Overclocking will understandably be very much dependent upon luck of the draw with your individual kit. As such, we don’t assign too much weight to the overclocking results that we see with a sample size of one. There’s no harm in a quick tinker though.
Running at 1.35V for the default XMP configuration, we weren’t overly keen on pushing memory voltage higher when aiming to overclock. Unfortunately, not even a speed bump to 6600MHz was possible at the stock voltage. So, we had little choice but to push up to 1.4V DIMM voltage on our ASUS motherboard.
The best overclock that we managed was 6600MHz with stock timings at 1.4V. This is a reasonable speed bump of 200MHz over the already-lofty out-of-the-box frequency.
Thankfully, TeamGroup’s smart decision to include a temperature sensor will give some information as to whether the 1.4V operating voltage is reasonable for long-term usage.
