Strictly speaking, the Ethlargment pill will work with NiceHash QuickMiner, but it is not needed as QuickMiner supports memory timings modification just like the Ethlargment pill.
We suggest not using the Ethlargment pill because the software is not signed and we cannot guarantee its safety.
You can read more about mining with 1080, 1080 Ti, Titan Xp GPUs and how to enable memory timing modification here.
