The first step was to test the memory at its specified settings to set a baseline for further benchmark results. From there, the maximum memory clock was sought at stock voltage and timings to see just how much overclocking potential this kit has out of the box. As the table shows, 1008 MHz was the max stock overclock reached and is clearly nothing to scoff at while having CL4 timings.
The remaining tests show how well this kit works with a range of voltages at specific timings. The kit was tested at CL5, 4, and 3 timings to find the maximum stable memory clock at 1.8V, 2.0V, 2.2V and 2.3V each.
After the spec settings were tested it was time to see how far beyond the rated speed these modules would go and what voltage was required for stability. Amazingly, they were able to run at speeds of >1100 MHz at CL5 with a mere 0.25V bump from their rated 2.2V. I should note that this kit was remarkably able to reach 1152 MHz at CL5 with the stock voltage of 2.2V! With an increase beyond the stock voltage to just 2.3V, this memory is capable of reaching a stable speed of 1218 MHz. That's a 52% overclock! Buying a memory kit with a specified rating of 1200 MHz and CL5 timings will cost over $200 and even then the rated volatage will be >2.3V.
As the voltage scaling graph shows, this memory scales linearly with voltage, making this a good kit for anyone interested in low timings or high memory clocks. I should finally note that, while these results are a good indication of expected performance, no two kits will perform identically and that these results are not guaranteed.
