and adjusted per the motherboard
designer's desires) and used by the bios.
It would be ill-advised to not use the default bios setting
until there is a specific reason to change it.
You are missing the point. If a premium was paid for this
"high end" memory, it should run at the default timings
which are those programmed by the memory manufacturer. If
those aren't stable it is beside the point whether lower bus
or timings are stable, because the premium price paid was
specificially to not have to use the lower settings/slower
performance. There is no reason to test at lower speed
unless still trying to isolate which part is the problem,
when the opportunity to RMA the modules is present.
This is a good point you make, but that is, unlike the
generic statement to use the defaults, a special case where
you know a specific reason to change from the defaults.
You are entitled to your opinion, but it seems a bit more
subjective about specific situations. In other situations
it is expected the memory timings are read correctly and
applied correctly already, it would only be a matter of
changing them after some problem or desire to overclock.

Another example: OCZ Gold Enhanced Latency DDRAM is sold as 2.5-3-3-5
(or is it 2.0-3-3-5?) DDR400 or as 3-4-4-8 DDR500. These two types of
DIMM use exactly the same DDRAM chips, and differ only in the defaults
programmed into the SPD ROM chip. In fact, if OCZ had bothered to
implement both settings in the SPD chip (like standard Crucial PC3200,
which defaults to 2.5-3-3-8 at DDR333, and 3-3-3-8 at DDR400), then
the DIMMs would be interchangeable between DDR400 and DDR500 FSB
speeds without the need to fiddle about with the timings in the BIOS.
