The bandwidth is impressive. The quad channel performs well in tests. It's interesting you mention varying latencies making a difference. Others have reported similar observations. Personally, I struggle to spot the distinction between DDR 1600 CL9 and DDR3 2400 CL9. I'm not an expert in memory overclocking. Command rate acts like a latency adjustment; lower numbers mean faster operation. 1T is ideal, so keep it that way. Back in the day with DDR2, small changes in command rates could noticeably affect performance. Today, with DDR3, those differences are usually negligible except in synthetic tests, which seem more about theory than real-world use. Great insight. Thanks for sharing your findings. If you ever feel stuck, try testing a few memory modules and see how dual-channel boosts your results.
I ran additional tests just for curiosity. I lowered the CPU overclock to 3.6GHz, set the BLCK to 120, and reset the CR back to its default of 2T. Despite that, I reached 3200MHz while keeping RAM at 1.35V. CPU: 3.6GHz Cache: 3GHz (Stock) RAM: 3200MHz 16-16-16-36-2T
