It would be highly interesting to see just
what performance we could glean from this stick of memory,
initial reports are highly positive so lets move on toward
the test setup...

Memory Timings
Our test motherboard, the excellent KX7333-R
[VIA KT333 CE], has the capacity to test these sticks
to the limit. It's important to know what settings are
used as this can drastically affect performance.
Firstly, these are the settings that both
the Crucial and the Samsung can run at to ensure
an even test. Note that 'DRAM Timing' is set to By SPD
as any attempts to use the lowest possible settings for
these series of options resulted in unstable performance
on both brands of memory. When running at 133 FSB
frequency both brands could handle the most aggressive
timings available on this board, an impressive feet in
itself!
The missing bottom option, at the bottom
of the image above, is for DRAM Command Rate which can
be either 1T or 2T with 1T providing a real boost to performance.
As with the previously mentioned options, system use was
unstable on both brands running at 166FSB with 1T enabled.
The Crucial would lock the system upon booting while the
Samsung did reach Windows yet locked after a matter of
seconds. As we mentioned before, 1T was stable at 133FSB.
