Test Setup
In order to thoroughly test memory as well as memory kits, we are using Intel's Haswell platform in combination with a highly binned Core i7-4770K
CPU. This allows use to drive the memory to a highest possible frequency and
therefore do proper scaling tests. Different memory chips (ICs) have different
sweet spots when it comes to primary timings, which is why we're altering CAS
latency, tRCD, tRP as well as tRAS settings. Overall we build five different presets,
which - as explained - can be different from ICs to ICs used on a memory module.
Other than that, we are also changing DRAM voltages, using 1.35V,
1.50V and 1.65V settings. There is actually a sound reason why we are using these
voltages as the 1.35V is most commonly used on ultra low voltage memory modules (ECO) and
low voltage memory also use 1.50V setting. The 1.65V voltage is the value recommended by Intel. 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 are running the HyperPi.
