"When users overclock their computer memory, they are literally compressing the size of the Data Eye and changing the waveform at multiple levels by running at a higher frequency and as a result, more data can be transmitted over a set period. However, this takes away pre-established safety margins.
It’s a “Dark Art” because overclockers cannot observe or visualise the multi-dimensional factors at play; instead, they are looking for signs in stability, the general “feel” of the system and good old trial and error as each factor can and will interact and influence countless others, settling a new wave equilibrium.
Generally, raising DRAM voltage allows for faster memory speed, “ but that also depends on the architecture of the chip too” explains Brett Williams, Senior Marketing Manager in Computing at Micron Technology.
