Testing Method & Test Setup
Performance memory is
worth the extra money only when it's used on a performance platform. These days, the name of the
game is Intel Ivy Bridge, so that would be our primary testing rig.

Our experience suggests that Prime 95 and HCI
Memtest is the couple of tests feared most by unstable memory. We'll select eight
750MB instance 100% pass of the latter as our yardstick for stability, as it is
relatively quick and familiar for us way of testing things.
Even though Ivy Bridge has brought a lot more flexibility to
memory overclocking in comparison with Sandy Bridge, it still
has a number grey areas which you can't reach manouvering with
available memory multipliers and adjusting the BCLK between 98
and 108MHz, the values we found out to be the extremes of full
stability. Because of that, we use a more flexible secondary platform,
which will also be used to verify the overclocking results which we
thought made little sense on the Ivy Bridge.

Unfortunately, due to memory controller limitations, which
regular users are also very likely to encounter, both our platforms cannot support
stable memory operation at frequency in excess of 1250MHz or DDR3-2500 so no testing
above that will be done.
