OhGodAnETHlargementPill work only for DDR5x memory cards - 1080 and 1080ti
1060 and 1070 dont increase hashrate by it
Check Youtube interviews with OhGodAGirl, she explicitly says that they can do it on all nVidia 10xx series cards.
It has NOTHING to do with GDDR5X. You can inject memory timings on ALL nVidia cards to tighten memory timings and get more performance.
They actually sell EnlargementPills for 1050/1060/1070, if you contact them you can get a quote.
OhGodAGirl also mentioned they have plans to do a mining pool in combination with a mining software with nvidia memory injection for all 10xx series cards.
