In your article, you provided timings in the specifications table as 8-8-8-20. According to Kingston's webpage, KHX1600C8D3K2/4GX modules were tested to run 8-8-8-24 at 1600 MHz (see http://www.valueram.com/datasheets/KHX1600C8D3K2_4GX.pdf). Could you explain the difference? Are these the same modules you tested?
