Test Setup
In order to thoroughly test memory as well as memory kits, we're making use
of Intels Haswell-E platform in combination with a highly binned Core i7-5960X
CPU. This allows use to drive memory at highest possible frequencies and
therefore do proper scaling tests. Different memory chips (ICs) have different
sweet spots in the case of primary timings, which is why we're altering CAS
latency, tRCD, tRP as well as tRAS. Overall we build five different presets,
which - as explained - can be different from IC to IC used on a memory module.
Other than that we're also changing DRAM voltages, wheras we're setting 1.20V,
1.35V and 1.50V. There are actually reasons why we're using these
voltages. 1.20V is the standard voltage for DDR4 memory. 1.35V on DDR4 is used
in case of slight overclocking and with 1.50V you can push the module by quite a
bit. Last but not least it
remains to be explained how we find out whether a certain setting is stable or
not. For that purpose we're running HyperPi.
